What you will do

• Develop high-performance bare-metal C/C++ firmware for resource-constrained microcontrollers powering RF front-end boards.
• Bring up custom hardware, clocks, peripherals, and drivers, including I2C, SPI, CAN, GPIO, UART, and Ethernet interfaces.
• Configure and control RF and microwave components such as DDS, PLL, LNA, PA, filters, and switches.
• Design lab tests and use oscilloscopes, spectrum analyzers, signal generators, and logic analyzers to verify RF performance.
• Develop firmware-based RF calibration techniques and Python automation for factory measurement and calibration processes.
• Own firmware reliability, validation, documentation, issue resolution, and project planning across the full development lifecycle.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, Software Engineering, or a related field.
• 5+ years of experience developing embedded firmware for RF/microwave front-ends in radar, RF seeker, wireless radio, or similar products.
• Proficiency in bare-metal C/C++ and experience optimizing deterministic, real-time software for memory-constrained environments.
• Deep knowledge of RF/microwave transmitter and receiver architectures, components, and calibration techniques.
• Hands-on experience with MCU bring-up, electronics schematics, communication protocols, lab equipment, functional testing, and software validation.
• Must be authorized to work in the United States and able to work 100% on-site in Huntington Beach, California. Access to export-controlled information may require authorization under U.S. export control laws without sponsorship for an export license.

Nice to have

• Strong theoretical background in radar, electromagnetic wave propagation, wireless communication, RF sensing, and RF calibration.
