Mechanical Engineer PE III

As the leader in Energy‑as‑a‑Service (EaaS), we integrate engineering, design, construction, financing, and long‑term operations into a single, accountable team—removing traditional barriers between design and execution. This means our engineers don’t work in silos or simply hand off drawings; they help shape full‑lifecycle solutions that reduce costs, improve performance, and create measurable, lasting value for our clients.

The Mechanical Professional Engineer III (PE III) serves as a senior technical leader responsible for the design, coordination, and delivery of complex mechanical systems for energy and infrastructure projects for hospital and college campuses. This role leads multidisciplinary design efforts, ensuring code-compliant, constructible solutions for HVAC, hydronic, and thermal plant systems. The PE III manages project execution for assigned scopes, mentors junior engineers, and resolves complex technical and field challenges. Responsibilities include overseeing design quality, supporting permitting and procurement, and ensuring systems meet performance, reliability, and energy efficiency objectives aligned with ENFRA’s design-build delivery model.
