Senior Supplier Quality 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:

PsiQuantum is seeking an experienced Supplier Quality Engineer to manage quality performance at contract manufacturers (CMs). You will partner with engineering to translate product and process requirements into clear specifications and controls at the CM. You will also contribute to Design for Manufacturing (DFM) and Design for Excellence (DFX) reviews, using CM capabilities and production data to improve manufacturability, quality, reliability, and inspection readiness.

You will work with CM teams to establish statistical process control (SPC), sampling plans, and metrology methods that demonstrate compliance and help prevent defects. You will lead responses to quality excursions, coordinate investigations and corrective actions, and verify that improvements are effective. This role requires at least 10 years of experience in supplier or manufacturing quality for complex, high-reliability products.

Responsibilities:

• Partner with engineering to define product, process, inspection, and acceptance requirements for CM operations.

• Contribute supplier and manufacturing input to DFM and DFX reviews, identifying risks related to process capability, assembly, inspection, test, reliability, and scalability.

• Recommend design, material, tolerance, process, and inspection changes that improve manufacturability and reduce quality risk.

• Translate design intent and critical-to-quality characteristics into clear specifications, control plans, and inspection criteria.

• Work with CMs to establish and maintain SPC methods, sampling plans, measurement systems, and metrology requirements.

• Assess CM process capability and performance using data, audits, process reviews, and ongoing quality metrics.

• Lead responses to supplier quality excursions, including containment, root-cause analysis, corrective and preventive actions, and effectiveness checks.

• Coordinate cross-functional investigations with engineering, manufacturing, operations, and CM teams.

• Support CM qualification, process changes, first article reviews, and production readiness activities.

• Identify risks and trends, communicate quality status, and drive preventive improvements across the supply base.

• Maintain supplier quality records, nonconformance documentation, corrective-action tracking, and performance reports.

• Travel to CM sites as needed to support audits, investigations, and improvement work.

Experience/Qualifications:

• Bachelor of Science (BS) degree in Engineering required.

• Minimum of 10 years of experience in supplier quality, manufacturing quality, or a closely related role.

• Demonstrated experience managing quality at contract manufacturers and driving corrective actions through resolution.

• Working experience with semiconductor packaging or related precision manufacturing processes, such as die attach, wire bonding, fiber splicing, or optoelectronic box build.

• Practical experience developing or implementing SPC, sampling plans, inspection methods, and metrology requirements.

• Experience contributing to DFM and DFX reviews for complex products or manufacturing processes.

• Ability to interpret engineering drawings, specifications, process documentation, and measurement data.

• Strong problem-solving skills, including structured root-cause analysis and corrective-action methods.

• Clear communication skills and the ability to work effectively across engineering, operations, and external manufacturing teams.

• Ability to manage multiple supplier issues and priorities in a fast-moving environment.

Preferred Qualifications

• Experience with photonics, optical assemblies, or optoelectronic products.

• Experience qualifying new manufacturing processes or transferring products from development into contract manufacturing.

• Familiarity with quality-management systems and supplier audits.
