Principal C# Backend Engineer
goodsservices
If you want to work on backend systems that matter from the start of your career, this role gives you real ownership. You'll be building workflow orchestration and state management for mission-critical platforms used by large enterprises in regulated industries like life sciences and financial services. That's meaningful work, not busywork.
Your day-to-day: develop and maintain analyzer workflow logic within the ECL platform, owning backend processes end-to-end. You'll implement workflow orchestration, extend analyzer integrations, and deliver scalable, event-driven solutions. This means you'll spend time modernizing legacy systems and building reliable, production-grade code—the kind of experience that compounds fast.
You should have solid C# fundamentals and a real interest in backend design patterns. A portfolio with backend projects, coursework in software architecture, or internship experience counts. You don't need years of experience; you need curiosity and the ability to learn on the job.
