About the role
Role Overview
Senior Software Engineer (Founding Builder) at a stealth-stage AI legal tech company. You will be the next core team hire to help build production systems end-to-end with high autonomy and precision.
Hybrid setup: ~85% remote, but you must be able to be on-site for 3 nights every month in Miami or NYC.
Responsibilities
- Backend-first architecture and ownership: design and build complex platforms/products end-to-end.
- Build AI-native systems and infrastructure (design systems around AI rather than treating it as a feature).
- Implement LLM orchestration, agentic workflows, and MCP integrations.
- Deliver a high-quality end-user experience with a focus on elegant, convenient UX/UI, collaborating with a product-leaning counterpart.
- Operate in a regulated, high-precision domain where output correctness has real consequences.
- Ship production-grade systems quickly in a small, fast-moving environment with low maintenance/low ego.
Requirements
- Strong software engineering depth with a backend-first instinct.
- Proven ability to own complex platforms end-to-end and ship production systems you can stand behind.
- AI-native mindset: experience building with LLMs in production as infrastructure.
- Experience designing systems where correctness matters (legal, compliance, healthcare, or fintech are relevant signals).
- Ability to communicate precisely, flag blockers early, and work with high autonomy.
- Fully bilingual (English/Spanish).
Nice to Have / Signals
- Prior exposure to legal tech, compliance-adjacent data pipelines, or enterprise SaaS in high-stakes domains.
Interview Process
- Founder screen (25 min)
- Blind work sample
- Half-day panel (ethics + adversarial assessments)
- Social event with the team
Compensation & Equity
- Monster equity: 0.20%–0.99% of the business (as of May 2026), meaningful early-stage ownership.
