Offer description

About Us
We're building the next generation of creative control and monitoring software. A platform that makes complex professional equipment and systems feel intuitive to everyone, from experienced professionals to first-time users.
We care deeply about craft. Every interaction, transition, and layout decision matters to us, and we're looking for a developer who feels the same way.
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.
The role is open to hybrid remote working, candidates should have the ability to commute to the office in London, WC2R 1EA.
Responsibilities
*UI Architecture & Design*
* Design and own the look and feel of our application and maintain consistant high standards.
* Design and maintain flexible UI controls suitable for usage in a variety of contexts (desktop, touchscreen, hardware button panels).
* 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.
What We're Looking For
* 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+).
* Proven experience building *MVVM* style desktop applications.
Useful Experience
* A background in entertainment lighting, video/AV or sound technology.
* Graphic design skills and experience with Adobe Illustrator or similar vector-based tools.
Why Join Us?
* Join a founding engineering team. Your decisions will shape the product from the ground up.
* Work on genuinely interesting, technically demanding problems for high-profile clients at the intersection of creative tooling and real-time systems.
* Competitive benefits
Job Type: Full-time
Pay: £60,000.00-£70,000.00 per year
Benefits:
* Company events
* Private medical insurance
* Sick pay
* Work from home
Language:
