Mechanical Engineer PE I

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 I (PE I) applies fundamental engineering principles to design, analyze, and support mechanical systems for energy and infrastructure projects across hospital and college campuses. This includes developing code-compliant, constructible designs for HVAC, hydronic, thermal plant, and energy systems within defined project scopes. The PE I collaborates with multidisciplinary teams to coordinate designs with existing facilities, supports permitting and procurement efforts, and responds to field conditions. Responsibilities include preparing calculations, drawings, and specifications, maintaining design documentation, and contributing to systems that meet performance, reliability, and energy efficiency objectives consistent with ENFRA’s design-build delivery model.
