Aristeem aristeem.com is an American IT company with Ukrainian roots that provides a unified service for running heavy software on any device for everyday users.
Aristeem is looking for a highly skilled Senior C++ Developer experienced in Windows graphics capture and real-time video processing. You will design, optimize, and maintain high-performance capture modules for screen and video pipelines, working closely with GPU APIs, hardware encoders, and complex multi-threaded systems.
Tech Stack
C++17/20, WinAPI, COM, DirectX 11/12, DXGI, WGC, D3D11on12, NVENC, AMF, QSV, Media Foundation, FFmpeg, ETW, PIX, RenderDoc, CMake, MSVC.
Responsibilities
* Develop and optimize image capture modules using DXGI Desktop Duplication API, Windows Graphics Capture, and fallback methods via GDI/DWM.
* Work with DirectX 11/12, shared textures, GPU—CPU synchronization, and zero-copy frame transfers.
* Implement cursor capture, HDR→SDR conversion, scaling, and color correction.
* Integrate with hardware encoders (NVENC, AMF, QSV) and media pipelines (Media Foundation, FFmpeg).
* Support multi-monitor setups, HiDPI, and virtual displays (IDD).
* Ensure optimal performance (≥120 FPS at 4K), resolving bottlenecks and thread race conditions.
* Develop internal SDK interfaces and logging tools (ETW/WPA).
* Participate in architectural discussions and code reviews.
Requirements
* 6+ years of professional experience in C++17/20 development.
* Deep understanding of WinAPI and COM.
* Proven experience with DirectX 11/12, DXGI, IDXGIOutputDuplication, and Windows Graphics Capture (WGC).
* Strong knowledge of multithreading, atomic operations, and GPU/CPU synchronization.
* Experience with Media Foundation, FFmpeg, or hardware video encoders (NVENC/AMF/QSV).
* Proficiency in profiling and debugging tools (ETW, PIX, RenderDoc, WPA).
* Understanding of WDDM, DWM, and Flip Model.
* Ability to write clean, efficient, and leak-free multi-threaded code.
Nice to Have
* Experience developing virtual displays or Indirect Display Drivers (IDD).
* Familiarity with zero-copy frame sharing (D3D shared handles, keyed mutex).
* SIMD optimization (SSE/AVX) for color space and format conversions (e.g., RGBA↔NV12, I420).
* Knowledge of OBS / obs-studio architecture or plugin development.
* Experience with streaming systems (WebRTC, RTSP, RTMP, HLS).
* Understanding of H.264/H.265 codecs, bitrates, and latency presets.
Personal Qualities
* Strong systems thinking and attention to low-level details.
* Commitment to quality, performance, and stability.
* Ability to justify technical decisions and collaborate effectively in a team.
We offer
