Your missionAs anRF Power Systems 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 development, integration, and validation of the RF power system that enables plasma generation and sustainment in our air-breathing electric propulsion technology. You will work on the architecture and performance of RF generators, matching networks, RF power delivery chains and their interaction with plasma loads. You will also serve as the primary technical interface with external suppliers responsible for the development of the Power Processing Unit (PPU), ensuring alignment with system requirements and supporting integration, testing and verification activities. You will work closely with propulsion, plasma physics, avionics and systems engineering teams in a highly hands‑on environment, helping transform cutting‑edge plasma propulsion concepts into robust flight hardware.Your profileSpecific KnowledgeStrong understanding of RF engineering fundamentals, including power transmission,
