Senior Electronics Systems Integration & Validation 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.

That approach has since been tested at the highest level of scrutiny the U.S. government applies to emerging technology, and it has held up. In 2025, PsiQuantum closed a $1 billion funding round that valued the company at $7 billion. In 2026, the U.S. Department of Commerce signed a $100 million Letter of Intent under the CHIPS and Science Act, followed by a $125 million agreement with DARPA under Stage C of its Quantum Benchmarking Initiative, PsiQuantum's most valuable U.S. government agreement to date. This year, we also broke ground on our utility-scale quantum computer in Brisbane, Australia, and continued building out our Chicago site. Victor Peng, our CEO, and co-founder Jeremy O'Brien, now Executive Chairman, lead a team and board that reflects how seriously the world is taking this build, joined this year by Intel's Lip-Bu Tan and Atomico's Niklas Zennström.

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 Airbus, 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 now have the funding, the government validation, and the sites under construction to make it real.

Job Summary:

The Senior Electronics Systems Integration & Validation Engineer is responsible for leading the integration, system-level verification and validation, and deployment of complex electronic, embedded software, firmware, FPGA, and control systems for photonic quantum computing platforms. This role develops integration strategies, test methodologies, and validation processes to ensure systems meet performance, reliability, and operational readiness requirements.

Responsibilities:

Experience/Qualifications:

• M.S. or Ph.D. in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field with 5+ years of relevant industry experience; or B.S. with 10+ years of relevant industry experience.
• Demonstrated experience integrating, verifying, validating, and troubleshooting complex electronic systems, including embedded software, firmware, FPGA-based systems, instrumentation, and control systems.
• Experience developing and executing system integration, verification, validation, factory acceptance testing (FAT), site acceptance testing (SAT), production bring-up, and structured root-cause analysis.
• Hands-on experience with high-speed digitizers, detector readout systems, data-acquisition systems, timing and synchronization electronics, FPGA-based instrumentation, or comparable high-performance electronic measurement and test platforms.
• Strong understanding of hardware/software interfaces, communication protocols, and system-level debugging across hardware, firmware, software, and control systems.
• Proficiency in Python or similar scripting languages for test automation, diagnostics, instrumentation control, and data analysis.
• Ability to interpret electrical schematics, FPGA interface documentation, system architecture diagrams, and engineering specifications.
• Strong analytical, communication, and cross-functional collaboration skills, with the ability to lead technical investigations and make sound engineering decisions in fast-paced development environments.
• Experience with photonic integrated circuits (PICs), single-photon detector systems, laser and fiber-optic systems, cryogenic instrumentation, or quantum technologies is highly desirable.
