About Catalyx Space:

We're building AWS for spaceproviding in-space experiments and tech demos across LEO, deep space, and lunar orbit. Our offerings include unmanned labs, testbeds for rideshare and dedicated missions, and re-entry capsules for payload return. We simplify access with end-to-end solutions, no minimum mass limits, zero integration fees, and fast deployment (?6 months), serving biopharma, semiconductors, materials science, defense, and more.

Role:

Own the spacecraft Electrical Power System (EPS) end-to-endfrom power budgets and architecture through build, test, integration, and on-orbit support.

What you'll do:

• Define satellite power budgets from mission profile, subsystems, and orbit.
• Architect EPS (solar array conditioning, BMS, regulated/unregulated buses).
• Create schematics/PCBs; select converters, regulators, and PDU components.
• Analyze efficiency, thermal performance, redundancy, and fault-tolerance.
• Develop/validate MPPT and battery charge/discharge algorithms.
• Perform worst-case/derating studies and radiation-tolerance assessments.
• Lead FMECA and reliability risk mitigation.
• Source/evaluate space-qualified or Hi-Rel parts.
• Integrate and test EPS with OBC, payloads, ADCS, and comms.
• Maintain documentation for design, analysis, test, and integration.
• Support in-orbit ops (battery health, array performance, bus stability).
• Collaborate with systems engineering to optimize reliability, mass, and cost.

Minimum qualifications:

• B.E./B.Tech or M.E./M.Tech in EE/ECE/Power (or equivalent experience).
• Typically 26 years in spacecraft EPS or power-electronics hardware.
• Strong in DC-DC topologies, switching regulators, and BMS.
• Hands-on with KiCad/Altium/OrCAD; LTspice/PLECS (or similar).
• Knowledge of space-grade components, derating standards, and radiation effects.
• MATLAB/Python proficiency for power-budget modeling.
• Familiar with solar cells, Li-ion batteries, and power conditioning.
• Exposure to TVAC, EMI/EMC, and vibration testing.
• FMECA/reliability experience and strong documentation skills.

Nice to have:

• Spacecraft operations / on-orbit power management experience.
• Familiarity with ECSS/NASA power standards.
• Fault-tolerant/redundant architectures.
• Prior CubeSat/smallsat EPS development.

Compensation & benefits:

• Competitive salary (details will be shared with shortlisted candidates),
• health insurance
• Provident fund.
