Ahmedabad, Gujarat, India catalyx space Full time ₹ 12,00,000 - ₹ 36,00,000 per year

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 efficient 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.
  • 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.

About Us:

We're building AWS for space, providing space experiments and technology demonstrations across LEO, deep space, and lunar orbit.

Our offerings include unmanned labs, testbeds for both dedicated and rideshare missions, and re-entry capsules for payload retrieval.

We simplify access to space with affordable pricing, end-to-end solutions, no minimum mass limits, zero integration fees, and quick deployment (6 months or less).

We serve biopharma, semiconductors, materials science, defense, and more.
