On behalf of our client, we are looking for a C# / WPF UI Developer

About the Role:
You will join a small, fully remote engineering team to develop high-performance desktop interfaces that help traders and portfolio managers monitor market data, manage positions, execute trades, and analyze trading activity in real time.

- Improve and extend existing trading tools as the platform expands into new markets and exchanges.
- Troubleshoot, optimize, and maintain existing desktop application functionality.

- Ability to independently design and implement UI features without a dedicated UI/UX designer.
- Good understanding of UI performance optimization, responsiveness, and efficient data presentation.
- Experience integrating desktop applications with APIs, backend services, or continuously updating data sources.
- Strong problem-solving skills and ability to work independently in a small engineering team.

- Familiarity with financial markets, exchanges, or trading workflows.
- Experience with statistical modeling, signal processing, or quantitative systems.
