Raycaster (raycaster.ai) (YC F24) creates a document IDE for high-risk, regulated work in life sciences (CMC/Quality/Regulatory). The product transforms cluttered, versioned documents (PDFs, Word Redlines, tables) into a structured workspace where agents can search, cite, reconcile changes, and help draft.We are hiring a Research Engineer who can help define (1) the ship production system and (2) the research direction for the company. There is scope to publish technical in-depth information, benchmarks and papers from day 0.

What you’ll do: – Build and ship core agent workflows: orchestration, retrieval, tool access, railing, evaluation – Work on document pipelines + versioning + reliability/observability – Turn research ideas into production features (and sometimes the other direction) – Help design benchmarks/datasets for high-risk document tasks; publish tentatively

What we’re looking for: – Strong engineering fundamentals (distributed systems/performance/reliability) – Comfortable implementing and iterating on evaluation (not just demos) – Product flavor: you pay attention to UX details and can build end-to-end – Able to learn a domain quickly and ask sharp questions

Nice to find: – Pre-publication, open-source, or technical writing

Logistics: – NYC (Hudson Yards), in person 5 days/week – Compensation: base + founder-level equity (details in process)

To apply, email: Founder [at] raycaster.ai Include: A link to the work you submitted (GitHub/Project) and 1-2 examples of research/assessments you created (can be informal).
