We're looking for a mid-level full stack engineer to build features end to end across a Python/FastAPI backend and a React/TypeScript frontend. A large share of the work involves LLM-powered product features: an AI agent that calls tools to read and write real project data, and pipelines that pull structured data out of messy documents.

Responsibilities

  • Build and ship full-stack features.
  • Create fast proof-of-concept work for demos and client feedback.
  • Extend the AI agent: add and maintain tools with typed input and output schemas, refine system prompts, and keep model outputs grounded in data from the database.
  • Measure LLM behavior with evaluation suites and use the results to guide changes to prompts, tools and models. Changes should be backed by evals, not hunches.
  • Improve document extraction and classification pipelines for PDFs, Excel, Word, and CSV files, including the LLM-assisted steps.
  • Build data-heavy UI: tables, charts, maps and streaming chat interfaces.
  • Write tests at every layer (pytest, Vitest, Playwright) and review teammates' pull requests.
  • Contribute to infrastructure as code and CI/CD when your features need it.
  • Required experience
  • 3–5+ years of professional software engineering, with full-stack features shipped to production.
