(NYSE:AMRC) is a leading energy solutions provider dedicated to helping customers reduce costs, enhance resilience, and decarbonize to net zero in the global energy transition. We are a trusted, full-service partner to public sector and government entities, K-12 schools, higher education, utilities, and healthcare customers across the U.S., Canada, the U.K., and Europe.\nAt Ameresco, we show the way by developing, constructing and operating tailored smart energy efficiency solutions, distributed energy resources, and infrastructure upgrades that drive cost savings, resilience, decarbonization, and innovation. Our comprehensive portfolio is built to address the challenges of today and adapt the future, ensuring long-term sustainability and success for our customers.\nAmeresco is seeking a Senior BESS Project Engineer to join our growing Renewable Energy team. This is a Senior level role for an experienced engineer who can independently lead complex Battery Energy Storage System (BESS) projects through design and development, and support integration and commissioning efforts, while serving as a technical resource and leader for the team. This is a remote position joining a partially remote team with home office based in the Phoenix, AZ area. This role is focused primarily on behind-the-meter (BTM) battery energy storage system (BESS) projects, serving as the technical owner of system integration and controls scope from design through commissioning. Knowledge of front-of-the-meter (FTM) projects is also beneficial.\nThe Sr. BESS Project Engineer reviews single line diagrams (SLDs) and system designs for accuracy and constructability while working closely with subcontract engineers and internal Ameresco departments to ensure that data monitoring equipment, protective relays, controllers, and related equipment are correctly specified, designed into the system, programmed, and installed per plan. The role then supports construction and commissioning resources in the field through utility and project-required testing to confirm proper system functionality prior to energization and handoff to operations. While the primary focus is BTM projects, this role is expected to be available to consult with front-of-meter (FTM) project teams and subject matter experts as needed.\nResponsibilities:\nDesign Review & System Integration\nReview single line diagrams (SLDs), control schematics, and BESS system designs prepared by subcontract engineers and vendors across multiple concurrent projects, with final approval authority on accuracy, completeness, and compliance with project and utility requirements\n\nDirect or personally confirm that data monitoring equipment, protective relays, controllers, meters, and communication/networking equipment are properly specified and designed into the system architecture; review and validate work product from self, subcontract engineer, and junior engineers.\n\nServe as primary point of coordination with internal Ameresco departments (engineering, procurement, construction, and operations) to align equipment selection and system architecture with project requirements and company standards\n\nLead review of vendor and subcontract engineer submittals, control narratives, and points lists for BESS controllers, PCS, EMS/BMS, and site controllers\n\nIdentify and resolve complex design gaps, conflicts, or constructability issues between electrical, controls, and monitoring scopes prior to installation, escalating and driving resolution across teams\n\nControls Programming & Installation Oversight\nDirect subcontract engineers and controls integrators to ensure relays, controllers, and monitoring equipment are programmed in accordance with approved design intent and sequence of operations\n\nVerify that programming and configuration of protective relays, site controllers, and data monitoring platforms reflect final as-built system design\n\nProvide Sr Oversight of and support field verification that equipment is installed per plan, including panel wiring, CT/PT installation, communication architecture, and device configuration across multiple concurrent projects\n\nDrive resolution of open items related to controls, relay settings, and monitoring equipment through construction completion, escalating and identifying risks as needed\n\nTesting, Commissioning & Utility Coordination\nSupport construction and commissioning resources in preparing for and executing utility-required acceptance testing, protection relay testing, and interconnection commissioning\n\nOversee and support project-required functional testing of the BESS, including controls sequence testing, communications verification, and data monitoring validation\n\nTroubleshoot system functionality issues identified during testing and commissioning, coordinating resolution with subcontract engineers, vendors, and internal teams\n\nReview commissioning documentation and test reports to confirm system functionality meets utility, interconnection agreement, and project requirements\n\nSupport punch list resolution related to controls, relays, and monitoring equipment through final acceptance and handoff to operations\n\nCross-Functional & FTM Consultation\nServe as a technical resource to Project Management and Construction teams on BESS controls, protection, and monitoring scope throughout the project lifecycle across a portfolio of projects\n\nServe as technical resource and maintain expert level working knowledge of BESS equipment manufacturers, controls platforms, and protective relay schemes relevant to BTM applications\n\nConsult with front-of-meter (FTM) project engineering teams and subject matter experts as needed to support larger-scale or utility-interconnected BESS projects\n\nDocument lessons learned and support development of internal standards for BESS controls and monitoring design review\n\nTeam Leadership & Mentorship\nMentor and provide technical guidance to entry and mid-level BESS Project Engineers, reviewing work product and supporting professional development\n\nEstablish and document best practices, workflows, and technical standards for BESS design review, controls programming, and commissioning\n\nAssist in onboarding new team members and building team capability in new BESS platforms, controls architectures, and testing methodologies\n\nContribute to continuous improvement of design review checklists, controls narratives, and commissioning templates\n\nPerform other duties as required\n\nMinimum Qualifications:\nBachelor's degree in Electrical Engineering, Controls Engineering, or related discipline, or equivalent relevant experience.\n\nMinimum of 7+ years of relevant experience in electrical design, controls engineering, protective relaying, or battery energy storage system (BESS) project work.\n\nDemonstrated track record of independently leading BESS design, review, controls integration, across multiple different concurrent projects.\n\nAbility to travel up to 50% of the time for site visits, testing, and commissioning support.\n\nAdditional Qualifications:\nWorking knowledge of protective relays, controllers, and data monitoring/SCADA equipment used in BESS or substation applications.\n\nFamiliarity with utility and project commissioning and testing requirements for distributed energy resources.\n\nExperience managing multiple concurrent projects and coordinating cross-functional and subcontract engineering teams.\n\nExperience with BESS platforms and equipment from major manufacturers (e.g., Tesla, Fluence, SMA, and similar).\n\nExperience programming or configuring protective relays (e.g., SEL, GE) and site/plant controllers.\n\nExperience with installation and commissioning of BESS and microgrid systems a plus.\n\nProfessional Engineering (PE) license considered a plus.\n\nFamiliarity with SCADA, EMS/BMS platforms, and communication protocols (e.g., Modbus, DNP3, IEC 61850).\n\nExperience supporting utility interconnection testing, relay testing, and commissioning activities.\n\nExposure to front-of-meter (FTM), utility-scale, or substation-interconnected BESS projects a plus.\n\nExcellent verbal and written communication skills; ability to coordinate effectively across subcontract engineers, vendors, and internal departments.\n\nProficient in Microsoft Office Suite (Word, Excel, PowerPoint); experience with AutoCAD or similar drawing review tools
