· 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. #J-18808-Ljbffr
