About the job

Write the code that powers a smarter global supply chain.

We're expanding our firmware team and looking for a motivated Firmware Engineer. You will be instrumental in developing the core logic for our next-generation container sensors, which are cutting-edge IoT devices designed to track containers worldwide using cellular and satellite communication. These incredibly low-power devices operate for over 12 years on primary cell batteries, requiring no charging or service – making them truly unattended in the field. You'll be working in a fast-paced environment where you'll have significant ownership over your projects. This is a chance to build tangible products that have a real-world impact on global logistics.

• Design, develop, and maintain firmware for our low-power, long-life embedded IoT devices.

• Optimize firmware for ultra-low power consumption to meet our industry-leading battery life targets.

• Collaborate directly with hardware engineers on board bring-up, validation, and debugging.

• Develop and maintain robust test suites and automated testing infrastructure for firmware validation.

• Troubleshoot and resolve complex issues that span the hardware, firmware, and cloud interface.

What You'll Be Building

From Code to Container

As a Firmware Engineer at Balder, you're not just writing code; you're creating the intelligence that powers our global network of smart containers.
