Field Test Engineer / Operator

Department: Engineering

Location: Paterna

Employment Type: FullTime

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 farmers are going to rely on these vehicles for many years to come, testing is of utmost priority. You will operate and test the vehicle in the field, lead demos, and close the loop with engineering. Your mandate: deliver reliable field evidence and successful demos. If you want a fast‑paced, hands‑on environment where what you build ships to fields and matters for Europe’s food security and defense, join us.

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 places to live based on its low cost of living, excellent climate, and vibrant historic centre. The team is young, comes from different backgrounds, and loves to have team bbqs, but share one aim: shape Europe’s agriculture and defence with machines that do real work.
