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.
Join the power movement as a Contract Metrology Engineer
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 dimensional inspections and precision alignments on a wide variety of unique SPARC systems and structures according to the SPARC metrology plan.
What you'll do:
- Use laser trackers and other portable 3D metrology equipment to perform precision alignments and dimensional inspections in a manufacturing/job site environment on a variety of components varying in scale from handheld to full power plant
- Perform metrology tasks both independently and as part of a team according to the baseline metrology plan and the guidance of senior metrology staff
- Optimize measurement efficiency by utilizing logical portable 3D metrology sequences and industry best practices
- Maintain well-organized files and datasets that follow logical structure for ease of review as needed throughout the SPARC project
- Evaluate measurement uncertainty and how it relates to the accuracy of results
- Analyze and review metrology data for accuracy and effectively communicate results to stakeholders
- In adverse cases, work with stakeholders to create and execute a workflow that allows efficient and expedient completion of mis-alignment issues
- Exercise proper care and maintenance of metrology equipment to ensure operability and accuracy
- Occasionally collaborate with design/engineering teams to understand requirements and work with the metrology team to develop unique solutions that balance precision and accuracy with a demanding project schedule
- Occasionally assist with analysis of production metrology data of major SPARC components that overlaps with the overall precision alignment plan
- Assist with non-metrology assembly activities as needed when metrology activities are light
What we’re looking for:
- High School Diploma or equivalent
- 2+ years experience using laser trackers with non-contact laser line scanners
- 2+ years experience using SpatialAnalyzer metrology software for 3D data collection and advanced metrology analyses
- 2+ years of mid- to large-scale metrology in a manufacturing/jobsite setting (i.e. other than QC lab)
- Experience using non-contact laser line scanners for inspecting complex shapes and free-form features
- Experience with precision alignment of large, delicate, and complex structures in dense spaces
- Experience with large metrology control networks, multiple instrument setups, and alignments of components across multiple rooms without line-of-sight to reference objects
- Experience working as part of a multi-disciplinary team with different levels of engineering, manufacturing, or operations professionals
- Experience using CAD (e.g. NX, Solidworks, CATIA) to extract information for alignments/inspections
- Intermediate understanding of GD&T per ASME Y14.5
Must-have Requirements:
- Ability to occasionally lift up to 50 lbs
- Perform activities such as sitting, climbing, stooping, typing, and standing for extended periods of time
- Working from heights is required. Must be able to safely utilize fall protection for work at heights of up to 35 feet via MEWPs (i.e. boom lift, scissor lift), temporary platforms (i.e. scaffolding, custom platforms), and ladders when necessary.
- Ability to work in confined, tight, or awkward spaces
- Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
- Willingness to travel or work required nights/weekends/on-call occasionally based on evolving build schedule
