We are seeking a Power Systems Engineer to lead the design and development of spacecraft Electrical Power Systems (EPS). You will be responsible for defining power budgets, developing architectures, creating schematics, and ensuring the spacecraft has a reliable and effective power subsystem. This role spans the full lifecycle of spacecraft power engineering, from design and procurement to integration, documentation, and in-orbit operations.
​

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.
