Administer and support Microsoft 365 services including SharePoint Online, Microsoft Teams, OneDrive, Microsoft Copilot, Exchange Online, and Power Platform.
Respond to service requests, incidents, and operational support activities in accordance with established service levels and operational procedures.
Configure, maintain, and support Microsoft 365 permissions, security groups, RBAC assignments, and governance controls.

Develop and maintain technical documentation, operational procedures, knowledge articles, and user support materials.
Assist with platform audits, reporting, compliance activities, and data analysis to support governance and operational requirements.
Support automation and process improvement initiatives using tools such as Power Automate, PowerShell, and Microsoft Graph.
Perform other duties as required in support of organizational objectives.

QUALIFICATIONS

Completion of a four-year university degree in Information Technology, Computer Science, Information Systems, Business Technology Management, or a related field.
Minimum 2 years of experience supporting or administering Microsoft 365 services in a corporate environment.
Experience administering Microsoft 365 workloads, including SharePoint Online, Microsoft Teams, OneDrive, Exchange Online, Microsoft Copilot, and/or Power Platform.

OPG is committed to fostering an inclusive, equitable, and accessible environment. If you require accommodation during the selection process, please contact [email protected]

What makes a career at OPG different?

With operations across Ontario, OPG is one of the most diverse power producers in North America. As the largest generator in Ontario, we meet approximately 50% of the province’s electricity needs, largely from low-carbon sources like nuclear and hydro.

As we work to achieve our vision of Electrifying life in one generation, OPG and our family of companies are also helping advance the development of new low-carbon technologies such as Small Modular Reactors (SMRs), refurbishment projects, and electrification initiatives to help power the growing demands of a growing economy. Join OPG and make history.

Please submit your application online at https://jobs.opg.com/. OPG thanks all those who apply; however, only candidates considered for an interview will be contacted.

Please note: All job postings at OPG are to fill existing vacancies within our organization.

OPG may use artificial intelligence (AI) tools as part of the applicant screening process. However, applications will also be reviewed by a member of our Recruitment team to ensure a fair and thorough assessment.

The base salary range considers many factors including, but not limited to experience, education, and training, including any collective agreement requirements for union represented positions. It is not typical for the salary to be offered near the top of the range, and salary is dependent on numerous factors. For management roles, the base salary range does not represent the total compensation package. The total compensation package for regular full-time management roles includes pay-for-performance programs for annual and medium time periods. Maintaining a high-performance culture and excellence is a core expectation of every member of our leadership team and is rewarded through the established compensation framework.

OPG is committed to employment equity. As such, we encourage applicants from equity-seeking communities (Indigenous Peoples, racialized persons, persons with disabilities, and women). We strongly believe that alleviating the under-representation of equity-seeking individuals will create a stronger OPG team and allow us to better serve the needs of our diverse communities.

In order to fulfill the above-mentioned purpose, priority in hiring may be given to qualified persons who self-identify as a member of equity-seeking groups as identified in the application process. This initiative constitutes a special program under the Human Rights Code/Canadian Human Rights Act.
