Principal Power Systems Architect, Quantum Infrastructure

The role

This person will serve as the interface between hardware architecture, facility engineering, and internal electronics design teams. They will define how utility power is brought into the building, conditioned, distributed, isolated, and grounded to support large-scale quantum computing systems.

What you will do

• Serve as the primary technical interface between hardware architecture and facility engineering.
• Develop and own top-level specifications for facility electrical power systems.
• Define power quality requirements for sensitive hardware.
• Analyze and mitigate electrical noise, harmonic distortion, and EMI.
• Analyze and mitigate coupling paths between building-scale loads and noise-sensitive circuits.
• Define grounding, bonding, shielding, and cable management strategies.
• Establish architectural guidance for segregation and isolation of noisy and sensitive loads.
• Evaluate and specify isolation transformers, filters, and surge protection.
• Define UPS architecture and operating strategy.
• Partner with internal electronics and system design teams.

Required qualifications

• Master’s degree in Electrical Engineering or a related field.
• Significant industry experience in electrical power architecture, power distribution, power systems engineering, or infrastructure design for complex technical facilities or high-performance hardware
• Strong understanding of facility electrical systems, including utility interfaces, switchgear, transformers, distribution topologies, grounding/bonding, UPS systems, shielding, and power quality.
• Strong understanding of electrical noise mechanisms, harmonic distortion, conducted EMI, radiated EMI, transients, ripple, and interference propagation.
• Experience translating system-level electrical requirements into facility and equipment-level specifications.
• Strong knowledge of grounding, bonding, shielding, and EMC principles for mixed-signal or noise-sensitive systems.
• Experience evaluating and mitigating EMI, conducted noise, radiated noise, common-mode noise, crosstalk, harmonic issues, and interactions between high-power and sensitive electrical loads.
• Familiarity with AC-DC power conversion, power supply architectures, and equipment-level power distribution.
• Ability to work effectively across multidisciplinary teams.
• Strong written and verbal communication skills.

Nice to have

• PhD in Electrical Engineering or a related discipline.
• Experience with power distribution architecture in data centers or other large-scale mission-critical facilities.
• Experience designing infrastructure for highly sensitive scientific, semiconductor, cryogenic, computing, medical, or industrial systems.
• Deep understanding of power quality analysis, including harmonic distortion, sags, swells, transients, imbalance, flicker, and mitigation techniques.
• Experience with EMI/EMC analysis and mitigation.
• Experience specifying or selecting isolation transformers, filters, harmonic mitigation equipment, shielding approaches, and surge suppression solutions.
• Experience defining UPS strategies for mixed criticality loads.
• Experience guiding PCB/system electronics teams on grounding, shielding, EMI mitigation, and chassis integration.
• Familiarity with relevant electrical, safety, EMC, and facility design standards and codes.
• Experience supporting commissioning, validation, and root-cause analysis of complex electrical infrastructure.
