Job description

We are building a data-intensive M&A deal-tracking platform - a web application where investment bankers manage pipelines, process documents, and surface AI-driven insights. We're looking for a Senior Full-Stack Engineer who is equally comfortable shipping polished React UIs and designing backend systems that handle document ingestion, async job pipelines, and AI agent orchestration.

Key Responsibilities

• Build & maintain the full stack - from Next.js App Router pages and API routes through to the PostgreSQL schema, Drizzle migrations, and background job workers
• Own AI-powered features - integrate and extend LangGraph agents (document classification, structured extraction, company enrichment) using the Anthropic SDK and Vercel AI SDK
• Design backend systems - model new domain concepts in Drizzle ORM, write service and repository layers following clean architecture, and queue async work through the jobs table
• Drive quality - write unit tests (Vitest) and Playwright e2e tests for every feature; participate in code reviews
• Collaborate across functions - translate business requirements from the deal team into technical specs, and work with product on iterative feature releases gated behind feature flags
