About UsAt ENFRA, we don't just design-we deliver outcomes that transform how energy infrastructure is financed, built, and sustained.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.
Our approach goes beyond the traditional models. We combine real-time collaboration with constructors, operators, and energy specialists to design systems that are not only technically sound-but constructible, operable, and optimized for lifecycle performance. Every project is grounded in accountability, data, and a commitment to delivering guaranteed outcomes-not just design intent.
Through our EaaS model, we empower clients to modernize infrastructure without upfront capital, while achieving guaranteed savings, improved resiliency, and long-term sustainability. Our teams play a direct role in accelerating the energy transition-delivering solutions that decarbonize facilities, enhance operations, and future-proof critical infrastructure.
At ENFRA, you'll join a multidisciplinary team that spans the full project lifecycle-from concept through optimization-giving you the opportunity to see your work realized, measured, and continuously improved. We value practical innovation, cross-disciplinary thinking, and engineers who want to make a real-world impact beyond the drawing set.
If you're looking to move beyond traditional design and be part of a model that is reshaping the industry-ENFRA is where engineering meets ownership, accountability, and impact.OverviewThe 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.
