BMS Estimator

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.

The BMS Estimator is responsible for developing accurate cost estimates and proposals for Building Management Systems (BMS), Building Automation Systems (BAS), HVAC controls, energy management, EPMS integration, and related facility automation projects. The successful candidate combines controls expertise, construction knowledge, operational understanding, and commercial judgment to create competitive and profitable proposals for commercial, industrial, healthcare, pharmaceutical, higher education, and mission‑critical data center projects.
