Elayne

Build and own major systems end to end, integrating AI and LLM pipelines for estate settlement automation. | 5+ years production software experience, strong Python/TypeScript skills, ability to handle sensitive financial and legal data with correctness and integrity. | About Elayne $3 trillion in assets pass between families every year. In this $250B industry, the process behind it is still manual: faxes, phone trees, spreadsheets, and grief. It can take families hundreds of hours, often years, to get through. Elayne is the system that automates all of it. We're a YCombinator and Accel backed company building the AI platform for estate settlement, and families are already using it to get through one of the hardest moments of their lives. We have a real product in people's hands, a modern stack we move fast on, and a long list of challenging, interesting problems ahead. About The Role We're looking for a Senior Software Engineer to join our engineering team and own major systems end to end. You'll work directly with our CTO and the founding team, meaning you get real ownership: you influence what to build, build it, and ship it. Why this role is different Estate settlement operates on messy, high-stakes data: legal, financial, and institutional records scattered across dozens of systems that were never built to talk to each other. We’re here to bring peace to families with product that feels accurate and automated. You'll build agentic systems and LLM pipelines where correctness truly matters, because the outputs carry real legal and financial weight. And you’ll build thoughtful product where nothing has existed before. Turning estate settlement into something a grieving family can actually trust, is a fundamentally human and deeply challenging engineering problem. If you've been craving interesting human-centric product and AI problems with real depth instead of building another SaaS app, this is it. What you'll build Solving hard problems: agentic asset and inventory processing, LLM-driven extraction with provenance and confidence, and entity resolution across messy, multi-source data. Make AI trustworthy while dealing with legal and financial stakes. Integrations with the outside world: banks, government systems, legal entities, and data aggregators, stitched into a single real-time view of a family's estate. Brand-new product: some of the most exciting work is still ahead, richer loss support for families, partner interfaces, and plenty more on the roadmap. You'll get to take ideas from zero to shipped and influence what we build next. New systems and foundations: the backend and data platforms behind financial assets, document intake, and real-time progress tracking. And end to end efficient systems designed with sound architecture, observability, and the standards that keep us shipping safely with sensitive data. What we're looking for 5+ years building and shipping production software, strong in Python and/or TypeScript Extra points if you're a generalist who likes wearing many hats, or a former founder who knows what it takes to build something from nothing Experience with LLM pipelines or AI agents, or the ability and appetite to ramp fast A strong bias for correctness and data integrity, especially with sensitive and regulated data High-conviction and low-ego: strong opinions held loosely, and you'd rather seek what’s right rather than win the argument Comfortable in fintech, legaltech, healthtech, or other similar categories is a bonus, as is experience with Postgres and data engineering Real systems-design range: you make sound architecture tradeoffs under ambiguity and own problems end to end Logistics Full-time, in person with the team in New York City (3 days/week). Compensation: $170-230k plus equity, health insurance, a 401(k), and [additional benefits].

| ABOUT ELAYNE: Elayne is an Applied AI company reimagining how families organize, protect, and transfer their estates, from financial accounts and legal documents to digital assets and end-of-life wishes. We combine structured data, custom AI agents, and guided UX to make estate optimization and post-loss settlement fast, clear, and dignified. We integrate with banks, insurance providers, legal systems, and data aggregators to create a real-time, intelligent view of an individual or family’s estate. Then we proactively adapt to life events (like having a child or losing a parent), and automate complex legal-financial workflows that typically take families years to finish. We’re an Accel and YC-backed seed stage company, launched last year and we’re operating in a manual $260B TAM, with over $80T in assets expected to transfer in the coming decades. This is a greenfield market for AI, and we intend to define the category.

You’ll focus on mobile and responsive design, polish, and quality, contributing to customer-facing improvements that make Elayne more intuitive and reliable. Along the way, you’ll gain meaningful ownership, hands-on mentorship, and firsthand experience building at a fast-moving, early-stage startup. WHAT YOU’LL DO Build and ship full-stack features using React, NestJS, PostgreSQL (Supabase), and AWS Improve mobile and responsive user experiences across our app Test and QA new features to ensure reliability and polish Debug and resolve smaller issues across the codebase to boost developer velocity. Collaborate with product, design, and engineering to deliver customer-facing improvements quickly WHAT WE’RE LOOKING FOR Pursuing a BS in Computer Science or related field, graduating between May-Dec 2027 A builder’s mindset: you’re curious, proactive, and eager to learn Strong attention to detail, especially in design, UX, and quality Comfort working in a fast-paced, ambiguous startup environment Excited to work in-person at our NYC HQ. BONUS POINTS IF YOU HAVE Exposure to LLMs or AI agents Experience working with vector databases, embeddings, or external APIs Interest in prompt design, evaluation frameworks, or AI-driven applications WHAT YOU’LL GAIN Hands-on startup experience: work in a YC/Accel-backed company building a new category from the ground up Technical growth: sharpen your skills in full-stack engineering with guidance Real impact: ship features that reach customers directly and improve their day-to-day experience Mentorship & career development: learn from a small, experienced team and gain exposure to both technical and product strategy
