These competencies are crucial for developing high-precision optical components and ensuring efficient, reliable manufacturing processes.

What are some common challenges faced by Optical Process Engineers in a manufacturing environment?

Optical Process Engineers often encounter challenges related to maintaining tight tolerances and consistent quality during the fabrication of optical components. Variations in material properties, precision alignment, and contamination control require careful process monitoring and troubleshooting. Additionally, scaling up from prototyping to full-scale production can introduce complexities in process stability, equipment calibration, and cross-functional collaboration with design and production teams. Staying up-to-date with evolving manufacturing technologies is also important to ensure process efficiency and product quality.

What does an Optical Process Engineer do?

An Optical Process Engineer designs, develops, and improves manufacturing processes for optical components such as lenses, mirrors, and filters. They work to ensure high-quality production by optimizing fabrication techniques, troubleshooting process issues, and collaborating with design and production teams. Their responsibilities often include process validation, quality control, and the integration of new technologies to enhance optical component performance and efficiency.

Job description

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 Optical Process Engineer will be responsible for process development and assembly build with quality for R&D and volume system integration and deployment at PsiQuantum. This role requires engineering disciplines in packaging, processing, and associated qualifications, a strong "can-do" attitude in a fast-paced environment, problem-solving, and excellent communication with teams across multiple disciplines
Responsibilities:
  • By working with the sub-assembly design and packaging engineering team, develop assembly process flows and build sub-assemblies for quantum computer (QC) subsystems with electronics and silicon photonics chips on PCBAs for both cryogenic and room-temperature vacuum systems.
  • By working with a cross-functional team and suppliers, finalize the design and assembly process flow using DFM, DFQ, and FMEA tools to meet design targets and requirements set by the sub-system team.
  • Deliver and verify equipment, tooling, and fixtures from suppliers with the support of the supply chain. Complete process development and buy-off, including process capability analysis and a report.
  • Release the assembly process document, work instructions, and control plans in the systems with change controls; train, audit, and release the processes and controls to the operations team for volume assembly builds.
  • Develop in-house processes with the Operations team and manage contractor manufacturing for external processes, and be responsible for process technical support.

Experience/Qualifications:
