Job summary

AZX is seeking a Product Engineer to own client demos from schema to pixel, including deployment and observability. You will work across chat surfaces, agent workspaces, and the app builder, collaborating with platform and design systems teams.

Enterprise readiness, accessibility, localization, and audit trails are core, not afterthoughts. You’ll own front‑end TypeScript, Node/FastAPI backend‑for‑frontend, Postgres schemas, deployment, and on‑call responsibilities.

Qualifications

• 5+ years of production experience with React/TypeScript, streaming UIs and high‑frequency updates.
• Hands‑on streaming protocol end to end (SSE or WebSocket) including debugging raw byte streams.
• True full‑stack ownership: shipped backend for front ends with auth, idempotency, pagination, race conditions, migrations.
• Enterprise‑grade accessibility and localization beyond a strings file.
• AI‑native working style with concrete examples of tool use and overrides.

Responsibilities

• Own the demo stack from schema to pixel, including deployment and observability.
• Collaborate with platform app builder, test sandbox, and design system to ensure consistency.
• Maintain chat surfaces, agent workspaces, and tool integrations across front and back ends.
• Develop the agent‑facing developer experience—CLI, deploy tooling, and manifests.
• Read backend traces and logs to debug issues across product, backend, and platform teams.
