Senior Hardware Electronics Engineer – High Voltage & Power Electronics

Galicia, Spain · Full-time, on-site

My client is building Air-Breathing Electric Propulsion systems — satellites that harvest particles from the upper atmosphere and use them as propellant, powered by solar energy, to sustain operation indefinitely in Very Low Earth Orbit. Backed by over €22m in funding, including an €8m seed round led by the NATO Innovation Fund and JOIN Capital, the team is working towards an orbital demonstration of the technology.

We’re hiring a Hardware Electronics Engineer to own power-conversion hardware design at their flagship facility in Nigrán, reporting directly to the CTO.

What you’ll do

Design and validate power-conversion hardware from concept and schematic through prototype bring-up and lab validation — not integrating off-the-shelf modules, but building the circuits yourself.

What we’re looking for

⚡ 3+ years of hands-on power electronics development, with demonstrable ownership of DC/DC converter and high-voltage hardware design

⚡ Proven experience designing high-voltage circuits and/or power stages above 300V

⚡ Practical experience with switched-mode DC/DC converters — topology selection, power-stage design, component sizing

⚡ Strong understanding of converter control loops and stability

⚡ Working knowledge of HV insulation, isolation, creepage, clearance and protection requirements

⚡ Experience selecting and designing around MOSFETs, IGBTs, SiC and/or GaN devices

⚡ Experience with magnetics/transformers, thermal management and protection strategies

⚡ Schematic capture and power-electronics PCB design/review, including HV/high-current layout and EMI/EMC awareness

⚡ Hands-on bring-up, debugging and lab validation — oscilloscope and power measurements, efficiency characterisation, root-cause analysis

Compensation

We can offer excellent gross annual base salary, with flexibility for exceptional candidates with particularly strong HV/power-conversion experience.

Location

On-site in Vigo, Nigrán, Galicia. Open to candidates willing to relocate — relocation support available.
