Ontario Power Generation (OPG) is looking for a dynamic, strategic and results-driven professional to join our team in the role of Principal Solution Architect.

Job Overview

Reporting to the Senior Manager of Enterprise Architecture, this position is responsible to Architect and deliver a scalable, automated target-state digital landscape for post-modernization DNNP work, replacing retiring Asset Site 9 and paper-based procedures with well-documented best-practice designs and support processes that reduce manual administrative effort and ensure changes are implemented reliably end-to-end.

Key Accountabilities

Coordinate hybrid technology environments across cloud and on-premises data centres, supporting solution deployment, integration, performance, and ongoing operational requirements.

Enable enterprise system integration and digital processes through SAP platforms and related enterprise solutions, supporting secure data exchange and interoperable workflows across project and operational environments.
Support radiation protection digital solutions by maintaining and integrating systems, technologies, and monitoring processes related to dosimetry and radiation protection programs.
Enable monitoring, diagnostics, and data-driven decisions through the use of sensors, monitoring devices, and associated technologies that provide system visibility, data collection, and operational insight.
Support digital work execution and operational intelligence tools - including Aviva Connect, Aviva Predictive Analytics, digital workflows, dynamic instructions, and AI-enabled enterprise tools - to improve information access, predictive insights, field execution, and task completion.
Support engineering information and design workflows by working with engineering software, including the Hexagon product suite, to enable design collaboration, engineering data management, and integration with broader digital systems.

Qualifications

4-Year University Education in Computer Science, Engineering, or Information Systems
Requires over 10 years and up to 12 years of progressive experience in business and technology architecture, designing and delivering secure, governed, and scalable enterprise IT solutions - including cloud, microservices, APIs, integration patterns, operating models, technology roadmaps, and architecture frameworks such as TOGAF and ArchiMate - to address complex business challenges
Post-secondary education in computer science, engineering, information technology, or a related discipline, or an equivalent combination of education, training, and relevant experience.
Demonstrated experience with enterprise network and connectivity technologies, including routing, DNS, load balancing, and wireless solutions such as cellular, Wi Fi, Bluetooth, and near-field communication.
Experience supporting hybrid cloud and on-premises infrastructure environments, including solution deployment, systems integration, performance monitoring, and operational sustainment.
Knowledge of cybersecurity principles and controls, including firewalls, security monitoring, intrusion prevention, identity and access management, and zero-trust architecture.
Experience integrating enterprise applications and digital platforms, preferably including SAP, engineering information systems such as the Hexagon product suite, and digital workflow or work execution tools.
Experience working with operational technology, monitoring systems, sensors, diagnostics, or specialized digital solutions, with the ability to apply data, predictive analytics, and AI-enabled tools to improve operational decision-making and field execution.

The successful candidate will exhibit uncompromising integrity and commitment to upholding corporate values, and the OPG Code of Business Conduct.

OPG is committed to fostering an inclusive, equitable, and accessible environment. If you require accommodation during the selection process, please contact AODA@opg.com.

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.

The Darlington New Nuclear Project is leading the way in the advancement of Small Modular Reactor (SMR) technology in Canada – the future of nuclear power generation! Using new and innovative technologies such as small modular reactors, hydrogen and battery storage, while expanding our hydroelectric and nuclear portfolios, we are changing the electricity landscape in Ontario.

Important Information

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.

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.

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.
