Essential
- 5+ years professional software development experience
- Proven experience working on live production systems
- Full-stack JavaScript / TypeScript (Next.js, Node, APIs, databases)
- Python experience (scripting, services, tooling, data processing)
- Strong refactoring and system-improvement skills
- Comfortable in fast-moving, imperfect environments
- Able to work autonomously with strong judgement on priorities & risk
Highly Desirable
- C# / .NET experience
- Startup or scale-up background
- Technical leadership experience
- Experience across multiple internal products
