Satellite Electrical Power and Harness Systems Engineer (Associate, Experienced, or Lead)

Satellite Electrical Power and Harness Systems Engineer (Associate, Experienced, or Lead) Company: The Boeing Company Boeing Defense, Space & Security (BDS) is seeking Associate, Experienced, or Lead Satellite Electrical Power and Harness Systems Engineers (Level 2, 3, or 4) to join our team in El Segundo, California. The Space, Intelligence, and Weapon Systems (SIWS) team designs and delivers next-generation satellite products and services for both commercial and proprietary customers. Our team supports all engineering phases, including technology investment, concept development, proposal writing, requirements definition, design, build, integration, testing, and demonstration in operational environments. The Electrical Power System (EPS) and Harness Engineering team is responsible for the design, analysis, testing, and operation of power systems across a variety of vehicle classes. This includes power generation (solar arrays), power storage (batteries), power regulation (power controllers), and power distribution (harness systems). We seek candidates with a strong background in electronics hardware associated with power regulation and control, solar array unit design and testing, battery unit design and testing, as well as satellite vehicle testing and operational sustainment experience related to power systems. Ideal candidates will possess expertise in regulated power systems and familiarity with modern "battery-on-bus" architectures to enable future technology insertion.

Overview: As a Satellite Electrical Power and Harness Systems Engineer at Boeing, you will be part of a high-performing, dynamic team working on intensive satellite development projects. Your work will span power and harness subsystems for both one-time development and sustaining engineering efforts. Our team includes engineers focused on power system design and harness system design. While expertise in both areas is highly desirable, distinct roles exist during the design phase. Post-critical design reviews, during integration and test phases, these responsibilities typically consolidate under a single engineer. Below are the key responsibilities for this role:

Responsibilities: Define and refine requirements and develop verification artifacts for satellite electrical power and/or harness subsystems Perform detailed power subsystem analyses, including: Battery performance modeling and battery charge management planning, Bus voltage regulation and stability analysis (including ripple and transients), Redundancy and fault-tolerance strategies, Vehicle grounding and isolation philosophies Conduct harness analyses such as voltage drop calculations, fuse blow assessments, short circuit clearing, failure modes and effects analyses (FMEA) Develop, maintain, and update vehicle-level power budgets for all mission phases Assume end-to-end ownership of the EPS/harness subsystem throughout the spacecraft lifecycle Lead power subsystem architecture and sizing efforts, including block diagram development, solar array sizing, and battery capacity determination Define harness and interface requirements, including pin-to-pin assignments for the entire vehicle Provide system ownership for key power units including solar arrays, batteries, power controllers, solar wing deployment mechanisms, and battery charge balancing units or software Develop and review EPS/harness subsystem-level test procedures, and support vehicle integration and environmental testing Lead root cause and corrective action (RCCA) investigations related to the power and harness subsystem. Requires familiarity with constructing fault trees, logic flows and authoring non-standard test procedures Provide critical inputs to spacecraft databases, flight software teams, and flight operations procedures Lead power subsystem launch and mission readiness preparations, including on-console review for day of launch (DOL) and spacecraft initialization prior to handover to the customer
