Power Electronics Engineer

About the job

About the companyOrbitAID Aerospace is building the foundation for a new era of on-orbit servicing and refueling, enabling satellites to operate longer, maneuver more freely, and deliver greater value in space. At the core of this vision is the development of standardized docking and refueling technologies and a future network of orbital fuel stations, transforming how spacecraft are designed, launched, and sustained in orbit. Our long-term goal is to make space operations more flexible, resilient, and sustainablewhere satellites are serviced, upgraded, and refueled rather than replaced. We are a small, driven team that values strong engineering fundamentals, ownership, and hands-on problem solving. At OrbitAID, youll work closely across disciplines, move quickly from concept to hardware and software, and contribute directly to building the space infrastructure that will power the next generation of missions.Role OverviewThe Power Electronics Engineer is responsible for the design, integration, and customization of Satellite Electrical Power Systems (EPS). This role focuses on spacecraft solar arrays, battery systems, and power electronics to ensure reliable power generation, storage, and distribution throughout all mission phases.Key Responsibilities

• Design, analyze, and manage satellite EPS architectures, including generation, storage, and distribution
• Design and integrate spacecraft solar panel systems, including array sizing, deployment considerations, and performance evaluation
• Manage satellite battery systems, including capacity sizing, chargedischarge profiles, degradation, and lifecycle considerations
• Support mission-specific customization of EPS and battery solutions based on power budgets and operational profiles
• Perform testing, validation, and troubleshooting of satellite power electronics and energy storage systems
• Provide technical support across design, integration, test, and mission readiness phasesRequired Qualifications
• Minimum experience of 2 years with satellite EPS, solar arrays, and battery-based storage systems
• Bachelors degree in Electrical Engineering, Power Electronics, or a related field
• Strong understanding of spacecraft power electronics, including DCDC converters, regulators, and power management units
• Solid knowledge of space-qualified battery technologies (Li-ion preferred), BMS, and power/energy budgetingPreferred / Highly Desired Skills
• Experience developing spacecraft power budgets and operational power modes
• Familiarity with space environments (radiation, eclipse cycles, thermal coupling) and their impact on EPS design
• Experience supporting environmental testing of EPS (thermal-vacuum, vibration)Nice to Have
