The Senior Design Engineer owns the technical design package for substation and transmission facilities — air-insulated (AIS) and gas-insulated (GIS) substations across 60 kV–500 kV. The role is hands-on design: producing and reviewing the diagrams, layouts, calculations, and specifications that define how a substation is built, and safeguarding design integrity and constructability throughout.

Beyond producing designs, the Senior Design Engineer conducts design reviews and QA/QC of work prepared by staff design engineers and outside consultants. The position is hybrid, combining a remote office with an assigned PG&E work location and periodic field visits.

•     Lead development of single-line and three-line diagrams, general arrangement / layout drawings, elevations, and sections for substation design packages.

•     Design grounding grids, raceway/conduit systems, AC and DC schematics, control-house layouts, and station-service systems.

•     Perform design calculations — bus and cable sizing, DC/station-service loading, grounding, lighting, and conduit-fill.

•     Develop equipment specifications (transformers, circuit breakers, switches, relays, switchgear) and bills of material (BOMs).

•     Conduct technical, cost-savings, and constructability reviews of design packages from internal engineering, subcontractors, and equipment factories.

•     Review and QA/QC design deliverables produced by staff design engineers and consultants for accuracy and standards conformance.

•     Support brownfield projects with on-site assessment of existing equipment, structures, and foundations, and resolve design conflicts and ambiguities.

•     Provide design support during construction and commissioning; incorporate field changes and maintain configuration control and as-built documentation.

•     Ensure compliance with the NEC, NESC, IEEE/ANSI, CPUC GO 95/128, and PG&E design standards (proper clearances, ratings, and protection).

•     Coordinate with CAD/drafting and adjacent disciplines (civil, structural, protection & control), and mentor junior design engineers.

•     Education: BS in Electrical Engineering from an ABET-accredited program (or equivalent).

•     Experience: 8+ years of progressive experience in high-voltage substation and transmission electrical design.

•     Licensure: Active California PE (Electrical), or ability to obtain by comity within an agreed timeframe.

•     Design proficiency: Demonstrated ability to produce and check substation design deliverables and calculations independently.

•     Tools: Proficiency with AutoCAD and/or MicroStation; familiarity with design/analysis toolchains.

•     Equipment & specs: Experience writing equipment specifications and BOMs; AIS and GIS substations.

•     Standards: Strong working knowledge of NEC, NESC, IEEE/ANSI, and applicable CPUC General Orders.

•     Communication: Clear technical documentation and effective coordination across disciplines.

•     MS in Electrical Engineering.

•     Direct experience with PG&E (or comparable IOU) design standards and numbered design criteria.

•     Protection & control design familiarity — one-line/three-line diagrams, AC/DC schematics, panel and wiring diagrams.

•     Grounding analysis experience (e.g., CDEGS) and seismic-design awareness for California sites.

•     Significant brownfield / retrofit design experience.
