Electrical Engineering Manager - Protection & Controls - Renewable Energy

McCarthy Building Companies, Inc. · Phoenix, AZ · 3 wk ago
EngineeringFull-time

Responsibilities

  • Lead development and application of the protection and control philosophy for renewable plants, MV/HV collector systems, substations, and gen-tie lines, including grounding and lightning protection interfaces.
  • Oversee P&C design deliverables (ex: SLDs/three-lines, AC/DC schematics, P&C schematics, wiring/logic diagrams, panel layouts, I/O lists, cable/conduit schedules) produced by internal teams and external EORs.
  • Direct or review protection and controls schemes and relay settings (e.g., SEL, GE, Siemens/Schneider), including trip logic, coordination, metering, alarming, SCADA points lists, and RTU/PLC/RTAC logic.
  • Plan, coordinate, and review power system studies that support P&C and interconnection (short-circuit, protection coordination, arc flash, grounding grid, and where applicable EMT/PSCAD, ETAP, and ASPEN OneLiner studies), leveraging internal and partner resources.
  • Ensure designs, studies, and settings comply with applicable codes and standards (NEC, NESC, IEEE/IEC, NFPA 70E), utility/ISO interconnection requirements, and project specific NERC PRC/modeling expectations where in scope.
  • Establish and enforce QA/QC procedures for P&C designs, models, and relay settings, including structured peer review, version control, and as-built documentation.
  • Lead technical coordination with utilities, ISOs/RTOs, owners, inverter/BESS vendors, and SCADA/telecom teams on protection schemes, ride through and reactive requirements, metering, communications, and OT network topology.

Qualifications

  • Bachelor’s degree in Electrical Engineering (power systems focus preferred) or closely related discipline.
  • 5+ years of power systems engineering experience, including 3+ years focused on MV/HV protection and control for utility, industrial, or generation/substation projects.
  • Demonstrated experience delivering P&C designs for HV/MV substations and collector systems (one lines/threelines, P&C schematics, panel layouts).
  • Strong working knowledge of protection applications for transformers, lines, buses, feeders, and breaker failure schemes, including relay settings review.
  • Experience with at least one major relay platform (e.g., SEL, GE, Schneider) and common communication/SCADA protocols (e.g., IEC 61850, DNP3, Modbus).
  • Proficiency with power system analysis tools (e.g., ASPEN, CAPE, ETAP, SKM or similar) for short circuit and protection coordination studies.
  • Familiarity with NEC, NESC, IEEE standards, and typical utility interconnection requirements for renewable generation.
  • Proven ability to lead and mentor engineers and communicate clearly with technical and non-technical stakeholders.
