Senior Mechanical / Aerospace Engineer

At Voltrac, we are on a mission to strengthen Europe’s food security and defence with an autonomous electric tractor to free farmers from drudgery and keep soldiers out of harm’s way. The 3.5 tonnes platform is currently being tested at vineyards, olive orchards and citrus groves across Spain - check out our website to see it in action. We are about to scale manufacturing to 100 units yearly, and are looking to match the sales accordingly. As part of this scaling efforts, we are looking to strengthen our engineering team. You'll work closely with the founders 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 first customer delivery to regular production. 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. Who we are Voltrac was founded by Francisco Infante Aguirre and Thomas Hubregtsen in 2024. Francisco used to build hydrogen-powered supersonic planes at Destinus and heavy-lifting eVTOLs at Volocopter, but comes from a family that builds and sells tractor implements in over 25 countries. Thomas used to accelerate Machine Learning using GPUs, TPUs, and Quantum Computers at Google X, IBM and BMW, as well as started San Francisco-based Extropic introducing Thermodynamic computers, but also had his first job at a farm. Together, they set their sights on shaking up the market, competing directly with incumbents and startups alike. In their journey, they are supported by investors such as Extantia, Foodlabs, Antler, Push, and Prototype, who together committed a total of 9M in funding. With this, they were able to open up shop in a 1200 m² facility in Valencia, with 300 m² of natural‑light office and a 900 m² workshop. Valencia is consistently voted as one of Europe’s top p
