Since 2000, we have served as a trusted partner to public and private sector customers across North America, the UK and Europe, delivering over $15 billion in solutions and contracting more than 5 GW of energy resources . At Ameresco, we integrate energy resources and modernize the built environment through innovative infrastructure solutions that improve reliability, optimize performance, strengthen resilience, and support long-term sustainability. Join us in building the infrastructure that powers the future. Explore opportunities to make a meaningful impact while growing your career with a company at the forefront of energy innovation. Ameresco is seeking a Senior Electrical Engineer to support the development, design, procurement, construction, commissioning, and operation of large-scale power generation and electrical infrastructure projects serving mission-critical data center facilities. This position will provide technical leadership for projects incorporating natural gas generation, renewable generation, fuel cells, battery energy storage systems, microgrids, utility interconnections, substations, and medium- and high-voltage electrical distribution systems. The engineer will support projects from early-stage due diligence and conceptual design through detailed engineering, construction, energization, and commercial operation. The position can be based in a hybrid arrangement in Knoxville, TN, Phoenix, AZ, or Dallas TX . Occasional travel to customer locations, project sites, vendor facilities, and commissioning activities will be required. Responsibilities: Lead electrical engineering activities for large-scale, mission-critical data center power projects, including on-site generation (engines, turbines, solar PV) and storage, substations, utility interconnections, microgrids, and medium- and high-voltage distribution systems. Develop and document the electrical basis of design based on customer requirements, anticipated data center load profiles, reliability objectives, utility requirements, project phasing, equipment capabilities, and contractual performance guarantees. Develop conceptual and preliminary electrical designs, including one-line diagrams, electrical site layouts, generation and distribution configurations, substations, collector systems, auxiliary power, station service, grounding, lightning protection, and protection, control, metering, and communications architectures. Establish design criteria for reliability, redundancy, availability, maintainability, system stability, fault-current capability, load acceptance, transient response, black-start capability, and phased load growth. Perform or oversee load flow, short-circuit, protection coordination, arc-flash, motor-starting, harmonic, grounding, cable ampacity, transient-stability, reactive-power, voltage-control, and generator or inverter-resource integration studies. Develop technical requirements and procurement specifications for substations, transformers, switchgear, generators, energy storage systems, protective relays, instrument transformers, conductors, bus systems, grounding systems, auxiliary systems, and other electrical balance-of-plant equipment. Support technical evaluation of equipment availability, performance, delivery schedules, commercial exceptions, warranties, testing requirements, and long-term service considerations. Lead or support utility interconnection applications, system-impact studies, facility studies, interconnection agreements, and coordination with utilities, independent system operators, transmission providers, and authorities having jurisdiction. Review customer load data and transient load profiles to confirm that proposed generation and storage systems can support steady-state and dynamic load conditions. Provide technical oversight and quality control
