Who We Are Helsing is a defence AI company. As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.
Based in Barcelona, this role sits at the heart of Helsing's robotics engineering function, responsible for driving the mechanical architecture, design, and development of next-generation robotic systems. You will own complex electromechanical systems from concept through to production, ensuring platforms are robust, scalable, and built for real-world deployment. Working closely with electrical, firmware, and software engineers, you will bring both technical depth and cross-functional leadership to a team building some of the most consequential technology in European defence.
Lead the detailed design and integration of complex robotic subsystems, including high-precision actuators, structural chassis, and dynamic motion systems,



translating high-level concepts into robust 3D assemblies and comprehensive engineering drawing packages.
Drive cross-functional integration with electrical and software teams to ensure seamless packaging, cable routing, and thermal and sensor integration, resolving technical challenges across the full development cycle.
Define material selection strategies and fabrication methods, conducting FEA, stress analysis, and tolerance stack-up analysis to ensure designs meet rigorous functional, cost, yield, and lead-time requirements.
Establish and advocate for mechanical engineering best practices, including modelling standards, GD&T; drawing controls, and technical documentation, raising quality across the team.
Critically evaluate system architectures in design reviews, identifying risks and delivering high-impact solutions that optimise performance and manufacturability from prototype through to productio
