• Partner with the CTO to ensure our product capabilities are accurately represented in planning studies and regulatory discussions.

Strategy & Execution

• Own ON.energy’s ISO/RTO engagement strategy across key markets (e.g., ERCOT, PJM, MISO, SPP).
• Embed regulatory and grid requirements early in engineering design and customer contracting.
• Identify regulatory risks early and resolve them before they slow deployment.

Industry Leadership

• Build trusted relationships with ISO leadership, FERC staff, state regulators, and utility engineering teams.
• Participate in technical working groups and conferences to elevate us as a credible, policy-first voice on large load integration.

What We’re Looking For

• 3-5 years of energy policy advocacy experience.
• Background in power systems engineering, grid operations, or transmission planning.
• Direct experience with ISO/RTO stakeholder proceedings and tariff development.
• Ability to translate technical detail into clear, persuasive communication for non-engineering audiences.
• High ownership, sound judgment, and comfort operating in ambiguity.
• Graduate degree in EE or Energy Policy preferred.
