About the team

You’ll join the Platforms team. We build new features on top of the image-processing core, work on performance, and integrate with new OS capabilities.

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).

Nice to have

• Experience with Image/graphics processing, GPU, or DirectX/Direct2D;
• Experience with WinUI 3;
• A background in photo, creative, or media desktop apps;
• Comfort improving large legacy codebases through deliberate and safe refactoring;
• Native instinct for desktop pitfalls — handling leaks, permission levels, and UI-thread affinity;
• Photography as a hobby.
