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
