A day in this role
As an Assembly Test Implementation Engineer at CFS in Devens, expect to turn fusion hardware designs into repeatable build-and-test work: fixtures and procedures, instrumented runs, failure triage with design/manufacturing, and clear records so assemblies move from lab builds toward plant-ready configurations.
Strong fit if you like hands-on assembly/test ownership in a hardware-heavy fusion startup setting, on-site in Devens rather than remote.
