About The Position

Credigy's IT team is looking for a Senior .NET Developer to help modernize how we build and deliver enterprise software. You'll design cloud-native solutions in Azure, shape how our applications look and feel, and work directly with the people who use what you build. This is a high-visibility role in a fast-moving, entrepreneurial environment — ideal for someone who's curious about new tools, bold enough to challenge legacy patterns, and supportive of the teammates building alongside them. As a Senior .NET Developer, you'll work closely with end users, Product Owners, and Business Analysts to turn real business needs into automated solutions that cut costs and boost productivity. You'll build across the full stack — from React front ends to Azure-based backend services — and take ownership of both new development and the modernization of legacy .NET applications. You'll collaborate daily with QA Engineers, Architects, and business stakeholders, and your voice will carry weight in architecture and technical design discussions. Success in this role looks like shipping reliable, well-architected software with urgency, while helping the team around you get better along the way.
