About the role

Senior mechanical engineer based in Barcelona, responsible for mechanical architecture, design, and development of next-generation robotic systems. Owns electromechanical systems from concept through production and leads cross-functional collaboration with electrical and software teams to ensure robust, manufacturable platforms for European defence applications.

Responsibilities

  • 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 production ramp-up.

Qualifications

  • Have shipped complex robotic, mechatronic, or automated systems to market, with a verifiable track record of ownership across the full product development cycle.
  • Expert-level proficiency in 3D CAD modelling, ideally SolidWorks, combined with deep knowledge of GD&T for precision manufacturing environments.
  • Applied structural and thermal FEA, static simulations, and tolerance stack-up analysis to solve real engineering problems in production-grade systems.
  • Worked extensively across diverse manufacturing processes, including CNC machining, injection moulding, sheet metal fabrication, and additive manufacturing, in high-mix or low-to-medium volume environments.
  • Communicate complex technical decisions with clarity to cross-functional stakeholders, from firmware engineers to programme leadership, driving alignment without sacrificing rigour.
