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‑tonne 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.
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, and founded San Francisco‑based Extropic introducing Thermodynamic computers, but also had his first job at a farm.
Tasks
You will work in a team of four people. You can assume the control system is up and running, a tele‑ops system can supervise, and an advanced sense‑and‑stop will dynamically prevent you from driving into things. Your task is to build the core autonomy algorithm, from the current GPS waypoint through A*‑like algorithms toward transformer‑based approaches or whatever you deem to be the state of the art.
- Select, train, and iterate on algorithms and machine learning models for autonomy.
- Design and run testing campaigns, both in virtual environments and out in the vineyards, olive orchards, and citrus groves.
- Define and implement verification and safety criteria.
- Own deployment: when we ship a new model, how we ship it, how we monitor it, and what needs to be communicated or changed for the end user.
- Work on data ingestion, if it fits your skill set.
If you have deep experience in only part of this stack, we are open to shaping the role or splitting it across autonomy engineering, data engineering, and/or cloud. That said, we strongly prefer “skunkworks‑style” teams where everyone has high ownership and broad autonomy.
Requirements
- Strong, hands‑on coding ability and solid software engineering fundamentals.
- Awareness of the state of the art in autonomous systems and a practical sense of what is actually ready for the field.
- A track record of deploying models that worked outside of a notebook or slide deck.
- Willingness to go on site and test on real machines with real constraints.
- Ability to work in a self‑directed way on your own topics, while actively collaborating with engineers, technicians, operators, and sales.
- Fluent in English; conversational Spanish is a plus.
- Ability to responsibly use AI.
Benefits
We offer a very competitive base salary, equity participation plan, and aid in relocation when needed. Most importantly, we want to offer perks that are important to you. We’d love to hear what you value!
