• Conduct regular inspections of facilities to identify potential hazards and ensure compliance of systems.

• Ensure strict compliance with applicable building codes, standards and regulations.

Vendor & Project Coordination

• Provide technical oversight and direction to external contractors and vendors for installations, repairs, and maintenance of building systems.

• Maintain accurate records and documentation of all building system activities and modifications.

You’d be a good fit with:

• Bachelor's degree in Mechanical or Electrical Engineering with a specialization in facility/building systems.

• Minimum of 13 yrs experience supporting highly technical environments.

• Experience in a high-tech manufacturing, semiconductor, or quantum computing research environment with critical building systems and managing critical clean room environmental requirements.

• Deep expertise in mechanical systems design (HVAC, process piping, equipment layout) and critical environmental control for labs/cleanrooms.

• Strong knowledge of electrical codes and standards (NEC, IEEE, NFPA 70E) and complex electrical infrastructure.

• Experience with PLC programming, SCADA systems, and building automation systems (BAS).

• Experience defining and implementing MEP standards and engineering requirements.

• Experience managing large-scale, technically complex projects with minimal oversight.

• Proficiency in facility management software (CMMS) and tools.

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.

US Non-Technical Jobs. Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
