We are looking for a senior full-stack engineer with proven experience in AI-powered document workflows.

Requirements

  • 5+ years of software development experience
  • Hands-on experience building production-grade AI document pipelines — not just LLM API integration, but full pipeline design and reliability
  • Comfortable working with legal/commercial document structures — contracts, agreements, leases — at a level where no explanation of the basics is needed
  • Experience with PDF processing: extraction, parsing, classification at scale
  • Comfortable in fast-moving, small-team environments with high autonomy
  • Familiarity with AI-assisted development tools (Claude Code, Cursor, or similar)

  • Nice to Have
    Direct experience in real estate tech or legal tech products
    E-signature or document execution workflow experience
    Background in deal or transaction management platforms


Key Responsibilities

  • Build AI pipelines to ingest and process document knowledge bases (regulations, contract templates, legal frameworks) and generate structured rules and logic
  • Develop document understanding features: summarization, classification, party identification, payment terms, key dates, and required actions from uploaded PDFs
  • Implement document state analysis — execution status detection, document categorization, follow-up identification
  • Contribute across the deal intelligence stack: contract creation, e-signing workflows, payment triggers, file management, and compliance tracking
  • Work autonomously and communicate proactively — own features end-to-end

Required Tech Stack

  • Next.js / React — primary framework (frontend and API)
  • Python — basic understanding
  • Supabase — database and authentication
  • Vercel — deployment infrastructure
  • Claude API (Anthropic) — AI layer; strong prompt engineering skills required
  • TypeScript — used throughout the codebase
