Project – the aim you’ll have

You will join an agile, international team of experienced developers and testers (Poland/UK) working on a strategic transformation of the IT ecosystem for a leading travel industry company. The main goal is designing and building modern, scalable solutions from scratch to replace outdated systems using best engineering practices.

Position – how you’ll contribute

We are looking for a growth-oriented intern or junior .NET developer who already has solid C# basics and genuinely wants to learn.

Your daily tasks will include:

• Developing backend tasks in .NET, maintaining APIs, and assisting with system integrations
• Writing clean, testable code and creating unit tests with mentor support
• Utilizing AI tools consciously for code generation, refactoring, debugging, and technical research
• Participating in code reviews, internal workshops, technical demos, and analyzing bugs/logs
• Collaborating closely with experienced developers and verifying AI-generated solutions before implementation
