  • Secondary oversight: Audiofy & RoutePortal
  • Review code and raise engineering standards
  • Partner closely with the CEO, product, and operations teams
  • Turn business problems into practical technical solutions
  • What We’re Looking For

    • Essential
    • 5+ years professional software development experience
    • Proven experience working on live production systems
    • Full-stack JavaScript / TypeScript, 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
