Junior C# / .NET Developer (with basic Delphi knowledge)

Ever wanted to grow as an engineer on a real product - not pet projects or short-term tasks, but a system that real businesses rely on every day?
Where you don’t just “code features”, but gradually learn how large, mission-critical systems are built, maintained, and modernized?
Where you can gain hands-on experience with legacy systems and be part of a long-term transition to modern .NET architecture?
If you’re a Junior/Middle- level C# developer with around 2 years of experience and curiosity about real-world systems - this role is a great growth opportunity.

Has been developed and evolved over many years
