AgentPress is hiring a hands-on contract Full-Stack AI Engineer to build full-stack product, AI agent orchestration systems, embeddable widgets, and enterprise integrations.

WHAT YOU'LL ACTUALLY DO:

• Build and ship end-to-end features across Bun/Hono/Elysia backends, React/Next.js frontends, and PostgreSQL data layers.
• Work within our AI agent orchestration system: tool execution pipelines, RAG retrieval, multi-agent coordination, and real-time streaming via WebSockets.
• Develop and maintain embeddable IIFE chat widgets deployed across client environments with complex CSP and integration constraints.
• Interface directly with enterprise clients on technical integrations and troubleshoot production issues.
• Contribute to infrastructure: CI/CD, background jobs with BullMQ, caching with Redis, and monitoring.

WHAT WE'RE LOOKING FOR:

• Strong TypeScript across frontend and backend (TypeScript-first codebase).
• Solid React + at least one Node.js server framework (Bun, Hono, or Next.js a strong plus).
• Comfort with relational databases, preferably PostgreSQL.
• Ability to read an existing codebase and extend it without breaking conventions.
• Excellent written and verbal English
• Self-directed work ethic; experience with AI/LLM tooling, prompt engineering, RAG, or agent architectures.
• Prior work owning features end to end, preferably in a startup or small-team environment.
• Willing to overlap 4-6 hours on weekdays with US time zones.

NICE TO HAVE:

• Embeddable widgets / third-party integrations (CSP, CORS, iframe sandboxing)
