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 don’t just build remote teams — we build long-term engineering partnerships.
We work with product companies that care about stability, quality, and long-term evolution of their systems — not quick fixes.

This role is part of a long-term product engagement focused on maintaining and gradually modernizing a large ERP platform used in real business operations.

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.
