Senior Protection & Controls Engineer — East

Hiring Senior Engineer – Protection & Relay Engineering

ZA-33002
• Charlotte, NC (Hybrid)
• Compensation discussed during final conversation.

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 East Coast pipeline serves the Virginia, North Carolina, and Southeast data center corridors — the densest concentration of hyperscale construction in the country.

The work spans the same multi-vendor protection architecture: 2(N+1) medium‑voltage with IEC 61850 GOOSE, staged commissioning on live critical infrastructure.

• 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.

• Onboarded into an active East Coast 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.

• Owning a full protection scope end‑to‑end on an East Coast data center project.
• Leading witness testing sessions with prime contractor and owner representatives.
• Contributing to IEC 61850 GOOSE or RTAC automation logic on at least one project.

• 7+ years protection & controls engineering for medium‑voltage power systems.
• SEL relay programming experience (Quick Set, 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.

• 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.

• Travel 30–50% during commissioning phases, project‑dependent. East Coast sites primarily (VA, NC, GA, TN).
• Site Hours 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 switch gear, approach boundaries, LOTO procedures.
