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

Boeing•El Segundo, CA

8d•$98,600 - $197,800•Onsite

About The Position

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. 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.

Requirements

Bachelor of Science degree in Engineering, Engineering Technology (including Manufacturing Technology), Computer Science, Data Science, Mathematics, Physics, Chemistry or non-US equivalent qualifications directly related to the work statement
2+ years of related work experience or an equivalent combination of technical education and experience
2+ years of experience working with space related electrical power and harness subsystems

Nice To Haves

Experience with DC-DC converters and power electronics design to optimize efficiency and mass savings
Familiarity with electromagnetic interference (EMI) and electromagnetic compatibility (EMC) analysis, which is critical for power and harness integration
Knowledge of industry space qualification standards and guidelines, including radiation effects on power electronics and battery systems
Experience with software tools such as MATLAB/Simulink, PSpice, Schematic capture/ECAD tools (e.g., Mentor, Cadence), and power system simulation software
Understanding of failure investigations and root cause analysis (RCA) methodologies for spacecraft power anomalies
Ability to support mission operations with anomaly resolution and power subsystem troubleshooting

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
Review on-orbit power telemetry and generate tools and analyses to support customer on-orbit issues
Collaborate across multidiscipline teams (thermal, mechanical, software, avionics) to ensure design integrity and subsystem compatibility
