- **Develop people:** Support and grow a team of 1–3 junior engineers, partnering with product managers to complete projects and develop talent in parallel
- **Startup agility and initiative:** Operate inside a small, scrappy team that punches above its weight — get stuff done, figure things out, and marshal the resources you need to hit the goal
- **Engineering quality:** Apply refactoring, careful data design, and disciplined testing (the team maintains a 1.4:1 test-to-code ratio) to keep the codebase healthy as it grows
- **AI-assisted development:** Use tools like Claude Code or Codex fluently as a force multiplier on already strong development practices, and know when to reach for which model

- **Creative problem-solver:** Enjoy evaluating and incorporating third-party software and APIs to move faster without cutting corners
