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

Your work will be central to solving some of the most interesting challenges in IoT and logistics:

🔋 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.

Nice to have:

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.
