Senior Full-Stack Engineer
About this role
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
Must-Have Skills:
- 5+ years of full-stack experience; strong in React, Next.js App Router, and TypeScript (strict mode)
- Solid backend skills: RESTful API design, relational database modeling (PostgreSQL), and ORM usage (Drizzle or Prisma/TypeORM)
- Experience wiring up AI SDK or LangGraph — prompt engineering, tool/function calling, streaming responses
- Familiarity with async job patterns — queuing work, tracking state in a jobs table, handling retries
- Proficiency with Tailwind CSS and component libraries (Radix UI / shadcn/ui)
- Experience with cloud infra on AWS (S3, SES, RDS) or equivalent
Nice-to-Have:
- Multi-agent orchestration experience
- Graph database exposure (Neo4j)
- Terraform or infrastructure-as-code
- Vercel platform (feature flags, Edge Config, Fluid Compute)
- Python for data pipeline work
Stack:
Next.js 16 · TypeScript · Drizzle ORM · PostgreSQL · Neo4j · LangGraph · Anthropic Claude · Vercel AI SDK · AWS (S3 / SES / RDS) · Tailwind CSS · Recharts · React Force Graph · Vitest · Playwright · Vercel
