Senior Protection & Controls Engineer — West

Hiring Senior Engineer Sacramento, CA (Hybrid) Why This Role Exists Every multi-vendor Tier III/IV data center protection system we deliver requires an engineer who owns the full P&C scope — coordination studies, relay settings, automation logic, and commissioning — under one accountability. This role exists because splitting that scope across firms creates handoff gaps that surface as retests during witness testing. Our West Coast pipeline serves the Northern California and Pacific Northwest data center corridors. The work spans 2(N+1) medium‑voltage protection with IEC 61850 GOOSE over PRP, multi‑vendor generator controls (SEL, Woodward, CAT), and staged commissioning on live critical infrastructure. What You Own Protection coordination studies for 2(N+1) medium‑voltage distribution per IEEE 242 SEL‑751/700G relay settings packages with trip scheme logic diagrams Woodward easYgen 3400/LS‑6 generator controller programming and Modbus integration IEC 61850 GOOSE configuration for zone‑selective interlocking across PRP networks SEL RTAC‑3530 automation logic: mode transitions, load shed/add sequencing, SOE concentration Commissioning procedures and witness test support through owner acceptance As‑built documentation packages for turnover to operations Systems You'll Touch Vendor Platforms: SEL, Woodward, CAT (Caterpillar), ABB Software Tools: AcSELerator QuickSet, AcSELerator RTAC, SEL Architect, ETAP Protocols: IEC 61850 GOOSE, DNP3, Modbus TCP, IRIG‑B Standards: NFPA 70E, IEEE 242 (Buff Book), IEEE 1584, IEC 61850, IEC 62439‑3 (PRP/HSR) Test Phases: Factory Acceptance Test (FAT), Site Acceptance Test (SAT), Secondary injection testing, Functional performance testing, Witness testing What Success Looks Like First 90 Days Onboarded into an active project — reviewed protection philosophy, existing settings, and one‑line diagrams Delivered first relay settings package (SEL‑751 or SEL‑700G) through internal review Participated in site commissioning or witness testing on a current project First 180 Days Owning a full protection scope end‑to‑end — from coordination study through commissioning plan Leading witness testing sessions with prime contractor and owner representatives Contributing to IEC 61850 GOOSE or RTAC automation logic on at least one project Required Background 7+ years protection & controls engineering for medium‑voltage power systems SEL relay programming experience (QuickSet, 751/700G families) with delivered settings packages Protection coordination study experience per IEEE 242 — time‑current curves, relay coordination Secondary injection testing with Omicron or Doble test sets — trip timing, coordination validation Commissioning experience on energized critical facilities (data centers, substations, or industrial power) Working knowledge of NFPA 70E arc‑flash safety and energized work practices Preferred Background IEC 61850 GOOSE configuration experience — SCL files, publish/subscribe, multi‑vendor interoperability Woodward generator controller programming (easYgen 3400, LS‑6, DTSC‑200) SEL RTAC‑3530 automation logic (IEC 61131‑3 Structured Text) NETA Level III or IV certification Arc‑flash study experience per IEEE 1584 What to Expect in the Field Travel 30–50% during commissioning phases, project‑dependent. West Coast sites primarily. Site hours include standard office hours for design; site hours during commissioning (early starts, occasional weekends near milestones). Customer‑Facing direct interface with prime contractor project managers and commissioning leads; owner witness testing coordinators during acceptance. Documentation Heavy — settings packages, coordination studies, trip scheme logic diagrams, commissioning procedures, as‑built documentation. Field Safety NFPA 70E compliance required — arc‑flash PPE for medium‑voltage switchgear, approach boundaries, LOTO procedures. Why Ziggurat Own the full scope — protection studies, relay programming, and commissioning under one accountability, not task fragments divided across firms Work across 8 manufacturer platforms (SEL, Woodward, CAT, ABB, Eaton, Cisco, EIG, UPS OEM), not inside one vendor ecosystem Direct access to the principal engineer — your technical judgment shapes project outcomes, decisions happen in conversations Shape how a specialized P&C practice scales from its founding stage into the data‑center market #J-18808-Ljbffr Ziggurat Automation Inc.
