Company Description
A stealth-stage legal technology company applying AI to plaintiff-side litigation at institutional scale, with eyes toward reinventing how law is practiced end-to-end. We operate at the intersection of special situations litigation and litigation finance — building infrastructure that doesn’t yet exist in the legal industry. We raised a seed round that was 75% oversubscribed in February 2026, and we’re building the team that will define how this company grows. Come join us!
Role Description
We’re hiring the next person on the core engineering team. You’ll work across the full stack — backend-first, owning architecture end-to-end — with taste for elegant, intuitive UX/UI while collaborating closely with a product-leaning counterpart. You’ll design systems around AI, not just use it: LLM orchestration, agentic workflows, MCP integrations, and infrastructure that treats AI as a first-class layer of the product. The domain is regulated and high-precision. Prior exposure to legal tech, compliance-adjacent data pipelines, or enterprise SaaS where a wrong output has real consequences is a strong signal.
What We're Looking For
You have software engineering depth with a backend-first instinct. You’ve shipped production-grade systems you’d stand behind today, and you’re comfortable owning complex platforms end-to-end. You’re AI-native. You design systems with and for AI — not around it. You’ve built with LLMs in production, not as a feature but as infrastructure. You communicate precisely, flag blockers early, and ship in fast-moving environments. You take ownership without waiting for permission and bring strong opinions held loosely. You’ve worked in a domain where precision matters — legal, compliance, healthcare, fintech — and you understand what it means to be wrong in a regulated context.
