Embedded Software Engineer

About the role

You will architect and develop safety-critical embedded software that directly powers General Matter's industrial enrichment systems with unwavering reliability and precision. Your code will command physical actuators and process high-speed sensor data where errors are not an option and safety is paramount. You will build low-level firmware in C, C++, Rust, and PLCs to orchestrate electromechanical hardware and execute fault-tolerant control logic. You will own the entire software lifecycle from development through deployment by creating automated build, test, and validation infrastructure. You will partner closely with hardware, electrical, and controls engineers to bring up new systems, integrate firmware with complex hardware, and troubleshoot intricate electromechanical challenges. You will perform rigorous safety analyses and validate control logic to guarantee deterministic behavior and functional safety under both nominal and fault conditions. You will debug real-world embedded systems using oscilloscopes, logic analyzers, protocol analyzers, and other laboratory instrumentation to root-cause elusive issues. You will contribute to integrated system testing, commissioning, and continuous improvement of embedded software running on production equipment to ensure operational excellence.
