Metrology Engineer

Commonwealth Fusion Systems•Devens, MA

1d•$90,000 - $145,000•Onsite

About The Position

Commonwealth Fusion Systems (CFS) is an innovative clean energy company designing SPARC, a tokamak-style fusion power demonstrator able to achieve net energy plasmas. This demonstrator will lead to ARC, a power-plant scale fusion power generator system. SPARC includes high-temperature superconducting and copper magnets, thermal shields, cryogenic cooling systems, vacuum vessels, and plasma facing components, all of which are densely packed into a power system and are subject to large operational loads (thermal, electromagnetic, etc.). Critical to the success and performance of the device is the precise alignment and assembly of key systems and structures within the dense device assembly. As a Metrology Engineer on the SPARC Assembly team, your responsibility will be to utilize portable 3D metrology technology to perform mid- to large-scale precision alignments and dimensional inspections on a wide variety of unique SPARC systems and structures according to the SPARC metrology plan. We are a fast-paced, agile, growing company that values diversity of thought and creativity, looking to apply our knowledge to pioneer a new method of energy generation for the betterment of the world. We look for people who have bold new ideas and perspectives, enthusiasm, imagination, a pioneering spirit, and a talent for execution to join us in our endeavor to create new fusion power technology that could change the world.
