Engineering Change Administrator / Mechanical Design Checker

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.

Job Summary:

The Engineering Change Administrator / Mechanical Design Checker manages the lifecycle of product changes (ECRs/ECOs), coordinating between engineering, manufacturing, and quality teams to ensure accuracy in designs and documentation. Key duties include initiating, tracking, and implementing revisions, reviewing impact on production/inventory, and maintaining clean records. 

This dual role also requires review of technical drawings, 3D models, and designs for accuracy, completeness, and compliance with standards (e.g., ASME Y14.5, ISO). Key responsibilities include checking GD&T, ensuring manufacturability, and verifying dimensions. Ideal candidates require at least 2+ years of experience, CAD proficiency, and high attention to detail. 

Responsibilities:

• Change Management: Control and track Engineering Change Requests (ECRs) and Engineering Change Orders (ECOs) from initiation to closure.
• Documentation Control: Maintain, update, and manage revision levels for drawings, Bill of Materials (BOMs), and specifications.
• Process Coordination: Facilitate reviews, impact analyses (cost, schedule), and approvals with engineering, procurement, and production departments.
• Database Administration: Input and maintain accurate data within Arena Product Lifecycle Management (PLM).
• Technical Review: Verifies 2D/3D drawings for errors, dimensioning accurac
