Senior Opto-mechanical Engineer

Employer description

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, suppliers, and many others to build the energy industry of the future.
 
We’re in the best position to make it happen. 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 Senior Opto-mechanical Engineer
 
Commonwealth Fusion Systems is currently assembling the SPARC tokamak, which aims to be the first magnetic fusion device to produce more fusion power than it consumes (Q>1). Achieving this mission depends on the diagnostic systems that deliver the scientific and controls data needed for successful
operation and provide valuable learning for ARC design. The Photonics Engineering department is seeking a Senior Opto-mechanical Engineer who will be embedded with the Long Wavelength Diagnostics team, helping to deliver diagnostic capabilities such as Laser Interferometry, Thomson Scattering, UV/VIS/IR Imaging and Spectroscopy, Electron Cyclotron Emission Radiometry, and Edge Scanning Reflectometry.
As SPARC moves from design into assembly and commissioning, this engineer will work with a cross- disciplinary team of diagnosticians, scientists, engineers, CAD designers, and technicians to close out the remaining designs and bring these systems from the tokamak, through the Tokamak Hall, and into the Diagnostic Labs. They will work to package optical and waveguide assemblies and the design of active and passive alignment systems that keep long beam paths aligned through thermal cycles, machine motion, and harsh environments expected during the operation of SPARC (high magnetic fields, vacuum, and radiation). As a senior member of the team, they will lead opto-mechanical work on medium to long-term problems, mentor other engineers, and help build CFS’s core competency in opto-mechanics for future CFS project work.
