Gravitics is building large-scale orbital structures for commercial and government space missions. We're seeking a Senior Power Systems Engineer to take full ownership of the product lifecycle for an in-space electrical power system from initial design through build, integration, and deployment.
In this role, you will lead the development of robust, mission-critical power systems engineered to perform reliably in orbital environments. You'll own the complete technical scope, from architecture-level design trades to vendor coordination and qualification.
Key Responsibilities:
- Design, build, and test electrical power subsystems for flight hardware in orbital environments
- Define and maintain power system requirements and perform architecture-level design trades
- Analyze and validate power system performance against requirements through modeling, simulation, and testing
- Perform solar array sizing, including shading, peak, and average power analyses for orbital missions
- Assess radiation effects on electronics and develop mitigation strategies
- Conduct fault tolerance, redundancy, and reliability analyses for power systems
- Work cross-functionally with structures, thermal, avionics, and GNC teams to ensure power system compatibility with vehicle-level performance
- Support environmental qualification and acceptance testing, including thermal-vacuum, vibration, and leak/proof pressure testing
- Contribute to vehicle layout and packaging decisions, accounting for radiation exposure and thermal environments
- Interface with external vendors and suppliers, owning technical coordination, component sourcing, and qualification to ensure delivered hardware meets performance, quality, and schedule requirements
You are a self-starter who makes things happen. You excel at several things and are willing to take on efforts in areas of weakness. You thrive in fast-paced environments with evolving priorities and collaborate effectively across multidisciplinary teams.
Requirements:
- Bachelor's degree in Electrical Engineering or closely related ABET-accredited discipline
- 5+ years of experience in power converter or electrical power system development
- Proficiency in designing and testing 1-10 kW power systems
- Familiarity with power system packaging, integration, and testing for space environments
- Strong problem-solving skills and ability to collaborate effectively across multidisciplinary teams
- Comfortable working in fast-paced environments with evolving priorities
Bonus Qualifications:
- Master's degree in Electrical Engineering or related field
- Experience with fault-tolerant design and FMECA for safety-critical systems
- Background working in configuration-controlled or safety-critical aerospace environments
- Prior experience with spacecraft electrical power systems (solar arrays, batteries, power distribution, or power electronics)
Note: To conform to U.S. Government space technology export regulations (ITAR), you must be a U.S. citizen, lawful permanent resident, protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain required authorizations from the U.S. Department of State.
