Robotics Software Engineer

Based in Barcelona, you will join a multidisciplinary team of electrical, controls, and software engineers building reliable, observable, and debuggable robotics systems. As the primary owner of firmware across our robotics platforms, you will operate at the boundary between hardware and software, guiding architecture decisions from concept through to validation and long-term maintenance. You will collaborate closely with hardware and software engineers, serving as the technical bridge that enables integrated, high-performing systems. Your work will directly shape the firmware foundations of our robotics platforms, with real scope to advise leadership on technical strategy and drive decisions that matter.

The day-to-day

• Design, implement, and maintain embedded firmware for real-time robotics systems, covering control, sensing, and system health monitoring across our hardware platforms
• Own the complete firmware lifecycle, from architecture and implementation through to testing, deployment, and ongoing maintenance, ensuring reliability and observability at every stage
• Diagnose and resolve complex system-level issues spanning firmware, software, hardware, and component behaviour, using tools such as oscilloscopes, logic analysers, and DMMs to identify root causes across timing, signalling, and electrical faults
• Serve as the technical bridge between hardware and software teams, collaborating with electrical, controls, motion planning, and systems engineers to deliver cohesive, high-performing robotics systems
• Advise leadership on firmware strategy and technical direction, shaping the evolution of our robotics platforms through technically rigorous, hands-on contribution

• Have built and shipped production-grade embedded firmware for real-time systems, with deep knowledge of MCU internals, peripherals, and real-time constraints
• Are proficient in C/C++ for embedded targets and have delivered projects involving communication protocols such as CANOpenFD, UART, I2C, or equivalent
• Have used hardware debugging tools, including oscilloscopes, logic analysers, and DMMs, to diagnose and resolve complex timing, signalling, and electrical issues
• Have taken full ownership of firmware end-to-end, from initial architecture through to validation and long-term maintenance, operating as the primary technical decision-maker
• Communicate fluently in both English and Spanish, enabling effective collaboration across a multilingual, multidisciplinary team Note: We operate in an industry where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don't meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.

Nice to Have

• Have experience with motor control, power stage firmware, or embedded communications in robotics or industrial automation environments
• Are familiar with supporting tooling such as Linux, Docker, or CI/CD pipelines (for example, GitHub Actions)

• Competitive salary and VSOP options
• Relocation support: up to €2,500 and 4 weeks temporary accommodation
• Learning: €500/£450 yearly allowance
• Health & wellness: gym membership and mental health support (Nilo.health)
• Social: regular company events and monthly social allowances
• Enhanced parental leave: 22 weeks fully paid for primary caregivers & 6 weeks for secondary caregivers
• Family support: 5 days of paid family emergency leave, 100% remote work option during pregnancy and phased return to work
• A hands-on onboarding program (affectionately labelled "Infraduction"), in which you will be building tooling and applications to be used across the company. This is your opportunity to learn our tech stack, explore the company, and learn how we get things done - all whilst working with other engineering teams from day one Helsing is an equal opportunities employer.

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., Join Helsing and work with world-leading experts in their fields + Helsing's work is important. You'll be directly contributing to the protection of democratic countries while balancing both ethical and geopolitical concerns + The work is unique. We operate in a domain that has highly unusual technical requirements and constraints, and where robustness, safety, and ethical considerations are vital. You will face unique Engineering and AI challenges that make a meaningful impact in the world + Our work frequently takes us right up to the state of the art in technical innovation, be it reinforcement learning, distributed systems, generative AI, or deployment infrastructure. The defence industry is entering the most exciting phase of the technological development curve. Advances in our field of world are not incremental: Helsing is part of, and often leading, historic leaps forward + In our domain, success is a matter of order-of-magnitude improvements and novel capabilities. This means we take bets, aim high, and focus on big opportunities. Despite being a relatively young company, Helsing has already been selected for multiple significant government contracts + We actively encourage healthy, proactive, and diverse debate internally about what we do and how we choose to do it. Teams and individual engineers are trusted (and encouraged) to practise responsible autonomy and critical thinking, and to focus on outcomes, not conformity. At Helsing you will have a say in how we (and you!) work, the opportunity to engage on what does and doesn't work, and to take ownership of aspects of our culture that you care deeply about
