Join to apply for the Assistant Project Manager - Mechanical role at Mantis Innovation

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).
  • Bachelor’s degree in mechanical engineering, construction management, energy systems, or a related field preferred — but not required.
$85,000 - $100,000 a year
