If you're a deeply senior C# engineer who wants to actually build something new, not maintain legacy, not refactor someone else's mess, this is one of the few roles in the market worth stopping for. You'll be the technical spearhead for a greenfield SaaS platform, reporting directly to the Director of Engineering and shaping everything from architecture to AI-native delivery patterns. This is high-autonomy, high-impact work for someone who thrives in ambiguity and loves solving hard problems at pace.

Why this role stands out:

  • You set the engineering bar, not follow it.
  • You get to embed agentic AI workflows into real production systems.
  • You own outcomes end-to-end, not just tickets.
  • You influence product direction without layers of process or ceremony.

What You'll Bring:

  • Senior/Staff-level backend depth in C# and .NET 8/9.
