Own cloud partner integrations end-to-end including architecture, design, and maintenance. | 5+ years in software with backend and integration focus, proficiency in auth protocols, and ability to handle ambiguity. | About ClickHouse Recognized on the 2025 Forbes Cloud 100 list, ClickHouse is one of the most innovative and fast-growing private cloud companies. With more than 3,000 customers and ARR that has grown over 250 percent year over year, ClickHouse leads the market in real-time analytics, data warehousing, observability, and AI workloads. The company’s sustained, accelerating momentum was recently validated by a $400M Series D financing round. Over the past three months, customers including Capital One, Lovable, Decagon, Polymarket, and Airwallex have adopted the platform or expanded existing deployments. These customers join an established base of AI innovators and global brands such as Meta, Cursor, Sony, and Tesla. We’re on a mission to transform how companies use data. Come be a part of our journey! About the team Most providers make customers migrate their data to them. We're doing the opposite: bringing ClickHouse Cloud into the environments our customers already trust, so their data stays useful right where it lives. Those environments come in a few shapes. Some are major cloud data platforms that run ClickHouse as a native service, so customers get it without leaving the tool they already use. Some are BI and visualization tools that need ClickHouse to show up as a fast, first-class data source behind their dashboards. And some are developer and data platforms we connect through marketplaces and identity federation with a couple of clicks to link an account. The goal is the same every time: ClickHouse should feel like a first-class citizen in every environment. As the founding backend engineer, you'll set the technical defaults for this team. You'll have end-to-end ownership, but you'll also work inside the constraints of platforms you don't own: thin documentation, unfamiliar deployment topologies, and timelines governed by partner approval cycles. A lot of the challenge is engineering across trust boundaries you don't fully control. You won't be doing it alone. You'll work closely with the team's engineering manager and a small founding group that will grow around you, but you'll be the one setting the technical direction. If that sounds like your kind of challenge, let's talk. What you'll do You'll own an integration end to end: the design, the code, and the production system that keeps running after launch. You're setting the technical defaults a growing team will inherit, so the early decisions matter. Day to day, that looks like: Owning the architecture: auth and identity flows, multi-tenancy, how data moves and where it's allowed to live, performance, and what happens in production Running what you build. You'll be on-call for your own work from early on, before there's a dedicated platform to lean on, which means owning the infrastructure, CI, deployment, and observability behind it Working on top of external platforms you can't change, and being straight about which risks are yours to manage and which aren't Partnering closely with the internal teams whose services you depend on: asking clearly, agreeing on interfaces, and finding ways to keep moving instead of waiting around to be unblocked We'd also expect you to have opinions about where this should go, and to write them down. A lot of what shapes the team's direction starts as a doc. About you You don't need to have experience of every single point, but these are the attributes of someone who will perform well in this role: 5+ years building software, with a good chunk of it on data-heavy or integration-flavored systems Solid backend and systems instincts. You can reason about deployment topology, multi-tenancy, and data movement, and you're comfortable owning architectural tradeoffs you'll have to live with later You've worked with modern auth protocols, service principals, and identity federation, and you know how to get it right across a trust boundary You've built on someone else's platform and know what that's actually like: incomplete docs, unintended breaking changes, etc. You're comfortable in ambiguity. You can ship before the spec is finished, make sensible calls under uncertainty, and flag the decisions that'll be hard to undo instead of quietly baking them in. You're good with other engineers. Much of the work runs through teams you don't own, and you earn their trust by how you think, not just what you commit. You're mainly a backend engineer, but you're comfortable enough in JavaScript / TypeScript to jump in when it helps You use AI tools well and honestly. Reach for Claude Code, Cursor, Copilot, or whatever helps, and be clear about where you did and didn't You write well. Most of how we coordinate happens in design docs, PRs, and RFCs Nice to have None of these are required, but any of them would be a bonus: Familiarity with a major cloud data or analytics platform ecosystem Real depth in auth and identity federation, or experience shipping through a partner marketplace or certification process Experience designing multi-tenant SaaS platforms, or the isolation and deployment topology behind them Working knowledge of ClickHouse, or another columnar / OLAP engine The typical starting salary for this role in the US is $141,000—$208,000 USD The typical starting salary for this role in US Premium Markets is $157,000—$238,000 USD Compensation For roles based in the United States, the typical starting salary range for this position is listed above.

Design and build authentication and authorization platform services with protocol-level support and SDK development. | 4+ years backend production experience with authentication/authorization services and identity protocols. | About ClickHouse Recognized on the 2025 Forbes Cloud 100 list, ClickHouse is one of the most innovative and fast-growing private cloud companies. With more than 3,000 customers and ARR that has grown over 250 percent year over year, ClickHouse leads the market in real-time analytics, data warehousing, observability, and AI workloads. The company’s sustained, accelerating momentum was recently validated by a $400M Series D financing round. Over the past three months, customers including Capital One, Lovable, Decagon, Polymarket, and Airwallex have adopted the platform or expanded existing deployments. These customers join an established base of AI innovators and global brands such as Meta, Cursor, Sony, and Tesla. We’re on a mission to transform how companies use data. Come be a part of our journey! The Platform Auth team’s goal is to support our ‘one customer identity’ vision by providing tools, processes, and expertise for our engineering teams to create a unified access management experience while simplifying and standardizing engineering patterns in the space. We are looking for engineers to join our growing team! What you will be doing: Design and build the platform services that power authentication, authorization, and audit across ClickHouse Cloud. This includes a unified RBAC/ReBAC service, token issuance and session handling, and the SDKs that product teams embed to make authorization decision. Model permissions and access control primitives (resources, roles, relationships, policies) that work across ClickHouse, SQL Console, ClickPipes, and HyperDX. Ship the libraries and APIs that other engineers build against. Implement protocol-level support for SAML, SCIM, OIDC, OAuth2, and MFA/passwordless flows. Own the integrations that make enterprise SSO and provisioning work end to end. Build the audit and authorization-decision telemetry pipeline so every access decision is observable, queryable, and surfaceable to customers. Partner with product engineering teams to migrate bespoke per-product auth implementations onto the shared platform, and design APIs that make adoption straightforward. Carry the platform on-call rotation and own production reliability for systems on the critical path of every customer request. What you bring along: Minimum 4+ years building production backend systems at scale. Comfort with at least one systems language (Go, Rust, C++) and one application language (TypeScript, Python). Hands-on experience designing and implementing an authentication or authorization service. Examples include building a token issuer, an OIDC or OAuth2 provider, a policy engine, a permissions model, or an FGA/ReBAC system in the style of Zanzibar, OpenFGA, SpiceDB, or Cedar. Working knowledge of SAML, SCIM, OIDC, and OAuth2 at the protocol level and are able to implement them. Experience designing APIs and SDKs that other engineers depend on, with strong opinions on what makes them adoptable. Experience operating distributed systems at scale, including caching strategies, consistency tradeoffs, and multi-region concerns. Familiarity with identity vendors (Auth0, WorkOS, AWS/GCP/Azure IAM) as building blocks you've extended or integrated into a larger platform. Strong production debugging instincts and a high bar for systems that are easy to develop against. Bonus: You've built or contributed to a Zanzibar-style authorization system, or run an OpenFGA or SpiceDB deployment beyond the demo. You've designed a multi-tenant permission model that survived real customer requirements like custom roles, hierarchies, delegation, and ABAC attributes. You've shipped an SDK that product teams across an org actually adopted, and have opinions about why most internal SDKs fail.
