Power System Engineer

Key Responsibilities:

• Define satellite power budgets based on mission profile, subsystem requirements, and orbital parameters.
• Design, simulate, and develop spacecraft EPS architectures including solar array conditioning, battery management systems (BMS), and regulated/unregulated power buses.
• Create schematics, PCB layouts, and perform component selection for converters, regulators, and power distribution units.
• Perform detailed power analysis, including efficiency, thermal load, redundancy, and fault tolerance.
• Develop and validate algorithms for power point tracking (MPPT) and battery charge/discharge cycles.
• Conduct worst-case analysis, derating studies, and radiation tolerance assessments for EPS components.
• Perform FMECA to assess reliability and mitigate risks.
• Support component procurement by identifying, evaluating, and sourcing space-qualified or high-reliability parts.
• Integrate and test EPS hardware with other subsystems (OBC, payloads, ADCS, comms).
• Prepare and maintain detailed documentation for EPS design, analysis, testing, and integration.
• Support in-orbit operations by monitoring battery health, solar panel performance, and bus stability.
• Work closely with system engineering to optimize EPS performance for reliability, mass, and cost.
  

Required Skills & Qualifications:

• B.E./B.Tech or M.E./M.Tech in Electrical Engineering, Electronics, Power Systems, or related field.
• 2-6 years of experience in spacecraft EPS, power electronics, or aerospace hardware development.
• Strong understanding of DC-DC converters, switching regulators, and battery management circuits.
• Hands-on experience with PCB design tools (KiCad, Altium, or OrCAD) and circuit simulation (LTspice, PLECS, etc.).
• Knowledge of space-grade power components, derating standards, and radiation effects on electronics.
• Proficient in power budget modeling and analysis tools (MATLAB, Python).
• Familiarity with solar cell technologies, lithium-ion batteries, and power conditioning techniques.
• Experience testing hardware under TVAC, EMI/EMC, and vibration environments.
• Experience with FMECA and reliability analysis for power systems.
• Strong documentation and reporting skills.
  

Nice to Have (Preferred):

• Knowledge of spacecraft mission operations and on-orbit power management.
• Familiarity with ECSS/NASA standards for spacecraft power systems.
• Background in designing fault-tolerant and redundant architectures.
• Prior hands-on experience in small satellite or CubeSat EPS development.
