• Design, develop, and maintain embedded software for ARM Cortex-M-based systems.

• Develop bare-metal and RTOS-based firmware using Embedded C.

• Implement and optimize drivers for peripherals including UART, SPI, I2C, GPIO, DMA, timers, and watchdogs.

• Design bootloaders, firmware update mechanisms, and low-power embedded applications.

• Develop and support wireless communication solutions, including Z-Wave, mesh networking, and proprietary sub-GHz protocols.

• Collaborate with hardware engineers to integrate firmware with embedded hardware platforms.

• Debug, troubleshoot, and validate embedded systems using J-Link, SWD, GDB, and other development tools.

• Contribute to secure firmware design, OTA updates, and product reliability.

• Participate in code reviews, documentation, and continuous improvement initiatives.

What We're Looking For

Required Qualifications

• Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field (or equivalent experience)

• Strong experience developing embedded software in Embedded C

• Experience with ARM Cortex-M microcontrollers and bare-metal and/or RTOS-based firmware

• Proficiency with interrupt-driven architectures and embedded peripherals (UART, SPI, I2C, GPIO, DMA, timers, watchdogs)

• Experience developing bootloaders, firmware update systems, and low-power embedded applications

• Experience debugging embedded systems using J-Link, SWD, GDB, or similar tools

• Strong communication skills with the ability to work independently and collaborate with hardware engineering teams

Preferred Qualifications

• Experience with Silicon Labs EFR32, Gecko SDK, Simplicity Studio, or Silicon Labs wireless stack APIs

• Hands-on experience with Z-Wave, proprietary sub-GHz protocols, mesh networking, or low-power wireless sensor networks

• Knowledge of secure boot, firmware signing, encrypted OTA updates, secure pairing, and embedded security best practices

• Experience with modular firmware architecture, state-machine design, Git, CI/CD pipelines, and automated testing

• Familiarity with RF concepts, including antenna performance, RF optimization, EMC/EMI troubleshooting, and wireless certification

• Experience supporting smart home, HVAC, industrial, or connected IoT products
