We are ITSG - a boutique software house where engineering excellence meets creative problem-solving. Unlike typical corporate environments, we’re a tight-knit team of technical craftspeople who approach each project as a unique engineering challenge. Our developers don’t just write code - they architect solutions that push the boundaries of what’s possible with modern technology. Working with select clients across Switzerland, Germany, USA, UK, and Poland, we take on sophisticated digital initiatives that require deep technical expertise. From distributed systems to innovative mobile solutions and AI features - we focus on challenges that make developers genuinely excited about their work. Right now, we’re looking for a Senior .NET Developer to join our team and take ownership of an ambitious mobile-first project. You’ll be working with .NET MAUI and sophisticated backend services, building a next-generation virtual card system that will serve thousands of users. This isn’t just another CRUD application - it’s a chance to architect and implement complex business logic, optimize performance at scale, and work with modern cloud infrastructure.
