I’m leading the build-out of a next-generation multi-asset trading platform and need a senior engineer to own the desktop client. The entire UI layer is written in Avalonia on .NET 8, so expert-level C# and Avalonia skills are an absolute must. You should already have extensive experience in both WPF and Avalonia and a track record of delivering professional-grade desktop applications with rich, modern UI/UX. Beyond raw coding talent, I’m looking for someone who understands the pulse of the markets. Order books, level-II data, latency budgets, real-time charting and performance optimisation must be familiar territory; that domain knowledge will inform many architectural decisions we make together. Key deliverables • Implement high-performance market-data grid, depth chart and multi-chart workspace in Avalonia • Produce profiling reports that prove sub-50 ms UI updates while ingesting 10 k+ messages per second • Commit clean, test-covered C# code to our GitHub repo with CI passing • Supply concise architectural notes so other engineers can extend your work Nice-to-have experience with FIX gateways, broker APIs, or other cross-platform desktop frameworks will help you ramp up even faster, but the core requirement remains crystal clear: solid Avalonia mastery paired with real trading knowledge. Expect rapid iterations—daily Slack check-ins, GitHub PR reviews and short milestones. If that rhythm suits you and the mandate excites you, send over links to the professional desktop apps you’ve shipped, especially those showcasing complex UI or performance wins.
