• Lead business-focused marketing efforts for Grid Engineering & Interconnection with developers and utilities, and grow market awareness of E Source's capabilities by participating in industry events, managing trade-show prospecting — including pre-show outreach and post-show follow-up — and executing a targeted communication plan with clients.
• Track industry trends, E Source's competitive position, and the broader power industry landscape.
• Develop and execute strategic account plans for key customers, expanding relationships across engineering, operations, transmission planning, project development, and executive leadership.
• Partner with sales leadership and account management teams to continuously improve our prospecting, lead-development, and opportunity-creation processes.
