RevenueCat

Design, build, ship, and maintain backend product features for large-scale systems. | 8+ years backend experience, strong SQL skills, customer obsession, product ownership, and ability to ship high-quality code. | RevenueCat gives app businesses the infrastructure and tools to build, run, and improve their monetization. Since graduating from YC's S18 batch, we've grown into the default monetization platform for mobile. We're in 50%+ of newly shipped subscription apps, we process $16B+ in annual purchase volume, and we help everyone from a solo developer to the OpenAI mobile team understand and grow their revenue. We're a remote-first team of 150+ people across 25+ countries, guided by values we actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance. This isn't the right fit for everyone. The systems you’ll build here manage billions of dollars and touch hundreds of millions of end users, and we don’t take that lightly. You'll be expected to work hard and hold a high bar for what you ship, alongside some of the sharpest, most driven people you've worked with. If that sounds energizing rather than exhausting, keep reading. The Role We’re looking for a Backend Engineer to design, build, ship, and own end-to-end product features used by thousands of developers and hundreds of millions of end-users. This is a hands-on IC role. We want someone that loves shipping products, not just code. You are an engineer obsessed with the customer and passionate about software. You’ll take ownership from problem scoping to production rollout to long-term maintenance. You have both the engineering fundamentals to write performant systems that operate at huge scale near flawlessly and the product sense that doesn't let “perfect” get in the way of “shipped today.” About You You have 8+ years of experience as a backend engineer designing complex, fast-growing systems that didn't exist before you. You can write advanced SQL statements beyond basic SELECT and UPDATE statements. You hold a high bar for quality and instinctively know which details matter, but also are discerning enough to cut scope when needed while still delivering value. You’re customer-obsessed: you imagine yourself as the developer, product manager, or marketer using the feature or experiencing the issue. You’re a builder, not an implementer: scoping, prioritizing, and driving rollout in partnership with our Product team. This isn’t a role where you check off items from a detailed specification. You can quickly familiarize yourself with code you didn't write yourself and improve it. You're comfortable coding alongside AI tools like Copilot, Cursor, or Claude Code. You use them to move faster on the parts that don't need your full attention, and you're detail-oriented enough to catch when they're wrong. You’re scrappy and biased toward shipping. You’d rather ship a good version today and iterate than wait to ship a perfect one next quarter. You communicate clearly, both in real-time and asynchronously. We’re a fully remote team, and how you write is as important as how you code. You’ve shipped meaningful user-facing features to production, monitored their usage and adoption, and improved them over time. You write high-quality, well-tested code, debug issues methodically, and help raise the engineering bar through thoughtful feedback and mentorship. You act like a founder: you notice problems, propose improvements, and follow through fast. Ideally, you have: Experience in Python. Experience in PostgreSQL. Experience building SDKs. Shipped a mobile app with in-app purchases. Some experience with React and SPA applications. In the first month, you'll: Meet frequently with your team and mentor to get up to speed. Set up and get familiar with repositories, task management, and the dev environment. Implement and ship your first project. Get familiar with RevenueCat’s dashboards, logging, debugging tools, cloud providers, infrastructure, and general architecture. Learn about the mobile app economy and subscription-business concepts that shape our product decisions. Within the first 3 months, you'll Scope and work on projects self-sufficiently, end to end. Talk to customers or support directly to understand how the systems you own actually get used and where they break down. Learn the basics of incident response and join the on-call rotation. Participate in code reviews and contribute to reliability and quality across the codebase. Understand every product your team owns. Within the first 6 months, you'll Review code, write proposals, and contribute to architectural discussions. Contribute to your team’s roadmap and technical direction — the “why,” not just the “how.” Be the go-to person on a couple of your team’s focus areas. Have shipped a major product or feature, start to finish. Within the first 12 months, you'll Know all the major components of our system and be able to debug complex issues across it. Have your own initiatives for improving our products, grounded in real customer and business priorities. Spec and architect medium-to-large projects, gather feedback, and drive design validation and rollout plans. Mentor other engineers joining the team. Push the org to improve reliability, scalability, and performance. What we offer: Competitive equity in a fast-growing, Series C startup backed by top-tier investors, including Y Combinator 10-year window to exercise vested equity options A fully remote environment designed around autonomy and flexibility. 4-5 weeks of flexible time off annually Paid desk at a co-working space Workspace budget and continuous learning stipend Interviewing at RevenueCat Our interview process is rigorous on purpose.

Build and maintain advanced AI agent systems for subscription monetization platform ensuring reliability, observability, and customer-focused features. | 8+ years experience building production systems, strong backend fundamentals, experience with AI agents, and ability to ship high-quality, user-facing features. | RevenueCat gives app businesses the infrastructure and tools to build, run, and improve their monetization. Since graduating from YC's S18 batch, we've grown into the default monetization platform for mobile. We're in 50%+ of newly shipped subscription apps, we process $16B+ in annual purchase volume, and we help everyone from a solo developer to the OpenAI mobile team understand and grow their revenue. We're a remote-first team of 150+ people across 25+ countries, guided by values we actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance. This isn't the right fit for everyone. The systems you’ll build here manage billions of dollars and touch hundreds of millions of end users, and we don’t take that lightly. You'll be expected to work hard and hold a high bar for what you ship, alongside some of the sharpest, most driven people you've worked with. If that sounds energizing rather than exhausting, keep reading. The Role RevenueCat helps app developers manage subscriptions and make more money from them. Maybe you're an indie developer who doesn’t know what "conversion" even means, you just want your app to make money so you can keep building it. Or maybe you're a growth specialist at a company doing millions a month, and pricing experiments are already your whole job. Either way, you probably didn't get into this to spend your days staring at a dashboard. So we built two AI agents to do that work for you, or make you even sharper at it if you're already a pro. Enter Rico. Rico watches over your subscription business and can help you make sense of it, and act on what it finds. Say your revenue dropped last week. You don't need to go digging through charts to find out why. Just ask Rico. It pulls the data, explains what happened in plain language, and shows you how you compare to similar apps. Then it can fix things itself, like setting up a new plan or restoring a customer's access, with you approving the change before it goes live. Run a pricing experiment and Rico will read the results for you and tell you which version is winning. There are so many things we want Rico to be able to do! Then there's Astra. Astra is a specialized agent to build and edit paywalls, the screen that asks someone to subscribe. Most developers are not designers, and a paywall that actually gets people to tap "subscribe" is harder to build than it looks, so Astra helps you with that. Use it in our online editor, from the command line, or hook your own AI tools into it over MCP. You can see both Rico and Astra in action in our most recent product launch recap. This is a role for engineers who've built advanced agents that do actual work , not just a thin wrapper around an LLM. You'll ship agentic features to thousands of developers, and you’ll shape the foundation everything else runs on: orchestration, tool execution, context management, evaluation and human-in-the-loop controls. About You You have 8+ years of experience shipping production systems. You've built agents that other people actually use and the systems around them: tool use, structured output, context management, evaluation, orchestration. You have strong backend fundamentals. You've built systems that need to be reliable, observable, and secure.

Lead and integrate customer success, growth advisory, and enablement teams to drive adoption and success. | 10+ years in customer-facing roles with 5+ years managing teams and building scalable customer systems. | RevenueCat removes the headaches of building and scaling in‑app subscriptions. Since graduating from YC’s S18 batch we’ve grown into the default monetization platform for mobile: we’re in >40% of newly shipped subscription apps, we process $12B+ in annual purchase volume, and we help everyone from a solo dev in Brazil to the OpenAI mobile team understand and grow their revenue. We’re a remote‑first crew of 150+, spread across 25+ countries, and guided by values we actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance. If you want your work to touch hundreds of millions of end‑users (and help the developers behind them get paid), you’ll fit right in. The role We are looking for a Head of Customer Growth to build and lead the operating system that helps RevenueCat customers become better app businesses. This is broader than a traditional Customer Success role. It combines strategic account coverage, app-growth judgment, specialist advisory, customer education, product adoption, and scalable enablement. The goal is not to give every customer the same high-touch service. It is to identify where RevenueCat can create disproportionate value, deploy the right kind of help, and turn every successful customer intervention into knowledge that benefits the rest of the customer base. You will lead a multi-lane Customer Growth function spanning the CSM team, Growth Advisory, Growth Advocacy, and the emerging Customer Enablement function. The CSM Team Lead will own daily CSM execution. You will set the strategy, operating model, talent bar, investment plan, and measures of success for the function as a whole. For our highest-value customers, this means deep account context, growth diagnosis, stakeholder mapping, product-adoption strategy, technical-account coordination, and clear next-step ownership. For high-potential customers, it means identifying them early and providing the right help before revenue has fully materialized. For customers with specific growth bottlenecks, it means bringing in the right specialist. For the broader customer base, it means scalable education through Growth Advocates, lifecycle guidance, office hours, playbooks, templates, product nudges, and eventually dynamic next-best-action systems. Your job is to make Customer Growth one operating system rather than a collection of disconnected activities. Why we are hiring for this role now RevenueCat serves tiny indie apps, fast-growing startups, games, media companies, health and fitness apps, AI products, marketplaces, and some of the most sophisticated consumer app businesses in the world. The app market is top-heavy, so the human touch must be allocated deliberately. At the same time, a customer that is small today may become strategically important very quickly. Contract status and current revenue are necessary signals, but they are not sufficient. We already have many of the ingredients: CSMs, a CSM Team Lead role, Growth Advocates, Customer Growth Advisory specialists, Product, Support, Marketing, Sales, TAM, Data, and one of the richest datasets in app monetization. We need a leader who can turn those ingredients into a coherent function. What you will be responsible for Own Customer Growth strategy across the full customer base. Define how RevenueCat helps customers grow after they begin using the product, including named accounts, high-potential customers, specialist-assisted customers, scaled customers, and the long tail. Build segmentation and coverage. Use current value, future potential, adoption, intent, growth moments, risk, and strategic importance to decide who receives named CSM coverage, time-bound help, specialist advisory, scaled education, product-led guidance, or monitoring. Lead through the CSM Team Lead. Set the bar for customer context, account strategy, stakeholder management, growth diagnosis, adoption planning, commercial awareness, and follow-through. Develop the Team Lead and create a strong leadership bench rather than becoming the permanent CSM manager. Identify high-potential customers early. Work with Data, Product, Sales, Marketing, and Support to find customers with meaningful future potential before revenue alone makes them obvious. Govern Growth Advisory. Define intake, qualification, expected impact, output quality, follow-through, and reuse. Specialists should be deployed against specific high-value problems rather than become general-purpose consulting capacity. Make Growth Advocacy a customer-education channel. Ensure Growth Advocates turn real customer learning into authoritative one-to-many education for existing customers and the broader app ecosystem. Build Customer Enablement and Scaled Growth. Create the roadmap for lifecycle programs, templates, office hours, documentation, automation, product nudges, and next-best-action guidance. Drive meaningful product adoption. Partner with Product and Product Marketing so customers adopt RevenueCat capabilities in ways that help them win, rather than merely increasing feature activity. Create clear cross-functional decision rights. Define how Customer Growth works with Sales, TAM, Support, Product, Marketing, and Data without turning CSMs into AEs, TAMs into a catch-all, or collaboration into meeting theater. Build the customer-insight loop. Repeated customer questions should become product improvements, enablement, playbooks, benchmarks, documentation, lifecycle programs, and market education. Own the function. Set metrics, operating cadences, headcount plans, budget, organization design, executive communication, and the talent bar across Customer Growth. What success looks like Within the first month Meet directly with at least 15 customers across different sizes, growth stages, product footprints, and monetization models—including high-value, high-potential, at-risk, and scaled customers. Take point on at least two live customer-growth situations. Work alongside the CSM, Advisory, TAM, Support, or Product partner to diagnose the problem, agree ownership, and move each customer to a concrete next milestone. Ship at least one no-regrets improvement to a broken handoff, account motion, Advisory route, or customer experience rather than waiting for a complete strategy. Establish a clear operating agreement with the CSM Team Lead and act on urgent customer, talent, or ownership issues. Build a working view of the team, coverage, high-potential misses, lane boundaries, and metrics—deep enough to make decisions, without allowing analysis to delay action. Within the first three months Act as executive sponsor for a small set of strategically important or high-potential customers and personally lead at least two customer-growth interventions through a measurable milestone. Put the first version of segmentation and coverage into production on real accounts, then revise it from evidence. Run decision-oriented account reviews and a working Growth Advisory intake and follow-through motion. Ship the first scaled education or Customer Enablement program based on a repeated customer need. Make the first material changes to ownership, operating cadence, or talent where the current model is not working. Establish a customer-insight loop that turns frontline evidence into owned Product, education, lifecycle, or process actions. Within the first six months Maintain direct customer contact every week and own selected executive relationships while leading the wider system through the CSM Team Lead and specialist leaders. Operate a functioning multi-lane Customer Growth model with clear owners, live handoffs, and visible outcomes across CSM, Growth Advisory, Growth Advocacy, and Customer Enablement. Have the CSM Team Lead independently owning daily CSM execution, coaching, and account quality. Demonstrate measurable results from customer interventions and show that repeated one-to-one work is becoming reusable Advisory output, education, enablement, or product insight. Have shipped multiple scaled programs and made concrete hiring or investment decisions for the function. Within the first twelve months RevenueCat has a trusted, actively used system for serving high-value, high-potential, specialist-assisted, and scaled customers. Customer Growth produces measurable improvement in customer outcomes, meaningful product adoption, account health, renewal readiness, expansion quality, and customer revenue outcomes. The Head remains directly connected to customers and is a trusted executive partner for selected strategic accounts. The best customer work consistently becomes reusable product, education, and market leverage. The function has a strong leadership bench and a record of shipping improvements without waiting for perfect information. What you will need to be successful Approximately 10 or more years in Customer Success, Customer Growth, strategic accounts, Growth Advisory, product growth, lifecycle, monetization, or an adjacent customer-facing function. Five or more years leading customer-facing teams, including managers, senior team leads, or specialist groups. Evidence of owning an entire function or multi-lane operating model, not only managing an individual CSM team. Experience building or materially rebuilding segmentation, coverage, strategic-account, adoption, health, advisory, or scaled-customer systems. Strong commercial judgment around NDR, renewal risk, expansion influence, customer value, and executive alignment. Credibility with mobile apps, app monetization, in-app purchases, paywalls, checkout, pricing and offers, lifecycle, retention, experimentation, analytics, or a closely adjacent domain. Enough product and technical fluency to lead around a developer-facing platform while preserving clear ownership for TAM, Support, and Engineering. Experience managing both generalists and specialists. Evidence of turning repeated one-to-one work into scalable systems. Strong written communication, directness, and remote-first operating habits. Evidence of hiring, coaching, performance management, and raising the leadership and talent bar. Ideally, you Have led CSMs and advisory, education, lifecycle, or enablement teams together. Have scaled a customer-facing function through a major company-growth stage. Have worked in a hybrid self-serve, product-led, and enterprise business. Have firsthand experience as an app operator, growth leader, founder, or consultant. Have built product-led or tech-touch Customer Success programs. Have helped productize or commercialize an advisory or professional-services capability. What we offer: Competitive equity in a fast-growing, Series C startup backed by top-tier investors, including Y Combinator 10-year window to exercise vested equity options Fully remote and flexible work environment 4-5 weeks of suggested time off annually for mental, physical, and emotional recharge $2,000 USD for workspace setup and $1,000 USD annual stipend for continuous learning Curious about the interview process?

Since graduating from YC’s S18 batch we’ve grown into the default monetization platform for mobile: we’re in >40% of newly shipped subscription apps, we process $12B+ in annual purchase volume, and we help everyone from a solo dev in Brazil to the OpenAI mobile team understand and grow their revenue. We’re a remote‑first crew of 150+, spread across 25+ countries, and guided by values we actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance. If you want your work to touch hundreds of millions of end‑users (and help the developers behind them get paid), you’ll fit right in. The Role We're building an AI assistant that helps developers understand and grow their subscription revenue. It lives in Slack today and is expanding to our dashboard and API. It can pull real-time data, evaluate experiments, debug integrations, and explain what's happening in your app using natural language. We see a future where the majority of a user's interactions are either intermediated or automated by our agent. We're a team that's historically built deterministic CRUD systems, and we need an engineer who can build the foundational agent infrastructure that everything else runs on: orchestration, tool execution, context management, evaluation, and the trust layer that lets us give an agent increasing autonomy over things that matter. About you: You have 5+ years of experience shipping production systems. You have hands-on experience building with LLMs — not just prompting, but building the systems around them: tool use, structured output, context management, evaluation, orchestration. You have strong backend fundamentals. You've built systems that need to be reliable, observable, and secure. You are comfortable with ambiguity. This is an early-stage product inside a growth-stage company. The architecture is still being figured out. You are self-directed. You figure out what needs to be built, build it, and ship it.

Identify the biggest reliability or performance gap and start fixing it. Meet with the team, get set up with repos, dev environment, and debugging tools. Familiarize yourself with RevenueCat dashboards, logging, debugging tools, cloud providers, infrastructure management and general architecture. Within the first 3 months, you'll: Launch a brand new agentic feature to tens of thousands of developers. Own a core infrastructure area — orchestration, eval pipeline, tool framework, or the trust/permissions layer. Be able to scope and work on projects self-sufficiently. Learn the basics of incident response and be part of the on-call rotation. Within the first 6 months, you'll: The agent is measurably more reliable, faster, and capable because you're here. You've built infrastructure that the rest of the team ships agents with. Review code, create proposals, and contribute to architectural discussions. Have shipped a major product or feature. Within the first 12 months, you'll: RevenueCat is an AI-native company. You built the engine underneath it. Know all the major components of our agent system and be able to debug complex issues.
