Maintain and complete regular facility and security tours documenting and responding to found issues.
Provide applied mechanical and integrated control expertise for the entire data center
Serve in a technical writing capacity in regard to the derivation of procedures for preventative or corrective maintenance activities.
The job may require taking on on-call duties outside of normal working hours. 12-hr shift (night 7pm-7am) as needed for 24/7 coverage.
