Staff High Voltage Electrical Engineer, EPC

Redwood Materials is seeking a Staff High Voltage Electrical Engineer to join our EPC team. This role is central to the design of high voltage electrical infrastructure to support our mission: to build a sustainable circular economy for lithium-ion batteries by transforming recycled materials into high-quality inputs for new batteries.

Responsibilities

• Lead the design of high voltage AC electrical systems, specifically for industrial substations (69kV to 345kV) and their integration with upstream transmission lines and downstream MV distribution.
• Review and evaluate the design of existing substations to provide recommendations for improving reliability and stability.
• Develop single-line diagrams, physical layout and design, protection and control systems, relay design and coordination, and grounding plans for substations.
• Perform grid simulation and stability studies using industry standard tools such as PSSE, PSLF, PSCAD, ASPEN One Liner and similar software.
• Interface with utilities and ISO/RTOs to support interconnection studies, permitting, and compliance for new renewable and BESS projects.
• Perform short circuit, load flow, and arc flash studies.
• Develop relay settings using SEL AcSELerator or equivalent software.
• Evaluate and select high voltage equipment including switch gear, circuit breakers, transformers, reactors, PTs, CTs, and protection relays.
• Serve as Electrical Engineer of Record for assigned projects.
• Lead code compliance reviews (NEC, IEEE, NESC, NFPA) and provide technical guidance to internal teams.
• Collaborate with civil and structural engineers on substation layout, foundations, and site development.
• Support facilities, construction and commissioning teams with field engineering, testing, and troubleshooting.
• Review vendor submittals, RFIs, and shop drawings for technical accuracy.
• Participate in technical bid evaluations and identify scope gaps.
• Lead R&D efforts to perform feasibility analysis of using medium voltage DC distribution system for integrating BESS with other sources.
• Independently manage high voltage design packages from concept through commissioning.
• Coordinate with internal stakeholders and external consultants to align scope, schedule, and budget.
• Prepare engineering cost estimates and execution schedules in collaboration with project controls.
• Lead technical reviews and design optimization workshops.
• Mentor junior engineers and contribute to team development.
• Develop workflows, templates, and standards for high voltage design and simulation.
• Support strategic initiatives related to grid integration, renewable energy, and energy storage.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering from an ABET accredited program.
• Licensed Professional Engineer in Nevada or eligible for reciprocity. Must obtain PE in Nevada and South Carolina within 2 months of start date.
• Minimum 10 years of experience in high voltage electrical design, preferably in EPC environments.
• Advanced proficiency in:
• Transmission-level load flow and stability using PSSE and PSLF
• Electromagnetic Transient Simulations using PSCAD, EMTC or similar
• SEL Relay Settings using SEL AcSELerator or equivalent
• Relay coordination and fault studies using ASPEN One Liner or similar
• Power system modeling using ETAP, SKM, or similar
• Preferred proficiency in:
• Design of HVDC systems and converter stations
• Strong understanding of protection and control systems, SCADA, and substation automation.
• Highly motivated, proactive, and detail oriented.
• Ability to communicate effectively through verbal, written, and visual formats.
• Field experience in construction and commissioning of high voltage systems is highly preferred.
