Job description

  • Zero to One: Take the product from MVP concept to Production.
  • Full Ownership: Build the core platform end-to-end (Backend, APIs, Frontend).
  • Architecture: Design for security, permissions, and scale from day one.
  • Speed: Iterate fast with real customers. The goal is to launch the API in Q2.

This is not a ticket-taking role at a stagnant SaaS. This is a Decide + Build + Own seat where you sit directly beside the founder.

Requirements

  • Experience: A Senior Engineer (Backend-leaning or Full-stack) who has shipped early-stage products into production.
  • Tech: Hands-on experience with LLMs & agentic workflows. You are pragmatic about tech choices that optimize for speed and correctness.
