Podsumowanie oferty

You will join the frontend engineering team to build high-performance, real-time trading applications for professional traders. The role focuses on custom-rendered desktop UI and responsive components using .NET, WinForms, and C#.

Wymagania

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 rather than configuring DevExpress, Telerik, or Infragistics.
Experience working with continuous real-time data streams pushed to the UI rather than periodically refreshed.
Strong understanding of multi-threaded UI applications, including safely updating the UI from worker threads and avoiding freezes and stalls.
Practical experience in UI performance optimization, including reducing redraw cost, minimizing GC pressure, batching updates, and preventing flicker.
Experience working with TCP/socket-based communication.
Ability to clearly explain previous UI design decisions, trade-offs, and their impact on end users.
Fluency in English (minimum B2+).

Nice to have:

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.

Obowiązki

Design, implement, and optimize custom WinForms controls, including charts, grids, and interactive visualization components.
Work with continuous real-time data streams and ensure an ultra-responsive UI under load.
Ensure smooth multi-threaded UI updates without blocking or freezing.
Collaborate with backend engineers working on C++ systems to maintain low-latency TCP/socket communication.
Profile, debug, and tune rendering performance, including GC pressure, paint cost, batching, and flicker control.
Improve engineering practices and influence UI architecture and usability.

Benefity

TechTalks, meet-ups, and guilds for knowledge exchange.
Flexible working hours, with the option to start between 7:00 and 10:00 am.
Bonuses for employee referrals, from 3000 PLN to 7000 PLN.
