Hiring Senior Engineer – Protection & Relay Engineering ZA-33002 • Charlotte, NC (Hybrid) • Compensation discussed during final conversation.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 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 IEC61850 GOOSE, staged commissioning on live critical infrastructure.What You Own Protection coordination studies for 2(N+1) medium‑voltage distribution per IEEE242.SEL‑751/700G relay settings packages with trip scheme logic diagrams.Woodward easYgen3400/LS‑6 generator controller programming and Modbus integration.IEC61850 GOOSE configuration for zone‑selective interlocking across PRP networks.SELRTAC‑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 SELWoodwardCAT (Caterpillar)ABBSoftware Tools AcSELerator QuickSetAcSELerator RTACSEL ArchitectETAPProtocols IEC61850 GOOSEDNP3Modbus TCPIRIG‑BStandards NFPA70EIEEE242 (Buff Book)IEEE1584IEC61850IEC62439‑3 (PRP/HSR)Test Phases Factory Acceptance Test (FAT)Site Acceptance Test (SAT)Secondary injection testingFunctional performance testingWitness testingWhat Success Looks Like First90 Days 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.First180 Days 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 IEC61850 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 IEEE242 — 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 NFPA70E arc‑flash safety and energized work practices.Preferred Background IEC61850 GOOSE configuration experience — SCL files, publish/subscribe, multi‑vendor interoperability.Woodward generator controller programming (easYgen3400, LS‑6, DTSC‑200).SELRTAC‑3530 automation logic (IEC61131‑3 Structured Text).NETA LevelIII orIV certification.Arc‑flash study experience per IEEE1584.What to Expect in the Field Travel30–50% 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 NFPA70E compliance required — arc‑flash PPE for medium‑voltage switchgear, approach boundaries, LOTO procedures.#J-18808-Ljbffr
