AI Application Engineer (AI FDE)

Apply at https://typify.dev/jobs/view/188

You’ll build the AI that powers Raya’s companion — turning LLMs and agents into a warm, reliable, safe

product experience. This is a hands-on, ship-fast, close-to-the-user role: you’ll build AI features, watch

how real moms use them, and iterate relentlessly — while also pitching in on regular full-stack work

across our codebase.

What you’ll do

● 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)

What we’re looking for

● Required of every role — our core stack: hands-on experience with Angular, NestJS, and

Postgres (or the proven ability to ramp into them quickly). Whatever your specialty, you’ll do

regular full-stack work in this stack, not only your focus area.

● Hands-on experience building LLM applications (agents, RAG, prompt/context engineering, APIs)

● Ability to ship AI features end to end and contribute to general full-stack work

● A product mindset and bias to ship — you care how real users experience the AI

● Instinct for AI safety, reliability, and evaluation

● Bonus: conversational/voice AI, fine-tuning and evals, healthcare or safety-critical AI, MCP

Please note that while Raya Health does not offer relocation assistance we (Typify) are happy to help.
