Founding Engineer
About The Position
Our partner is a stealth-stage legal technology company applying AI to plaintiff-side litigation at institutional scale, with eyes toward reinventing the way law is practiced end-to-end. They operate at the intersection of special situations litigation and litigation finance building infrastructure that doesn't yet exist in the legal industry. They raised a seed round that was 75% oversubscribed in February 2026, and they're building the team that will define how this company grows. Their engineering culture is small, deliberate, and high-stakes. This isn't a place where you hand off tickets and wait for feedback. It's a place where precision matters, where the domain has real consequences, and where the expectation is that you think in systems, not features. We're looking for a Founding Builder Engineer; the next person to join the core team. This isn't a job description for an engineer slot. It's an invitation for someone who has already proven they belong in the top 1% of their craft and wants to build something that matters. You'll work across the full stack — backend-first, owning architecture end-to-end, and with taste for elegant and convenient 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. The domain is regulated and high-precision. Prior exposure to legal tech, compliance-adjacent data pipelines, or enterprise SaaS in a domain with real stakes is a strong signal. You understand why a wrong output has consequences and you build accordingly.
Requirements
- Software engineering depth with a backend-first instinct
- Proven ability to own complex platforms and products end-to-end without hand-holding

- Worked in a domain where precision matters: legal, compliance, healthcare, fintech
- Understand what it means to be wrong in a regulated context
- Fluent in English and Spanish
- Live in or be willing to relocate to New York or Miami
- Valid work authorization
