Job description

The Role
You'll be the driving force behind our Avalonia-based desktop UI application, owning everything from architecture to the fine details of the user experience. This isn't a "make it functional" role, we want someone who loses sleep over fonts, colours and pixel alignment and gets excited about silky-smooth real-time interfaces.

- Create user interfaces optimised for low-latency, real-time data environments where responsiveness is critical.
Core Engineering
- Develop and maintain high-quality, performant C#/.NET ****application code.
- Implement robust MVVM patterns that keep our UI code clean and unit testable.
Collaboration
- Work closely with product, backend and wider design teams to translate requirements into polished, intuitive experiences.
- Contribute to technical decision-making and help shape the product roadmap.
Requirements
Do you have experience in Visual communication?, * Strong hands-on experience with Avalonia, WPF, or MAUI. You should know XAML inside out.
- A portfolio that demonstrates a genuine eye for visual design and UX quality.
- Solid cross-platform C#/.NET development experience (primarily .NET 5+).
