About the job

Goods & Services is looking for a Senior 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:

• 5+ 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
