About the Role

We're building an AI-powered workflow platform that transforms unstructured document sets into structured, dynamic insights. You'll lead the ground-up development of the frontend and collaborate on the full stack, working independently alongside engineers who've built from zero-to-one before.

What You'll Do

1. Architect and build the frontend (React + TypeScript) for a high-performance, data-heavy application
2. Lay the foundation for a scalable Node.js backend (Next.js/Nest.js is a plus)
3. Work with AI/LLM-driven features (e.g., entity extraction, relationship mapping) and ensure seamless integration
4. Own the initial codebase—replace the existing PoC with a production-ready system
5. Collaborate with domain experts to refine UX for complex data visualization (timelines, filtering, knowledge graphs)

What We're Looking For

Must-Have:

• 5+ years as a lead/senior engineer shipping full-stack apps (React, TypeScript, Node.js)
• Proven experience building from scratch (architecture, testing, deployment)
• Comfort with Python (enough to interface with AI/backend services)
• Familiarity with modern AI/LLM concepts (you know what an "agent" is or can learn immediately)

Nice-to-Have:

• Background in document processing or domain-specific workflows (we'll teach you the domain)

Why Join?

• High ownership—you'll shape the core product
• Small, experienced team with zero-to-one expertise
