• Design and maintain bootloaders and firmware update mechanisms.
• Support secure and wireless OTA firmware updates.
• Debug embedded systems using tools such as J-Link, SWD, and GDB.
• Develop low-power firmware solutions for battery-powered and connected devices.
• Design and support wireless communication, mesh networking, and low-power sensor networks.
• Work with RF and hardware engineers to troubleshoot system-level issues.
• Support firmware architecture, state machines, event-driven systems, and hardware abstraction layers.
• Participate in code reviews, testing, CI/CD, and firmware documentation.
• Support product security through secure boot, firmware signing, key provisioning, encrypted communications, and secure credential storage.
• Assist with debugging, RF performance optimization, EMC/EMI troubleshooting, and certification activities as needed.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field.
• Strong hands-on experience with Embedded C.
• Experience developing bare-metal and/or RTOS-based firmware.
• Strong experience with ARM Cortex-M microcontrollers.

• Hands-on experience with common embedded interfaces including UART, SPI, I2C, GPIO, DMA, timers, and watchdogs.
• Experience with embedded debugging tools and techniques.
• Experience with bootloaders and firmware update systems.
• Understanding of low-power embedded system design.
• Experience with wireless communication protocols and connected devices.
• Strong troubleshooting and problem-solving skills.
• Ability to work independently and collaborate effectively with hardware and engineering teams.

Preferred Qualifications

• Experience with Z-Wave, proprietary sub-GHz protocols, mesh networking, or low-power wireless sensor networks.
• Experience with wireless OTA firmware updates and RF coexistence.
• Experience with Silicon Labs wireless platforms, SDKs, or development tools.
• Experience with custom protocol development or MAC/PHY-level modifications.
• Knowledge of secure boot, firmware signing, encrypted OTA updates, secure pairing, authentication, and replay protection.
• Experience with modular firmware architecture and event-driven design.
• Experience using Git, CI/CD pipelines, automated testing, and hardware abstraction layers.
• RF knowledge, including antenna and layout considerations, RF sensitivity, link budgets, sub-GHz propagation, and EMC/EMI troubleshooting.
• Familiarity with spectrum analyzers, VNAs, or other RF test equipment.
• Experience supporting products in smart home, HVAC, industrial, IoT, access control, or infrastructure environments.
