MATERIALS TEST OPERATOR, ($30-$45/HR)

• MATERIALS TEST OPERATOR, ($30-$45/HR)** **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 are designing and building commercially

viable fusion power plants. Since 2018, we have raised nearly $3

billion in capital and are the leading private fusion company in the

world. **Join the power movement as Materials Test Operator** The

Materials Department at CFS is looking for a materials test operator to

support our mechanical testing and characterization laboratory.

Materials at CFS supports the design and engineering of all components

needed for fusion systems and high-temperature superconducting (HTS)

magnets. Working closely with the team lead, the materials test operator

provides continuous support for both industry-standard and customized

mechanical testing - including tensile, compression, flexural, shear,

and fatigue. This role balances rigorous mechanical data acquisition and

equipment operation with metallographic specimen preparation and

microscopy. The operator is responsible for communication with internal

stakeholders, detailed data reporting, equipment maintenance, and

production line support. Laboratory capabilities include mechanical

testing (Universal Testing Machines such as Instron, load cells,

extensometers), metallographic specimen polishing and preparation,

microscopy, heat treatments, magnetic property evaluation, and other

thermophysical tests. **The Schedule** Full-time, on-site **What You'll

Do** - Prepare test specimens and perform laboratory experiments -

Execute materials test Jira tickets and QBench orders per standard

operating procedures - Operate industry-standard and customized

materials testing and characterization equipment and test methods -

Conduct mechanical testing including destructive testing (tensile,

compression, flexural, shear, peel, and fatigue) using Instron Universal

Testing Machines and custom tests across temperature ranges - Use

instrumentation including load cells, torque wrenches, extensometers,

strain gauges, calipers, and micrometers to ensure accurate data

acquisition - Perform metallographic sample preparation (cutting,

grinding, polishing), microscopy, hardness testing, magnetic and

electrical testing - Assemble custom fixturing and test stands for R&D

requirements - Maintain rigorous documentation to ensure data integrity

and effective troubleshooting throughout the test lifecycle - Support

equipment installation, maintenance, calibration, alignment, and

troubleshooting - Support inventory management for consumables and spare

parts and report purchasing needs - Support continuous improvement in

the materials test and characterization laboratory - Perform other

related duties as assigned **What We're Looking For** - High school

Diploma/equivalency Certificate Or Higher - Minimum 2 Years Experience with basic materials prep and testing tools - Minimum 2 years experience

with technical support skills including mechanical and electrical

assembly, vacuum systems, cryogenic systems, soldering, and wiring -

Meticulous attention to detail and ability to maintain data quality

while performing repeated tests - Ability to work in a fast-paced R&D

environment with daily changes - Strong problem-solving skills and

creative approach to new problems - Strong written and oral

communication skills - Proficient PC skills (Microsoft Word, Excel,

PowerPoint) - Ability to work independently and in multidisciplinary

teams - Ability to comply with, interpret, and support procedures, work

rules, and protocols - Commitment to CFS safety procedures and policies

• Bonus Points For** - Experience with Instron-based mechanical test

systems; Bluehill and Wavematrix software a plus - Testing to industry

or international standards (e
