About Guardian Energy

Guardian Energy Management Solutions is leading New England’s transition to smarter, cleaner, and more efficient buildings. Based in Marlborough, MA, we’re an energy services company (ESCO) that designs and delivers turnkey solutions, from HVAC and controls to electrical upgrades and full-scale decarbonization projects. Our clients include municipalities, schools, and commercial property owners who rely on Guardian’s in-house electricians, HVAC technicians, engineers, and project managers to reduce energy costs, modernize infrastructure, and meet aggressive sustainability goals.

The Opportunity

We’re looking for a seasoned Account Executive to expand Guardian’s footprint in the energy-efficiency and capital projects market. This is a consultative sales role for a professional who understands how to identify client needs, develop compelling project solutions, and close high-value opportunities with confidence.

You’ll have access to Guardian’s deep in-house technical resources, giving you the ability to offer design/build solutions rather than just selling concepts. Your work will directly contribute to New England’s path toward carbon neutrality, helping clients upgrade aging systems, electrify facilities, and reduce emissions.

What You’ll Do

• Lead with strategy: Identify and qualify new opportunities across municipal and commercial sectors.
• Consult with purpose: Conduct site assessments, uncover client needs, and translate findings into actionable project proposals.
• Collaborate to deliver: Partner with Guardian’s engineering, controls, and electrical teams to scope and price turnkey solutions.
• Manage the full sales cycle: From prospecting through contract execution.
• Build relationships that last: Develop and nurture long-term client relationships built on trust, technical credibility, and performance.
• Drive growth: Maintain a robust proposal pipeline and consistently meet or exceed sales goals.

What You Bring

• At least 10 years of progressive sales experience, ideally in energy efficiency, mechanical/electrical contracting, construction, or facility infrastructure projects.
• A proven track record of selling to C-level or senior decision-makers in commercial or institutional markets.
• Strong communication and negotiation skills with the ability to simplify complex technical concepts.
• Self-motivated, entrepreneurial mindset and comfort working independently in a fast-paced, results-driven environment.
• Bachelor’s degree in Business, Engineering, or related field (or equivalent experience).
• Proficiency in Microsoft Office and CRM systems.
• Valid driver’s license and willingness to travel locally within New England.

Why Guardian Energy

• Be part of a company driving the decarbonization of New England’s buildings.
• Competitive base salary + performance incentives.
• Comprehensive benefits: Health, Dental, Vision, Life, and Disability insurance, Paid Time Off, and a 401(k) with company match.
• A collaborative, technically sophisticated team that values initiative and long-term client success.
