Who we are

Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards.

As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously.

We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.

The role

We are looking for an experienced and passionate firmware engineer with a hands-on and problem-solving mindset to join us at our office in Barcelona. You will work on solving real challenges in a fast-paced environment,



working closely with a multidisciplinary team of electrical, controls, and higher-level software engineers to build reliable, observable, and debuggable robotics systems.

You will operate at the boundary between hardware and software, with a strong electrical engineering mindset, helping to architect the future of robotics through best-in-class, modern software engineering practices.

This is an individual contributor role. You will be the main owner of the firmware across our robotics platforms — from concept through implementation, validation, and long-term maintenance. It is not a management position, and we're looking for someone who thrives working autonomously and taking end-to-end technical ownership, while collaborating closely with the wider hardware and software teams.

Day-to-day
- Design, implement, and maintain embedded firmware for real-time systems: control, sensing, and system monitoring
- Own the full firmware
