Power Systems Engineer

K2 Space • Los Angeles, CA

6h • Onsite

About The Position

K2 is building the largest and highest-power satellites ever flown, backed by $450M from leading investors and an additional $500M in signed contracts. The company is mass-producing high-power satellite platforms for missions from LEO to deep space, capitalizing on the new era of mass abundance enabled by heavy-lift launch vehicles. K2 satellites are engineered to survive harsh radiation environments and deliver unmatched capability at constellation scale across multiple orbits. With multiple launches planned through 2026 and 2027, K2 aims to develop the solar system and become a Kardashev Type II (K2) civilization. The Power Systems Engineer will develop and test high-fidelity electrical system models to ensure predictable and reliable behavior of the high voltage, high power system. This involves diving deep into power system first principles, creating full-fidelity SPICE models of power system parasitics and dynamics, and validating these models against reality. The role will guide key architectural decisions regarding power flow, fault isolation, EMI filter sizing, and reliable system operation through worst-case faults. This position is for individuals who enjoy hands-on investigation and want to influence the core architecture of next-generation spacecraft power systems.
