On-siteLos Angeles, California, United States or Denver, Colorado, United States
Job Summary
Lead LEO satellite electrical power subsystem design, development, and integration as a senior technical authority. Drive EPS architecture trades, requirements definition, and system-level performance analysis across all mission phases. Develop power budgets, models, and simulations to assess system performance under orbital conditions, eclipse cycles, and mission scenarios. Collaborate cross-functionally with systems, thermal, structures, avionics, and software teams to ensure compatibility and interface compliance. Champion R&D efforts to evaluate and mature novel power generation and energy storage technologies beyond current state-of-the-art solutions. Author and review technical documentation including specifications, interface control documents, test procedures, and engineering reports. Support integration and test activities, including anomaly resolution and root cause analysis. Provide technical mentorship to junior and mid-level engineers. Brief design and analysis results to program managers, government customers, and senior leadership.
