At Voltrac, we’re on a mission to strengthen Europe’s food security and defence with a modular platform. The platform has been developed and is currently being tested at vineyards such as Bodegas Nodus.

We operate in a fast-paced, R&D-driven environment. We're currently building our foundational team, with a focus on autonomy, rapid iteration, and impactful engineering. You'll work closely with the leadership team and contribute to every stage of product development: from understanding end-user needs through to prototyping, manufacturing, and scaling for market adoption. Within 12 months, the aim is to evolve from prototype to the first serial production-ready vehicle.

If you're driven by curiosity, thrive in tackling hard engineering problems, and are motivated by building real-world impact with a team of sharp, mission-driven peers – this role could be a great fit.

You'll take ownership of projects from concept to production – including hands-on prototyping, detailed design, and rigorous testing. The role spans a broad range of responsibilities and requires close collaboration with teams across R&D, manufacturing, and QA. More specifically, you will:

• Use CAD, FEA, and engineering calculations to develop robust mechanical designs


• Perform analysis and testing to validate and optimise system performance


• Interface with suppliers and manage procurement for prototyping and production


• Work in close collaboration with electronics, mechatronics, and software teams to bring prototypes to life


• Lead field testing and iteration of functional prototypes


• Optimise tools, processes, and designs for serial production

• Degree in Mechanical or Aerospace Engineering (or equivalent practical experience)


• Demonstrated experience in hardware development, with a track record of taking designs from idea to reality


• Strong problem-solving and analytical skills with a hands-on, pragmatic mindset


• Clear communicator with collaborative instincts, especially in multidisciplinary environments
