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 Grounding and Bonding Engineer Principal 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 Grounding and Bonding Engineer to own the electrical reference architecture of the station: where every power and signal domain is referenced, how isolation is maintained between domains, how every piece of conductive hardware is bonded to structure, and how all of it is verified on real articles rather than asserted in a drawing note.
The Axiom Space Station power architecture is a regulated high voltage dual bus system with multiple galvanically isolated domains, a distributed single point ground below the crossover frequency and a multipoint structure reference above it, secondary domains with different referencing treatments and therefore different fault behavior, orbital replaceable units whose bonds are remade on orbit by crew, and interfaces to the International Space Station and to visiting vehicles that have their own grounding conventions. The person in this seat owns the grounding and bonding plan, the requirements that come out of it, the flow into procurement specifications and supplier designs, and the verification evidence.
KEY DUTIES & RESPONSIBILITIES
Own the grounding and bonding plan and the requirement set that derives from it: grounding philosophy, reference architecture, isolation criteria, bonding classes, cable and shield treatment, charging and electrostatic discharge control, and the verification approach for each requirement
Define and maintain the reference architecture: domain boundaries created by isolating stages, the designated reference point of each domain, the reference network at each point, and the frequency at which the architecture hands over from single point reference to the structure as a distributed reference
Own isolation requirements across the system: primary to chassis, primary to secondary, and return to return between circuits, with the test potential, the measurement configuration, and the pass criteria defined so that the result means something on integrated hardware
Define the fault behavior that follows from each referencing choice, including which domains clear a first fault through a protective device and which limit it clears through the reference network, and coordinate the corresponding ground fault and isolation monitoring allocation with the power system and software teams
Own bonding class definition and the associated criteria: current return, shock and fault protection, electromagnetic and radio frequency, and electrostatic discharge, including direct current resistance and bond path impedance limits, faying surface preparation, method selection, and galvanic corrosion control across dissimilar materials
Drive bonding implementation into the design: bond identification and class…
