Job description

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.

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. Integrate with on-chip and external interfaces including CAN, OBD-II, GNSS, cellular modems, and BLE.
• 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.

What's in it for you? At ABAX, we offer a growing and dynamic workspace with engaged and dedicated colleagues from all over the world. At ABAX, no two days are alike, and we offer a varied role with a lot of responsibility. With the right mindset, this role will challenge and allow you to keep developing your skills.
