Role summary
Founding Engineer needed for an in-person role in NYC, 5 days/week. This role involves maintaining core systems like agent orchestration and document pipelines, shipping end-to-end features using Go for the backend and React for the UI, and ensuring system reliability through evals, guardrails, and observability. The ideal candidate has experience building and shipping real systems, strong fundamentals in distributed systems, concurrency, and performance, and has shipped AI/LLM features in production. High attention to detail, high standards, and product taste are essential. Experience in biotech, healthtech, or regulated industries is a plus.
### 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
