• Market Strategy: Execute go-to-market strategies tailored to the national utility environment, focusing on behind-the-meter applications and data center load growth
• Forecasting & Performance: Maintain a rigorous, data-driven approach to partner performance, using KPIs to manage pipeline health and provide accurate revenue forecasts to leadership

Qualifications & Experience:

• Sales Track Record: 8+ years of experience in energy, power generation, or critical electrical infrastructure sales with a proven history of hunting and retiring multi-million-dollar quotas ($10M+)

• Target Equipment Experience: Demonstrated success selling big-ticket, complex energy hardware (Generators, Turbines, Switchgear, Transformers, UPS Systems, Fuel Cells, Microgrids, or BESS)

• Partner & Channel Network: Strong existing relationships and a track record of driving sales through top US EPCs, electrical contractors, engineering consultancies, or distribution channels

• Technical & Financial Acumen: Comfort with project finance concepts (IRR, NPV, PPA structures) and the ability to articulate complex technical value to engineering C-suite stakeholders

• Drive & Mindset: Results-oriented hunter with a fierce sense of urgency, high energy, and a track record of closing deals in fast-paced environments

• Education & Travel: Bachelor’s degree required (Engineering, Business, or Quantitative degrees preferred). Ability to travel 40–50% nationally for partner closing meetings, field enablement, and key deal negotiations
