Axiom Space fosters a work environment inclusive of all perspectives. We are the pioneers of commercial space, leading the transformation of low-Earth orbit into a global space marketplace. Our mission-driven team is seeking a bold and dynamic Principal Electrical Power System Engineer who is fueled by high accountability, execution horsepower, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.
POSITION SUMMARY
Since Axiom Space is a very complex work environment, we are looking for a resilient, high-energy Principal Electrical Power System Engineer who understands power electronics deeply enough to turn that understanding into requirements, models, interface documents, and review products that withstand customer, partner, and supplier scrutiny.
The AxEMU PAC is composed of flight computers, radios, sensors, and network switches that enable communication and control during all aspects of a spacewalk. You will be responsible for creating the electrical and electronic components that manage commands, telemetry, and internal data flows, ensuring the suit operates reliably and meets mission objectives. The person in this seat owns assigned segments of that architecture end to end: the requirement, the analysis that backs it, the interface that exposes it, and the test that proves it.
KEY DUTIES & RESPONSIBILITIES
Own assigned segments of the Electrical Power System requirement baseline. Author verifiable requirements that state system properties rather than implementations, maintain traceability and verification methods, and close TBD, TBC, and TBR items with named owners and closing events
Model the system and produce the analyses that decisions depend on: power and energy budgets, load flow and voltage drop, transient and step load response, bus stability, fault current and protection coordination, inrush and capacitive load management, harness sizing, and efficiency and dissipation rollups
Evaluate power conversion approaches and their system level consequences, including control behavior, current sharing, efficiency, mass, thermal, and electromagnetic signature, and review and challenge designs at that level
Author and maintain power quality specifications for both sides of the interface: steady state voltage limits, ripple and noise, transient envelopes, stability criteria, and the limits imposed on power consuming equipment
Contribute to grounding, bonding, isolation, and ground fault detection architecture, and coordinate with the EMC control program on control plan compliance, test tailoring, and non-compliance disposition
Plan and support verification: verification matrices, test requirements and procedures, laboratory and engineering model test campaigns, power quality and stability measurement, fault insertion, and data reduction against acceptance criteria
Prepare, present, and defend material at SRR, PDR, CDR, Test Readiness Review, and Manufacturing Readiness Review, including to NASA and drive actions to closure
Mentor junior engineers, review their analyses and documents, and raise the technical standard of the team rather than only your own output
Communicate progress, status, risk, and options to stakeholders and…
