Senior System Electronics Integration Engineer

PsiQuantum’s mission is to build the first useful quantum computers—machines 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 approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry—including partners like GlobalFoundries—we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure. 

In 2024, PsiQuantum announced 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 defining—and that now is the time to scale. 

PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact. 

Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real. 

Come join us. 

Job Summary:

The Senior System Electronics Integration Engineer reports into the System Design organization. This role is responsible for the integration, validation and troubleshooting of complex electronic subsystems as part of the Electronic Distribution Network (EDN). This role will ensure multiple hardware subsystems operate together reliably and meet overall system performance requirements.

Responsibilities:

• Define and manage system interfaces, including power distribution, timing distribution, cabling, connectivity and integration of electronic subsystems and components.
• EDN rack/vacuum/cryo layout and connectivity.
• Develop and execute system-level integration and validation test plans to ensure hardware, firmware, and software works together effectively as a cohesive system architecture.
• Coordinate cross-functionally to meet requirements and schedule with System Design leads, Electronics Design, Packaging Design, Validation, System Commissioning, System Architecture, and Quantum Operating Software teams.
• Ensure compliance with system requirements, safety standards, and design specifications.
• Create and maintain documentation such as interface control documents, schematics, design specifications and contribute to system BOMs.

Experience/Qualifications:

Required:

• BS, M.S. or PhD in Electrical Engineering, Electronics Engineering, or a related field.
• 3+ years of experience in system electronics integration.
• Experience with clock distribution, power distribution, grounding schemes, FW validation and SW control.
• Experience with software controls in Python.
• Strong organizational skills, excellent communication skills, attention to detail and ability to multitask.
• Strong critical thinking skills, demonstrated problem-solving and debugging skills in complex systems.
• Ability to work independently with limited direction.

Preferred:

• Experience with hardware development of active photonic integrated circuits (PICs), optical transceivers, RF products.
• Experience with high-speed signal integrity or power electronics.
• Knowledge of EMI/EMC considerations and mitigation techniques.
• Experience with vacuum and cryo systems.
