- Build low-level firmware components including device drivers, initialization and startup code, timing-sensitive system software, and radio control features.
- Optimize embedded software for performance, reliability, power efficiency, and memory and CPU utilization.
- Debug complex issues across software, firmware, hardware, and system boundaries using lab tools and debuggers.
- Collaborate with hardware, silicon, systems, and product teams on requirements, design reviews, and new-device bring-up.
- Contribute to automated testing, validation, and development tooling.
- Participate in code and design reviews and provide technical guidance and mentorship to other engineers.
Requirements
- Bachelor’s or master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent practical experience.
- At least 5 years of professional embedded software or firmware development experience.
- Strong programming skills in Embedded C and/or C++.
- Experience developing microcontroller software in resource-constrained, real-time environments using bare metal and/or RTOS-based systems.
- Hands-on hardware/software debugging experience with debuggers, JTAG/SWD, oscilloscopes, or logic analyzers.
- Experience with low-level embedded software such as device drivers, interrupts, peripheral interfaces, timing-sensitive code, or memory-constrained systems.
- Experience taking features from design through implementation, testing, and release.
- Strong problem-solving, communication, and collaboration skills.
- Preferred experience includes Bluetooth LE, Zigbee, Thread, Wi-Fi, proprietary radio systems, communication stacks, radio control software, PHY/MAC functionality, low-power optimization, SPI, I2C, UART, DMA, timers, automated testing, CI, validation frameworks, hardware-in-the-loop testing, silicon bring-up, multicore microcontrollers, concurrency, synchronization, shared-resource challenges, and ARM or RISC-V assembly.
- Preferred experience also includes Python or similar scripting languages and AI-assisted development tools such as GitHub Copilot, Cursor, and ChatGPT.
