Requirements
  • You are autonomous. There is no ticket queue, no hand-holding. You pick up the work, figure out what needs to be done, and do it.
  • You must be AI-fluent. Claude Code or Cursor should be your default. You use AI to punch above your weight, not as a crutch.
  • You must be pragmatic. Lunon is a startup so something is always on fire. Some things will be broken, some things will be unclear, and some things will change overnight. You figure it out and keep going.
  • You must be gritty. You pick the hardest, highest-quality option regardless of the effort it takes and you push through it.
  • Prior startup experience is strongly preferred.
  • Your GitHub should tell a story. We are not expecting dozens of polished repos, but we want to see someone who lives in code — consistent activity, real projects, and enough experience that branches, PRs, and merge conflicts are second nature.
Responsibilities
  • Own features end to end and ship them to real clients, seeing the impact immediately.
  • Work on the platform powering client engagements, from initial scoping through live AI-driven research and analysis to polished reports and deliverables that clients access directly.
  • Ship features yourself with no handoffs and no waiting on someone to unblock you.
  • Stay on top of the best tools as they emerge and bring that to the team.
  • Solve problems when you hit a wall and find a way through it.

Lunon provides a unified API for integrating large language models into applications. Developers connect once and can test, compare, and swap models in real time with a built‑in console, without changing or redeploying their code, while Lunon routes requests to optimize performance and cost. It charges a pay‑per‑request rate of $0.001 and offers flexible billing options, handling backend infrastructure so teams can focus on shipping features. Its goal is to simplify adding and managing AI capabilities in apps by centralizing model selection, routing, and cost control.
