Sales Executive, Energy Efficiency & Facility Solutions

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.

• Are you a consultative seller who knows how to build pipeline and create opportunity?
• 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.
