YPlasma is a deep tech spin off from INTA, Spain's national aerospace agency. We build solid state, fanless cooling based on Dielectric Barrier Discharge (DBD) plasma actuators: flexible films, roughly 200 microns thick, that move air silently and on demand using ionic wind, at a fraction of the energy a conventional fan needs and with zero moving parts.
Our wedge market is thermal management for Edge AI. We focus on the edge, not the data center: the devices people hold and deploy in the field, where space, noise, dust, and battery budgets leave no room for a bigger fan. Our actuators target compute heavy edge hardware across computing, telecom, automotive, and electronics, with traction especially in the United States, Europe, Taiwan, and Japan. Electronics cooling is our main focus, but the same actuator platform, driven with different waveforms, also reaches into ice protection and surface heating, aerodynamic flow control, and other thermal and fluidic problems that we actively explore.
We are already running joint development programs with Tier 1 silicon vendors and global OEMs, backed by a granted core patent and a decade of transferred process know how. We are now industrializing the product and winning our first commercial designs.
That power stage is the heart of the product, and we are hiring a Senior Power Electronics Engineer to own it.
Backed by leading deep tech investors, including SOSV and HAX and Faber.

Labs in Newark, New Jersey and Madrid, Spain.
You will own the design of the high voltage converter that drives our actuators: a compact, efficient, electrically quiet power stage that turns a low voltage DC input into a controllable kilovolt range, kHz frequency AC drive. Today this drive electronics sits at the center of every customer conversation and every reliability question we need to answer to ship. You will take it from working prototype to a qualified, manufacturable product that integrates into customer hardware.
This is a senior individual contributor role reporting to the CTO and working side by side with our applications and plasma research engineers. Architect, design, and prototype high voltage AC drive converters for DBD actuators, from a few kV up to tens of kV peak to peak at Hz frequencies, optimizing for efficiency, size, and electrical noise.
Design the magnetics, including high voltage and high frequency transformers and integrated magnetic structures, and the associated switching stages.
Own EMI and EMC performance by design: active filtering, layout, shielding, and grounding strategy, with a clear path to FCC, CE, and customer specific compliance.
Plan and run reliability and qualification work (HALT, HASS, thermal, high voltage insulation and lifetime) and close the loop back into the design.
Build the test benches, instrumentation, and characterization methods needed to measure high voltage behavior safely and repeatably.
Support customer and OEM design in: translate the power stage into reference designs, answer thermal and electrical integration questions, and adapt the drive to customer hardware.
Drive industrialization and transfer of the converter to our microelectronics manufacturing partner, including design for manufacturing, documentation, and bring up support.
Contribute to our IP position through invention disclosures on drive electronics and integration patterns.
5 plus years designing switch mode power electronics through the full cycle, from concept and simulation to working, validated hardware.
~ Strong command of converter topologies, magnetics design, and closed loop control of power stages.
~ Degree in Electrical or Electronic Engineering, or equivalent practical depth.
~ Working English. Spanish is helpful but not required.
Experience taking hardware through OEM qualification, especially consumer electronics, automotive, or aerospace.
Design for manufacturing and transfer to a contract manufacturer or microelectronics partner.
Firmware or digital control for power converters (gate timing, waveform shaping, protection).
The power stage is one of the two things that make the company work, and your design ships in the product.
What stands between us and revenue is engineering you will lead.
Work that shows up on stage. The drive electronics you build is what powers our demos at events like CES and Computex.
Hybrid working from our Madrid or Newark lab, alongside the team that builds and tests the actuators. xpzdshu
