At Redwire, we’re breaking boundaries on an astronomical scale through innovation, meaningful impact, and continuous growth. Join us to be part of a mission-driven team where diversity, flexibility, and collaboration fuel every success. Summary: Redwire Space Missions LLC in Littleton, CO has an exciting opportunity for an Electrical Engineer. In this role, you will own the design, development, integration, and lifecycle support of spacecraft Electrical Power Subsystem (EPS) hardware. This includes power generation, energy storage, distribution, and conversion. The engineer will define EPS architectures, requirements, and interfaces; perform analysis; and lead verification and validation efforts. This role requires hands-on experience with spacecraft power systems and close collaboration with systems engineering, avionics, software, and I&T teams.
Job Responsibility:
Own spacecraft Electrical Power Subsystem (EPS) hardware design and performance from concept through delivery
Define EPS architectures, specifications, and interfaces with spacecraft bus and payload subsystems, including power generation, energy storage, power distribution and control
Develop power budgets, load analyses, state of charge analyses, and fault tolerance studies for missions
Support spacecraft integration and test with EPS checkouts, simulations, and anomaly resolution
Perform analysis of efficiency, stability, reliability, derating, and worst-case performance
Lead or support development and review of interface control documents (ICDs) for EPS hardware
Specify and procure EPS hardware and provide supplier technical oversight
Support environmental testing and verification in thermal vacuum, vibration, and EMI/EMC environments
Mentor junior engineers and contribute to electrical engineering best practices
Requirements:
Bachelor's degree in electrical engineering or related field (Master's preferred) with 5+ years of experience
Experience in power subsystem specification, development, and analysis
Experience developing power budgets, efficiency models, and load analyses
Experience performing as a Responsible Engineer or technical lead role for an EPS
Working knowledge of simulation and analysis tools (e.g., SPICE, MATLAB/Simulink, PLECS, or equivalent)
Must be US Citizen
Need ability to obtain a security clearance
Nice to have:
Master's or PhD in Electrical Engineering with specialization in power electronics with 8+ years of experience
Experience architecting end-to-end modular and scalable spacecraft EPS, including solar arrays, SADEs, SADs, batteries, and power control and distribution
Advanced understanding of battery systems, including sizing, charging, discharging, and thermal management
Experience developing and managing a Powered Equipment List (PEL)
Advanced understanding of solar array sizing, cell performance, and degradation analysis
Understanding of performance and trade-offs of battery types, such as Li-ion and NiH2
Understanding of radiation effects on power electronics and mitigation techniques
Knowledge of spacecraft avionics and bus interfaces (LVDS, MIL-STD-1553, CAN, SpaceWire, Ethernet)
Experience following EPS components through qualification and acceptance testing
Familiarity with high-reliability aerospace hardware design and derating guidelines (NASA, ECSS, MIL-STD)
Knowledge of standards and guidelines (NASA-STD-4009, ECSS-E-ST-20, MIL-STD-1547)
Strong hands-on experience with troubleshooting, fault isolation, and lab testing of EPS components
