What you’ll do

• Maintain the core: agent orchestration + document pipelines + versioning
• Ship end-to-end: Go backend + React UI (you’ll touch everything)
• Make it reliable: evals, guardrails, observability (no demo-only systems)
• Turn customer pain into product fast (you’ll talk to users)
  
  

What We Care About

• You’ve built and shipped real systems (Go/Rust preferred). You can own a subsystem.
• You’re strong on fundamentals: distributed systems, concurrency, performance
• You’ve shipped AI/LLM features in production, and you learn new things insanely fast and can prove it
• You have high attention to detail + high standards
• You have product taste: you notice UX/copy/states, not just code
• If you don’t know something, you figure it out in hours - not weeks
  
  

Nice to have: interest in biotech, healthtech, or any regulated industry

Research angle (optional)

We’re working on agent / domain-specific evals, new embeddings and indexing benchmarks, and may publish benchmarks / deep dives and submit to conferences / journals. If you want to help set standards for this space, there’s room.

Logistics

• NYC, in-person, 5 days/week (we build better together)
• Competitive base + founder-level equity (2–10%)
