Company

Aerospace company developing autonomous spacecraft, advanced payloads, mission software, and space-based interceptors for U.S. and allied space-security missions.

What you will do

• Lead the design and development of spacecraft electrical power systems, including solar arrays, batteries, power distribution units, converters, charge controllers, and protection circuits.
• Own power architecture trades and technical decisions across performance, mass, thermal constraints, radiation tolerance, cost, and schedule.
• Develop power budgets, models, and simulations covering generation, storage, distribution, eclipse cycling, battery state of charge, and transient loads throughout the mission.
• Lead PDR/CDR activities and develop design specifications, interface documents, test plans, operating procedures, and qualification campaigns.
• Develop EGSE and HIL validation environments and support EMI/EMC, thermal-vacuum, vibration, and other environmental testing.
• Collaborate with avionics, systems engineering, software, and propulsion teams while mentoring junior and mid-level power engineers.

Requirements

• Bachelor’s degree in Electrical Engineering or a related field.
• At least 8 years of professional experience designing spacecraft or other high-reliability electrical power systems.
• Strong experience with solar arrays, Li-ion or LiFePO4 batteries, charge control, DC/DC converters, peak power tracking, and power distribution.
• Experience with radiation effects, radiation-tolerant design, power budgeting, system modeling, and simulation across all mission phases.
• Advanced experience with Altium Designer or equivalent ECAD tools and SPICE, MATLAB, or similar analysis tools.
• Ability to work fully onsite in Centennial, Colorado or Long Beach, California; U.S. ITAR eligibility and ability to maintain or obtain TS//SCI clearance are required.

Nice to have

• Master’s degree in Electrical Engineering, Aerospace Engineering, or a related field.
• Experience with fault management, autonomous protection, EEE parts screening, and qualification under EEE-INST-002 or NASA-INST-002.
• Familiarity with EMI/EMC standards, spacecraft charging effects, power-supply stability analysis, and GEO or LEO mission environments.
• Experience with EGSE, HIL testing, laboratory power equipment, or solar array simulators.
• Experience in a fast-paced startup or similarly dynamic environment.

Culture & Benefits

• Equity plus health, dental, vision, HRA/HSA options, PTO, and paid holidays.
• 401(k) and parental leave.
• Work takes place in a standard office and production-factory environment.
• Physical demands may include standing, sitting, walking, bending, and lifting or carrying items up to 20 pounds.
