Description

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. This role is for someone who wants to sit at the center of this scale up and shape what comes next: you will be the founders’ operator for the next phase of the company. You will run the operating cadence, own core metrics, shape capital strategies and unlock execution across engineering, manufacturing and field operations. This is a founder-track or COO-track role depending on the path you choose. You will have access, autonomy and the trust to make hard calls. This job is as broad as it gets: from ensuring the local painters get everything in shape for customer visits to representing us towards the EU Commission. 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.
