Principal Power Systems Architect, Quantum Infrastructure

Job Summary Power Systems Architect, Quantum Infrastructure will serve as the critical interface between the hardware architecture team , the facility engineering team , and the internal electronics design team . This role defines how utility power is brought into the building, conditioned, distributed, isolated, and grounded to support a large‑scale quantum computing system with demanding requirements for power integrity, harmonic control, EMI mitigation, noise suppression, and system reliability. This person shapes the electrical foundation of a next‑generation quantum computing facility, ensuring that large building‑scale power systems and sensitive electronics are designed as one coherent architecture. The role is cross‑functional, covering electrical noise, grounding, shielding, transformers, UPS, filters, EMI, and power quality. Responsibilities Serve as the primary technical interface between hardware architecture and facility engineering for building power, conditioning, distribution, grounding, isolation, shielding, EMI, and power quality. Develop and own top‑level specifications for facility electrical power systems supporting quantum hardware, including utility power characteristics, distribution architecture, fault tolerance, redundancy, and maintainability. Define power quality requirements for sensitive hardware and translate those into actionable specifications for facility and equipment design. Analyze and mitigate the impact of electrical noise, harmonic distortion, voltage transients, conducted EMI, radiated EMI, and other interference on sensitive systems. Analyze and mitigate coupling paths between building‑scale loads and noise‑sensitive circuits and subsystems. Define grounding, bonding, shielding, and cable management strategies across the facility and equipment stack to minimize noise, crosstalk, harmonic propagation, and ground loop issues. Establish architectural guidance for segregation and isolation of noisy and sensitive loads, including panelization, transformer strategy, cable routing, shielding approach, and zoning. Evaluate and specify isolation transformers, filters, surge protection, harmonic mitigation, shielding, and other power conditioning approaches as needed. Define UPS architecture and operating strategy for different classes of loads, including selection, operating mode, ride‑through requirements, and interaction with downstream power supplies. Partner with internal electronics and system design teams to provide equipment‑level input derived from facility power conditions and distribution constraints. Guide electronics teams on grounding practices, including signal ground, chassis ground, bonding strategy, shielding implementation, and EMC‑conscious design. Provide architectural direction for AC‑DC power conversion and power supply unit requirements, including performance targets related to noise, ripple, harmonics, emitted, and reliability. Help define internal power distribution architecture from service entrance down to equipment‑level interfaces. Support system‑level trade studies involving efficiency, reliability, serviceability, safety, cost, power quality, EMI risk, and power integrity. Participate in design reviews with internal and external stakeholders to ensure alignment between facility infrastructure and hardware requirements. Identify technical risks related to power integrity, grounding, harmonic distortion, EMI/EMC performance, resilience, and integration, and drive mitigation plans early. Contribute to electrical design standards, interface control documents, and commissioning/validation strategies for facility and equipment power systems. Support installation, bring‑up, and troubleshooting of integrated facility and hardware power systems during commissioning and ramp‑up. Experience / Qualifications Master’s degree in Electrical Engineering or a related field. Significant industry experience in electrical power architecture, power distribution, or infrastructure design for complex technical facilities or high‑performance hardware systems. 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 in power systems and sensitive equipment. 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 loads. Familiarity with AC‑DC power conversion, power supply architectures, and equipment‑level power distribution. Ability to work effectively across multidisciplinary teams, including facilities, hardware, electronics, manufacturing, and operations. Strong written and verbal communication skills, with the ability to communicate complex technical concepts clearly across organizational boundaries. Preferred Qualifications 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 with demanding power integrity requirements. Deep understanding of power quality analysis, including harmonic distortion, sags, swells, transients, imbalance, flicker, and mitigation techniques. Experience with EMI/EMC analysis and mitigation, including conducted and radiated emissions and susceptibility considerations. Experience specifying or selecting isolation transformers, filters, harmonic mitigation equipment, shielding approaches, and surge suppression solutions. Experience defining UPS strategies for mixed criticality loads, including online versus eco‑mode trade‑offs, redundancy schemes, battery autonomy, and maintainability considerations. 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. Background in mission‑critical infrastructure, advanced computing, semiconductor fabs, research facilities, or large technical installations.
