Principal System Integration Lead (Quantum Hardware)

PsiQuantumsmission is to build the first useful quantum computersmachines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016 our singular focus has been to build and deploy million-qubit fault-tolerant quantum systems.

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy pharmaceuticals finance agriculture transportation materials and other foundational industries.

Our architecture and approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industryincluding partners like GlobalFoundrieswe use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photonsdontfeel heat are immune to electromagnetic interference and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024PsiQuantumannounced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane Australia and Chicago Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically definingand that now is the time to scale.

PsiQuantumalso develops the algorithms and software needed to make these systems commercially valuable. Our application software and industry teams work directly with leading Fortune 500 companiesincluding Lockheed Martin Mercedes-Benz Boehringer Ingelheim and Mitsubishi Chemicalto prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shiftand a path to mastering challenges that cannot besolvedany other way. The potential is enormous and we have a clearpathto make it real.

Job Summary:

System Integration Lead will translate quantum system requirements into an implementable scalable hardware architectureand then drive cross-functional integration from concept through build test and deployment. This role sits at the intersection of quantum system architecture photonics/electronics hardware facilities and infrastructure and system design engineering. You will be a primary technical integrator and communicator who brings clarity alignment and execution discipline to a fast-moving environment.

Responsibilities:

• Translate system intent into hardware reality
  • Gather inputs from the Quantum System Architecture team and convert them into an implementable hardware architecture (requirements interfaces subsystems integration plan verification strategy).
  • Own end-to-end system-level requirements decomposition into subsystem specs (photonics electronics thermal mechanical controls firmware/software interfaces infrastructure).
  • Define and maintain the system architecture baseline as designs evolvemanaging changes while protecting system integrity.
• Lead cross-functional integration
  • Coordinate across internal teams including facilities photonics electronics system design engineers test/validation packaging thermal mechanical reliability and other technical leads.
  • Engage external stakeholders and vendors/partners as needed to ensure interface compatibility delivery alignment and integration readiness.
  • Drive integration readiness reviews interface alignment and subsystem bring-up plans.
• Own interfaces trade-offs and decisions
  • Establish and manage ICDs (Interface Control Documents) system block diagrams integration specifications and dependency maps.
  • Lead system-level trade studies and decision processes across competing constraints (performance reliability manufacturability cost schedule facility constraints).
  • Identify integration risks early and own mitigations contingencies and escalation paths.
• Build processes that scale
  • Create and continuously improve integration workflows that bring order without slowing innovation (e.g. requirements flow-down change control design reviews configuration management integration checklists).
  • Establish clear mechanisms for issue tracking root-cause analysis lessons learned and repeatable test/validation practices.
  • Help develop an integration culture that balances rigor with startup agility.
• Communicate clearly and drive alignment
  • Serve as a central communication hub across technical and non-technical stakeholders.
  • Provide concise updates on architecture status integration risks schedule impacts and decision needs.
  • Align teams through clear documentation structured meetings and effective stakeholder management.

Experience/Qualifications:

• Education & experience
  • MS in a relevant engineering field (Electronics Optics Photonics EE/CE Systems Engineering Applied Physics etc.) with 10 years of industry experience or
  • PhD in a similar field with 6 years of industry experience.
• Technical background
  • Demonstrated experience in electronicphotonics systems (mixed-domain integration: optical electrical thermal mechanical controls).
  • Strong understanding of system integration principles: requirements interfaces verification reliability and integration/test planning.
• Leadership
  • Prior experience in lead positions (technical lead system lead integration lead or program-facing technical leadership).
  • Track record of driving cross-functional execution and resolving complex technical dependencies.
• Communication
  • Exceptional written and verbal communication skills; ability to translate complex technical topics into clear decisions and actionable plans.
• Mindset
  • Strong positive attitude toward change and uncertainty; able to adapt quickly and navigate complex decision-making environments.

Preferred Qualifications:

• Background in data-center-scale system integration (large infrastructure facility constraints high availability safety commissioning operational readiness).
• Experience integrating systems that span facility hardware controls/software including deployment/commissioning in operational environments.
  • Familiarity with formal systems engineering tools and methods (MBSE DOORS/Jama configuration management structured V&V).
