Position Summary

We are seeking a Senior BESS Engineer to lead the electrical design and engineering of grid-scale and distributed Battery Energy Storage Systems (BESS), from early conceptual layouts through Issue for Construction packages and into commissioning. This role combines hands-on technical design with cross-discipline coordination and project execution support across the full BESS project lifecycle.

Key Responsibilities

Design & Engineering

• Develop conceptual layouts, one-line diagrams, three-line diagrams, schematics, and wiring diagrams for BESS projects, and carry designs through to complete Issue for Construction (IFC) packages.
• Prepare engineering drawings and construction documents, including site plans, conduit and cable sizing/routing, grounding design, general arrangements, and equipment and inverter layout drawings.
• Develop and review engineering design plans, technical specifications, equipment data sheets, cost estimates, purchase requisitions, and bid evaluations at each design milestone.

Technical Studies & Compliance

• Review system studies — short circuit, load flow, arc flash, and protection & relay coordination — using tools such as ETAP or SKM.
• Evaluate interconnection standards and regulatory requirements (e.g., FERC, NERC, IEEE 1547, UL 9540) and guide designs to ensure compliance, along with NEC, NESC, NFPA, IEEE, and applicable state/local codes.
• Review and validate electrical, civil, and mechanical system designs and vendor submittals for technical compliance and quality.

Cross-Discipline & Stakeholder Coordination

• Coordinate closely with civil, structural, fire & life safety, high-voltage electrical, SCADA/telecommunications, water, and geotechnical engineers to deliver complete, well-integrated design packages.
• Participate in design reviews and value engineering efforts with contractors, vendors, and permitting/governing agencies; serve as technical point of contact and represent technical solutions in meetings.

Construction & Field Support

• Provide construction-phase technical support, including bid addenda, submittal reviews, RFIs, construction progress reports, and change orders, incorporating agreed-upon changes into project documents.
• Conduct site walks and support field activities during installation and commissioning.
• Identify technical risks and propose mitigation strategies in coordination with project management, and provide guidance on design, construction, and commissioning schedules.

Project & Team Leadership

• Coordinate project workload and schedules to ensure on-time delivery of documents and milestones, and support business development activities.
• Support development of and updates to internal design guidelines, catalogs, and templates.
• Mentor and provide technical guidance to junior engineers and designers.

Required Qualifications

Education & Experience

• Bachelor's degree in Electrical Engineering or a closely related engineering discipline.
• Minimum of 5 years of experience in BESS, power generation, renewables, electrical distribution, or power system controls design.

Technical Skills

• Working knowledge of BESS technologies and their integration into traditional power generation and renewable energy facilities.
• Strong understanding of electrical schematics, single-line diagrams, equipment layouts, system studies, protection & control, and relay coordination.
• Proficiency with AutoCAD, Microsoft Office, and power system study software (e.g., ETAP, SKM).
• Familiarity with communication network topology, fire alarm systems, and applicable electrical codes and standards (NEC, NESC, IEEE, NFPA).

Professional Skills

• Excellent written and verbal communication skills, with the ability to produce clear, concise technical documentation for varied audiences.
• Strong organizational skills with the ability to manage multiple concurrent, complex, and time-sensitive projects.
• Ability to travel to project sites and industry events as needed.

Preferred Qualifications

• Professional Engineer (PE) license, or PE/EIT eligibility preferred but not required.
• Experience with EPC or design-build projects in the energy or critical infrastructure sector.
• Experience supporting BESS projects, including coordination with EPC contractors, OEMs, and design consultants. xhyhwjd
• Familiarity with commissioning protocols and close out procedures for electrical systems.
