Senior Delphi / .NET Developer (C#, .NET, Azure)

Ever wanted to be the engineer who modernizes the core of a real business?

Not just building features - but transforming a mission-critical ERP system that runs real operations, real money, and real workflows every day?

Where your code isn’t a side experiment, but the backbone of how a company operates?

Where you don’t rewrite for the sake of rewriting - but lead a thoughtful, long-term migration from legacy Delphi to modern .NET architecture?

If you enjoy deep systems, complex business logic, and long-term ownership of a large product - this role is built for you.

At AlphaDevs

We are committed to supporting Ukraine 🇺🇦 and are hiring Ukrainian engineers only for this role.

No strong English is required - 90% of the team is Ukrainian, and daily communication happens in Ukrainian.
