Firmware Engineer

We're looking for a hands-on software engineer who wants to join us in building our core firmware from the ground up and define the future of our physical products.

📍 About the Role & Location

What you get: As a Firmware Engineer at Balder, you'll be at the heart of our innovation, developing the core embedded technology for our next-generation container tracking devices. In this key role, you will work in a green-field environment, taking significant ownership and making a direct impact on our physical product.

This role is primarily based at our Lysaker office in Oslo, where you'll join our team of hardware, firmware, and cloud engineers in a dynamic, hands-on environment. Your regular presence in the office is key to facilitating direct collaboration, hardware development, and fostering a solid team culture. Our Lysaker office provides dedicated lab space, essential for hardware development and debugging.

Your impact at Balder: This isn't just another firmware role. As one of our first developers (we started in 2025), you'll be stepping into a true green-field project. You won't be maintaining legacy code; you'll be creating it. We need a builder, a problem-solver, and a pioneer who is excited by the prospect of taking a product from a concept to a global reality. You will have a unique opportunity to lay the technical foundation of our core product. Your decisions will directly influence the performance, reliability, and scalability of our smart container solution.

🛠 What You Will Do

• Architect, develop, and maintain robust firmware for our asset tracking device on the Nordic Semiconductor platform.

• Take a leading role in the entire embedded software lifecycle, from initial concept and design to deployment and updates.

• Make key technical decisions that will shape the future of our hardware and software integration.

• Engage in hands-on testing, debugging, and validation of the physical product.

• Collaborate closely with the wider team to define product features and ensure seamless functionality.

🧠 Key Technical Challenges

• 🔋 Ultra-Long Battery Life: Develop power-efficient firmware that allows our sensors to operate for over 12 years without maintenance.

• 🛰️ Global Connectivity: Implement and optimize communication stacks for cellular (LTE-M/NB-IoT) and satellite networks to ensure seamless global tracking.

• 💡 Intelligent Sensing: Create logic to detect key events, from movement and door intrusion to environmental changes, in real-time.

• 🛡️ Rock-Solid Reliability: Build firmware that is robust enough to withstand the harshest conditions at sea and on land, with fail-safes and over-the-air update capabilities.

📋 Who You Are

• Strong programming experience with a good understanding of systems programming (C/C++/Rust).

• Experience with, or interest in learning, embedded programming, debugging, etc.

• Comfortable taking ownership and making decisions in a dynamic startup environment.

• Ability to work hands-on with hardware for development and debugging.

• Experience with the Nordic Semiconductor platform (nRF Connect SDK).

• Familiarity with Zephyr RTOS.

• A Bachelor's degree or higher in a relevant engineering field.

• A passion for solving complex problems in the logistics and IoT space.
