Full-Stack Software Engineer6-month contract · 40 hrs/week ·

We're looking for a senior full-stack engineer to join a fast-moving product team building AI-powered tools for cultural intelligence. You'll work on an insights engine, script analysis features, and a contractor management system — owning features end-to-end from schema design to deployed UI, shipping from day one.

What you'll do

  • Ship complete features: design data models, build APIs, implement UI, and write tests
  • Build AI-powered tools for cultural analysis, document processing, and content localization
  • Integrate with LLM APIs (OpenAI, Anthropic, Google Gemini) and observability tools like Langfuse
  • Help redesign existing tools into a unified chat interface with tool-calling capabilities

What we're looking for

  • 9+ years shipping production web applications that real users depend on
  • Ability to architect and build complete systems from database to UI — no handoffs needed
  • Strong track record with React + TypeScript and Node.js/Express
  • Comfortable making technical decisions independently and owning the outcome

Nice to have

  • Supabase or similar BaaS platforms
  • Vector databases / pgvector and semantic search
  • LLM integration and prompt engineering experience
  • Document processing pipelines (PDF, Google Docs, etc.)

If you're someone who hits the ground running and takes pride in well-crafted, production-grade work — we'd love to hear from you.
