Quality Engineer - Advanced Metrology Integration

About Commonwealth Fusion Systems

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent, and new technologies, we’re designing and building commercially viable fusion power plants. And we're working with policymakers and suppliers to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world.

Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.

If that’s you and this role fits, we want to hear from you.

Commonwealth Fusion Systems (CFS) is seeking a Staff Quality Engineer to serve as the subject matter expert (SME) for dimensional management and quality strategy for our HTS Magnet production and the SPARC Project. In this high-impact role, you will be the technical authority on Geometric Dimensioning and Tolerancing (GD&T), ensuring that novel, first-of-a-kind designs are translated into manufacturable and verifiable hardware.

The Staff role will be the technical authority responsible for taking "good enough" prints and collaborating with Manufacturing Engineering to develop the inspection infrastructure, tooling, and process controls required to build them. You will serve as the expert in applying GD&T to real-world fabrication challenges, ensuring that the SPARC project meets its mission through pragmatic, risk-informed quality solutions.

• Manufacturing-Driven GD&T Interpretation:
  • Take complex design requirements and work directly with Manufacturing Engineers to determine how to achieve critical tolerances using existing equipment and novel fabrication methods
• Proactive Problem Solving:
  • Lead the development of risk-informed QA controls that bridge the gap between design intent and shop-floor reality to positively impact the CFS mission
• Inspection Architecture:
  • Architect measurement systems and quality inspection methods specifically designed for the assembly of large metallic components, moving beyond theoretical models to executable floor-level plans
• Disposition Leadership:
  • Provide high-level leadership in dispositioning Non-Conformance Reports (NCRs), focusing on "use-as-is" or "rework" justifications based on structural integrity and functional requirements
• Process Stabilization:
  • Regularly analyze manufacturing data using control charts and process capability studies to identify where the "build" is diverging from the "print," escalating insights to Operations to drive immediate process adjustments
• Sub-system Integration:
  • Facilitate the creation and execution of PFMEAs and Quality Plans for the installation of sub-systems, ensuring that assembly tolerances are managed as the SPARC project scales
• Measurement System Analysis (MSA):
  • Lead advanced MSA and Gage R&R studies to ensure that the methods used to measure novel designs are statistically sound and repeatable in a production environment
• Mentorship & Oversight:
  • Provide technical coaching to QC Inspectors and Quality Engineers, specifically regarding GD&T interpretation on the shop floor

• BS in Mechanical, Industrial, Material Science or Manufacturing Engineering
• Minimum 10+ years of Quality Engineering experience in a manufacturing, assembly or equipment manufacturing environment, specifically focused on transitioning new products to production
• GD&T Expertise:
  Mastery of GD&T (ASME Y14.5) with a proven ability to translate theoretical tolerances into practical manufacturing work instructions
• Metrology:
  Deep knowledge…
