About the job

Goods & Services is looking for a  Principal C# Backend Engineer with expertise in workflow orchestration, state management, and backend service design. Experienced in modernizing legacy systems, building reliable analyzer integrations, and delivering scalable, event-driven solutions.
Location:  Loveland, Colorado.

What you’ll do:

  • Develop and maintain analyzer workflow logic within the ECL platform, owning the backend processes that drive analyzer operations end-to-end
  • Implement and extend workflow orchestration — managing analyzer state transitions, operational sequencing, and runtime event handling
  • Collaborate with the Analyzer Integration Engineer on the communication layer between ECL and connected analyzers
  • Support the DCU modernization effort by identifying workflow logic that can be extracted and repackaged into shared .NET libraries
  • Work with QA to ensure workflow correctness and reliability across analyzer types and edge cases
  • Participate in knowledge transfer from departing Hydra resources to preserve continuity of analyzer workflow behavior.

What you’ll need:

  • 7+ years of professional C# / .NET backend development experience
  • Experience building workflow or orchestration systems — state machines, process sequencing, or similar patterns
  • Solid understanding of backend service design and inter-service communication
  • Ability to work within and around legacy codebases without breaking production.
  • Collaborative approach to working alongside integration and infrastructure engineers.

Nice to have:

  • Exposure to medical device, laboratory, or instrument integration workflows
  • Familiarity with .NET Framework 4.x and modern .NET migration patterns
  • Experience with Azure Service Bus or event-driven messaging
  • Background picking up ownership of an inherited or underdocumented system
