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.
