Security Clearance Requirements
Candidates must be able to meet Microsoft, customer and/or government security screening requirements required for this role. These requirements include, but are not limited to, the following specialized security screenings:
This role requires access to Microsoft Government cloud environments, including GCC Moderate (GCCM), GCC High (GCCH), and Department of Defense (DoD) environments. As a result, the successful candidate must be able to obtain and maintain the appropriate background investigations and customer screenings required for access to these environments.
For access to GCCH and DoD environments, this role requires the ability to obtain and maintain a favorably adjudicated Tier 3 (T3) background investigation.
For access to GCCM environments, this role requires the ability to meet Criminal Justice Information Services (CJIS) eligibility requirements.
For manager-level roles, a Tier 5 (T5) background investigation is preferred, as certain approval authorities and operational responsibilities require this level of screening.
Candidates may be considered without currently holding these background investigations, provided they are eligible for and able to successfully obtain them. Candidates may begin work while required background investigations are in progress; however, failure to obtain or maintain the appropriate clearance and/or customer screening requirements may result in employment action up to and including termination.
In addition, this position will be required to pass the Microsoft Cloud Background Check upon hire/transfer and every two years thereafter.
