About the role
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%)
-
Apply: send (1) GitHub / past systems you built, and (2) one paragraph on why you’re interested in working at Raycaster to founders [at] raycaster.ai
