We are energized to grow, embracing opportunities to shape the future of a dynamic and evolving energy sector while advancing our careers. We are powered by teamwork, supported by diverse and passionate colleagues who foster respect, celebrate successes, and thrive on shared achievements. At the IESO, it’s not just what we do - it’s who we are! 

Who we are

Our central role includes managing the provincial power grid in real-time, overseeing and evolving Ontario’s electricity market, engaging with government, municipalities and Indigenous communities, and planning for Ontario’s future electricity needs. Our employees play a key role in driving grid innovation, protecting the system from threats, advancing the province’s energy conservation programs, and forecasting and procuring the electricity resources we’ll need in the decades to come.

This is a leadership position that falls within the Financial Resource Planning & Corporate Performance Division in the Corporate Services Business Unit.

What makes this role exciting

The energy sector is rapidly evolving, offering exciting new opportunities for those who want to make a difference.

We are hiring two Senior Manager positions within Financial Resource Planning & Corporate Performance Division. While both roles provide strategic financial leadership, oversight of planning and forecasting, and support the achievement of IESO's strategy, each role has a distinct area of focus.

This role will collaborate with senior leaders to drive initiatives that strengthen financial sustainability and support achievement of organizational goals.

Acting as the Director's delegate for business unit FP&A matters, this role provides trusted financial counsel to Senior Leadership Teams and delivers executive-level reporting and analytical insights that support decision-making at the Executive Leadership Team, Audit Committee, Board of Directors, and external stakeholder levels.

Senior Manager, Enterprise Corporate Performance, Projects & Planning

The Senior Manager, Enterprise Corporate Performance, Projects & Planning is a strategic finance leader responsible for shaping the organization's financial strategy, performance management framework, and capital and project financial planning.
