Optical imaging software and game development tools for hardware integration
Topjoy is a 46-person engineering firm in Beijing building specialized software for optical microscopy systems and game development tooling. The stack—C++, Qt, FPGA, Python, and optical-design software (Zemax)—reflects deep hardware integration work, not generic IT services. Minimal hiring velocity and a mid-level engineering-heavy mix suggest a stable, project-focused operation rather than rapid scaling.
Topjoy develops custom software for optical imaging hardware (confocal microscope systems) and game development tools. The company operates as an engineering services and product shop, with active projects spanning image acquisition, confocal imaging software, and commercialization analysis. The technology stack emphasizes low-level systems work (C++, Qt, FPGA, TCP/UDP) paired with optical engineering (Zemax), indicating deep technical partnerships with hardware manufacturers. Based in Beijing, the company hires primarily across China.
C++, Qt, Python, FPGA, Zemax, SQL, R, Stata, plus Android and iOS for client-facing work. The mix reflects hardware-software integration and optical systems engineering.
Active projects include confocal imaging software, image acquisition systems, optical microscope standardization, game development tools, and market/commercialization analysis work.
