Senior UI Engineer - C++/C#/WPF (Windows) - Affinity

Join the team redefining how the world experiences design.

Where and how you can work:

The buzzing Canva London campus features several buildings around beautiful leafy Hoxton Square in Shoreditch. While our global headquarters is in Sydney, Australia, London is our HQ for Europe, with all kinds of teams based here, plus event spaces to gather our team and communities. You’ll experience a warm welcome from our Vibe team at front of house, amazing home cooked food from our Head Chef and a variety of workspaces to hang out with your team mates or get solo work done. That said, we trust our Canvanauts to choose the balance that empowers them and their team to achieve their goals and so you have choice in where and how you work.

What you’d be doing in this role:

• Build and maintain high-performance UIs in C++, WPF, and related frameworks
• Contribute to architecture and design decisions across shared libraries and components
• Optimise UI for responsiveness, scalability, and memory efficiency
• Debug, maintain, and improve complex systems across Affinity’s Windows suite
• Work closely with design and QA to deliver pixel-perfect, intuitive implementations
• Explore and integrate forward-looking frameworks (e.g., WinUI, MAUI) to future-proof Affinity apps
• Write clean, reliable, and well-documented code

You’re probably a match if:

• You have several years of experience in C++/C# development, with a strong focus on UI engineering
• You have proven experience with Windows frameworks (WPF essential, WinUI/MAUI desirable)
• You bring a strong understanding of object-oriented design and design patterns
• You have prior experience building professional desktop applications with high usability and performance standards
• You are familiar with graphics, imaging, or creative software (a plus)
• You are detail-oriented, with strong debugging and optimisation skills
• You are a clear communicator who enjoys collaboration and mentoring
