Since 2018, we’ve raised $4 billion of capital, making us the largest and leading 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. Join the power movement as a Metrology Engineer CFS is seeking a motivated Metrology Engineer to develop, validate, and deploy inspection methods for highly engineered hardware supporting the SPARC project. In this role, you’ll work hands-on with complex parts and advanced measurement systems, partnering closely with Supply Chain, Manufacturing, Design Engineering, Quality, and R&D to ensure hardware meets demanding performance and reliability requirements. You’ll thrive here if you enjoy solving ambiguous measurement problems, communicating clearly across disciplines, and building repeatable processes that scale. We’re looking for someone who takes ownership—from defining inspection strategy and tooling, to documenting methods and presenting results—while continuously improving how metrology supports production and engineering teams.
