AI Application Engineer (AI FDE)

Raya is seeking an AI Application Engineer to build and ship LLM-powered features for its companion product. The role combines AI product development, safety and evaluation work, and full-stack engineering, with iteration informed by how users engage with the product.

Responsibilities:

• Build LLM-powered features and agents that make our companion genuinely helpful

(prompting, RAG, tool-use, orchestration)

• Design guardrails and escalation so the product stays safe, holds the non-medical line, and

hands off to humans when needed

• Build evals that measure conversation quality, tone, and safety — not just correctness
• Ship AI features end to end in our Angular / NestJS / Postgres stack, from the model layer to the

user-facing experience

• Iterate quickly on real usage; own AI features from prototype to production
• Handle sensitive health data responsibly (HIPAA-aware)
