About The Position

We're building an AI-powered legal tech platform and need a backend-focused fullstack developer who treats AI tools as a core part of how they build — not an afterthought. You'll own features end-to-end across secure client portals and enterprise-grade B2B systems, from architecture to deployment. This is a high-trust, high-autonomy role on a small team where your decisions directly shape the product.

Requirements

  • 7+ years shipping fullstack TypeScript in production (React/Next.js and Node.js)
  • Proven ability to deliver complete features end-to-end with measurable business outcomes
  • Strong PostgreSQL or relational database design skills
  • Experience building production APIs with proper error handling, monitoring, and documentation
  • Hands-on cloud platform experience (GCP preferred; AWS or Azure acceptable)
  • Daily use of AI coding tools for the majority of your development work
  • Based in NYC and able to work in-office

Nice To Haves

  • Experience at a high-hiring-bar tech company or VC-backed startup (Seed–Series C)
  • Shipped a production AI feature: RAG, LLM integration, agents, embeddings, or semantic search
  • Currently working at a startup or growth-stage company under 1,000 employees

Responsibilities

  • Design and build scalable backend architectures for client and lawyer portals
  • Implement AI-powered workflows including document generation, case evaluation, and conversational interfaces
  • Build and maintain secure APIs in Node.js/TypeScript for internal and client-facing applications
  • Ensure systems meet compliance requirements for legal documents, client data, and financial transactions
  • Translate complex legal workflows into intuitive digital experiences alongside stakeholders
  • Use AI development tools (Cursor, Copilot, v0) as a primary part of your daily coding workflow
  • Own features from conception through deployment with measurable impact on user outcomes
