Unfolding Your Next Role
We are looking for an experienced .NET WinForms Developer to join the frontend engineering team and help build high-performance, real-time trading applications used by professional traders.
This role is not about configuring UI frameworks – it is about crafting fast, responsive, custom-rendered desktop UI.
Tech & Tool Stack
C#
.Net
Your Daily Missions
- Design, implement and optimize custom WinForms controls (charts, grids, interactive visualization components).
- Work with continuous real-time data streams and ensure ultra-responsive UI under load.
- Ensure smooth multi-threaded UI updates without blocking or freezing.
- Collaborate with backend engineers (C++ systems) to maintain low-latency TCP/socket communication.
- Profile, debug, and tune rendering performance (GC pressure, paint cost, batching, flicker control).
- Improve engineering practices, and influence UI architecture and usability.
The Essentials We’re Seeking
- 5+ years of hands-on experience developing desktop applications in C#/.NET (preferably .NET 8).
- Strong expertise in Windows Forms.
- Proven experience building custom UI controls from scratch (inheriting from base controls and implementing custom rendering – not configuring DevExpress/Telerik/Infragistics).
- Experience working with continuous real-time data streams, where data is pushed to the UI (not periodic refresh).
- Strong understanding of multi-threaded UI applications (updating UI safely from worker threads, avoiding freezes and stalls).
- Practical experience in UI performance optimization (reducing redraw cost, minimizing GC pressure, batching updates, preventing flicker).
- Experience working with TCP / socket-based communication.
- Ability to clearly explain previous UI design decisions, trade-offs, and the impact on end users.
- Fluency in English (minimum B2+).
Nice-to-haves
- Experience with trading systems, market data, or real-time financial applications.
- Familiarity with C++ or interoperability between C# and native components.
- Understanding of high-performance visualization and data interaction patterns.
