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. The heat envelope of next generation NPUs and SoCs has outgrown what mechanical fans can deliver inside the laptops, AI PCs, robots, and inference appliances that OEMs want to ship. The rise of agentic AI makes this sharper: as models run continuously on the device, planning and acting in the background rather than answering one prompt at a time, sustained compute and heat climb exactly where cooling is hardest. Better heat dissipation is becoming a precondition for the next wave of intelligent devices, and that demand is what is pulling us into high growth. 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. The actuator only cools when you feed it the right high voltage waveform. That power stage is the heart of the product, and we are hiring a Senior Power Electronics Engineer to own it. Traction and recognition • Backed by leading deep tech investors, including SOSV and HAX and Faber., • Recognized as deep tech pioneers by Hello Tomorrow., • Member of the NVIDIA Inception program., • Innovez 2026 finalist., • Unveiled the first laptop cooled by DBD plasma at CES 2026., • Showing the first NVIDIA Jetson cooled by DBD plasma at Computex 2026., • Labs in Newark, New Jersey and Madrid, Spain. The role 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. You will have real ownership of architecture and design decisions, and your work will move directly onto customer platforms, from AI laptops to robotics modules. What you will own • 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., • Evaluate and select converter topologies (resonant, flyback, push pull, switched capacitor) and drive the trade studies behind those choices., • Design the magnetics, including high voltage and high frequency transformers and integrated magnetic structures, and the associated switching stages., • Bring down size and weight so the converter fits the submillimeter, weight sensitive form factors of Edge AI devices, while holding efficiency., • 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. What you bring • 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., • Hands on high voltage experience, or clear adjacent experience and the appetite to go deep on kV class design, insulation, creepage and clearance, and safety., • Practical EMI and EMC skills: you have taken products through compliance, or debugged your way to it, not just read the standards., • Fluency with the bench: oscilloscopes, high voltage probes, power analyzers, and the discipline to work safely around high voltage., • Comfort with simulation tools (SPICE class circuit simulation; magnetics or FEA tools a plus) and with reading your own PCB layouts critically., • A product mindset: you care about size, cost, manufacturability, and reliability, not only the lab result., • Degree in Electrical or Electronic Engineering, or equivalent practical depth., • Working English. Spanish is helpful but not required. Bonus points • High voltage AC, plasma, electrostatics, X ray, ozone, or similar kV class applications., • Magnetics design for high frequency, high voltage transformers., • 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). Why join • Join a high growth startup riding the agentic AI wave, where cooling is turning from an afterthought into a gating requirement for the next generation of devices., • Own a core technology. The power stage is one of the two things that make the company work, and your design ships in the product., • Real impact, early. We are small, funded, and past the science risk (TRL 5 with qualification work in flight). What stands between us and revenue is engineering you will lead., • Hard, novel problems. Compact, efficient, quiet kilovolt class drive is genuinely difficult and rarely done well. You will not be maintaining someone else's reference design., • Work that shows up on stage. The drive electronics you build is what powers our demos at events like CES and Computex., • Competitive salary plus access to the company phantom shares plan, so you share in the upside you help build., • Hybrid working from our Madrid or Newark lab, alongside the team that builds and tests the actuators. Logistics • Location: Madrid, Spain or Newark, New Jersey., • Type: Full time, permanent., • Eligibility: You must have, or be able to obtain, the right to work in your location (Spain or the United States). How to apply Send your CV and a short note on a high voltage or power converter you took from idea to working hardware to Links to designs, papers, or teardowns welcome. YPlasma is an equal opportunity employer. xbhjioe We hire on the merits of the person and the work, and we welcome applicants of every background.
