Senior Project Manager, Mechanical Systems

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 Senior Project Manager, Mechanical Systems, owns the delivery of mechanical, utility, and energy infrastructure projects from first site visit through closeout. The role turns complex facility needs into well-scoped, financially sound projects, then leads the engineering, contractors, and field execution needed to deliver them safely, on schedule, and within budget.

This is a senior, client-facing role. The Senior Project Manager serves as the primary point of accountability for a portfolio of commercial, industrial, and public-sector projects, guides clients through investment decisions, manages project financials and risk, and mentors project engineers and coordinators. Success in this role directly drives client outcomes, project margin, and repeat business.

Within the first 12 months and on an ongoing basis, the Senior Project Manager will:

• Development quality: Deliver at least 95% of site surveys, feasibility studies, and investment-grade cost estimates by the committed deadline, with less than 5% requiring material rework due to engineering errors or omissions.
• Project pipeline: Develop technical scopes, project economics, and recommendations that generate at least $5 million annually in qualified project opportunities approved for proposal or implementation.
• Schedule and budget: Achieve at least 95% of scheduled milestones on time across assigned projects, and close projects within ±5% of the approved budget and at or above the estimated gross margin.
• Risk and change control: Identify, document, and upscale field issues, safety concerns, contractor delays, and client-impacting risks within 24 hours, and submit priced change orders within 5 business days of a scope change.
• Project records: Keep schedules, RFIs, submittals, action items, meeting notes, change logs, and closeout deliverables complete and current, with updates entered within 2 business days of receipt or occurrence.
• Client and team: Maintain positive client feedback and repeat or follow-on work with assigned clients, and develop at least one project engineer or coordinator toward independent project responsibility.

• Lead site surveys and collect technical, operational, utility, and cost data to establish project baselines and define client needs.
• Analyze facility infrastructure, utility systems, and operating conditions to identify energy, water, reliability, and operational improvement opportunities.
• Direct feasibility studies and technical evaluations for HVAC, central plant, utility modernization, and energy efficiency projects.
• Develop project scopes, engineering assumptions, savings calculations, lifecycle cost analyses, and investment-grade cost estimates.
• Prepare and present technical recommendations, project economics, and business cases that support client decision-making and proposals.
• Identify and integrate applicable utility incentives, rebates, grants, and other funding sources into project economics.

• Lead design engineering for approved…
