About the role

About the Role

Join an early-stage team building AI software for enterprise procurement. You will own customer problems from discovery through production while helping shape the product, technical direction, and engineering practices.

What You'll Do

  • Build and ship full-stack features based on customer needs, from discovery through production.
  • Develop AI-enabled workflows and shared foundations for agent context, tool use, and evaluation.
  • Design reliable LLM workflows with evaluation loops, guardrails, and observability.
  • Make architectural decisions across performance, security, and developer experience.
  • Review AI-assisted code and improve product quality through frequent releases and user feedback.
  • Help establish engineering practices and contribute to hiring as the team grows.
  • Build real-time data pipelines and integrations with enterprise systems.

What We're Looking For

  • At least 3 years of full-stack engineering experience, delivering end-to-end product features across frontend, backend, and infrastructure.
  • Production experience with TypeScript and Python, plus hands-on experience building and deploying applications with Next.js.
  • Production experience with LLMs, retrieval systems, and embeddings, including an understanding of latency, cost, and quality trade-offs.
  • Strong frontend, backend, database, API design, and full-stack architecture skills; experience with React, PostgreSQL or Supabase, Vercel, and REST or GraphQL is relevant.
  • Evidence of strong engineering ability, initiative, and ownership, with experience shipping production software at a startup or similarly entrepreneurial team.
  • Experience with procurement, ERP, enterprise supply chain, or data-intensive B2B products is helpful.
  • Comfort working hands-on as an individual contributor, communicating clearly, and collaborating with a small team in person.
