Mantis Innovation provides managed facility services and turnkey program management with technology-enabled solutions that target the entire building footprint. We look at the entire facility—inside and out—and can impact 70% of what a building operator allocates critical budget dollars toward, including: Strategic electricity and natural gas procurement, renewable energy, and demand response; climate impact reduction and reporting, net zero strategies, and sustainability planning; roofing, solar, HVAC assessment management, pavement, building envelope, data center optimization, and EV charging; lighting/LED retrofits, HVAC/mechanical systems, and BMS/BAS improvements and implementation. We deliver big mechanical projects for commercial and industrial clients. This role leads HVAC, boiler, chiller, and piping upgrades from start to finish. You run the field work, the schedule, and the client communication. You keep the job moving, the team aligned, and the work documented. This is a senior role. You'll handle large, complex Boston-area projects. You must be able to manage field crews, read drawings, solve problems fast, and track every detail.
