Process Engineer

PsiQuantum’smission 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 approachisbased on silicon photonics. Byleveragingthe 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: photonsdon’tfeel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber‑optic infrastructure. In 2024,PsiQuantumannounced 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. 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 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. Itrepresentsa fundamental shift—and a path to mastering challenges that cannot besolvedany other way. The potential is enormous, and we have a clearpathto make it real. Come join us. Job Summary The Process Engineer will be responsible for assisting in the module assembly processes and maintenance of typical back‑end semiconductor packaging equipment and supporting Process Engineers on the development of key assembly steps leading to R&D and volume system process solutions at PsiQuantum. This role requires hand‑on experiences in packaging, processing and equipment handling, a strong “can do” attitude ensuring high‑quality standards and precision in all tasks. Your expertise will contribute to delivering exceptional product solutions to our internal and future external customers. Responsibilities By working with process engineers; fabricate and assemble electro‑optical devices, including die attach, wire‑bonding and inspection, with a focus on precision and quality. Under the guidance of Process Engineers, co‑design and co‑develop assembly process flow, and build subassemblies for QC sub‑systems with electronics and silicon photonics chips on PCBAs for both cryogenic and room temperature vacuum systems. Lead and manage assembly and testing tools to ensure optimal performance and throughput. Develop and implement “best practice” to enhance product integrity and operational efficiency. Collaborate with cross‑functional teams, including engineering and manufacturing, to streamline assembly design and production. Conduct complex troubleshooting and analysis of assembly equipment to resolve technical issues. Document processes, results, deviations from the standard operating procedures and lessons learned, contributing to continuous improvements. Experience/Qualifications Preferred Skills & Experience Ability to use data processing tools such as Python and JMP to assist Process Engineers. Demonstrated ability to support short deadline tasks, and to follow a disciplined work process. Able to work in a fast‑paced environment. Familiarity with back‑end semiconductor assembly processes, testing methodologies and equipment, including die attach, wire‑bonding, visual inspection. Excellent analytical and problem‑solving skills, particularly in high‑pressure environments. Positive attitude and always open to learn new knowledge and operation of new equipment. Good team worker and bring in positive attitude and always ready to help others. Qualifications Bachelors degree or equivalent experience in engineering, physics, or a related field. 2+ years of experience applying engineering principles to solve complex opto‑mechanical assembly process problems. Exposure to photonics sub‑assembly with experience in semiconductor packaging and inspection equipment, processes and material system (die attach, wire bonding, optical coupling, flip chip, underfill … etc.). Familiar with key opto‑mechanical packaging and assembly equipment and part supplier base and the quality system. Excellent written and verbal communication skills; Self‑starter. Demonstrated strong analytical and problem‑solving skills. PsiQuantum provides equal employment opportunity for all applicants and employees.
