Electrical Engineer Firmware

Bray•Houston, TX

About The Position

Provide technical leadership for the design, development, and delivery of new controls products, while sustaining and improving existing valve control and IoT products. The role develops and maintains embedded firmware, integrates firmware with hardware, and contributes to testing, optimization, documentation, and cross-functional engineering efforts. The position involves building real-time embedded applications in C/C++ for microcontrollers, working in bare-metal or RTOS environments, and implementing drivers for hardware peripherals and communication interfaces. It also includes debugging and validating firmware, participating in design and code reviews, and using version control, build systems, and CI pipelines. Bray describes a smoke-free, drug-free workplace and offers professional development and career advancement opportunities. Employment is contingent on successful background screening and compliance with applicable federal requirements, including drug testing for controlled substances under the federal Controlled Substances Act.
