As an RF Engineer, you will contribute to the development of Kreios Space’s electric propulsion systems for Very Low Earth Orbit (VLEO).
Your mission will be to support the design, simulation, assembly and testing of RF and microwave antennas used in our air-breathing plasma thrusters, helping transform advanced research into robust, flight-ready hardware.
You will work closely with propulsion, plasma physics and systems teams in a hands-on environment, contributing to laboratory testing, data analysis and design iterations.

About us
We are leading the development of the first air-breathing electric propulsion (ABEP) system designed specifically for Very Low Earth Orbit (VLEO). This revolutionary engine enables satellites to orbit between 150 and 300 km by capturing and using atmospheric particles as propellant.
By eliminating the need to carry fuel onboard, we drastically increase efficiency and overcome the main challenge of atmospheric drag in VLEO. This disruptive technology opens the door to an entirely new generation of space services, from high-resolution Earth observation to near real-time communications.
To achieve it, we rely on a team of professionals who are passionate, visionary, and committed to pushing the boundaries of what is possible. If you share this passion and want to leave your mark on the future of the space industry, we want to meet you.
