What you’ll do

In this role, you’ll make a meaningful impact by contributing to the IESO team and supporting the electricity needs of the province:

• Lead market design projects across MEF priority focus areas, including distributed energy resources (DERs), distribution system operators (DSOs), demand flexibility (e.g., data centres, electric vehicles, hydrogen, and large loads), interties, storage, and operability services.
• Oversee the end-to-end market design lifecycle from issue identification, options development, cost-benefits assessment, implementation approach, and post-decision implementation support.
• Advise on, and actively participate in, policy and sector dialogue on the configuration of Ontario’s future energy system, and translate policy direction into implementable market design, program, and/or process changes.

• Support work planning, including identifying and prioritizing projects, allocating staff, managing timelines and budgets, and retaining/overseeing external consultants as needed.
• Lead formal stakeholder engagement and consultation, including designing engagement approaches, chairing/overseeing working groups, presenting proposals and analysis, and ensuring feedback is considered and addressed transparently.
• Represent the IESO as a senior market design authority, influencing internal leadership and external stakeholders through credible, evidence-based advice.

• Perform other responsibilities consistent with the role as assigned.
