Energy Engineer (Mechanical)

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.

The Energy Engineer/Project Developer (Mechanical) supports the evaluation, development, and execution of energy efficiency projects across industrial, manufacturing, pharmaceutical, distribution, and complex commercial facilities. This role focuses on existing mechanical systems' performance, cost, constructability, and operational reliability.

This role combines technical field work, engineering analysis, and solution development. The ideal candidate has strong mechanical systems expertise, can confidently interface with customers, and is comfortable balancing both field-based assessments and detailed engineering calculations. The role requires strong independent engineering judgment, the ability to evaluate facilities end-to-end, and the discipline to translate findings into actionable project scopes. The Mechanical Solution Engineer works cross-functionally with Technical Solutions, Mechanical, BMS, and Sales teams to support project development from initial assessment through client delivery.

We offer a fantastic lineup of benefits, including Medical, Dental, Vision, FSA, HSA, 401k Matching, Paid Vacation, Paid Sick, Paid Holidays, Paid Parental Leave, Paid Short Term & Long Term Disability, Tuition Reimbursement, and a flexible hybrid work schedule (for office-based employees). Working at Mantis also brings tremendous professional development opportunities that allow you to make a real impact on both the company and your career!

Studies show that women and individuals from underrepresented groups often hesitate to apply unless they check every box. At Mantis, we’re committed to building an inclusive and equitable team—so if this role excites you, we’d love to hear from you, even if your experience doesn’t match every single qualification.
