Hardware Electronics Engineer – High Voltage & Power Electronics

Nigrán, Spain
Full-time
Permanent employee

Your mission

We are looking for a Power Electronics / High Voltage Hardware Engineer capable of designing and validating electronic systems that generate, regulate and distribute power for space propulsion applications.

The ideal candidate has practical experience developing DC/DC converters, high-voltage electronics, and power conversion architectures, and is comfortable taking designs from concept through laboratory validation.

You will work closely with RF, Plasma, Systems and Mechanical Engineers to develop the next generation of electric propulsion hardware.


Key Responsibilities

  • Design, develop and validate power electronics hardware for space propulsion systems.
  • Develop DC/DC converters, high-voltage power stages and power distribution architectures.
  • Support component selection, PCB design reviews, hardware debugging and thermal management solutions.
  • Define and execute laboratory testing, performance analysis and system validation activities.
  • Contribute to the development of future Power Processing Units (PPUs) and collaborate with multidisciplinary engineering teams.

Your profile

  • Bachelor's or Master's Degree in Electronic Engineering, Electrical Engineering, Telecommunications Engineering, Power Electronics or a related field.
  • 3+ years of experience in power electronics development.

Essential Technical Skills


Power Electronics
  • Experience designing DC/DC converters and switched-mode power supplies (SMPS).
  • Understanding of voltage conversion, control loops and converter stability.
High Voltage
  • Experience with high-voltage systems and circuits operating above 300V.
  • Knowledge of insulation, protection strategies and HV safety requirements.
Hardware Design
  • Schematic capture, PCB design and analog circuit development.
  • Experience selecting power components such as MOSFETs, IGBTs, GaN or SiC devices.
Laboratory & Validation
  • Hardware bring-up, debugging and root cause analysis.
  • Experience using laboratory instrumentation and validating power electronics performance.

Why us?

Be part of a pioneering NewSpace company developing a propulsion technology that could redefine how satellites operate in Very Low Earth Orbit. You will work on challenging, first-of-their-kind power electronics developments with direct impact on future space missions.

Join a highly multidisciplinary team of experts in plasma physics, RF, systems and aerospace engineering, where you will take ownership of critical hardware developments from concept to validation. As Kreios continues to grow, you will have the opportunity to shape our in-house electronics capabilities and contribute to groundbreaking space technology

¿Quiénes somos?

Estamos liderando el desarrollo del primer sistema de propulsión eléctrica air breathing (ABEP) diseñado específicamente para la órbita terrestre muy baja (VLEO). Este motor revolucionario permite que los satélites operen entre 150 y 300 km de altitud, captando y utilizando partículas atmosféricas como propulsor.

Al eliminar la necesidad de transportar combustible a bordo, aumentamos drásticamente la eficiencia y superamos el principal desafío de la resistencia atmosférica en VLEO. Esta tecnología disruptiva abre la puerta a una nueva generación de servicios espaciales, desde la observación de la Tierra en alta resolución hasta las comunicaciones casi en tiempo real.

Para hacerlo posible, contamos con un equipo de profesionales apasionados, visionarios y comprometidos con superar los límites de lo posible. Si compartes esta pasión y quieres dejar tu huella en el futuro de la industria espacial, queremos conocerte.
