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.
 

At AlphaDevs

We don’t just build remote teams - we build long-term engineering partnerships.
We work with product companies that value stability, quality, and sustainable technical evolution - 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 — most of the team is Ukrainian, and daily communication happens in Ukrainian.

• Has been developed and evolved over many years
• Contains complex business logic, data flows, and integrations
• Is mission-critical for daily operations
• Is planned for gradual migration from Delphi to modern .NET (C#) architecture

This is not a greenfield project - it’s real engineering on a real system with real impact.

• Learn to understand a legacy Delphi codebase with the support of senior engineers

• Participate in the gradual migration from Delphi to .NET (C#)
• Work with MSSQL databases and business data models
• Write clear code and basic technical documentation

What You Bring

• 2+ years of commercial experience with C# / .NET
• Basic understanding of OOP and software design principles
• Basic knowledge of Delphi or strong motivation to learn it
• Experience working with SQL databases (MSSQL is a plus)
• Willingness to work with legacy code and learn complex business logic
• Responsibility, curiosity, and desire to grow as an engineer
   

Nice to Have

• Experience with ERP, CRM, or other business systems
