We are seeking a BESS Electrical Engineering Manager to lead and oversee the company's battery energy storage systems (BESS) across its U.S. project portfolio, combining deep electrical engineering expertise with full ownership of BESS projects and technology.

WHAT DO WE EXPECT?

• Bachelor's degree in Electrical Engineering (or Electrical Power Engineering); master's degree is a plus.
• Hands-on electrical power system design expertise: single-line and three-line diagrams, protective relay coordination, grounding/bonding design, arc-flash analysis, and MV/LV electrical equipment specification.
• 10+ years of experience in electrical design, power generation and/or data center project development and delivery, including at least 4–5 years directly on BESS projects, in any application (utility-scale/front-of-meter, hybrid solar/wind+storage, C&I/behind-the-meter, microgrid, or data center).
• Demonstrated experience taking projects from design and engineering through construction management and commissioning.
• Working knowledge of BESS electrical balance-of-plant, protection and controls, and grid interconnection requirements.
• Experience with ISO/RTO interconnection processes and grid-code compliance (ERCOT or other ISOs/RTOs such as PJM, CAISO, MISO, ISO-NE).
• Ability to read and interpret power system study outputs (load flow, short circuit, protection coordination, EMT/dynamic studies) and translate them into design and project decisions.
• Working knowledge of NFPA 855, UL 9540/9540A, IEEE 1547 and NEC 705/706.
• Experience managing EPCs, OEMs and integrators, including technical contract negotiation.
• Strong written and verbal communication; comfortable presenting to executives, lenders and utilities.
• Authorization to work in the U.S.; willingness to travel to project sites (approx. 40-50%).

Preferred

• Professional Engineer (PE) license.
• Experience with ERCOT interconnection and modeling requirements specifically.
• Experience with data center power architectures (behind-the-meter generation, UPS/BESS integration, large-load interconnection).
• Hands-on experience running studies in PSCAD, PSS®E, ETAP or similar tools; familiarity with grid-forming inverter architectures.
• Familiarity with FAT/SAT for utility-scale battery systems and with SCADA/EMS/PPC integration.
• PMP or equivalent project management credential.
• Experience supporting financing, independent engineer or lender diligence.

WHAT AWAITS YOU?

• Own core electrical engineering deliverables for BESS scope, including single-line and three-line diagrams, grounding and bonding design, cable and conduit sizing, protective relay coordination studies, and MV/LV equipment specifications (switchgear, transformers, protection relays).
• Lead arc-flash hazard analysis and ensure electrical safety compliance (NFPA 70E) across BESS design, construction and commissioning.
• Define study scopes and review results for load flow, short circuit, protection coordination, harmonics and EMT/dynamic studies for BESS projects.
• Translate applicable codes and standards (NFPA 855, UL 9540/9540A, UL 1741, IEEE 1547, IEEE 2800, NEC Articles 480/705/706, IFC) into project design criteria and ensure compliance throughout design and construction.
• Lead interconnection strategy and compliance with utility, ERCOT and other ISO/RTO requirements for BESS assets, including model submissions, performance testing and ride-through requirements.
• Review and approve EPC, OEM and integrator engineering deliverables for BESS; run design reviews and manage technical change control.
• Define and maintain the company's BESS technical standards, basis of design, reference architecture and specification templates.
• Lead concept, preliminary and detailed design of BESS facilities: DC blocks, PCS/inverters, MV transformers, switchgear, collection systems, controls and auxiliary systems.
• Translate applicable codes and standards (NFPA 855, UL 9540/9540A, UL 1741, IEEE 1547, IEEE 2800, NEC Articles 480/705/706, IFC) into project design criteria and ensure compliance throughout design and construction.
• Review and approve EPC, OEM and integrator engineering deliverables; run design reviews and manage technical change control.
• Evaluate battery chemistries and system architectures (e.g., LFP, AC- vs DC-coupled, grid-following vs grid-forming) against project requirements for power generation and data center applications.
• Lead technical RFP/RFQ preparation, bid evaluation, clarifications and technical negotiation with battery OEMs, PCS suppliers, system integrators and EPCs.
• Define study scopes and review results for load flow, short circuit, protection coordination, harmonics and EMT/dynamic studies.
• Support interconnection strategy and compliance with utility, ERCOT and other ISO/RTO requirements, including model submissions, performance testing and ride-through requirements.
• Assess BESS integration with on-site generation and data center loads (power quality, backup/ride-through, islanding, load-following and peak-shaving use cases).
• Own the technical scope, schedule, budget and risk register for assigned BESS projects, in coordination with Program Management, Construction and Development teams.
• Manage engineering resources (internal and external), interfaces between disciplines (civil, electrical, controls, fire protection, permitting) and third parties.
• Support procurement, logistics and construction planning, including long-lead equipment tracking and schedule recovery.
• Report project status, risks and decisions to the Design & Engineering VP and senior leadership.
• Lead fire and life-safety strategy for BESS sites: hazard mitigation analysis, thermal runaway and explosion-control design, emergency response planning.
• Engage AHJs, fire marshals, insurers, lenders' and owner's engineers, and independent engineers during permitting, diligence and financing.
• Embed EHS and HSE requirements into design and contracts.
• Define and oversee FAT/SAT, commissioning, performance and capacity testing, and grid-compliance testing plans.
• Review SCADA, EMS, PPC and BMS integration and control logic alignment between OEM, EPC and project requirements.
• Ensure complete technical handover to O&M, including as-builts, procedures, spare parts strategy and lessons learned feedback into standards.
• Mentor engineers and build repeatable playbooks, checklists and templates for BESS delivery.
• Contribute to business development and technical due diligence for new U.S. opportunities, including data center-linked power projects.
