We are seeking a hands-on Firmware Manager to lead and contribute to the development of embedded firmware for our wireless, RF-enabled, and IoT products. In this “player-coach” role, you will guide a small team of engineers while remaining actively involved in coding, board bring-up, debugging, and optimization on ARM-based platforms. Our ideal candidate brings deep expertise in BLE, LoRa/LoRaWAN, cellular technologies, RF systems, and sensor integration — delivering reliable, low-power embedded solutions from concept through production.

Lead and mentor a small team of firmware engineers while contributing directly to development.
Design, implement, and optimize firmware in C/C++ for bare-metal and RTOS environments on ARM microcontrollers and processors.
Drive hardware bring-up and system initialization for boards integrating RF, BLE, LoRa/LoRaWAN, cellular, and sensor subsystems.
Configure and manage communication interfaces including UART, I2C, SPI, USB, and Ethernet.
Integrate and optimize wireless features including BLE, LoRa/LoRaWAN, LTE, LTE-M/NB-IoT, and GPS/GNSS.
Perform power profiling and optimize firmware for battery-powered, ultra low-power devices.
Collaborate with hardware, RF, and manufacturing teams to troubleshoot and optimize system performance.
Use lab equipment such as oscilloscopes, logic analyzers, spectrum analyzers, and protocol analyzers for system validation and debugging.
Ensure adherence to firmware development best practices including testing, documentation, debugging, and code reviews.

7–10 years of professional embedded firmware development experience, with at least 2–3 years in a leadership or mentorship role.
Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field (Master’s preferred).
Experience with IoT systems and wireless/wired communication protocols including BLE, LoRa, LoRaWAN is mandatory.
Expertise in developing firmware on low-level embedded systems, ARM core-based microcontrollers and processors; experience with Nordic devices is mandatory.
Hands-on experience of radio cellular protocols (LTE, LTE-M, NB-IoT) and industrial wireless devices.
Experience working with cellular modems and GPS/GNSS systems.
Experience developing firmware to interface various sensors and communication modems.
Proven experience in developing low-power embedded devices, including performing firmware power profiling.
Knowledge of PCB design and schematic/layout tools (Eagle / Altium preferred).
Strong debugging skills at the hardware/firmware boundary with the ability to read complex schematics.

Work on cutting-edge RF, wireless, and IoT products with a passionate, multidisciplinary team.
Balance leadership with hands-on technical contributions.
Impact the full product lifecycle — from concept to production.
