We're seeking a Senior Firmware Engineer to join our team based in Costa Mesa, CA. As a Senior Firmware Engineer, you will contribute low-level firmware development for systems operating on land, sea, and air. You will develop low-level firmware/software for microcontrollers, create reusable device drivers, integrate system-level features, and architect changes to support an ever-growing codebase.

Key responsibilities include:

Design, implement, and optimize real-time applications within an RTOS environment, managing tasks, threads, and inter-process communication for deterministic system behavior.

Architect robust and fault-tolerant software using RTOS primitives such as mutexes, semaphores, message queues, and event flags to handle concurrency and resource sharing effectively.

Develop firmware in bare-metal or RTOS environments, with extensive experience with popular RTOS platforms (e.g., FreeRTOS, Zephyr, RTX, ThreadX).

Integrate microcontrollers with analog and digital sensors, and debug firmware using JTAG, SWD, Oscilloscopes, and Logic analyzers.

Requirements include:

Bachelor's or Master's degree in Computer Science, Electrical Engineering, or related field.

5+ years of experience in firmware/embedded software development, with a focus on embedded systems.

Strong C coding ability for embedded systems.

Experience integrating microcontrollers with analog and digital sensors.

Experience developing firmware in bare-metal or RTOS environments.

Extensive experience with popular RTOS platforms (e.g., FreeRTOS, Zephyr, RTX, ThreadX).

Solid understanding and application of coding best practices, board bring up, and debugging.

Preferred qualifications include:

Experience with one or more microcontroller cores (ARM, AVR, MSP430, PIC, etc.).

Bias for action, with a natural curiosity about the technologies and tools used.

Salary range: $191,000 - $253,000 USD.
