Job Description

The BESS Electrical Design Engineer at Redwood Materials is responsible for leading the electrical design and integration of utility-scale energy storage systems, ensuring compliance with industry standards, and supporting grid interconnection and renewable energy projects.

Key Responsibilities

Lead electrical engineering efforts for utility-scale lithium-ion BESS projects from concept to construction.
Design AC and DC electrical systems for BESS, including specifying and procuring equipment.
Develop technical drawings, schematics, and protection strategies for electrical systems.
Coordinate with multidisciplinary teams to produce complete project packages and ensure code compliance.
Perform power system studies such as short circuit, load flow, and arc flash analysis.
Interface with utilities and regulatory bodies for interconnection, permitting, and compliance.
Serve as the Electrical Engineer of Record and ensure design quality and standards adherence.
Support grid integration and energy storage strategic initiatives through technical expertise.

Requirements

Bachelor's or Master's degree in Electrical Engineering from an ABET accredited program.
Licensed Professional Engineer in Nevada or eligible for reciprocity, with the requirement to obtain PE licensure in Nevada and South Carolina within 2 months of start date.
Minimum of 5 years of experience in solar, energy storage, or microgrid sectors, with at least 3 years focused on BESS design and deployment.
Proven expertise in interconnection and regulatory compliance for BESS systems.
Subject matter expert in knowledge of NEC 705, NEC 706, IEEE 1547, UL 9540, and NFPA 855 standards.
Advanced proficiency in microgrid and hybrid power systems modeling tools such as HOMER or similar, and power system modeling using ETAP, SKM, or similar.
Experience with AutoCAD, Revit, Navisworks, Bluebeam, and Microsoft Office.
Ability to perform power system studies including short circuit, load flow, arc flash, and protective device coordination for AC and DC systems.
Experience in designing AC and DC electrical systems for BESS using medium voltage transformers, inverters, DC combiners, energy managers, and battery modules.
Ability to specify and evaluate components such as circuit breakers, contactors, fuses, disconnects, emergency power off (EPO), and metering devices.
Experience in developing schematic diagrams, single-line diagrams, wiring schematics, raceway plans, grounding plans, and protection strategies for AC and DC systems.
Experience in coordinating with civil, structural, fire life safety, SCADA telecom, geotechnical, and DC system design teams to produce complete IFC packages and technical specifications.
Knowledge of applicable codes and standards such as NEC 705, NEC 706, IEEE 1547, UL 9540, NFPA 855, and local amendments, including leading code reviews.
Experience in integrating BESS with grid infrastructure and other renewable and traditional energy sources.
Ability to perform feasibility analysis of using medium voltage DC distribution systems for BESS integration with other sources.
Experience in providing construction administration support including RFIs, submittal reviews, change orders, and site inspections.
Ability to prepare engineering cost estimates and project schedules in collaboration with project controls at various design milestones.
Experience in performing QA/QC reviews of electrical designs and mentoring junior engineers.
Ability to contribute to internal design standards, templates, and best practices.
Experience managing project workload and ensuring timely delivery of engineering documents.
Strong understanding of energy storage use-cases including peak shaving, load shifting, demand response, and frequency response.
Highly motivated, proactive, and detail-oriented with effective communication skills through verbal, written, and visual formats.
