What this job asks for AI summary
A senior systems engineering role on an R&D team, focused on owning and integrating complex utility subsystems — including vacuum pumps, chillers, and gas delivery modules — for experimental fusion energy equipment. Day-to-day work spans hands-on troubleshooting, authoring technical specifications, managing project schedules and budgets, and coordinating across mechanical, electrical, and software engineering groups. Suits an experienced engineer with a background in semiconductor or high-end R&D equipment environments.

Why we read it this way (8)
This role is fundamentally a Systems/Integration Engineer for complex R&D and semiconductor-style hardware — it does not map cleanly to any single SOC code in the computer/mathematical occupations list. 15-1299 (Computer Occupations, All Other) is used as the closest available code given the software control interface and cross-functional systems integration duties, but the primary day-to-day work is hardware/electromechanical systems engineering, which falls outside the standard tech SOC taxonomy. 15-1211 (Computer Systems Analysts) is noted as a runner-up due to the systems integration and requirements-authoring responsibilities.
The title says 'Staff Systems Engineer' and the posting explicitly frames it as a Staff-level role; the 12+ years requirement and org-wide cross-functional technical authority are consistent with Staff.
Degree requirement is marked None because the JD explicitly accepts 'equivalent industrial experience' in lieu of a degree.
PLC and control systems knowledge appear only under the 'Bonus points for' section and are therefore preferred, not required.
SEMI and ASME standards familiarity also appear only under 'Bonus points for' and are preferred.
Skills such as 'electromechanical troubleshooting' and 'vacuum systems' are named as concrete technical domains explicitly required in the qualifications section; generic responsibilities (project management, cross-functional leadership, SOP authoring) are omitted per schema rules.
Location is inferred as the Boston/Cambridge, MA area based on CFS's known headquarters; the posting does not explicitly state a city.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Process and Instrumentation Diagrams, electromechanical troubleshooting.
