We’re looking for a skilled Firmware Engineer to join our growing team in Larvik, Norway. You’ll be part of a cross-functional team of six, including Product Managers, Hardware Engineers, and Software Engineers. While it’s a distributed team, most members are based in Norway, with additional colleagues in Sweden. Together, we work closely to develop and deliver cutting-edge telematics solutions. If you’re passionate about embedded systems and enjoy working in a collaborative, agile environment — we’d love to hear from you. Some of the things you will be working on: Firmware Delivery Develop and maintain embedded firmware in C for telematics hardware platforms. Optimize code for performance, memory usage, and power efficiency. Platform & Interfaces Work with traditional hardware interfaces such as I2C, UART, and SPI.

Security & Updates Implement and maintain secure bootloaders and OTA (over-the-air) update mechanisms. Develop robust firmware upgrade solutions. Debugging & Validation Debug and troubleshoot embedded systems using tools like oscilloscopes, logic analyzers, and software debuggers. Collaborate closely with hardware engineers on board bring-up and validation. We believe you bring: Proficiency in C programming for embedded systems. Experience with RTOS-based and bare-metal firmware development. Strong knowledge of microcontroller architectures, preferably ARM Cortex-M. Solid understanding of hardware interfaces: UART, SPI, I2C, CAN, ADC/DAC, GPIO. Knowledge of low-power design and energy-efficient firmware techniques. Proficient in using embedded debugging tools and test equipment. Experience with version control systems (e.g., Git) and CI/CD pipelines for firmware development. Awareness of embedded security best practices (e.g., secure boot, encryption). Experience with AI-assisted development tools (e.g., code generation, debugging, and optimization), and the ability to use them effectively in firmware development workflows. Nice-To-Have: Familiarity with Zephyr and cross-compilation toolchains. Understanding of GNSS and cellular communication protocols. A degree in Computer Science, Hardware Engineering, or a related field. Not ticking every box? That’s okay — we know that great candidates don’t always check off every single requirement.
