About the role

We are seeking an experienced and technically driven Electrical Engineer III – Spacecraft Programs (Electric Power Subsystem) to lead Electric Power Subsystem (EPS) development for next-generation Ranger spacecraft.

Responsibilities

• Lead Electric Power Subsystem (EPS) development across Ranger spacecraft programs from architecture definition through integration, qualification, and flight readiness
• Derive EPS subsystem requirements from spacecraft- and mission-level requirements while maintaining complete requirements traceability throughout development
• Author and maintain EPS Interface Control Documents (ICDs) while coordinating electrical and operational interfaces across spacecraft subsystems
• Perform spacecraft power generation, energy storage, and power distribution sizing analyses based on mission objectives, operational scenarios, and vehicle constraints
• Develop, maintain, and validate spacecraft power models throughout the full spacecraft development lifecycle
• Define and manage spacecraft power distribution architectures supporting avionics, propulsion, payloads, RF communications, and vehicle-level operations
• Resolve complex subsystem integration challenges involving power allocation, electrical compatibility, redundancy, fault management, and operational constraints
• Perform make-versus-buy trade studies supporting EPS hardware architecture, component selection, and procurement strategies
• Coordinate EPS hardware vendors, suppliers, hardware deliveries, and subsystem integration schedules
• Develop Electric Power Subsystem integration and test (I&T) plans supporting subsystem verification, vehicle integration, environmental qualification, and flight readiness
• Support spacecraft assembly, integration, environmental testing, launch campaign activities, and mission readiness
• Participate in major engineering reviews including System Requirements Review (SRR), Preliminary Design Review (PDR), Critical Design Review (CDR), Test Readiness Review (TRR), and Flight Readiness Review (FRR)
• Contribute to continuous improvement initiatives that strengthen spacecraft power system design methodologies, integration processes, and technical standards

Requirements

• Bachelor's degree in Electrical Engineering or a related technical discipline
• 7+ years of experience developing Electric Power Systems (EPS) for spacecraft or other complex aerospace platforms
• Experience deriving spacecraft power subsystem requirements and defining electrical interfaces across multidisciplinary systems
• Experience performing spacecraft power generation, energy storage, and power distribution sizing analyses based on mission requirements and operational constraints
• Experience developing and maintaining spacecraft power models throughout the product development lifecycle
• Strong understanding of spacecraft power distribution architectures and subsystem integration
• Experience working with high-power and high-current spacecraft electrical systems
• Experience managing hardware vendors, suppliers, and procurement activities supporting spacecraft development
• Strong systems-level understanding of spacecraft subsystem interactions and electrical integration
• Excellent analytical, technical communication, problem-solving, and cross-functional leadership skills
• Comfortable operating within a fast-paced spacecraft development environment with high ownership and execution expectations

Qualifications

• Master's degree in Electrical Engineering or a related technical discipline
• Experience working across multiple spacecraft subsystems including propulsion, avionics, communications, payloads, and GNC
• Experience developing high-voltage and mixed-voltage spacecraft Electric Power Systems (EPS)
• Hands-on experience supporting spacecraft Assembly, Integration, and Test (AI&T), including subsystem- and vehicle-level environmental qualification
• Experience supporting spacecraft mission operations following launch and deployment
• Experience leading hardware design reviews including schematic and PCB layout reviews
• Experience supporting reliability engineering, radiation effects analysis, EMI/EMC compliance, and fault-tolerant spacecraft design
• Knowledge of emerging spacecraft technologies for power generation, energy storage, and intelligent power distribution
• Experience supporting long-duration spacecraft missions in GEO, cislunar, or deep-space environments

Skills

• Strong analytical and technical communication skills
• Excellent problem-solving abilities
• Strong cross-functional leadership skills
• Ability to operate in a fast-paced, dynamic environment

Benefits

• Competitive salary
• Equity
• Comprehensive benefits including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing
