The role involves building, optimizing, and refactoring desktop applications, collaborating in an Agile environment, and leveraging AI tools to enhance productivity.

Location: Remote (Ukraine)

Responsibilities

• Architect and build high-performance features using .NET 10 and WPF, ensuring the UI remains fluid and responsive under heavy loads
• Develop and optimize C++/CLI wrappers to maintain a seamless, memory-safe bridge between our .NET environment and native C++ core libraries
• Profile and hunt down complex desktop issues - eliminate memory leaks, fix UI thread blockages, and resolve interop vulnerabilities
• Deliberately refactor legacy modules, gradually transforming older parts of the codebase into clean, testable, and modern architecture
• Conduct high-standard code reviews
• Leverage modern AI-assisted tools to accelerate routine coding, unit-test generation, and documentation
• Collaborate closely with the team during 2-week sprints to flesh out technical requirements, cover tricky corner cases, and estimate complex tasks.

Requirements

• 3-5+ years of commercial C#/.NET desktop development experience
• Deep WPF expertise: Strong mastery of MVVM, data binding, custom controls, and a solid grasp of the UI thread / Dispatcher model and async programming
• Real experience with .NET memory management and performance profiling - and a proven track record of fixing leaks, not just describing them
• Practical exposure to native C++ interop (C++/CLI, P/Invoke, or marshaling)
• Solid understanding of OOP, SOLID, clean code, and a genuine code-review habit
• Comfortable in Agile environment, writing clear acceptance criteria and handling corner cases
• A practical, daily relationship with AI-assisted development tooling (Copilot, Cursor, etc.) to boost productivity
• English strong enough to live in official documentation and deep-dive technical literature (MSDN, specs, deep-dive articles)

Benefits

• A chance to work with a strong team and a unique opportunity to make substantial contributions to our award-winning photo editing tools
• An educational allowance to ensure that your skills stay sharp
• English, German, and Polish classes to strengthen your capabilities and widen your knowledge
