Firmware Engineer

About the Opportunity

Personal Connect is recruiting a Firmware Engineer

(Embedded Linux / SoC) on behalf of an innovative technology company operating

at the intersection of embedded systems, hardware-software integration, and

high-performance computing infrastructure.

The company develops advanced software and firmware

solutions for large-scale hardware deployments. Its technology combines

software-based monitoring and automated operations with low-level firmware

responsible for SoC and peripheral management, performance optimization, power

and thermal control, and hardware reliability.

This is a highly technical role focused on building and

optimizing the low-level software that powers embedded hardware platforms.

The successful candidate will take ownership of the

complete firmware lifecycle, including driver development, hardware bring-up,

firmware builds and releases, performance tuning, system services, and hardware

adaptation within embedded Linux environments.

The position is remote-friendly, with a preference for

candidates based in Beijing who can occasionally support on-site hardware

debugging and collaboration.
