Lead cross-functional technical discussions to drive firmware architectural decisions and align implementation choices with system performance, reliability, and scalability goals.
Define, implement, and maintain well-specified interfaces between firmware, hardware, and higher-level software, including low-level drivers, communication protocols, and python APIs.
Design, implement, and validate embedded firmware across bare-metal, RTOS, and embedded Linux environments, including device drivers, closed-loop control algorithms, calibration routines, and deterministic state machines.
Partner closely with controls, hardware, systems, and test engineers to integrate firmware into complex systems and ensure correct end-to-end behavior under nominal and fault conditions.
Familiarity with build systems, version control, and test driven development.

Bachelor's or Master's degree in Computer Science, Electrical Engineering, or related field.
Minimum of 10 years hand-on firmware development and architecture experience leading to a successful commercial product.
