What is energy efficiency and why is it important?

Energy efficiency refers to using less energy to perform the same task or provide the same service. This is achieved through technologies and practices that reduce energy waste and optimize energy use in homes, businesses, and industries. Improving energy efficiency helps lower energy bills, reduces greenhouse gas emissions, and conserves natural resources. It is a key strategy for combating climate change while also benefiting the economy by creating jobs and driving innovation.

What are the most common challenges faced by professionals working in energy efficiency roles?

Professionals working in energy efficiency often face challenges such as staying updated with rapidly evolving technologies, navigating complex regulatory environments, and securing buy-in from stakeholders for new initiatives. Additionally, they may encounter difficulties in quantifying energy savings and demonstrating return on investment to clients or management. Effective communication and collaboration with multidisciplinary teams, including engineers, building managers, and policy makers, are essential to overcoming these challenges and achieving energy-saving goals.

What are the key skills and qualifications needed to thrive as an energy efficiency specialist?

To thrive as an Energy Efficiency Specialist, you need a strong background in engineering, environmental science, or a related field, often coupled with certifications like CEM (Certified Energy Manager). Familiarity with energy modeling software, building management systems, and data analysis tools is crucial. Exceptional communication, project management, and problem-solving skills help you effectively collaborate with clients and stakeholders. These competencies enable you to identify, recommend, and implement energy-saving measures that reduce costs and support sustainability goals.

About Mantis

We help organizations improve how their buildings perform by bringing together energy, facility operations, and sustainability into one connected approach. At Mantis, our teams work across the full lifecycle of a facility-from planning and design to field execution and long-term asset management-across commercial and industrial portfolios, data centers, and complex mechanical systems.

Our work spans four core areas: Building Controls, Energy Efficiency, Energy Advisory, and Facility Management-covering HVAC/mechanical optimization, BMS/BAS and EPMS controls, lighting system upgrades, energy brokerage, roofing and building envelope assessments, construction management, and more.

Whether you're in sales, engineering, construction/project management, field operations, corporate, or technology, you'll play a role in delivering these solutions and helping clients improve facility performance.

  • Have you closed large, complex projects where multiple decision-makers, technical evaluations, and long sales cycles were part of the process?
  • Are you well-versed in the art of "building your internal team of experts" to leverage SME knowledge and uncover top solutions for clients?

If so, we'd love to talk.

The Sales Executive is responsible for driving new business and expanding relationships with large commercial and industrial customers across three of Mantis' core offerings, including Energy Efficiency, Facility Management, and Building Controls.

This role focuses on building a strong pipeline, developing client relationships, and closing complex, consultative projects. You'll take ownership of your sales goals, create momentum in your market, and lead customers through sales cycles that result in meaningful operational improvements.

  • Work with engineering and technical teams to develop scopes of work that address client goals, budgets, and operational challenges.
  • Adjust proposed solutions based on client feedback, technical findings, and project requirements.
  • Present recommendations and explain how they will impact building performance, operating costs, and facility operations.
  • Pull in the right internal experts to help solve client problems and strengthen proposed solutions.
  • Manage opportunities from first conversation through proposal, negotiation, and signed agreement.
  • Coordinate with internal and external stakeholders to align projects with utility incentives or funding where applicable.
  • Maintain accurate pipeline visibility and activity tracking in Salesforce.
  • Travel to client sites to support relationship development, facility assessments, and project planning.
MINIMUM QUALIFICATIONS
  • 5+ years of consultative B2B sales experience in: HVAC & Mechanical, Lighting & Controls, Facility Asset Management, Design & Construction Management, BMS/BAS, or EPMS.
  • Demonstrated success in solutioning and closing facility projects of $1M or more.
  • Experience selling into commercial or industrial environments
  • Proven ability to build pipeline and generate new business
  • Ability to communicate technical solutions in a clear, client-focused way
  • Strong communication and relationship-building skills
PREFERRED QUALIFICATIONS
