AI Engineer – Full Stack & Frontend (React/TypeScript)

About the role

This position sits at the intersection of AI engineering and application development. You will build customer‑facing features from scratch while integrating and scaling the AI infrastructure that powers them. The role requires deep fluency in TypeScript and React, strong backend capabilities, and hands‑on experience building AI‑enabled products.

Key responsibilities

• Design, develop, and ship full‑stack features using React, Next.js, and TypeScript.
• Own end‑to‑end feature delivery, including backend API design, async systems, and schema decisions.
• Implement applied AI patterns such as Retrieval‑Augmented Generation, tool calling, memory, and multi‑agent workflows.
• Write evaluation pipelines to surface real signal and ensure AI components improve over time.
• Build and maintain design systems, motion, and interaction details that convey trust in AI‑generated UI.
• Collaborate with infrastructure teams on Cloudflare Workers/Durable Objects, Postgres + PGVector, LangSmith, and Inngest.

Required profile

• Demonstrated experience shipping production‑grade AI applications.
• Strong understanding of both frontend and backend development.
• Attention to detail in UI/UX, especially around motion, transitions, and edge cases.
• Ability to reason about system reliability when AI models behave unpredictably.

Required skills

• React, Next.js, TypeScript
• Async system design, API design, schema planning, scaling under load
• Applied AI techniques: RAG, tool calling, memory, multi‑agent patterns
• Evaluation (eval) frameworks for AI performance
• Design systems, animation, motion, UI performance optimization
• Data‑fetching patterns: TanStack Query, tRPC
• Cloudflare Workers/Durable Objects
• PostgreSQL, PGVector
• LangSmith, Inngest
