CIP Requirement:

This position requires Critical Infrastructure Protection (CIP) access consistent with North American Electric Reliability Corporation (NERC) standards. The applicant considered for this role will be required to obtain and maintain CIP access for the duration of employment in this position. A full seven (7) year criminal history will be obtained through the pre-employment background check process (or, for current employees, through supplemental background check process) to fulfill the CIP access requirements. In addition, this position requires an additional background check every seven years to maintain access.

Hybrid: Employees in hybrid roles work both in their home offices (virtually) and alongside their colleagues (in person).

In order for employees to build strong relationships and to promote meaningful in-person interactions, hybrid employees are expected to work about 40% of their time in-person at an APS or other (non-home office) location.

*Employees are expected to reside in Arizona (or New Mexico for Four Corners-based employees).

*Working from a home office requires adequate technology and an appropriate ergonomic set up.

*Role types are subject to change based on business need.
