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.
Mantis Innovation is a leading facility performance consultant and project delivery engine that delivers smart, sustainable solutions to improve building performance and unlock operational efficiency. We serve over 70% of what a building owner/operator spends on their facilities — from building envelope and pavements to mechanical systems, lighting, energy procurement, and more.
We are seeking a motivated and detail-oriented Assistant Project Manager (APM) to support large-scale mechanical retrofit projects for our commercial and industrial clients. This is an excellent opportunity for a junior professional to grow in a dynamic environment, gain hands-on experience in mechanical project delivery, and work alongside experienced project managers, engineers, and field teams.
Key Responsibilities
- Assist with site audits and data collection for mechanical and boiler systems.
- Support the development of project scopes, budgets, and schedules.
- Coordinate with utility partners to support incentive applications and compliance.
- Track project progress using Procore, Microsoft Excel, and Unanet (training provided).
- Help prepare client-facing documents, meeting agendas, and project deliverables.
- Maintain accurate project documentation and update shared folders regularly.
- Support vendor coordination, scheduling, and logistics.
- Attend site visits and OAC (Owner-Architect-Contractor) meetings; take and distribute notes.
- Collaborate with senior project managers to ensure projects are delivered on time and on budget.
Qualifications
- 2–4 years of experience in construction, mechanical systems, or energy efficiency project delivery (co-op/internship experience acceptable).
- Exposure to or understanding of boiler systems, HVAC equipment, or MEP projects.
- Experience using Procore, or similar project management platforms (e.g., Buildertrend, PlanGrid).
- Comfortable working with Microsoft Excel, Word, PowerPoint, and cloud file systems.
- Comfortable reading and understanding construction documents.
- Strong organizational and communication skills.
- Willingness to travel regionally up to 30% (mostly day trips).
