Senior Mechanical / Aerospace Engineer

Overview 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.

Tasks 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

Requirements 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

Benefits The company is headquartered in Valencia – regularly ranked among the best cities to live in Europe thanks to its affordable living costs, Mediterranean climate, and rich cultural life. Compensation includes a competitive salary and stock options. Relocation support is available, and benefits are tailored to what matters most to each team member.
