Founding Engineer Location Miami, Fl Employment Type Full time Location Type Remote Department Katapult Labs Department: Sunlight Job Description: Hybrid Role: 85% remote, but requires 3 nights on-site in Miami or NYC every month. This is NOT a remote position. Candidates must live in these locations, have valid work authorization, and be fully bilingual (English/Spanish). Please apply only if you meet these specific criteria. About the Company 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. The Role 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. What We're Looking For You have Software engineering depth with a backend-first instinct. You're comfortable owning complex platforms and products end-to-end without hand-holding, and you've shipped production-grade systems that you'd stand behind today. You're AI-native by default. 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 operate at high autonomy, low maintenance, low ego. You communicate precisely, flag blockers early, ship in fast-moving environments, and don't need structure imposed from above. You've worked in a domain where precision matters: legal, compliance, healthcare, fintech. You know what it means to be wrong in a regulated context.
