Commissioning & Field ExecutionNationwide (Field-Heavy)Hiring Principal EngineerZA-35011Nationwide (Field-Heavy)Field-HeavyCompensation discussed during final conversationWhy This Role ExistsEvery commissioning scope on energized MV switchgear requires someone who manages the safety boundary — the person who establishes approach limits, verifies PPE, coordinates LOTO, and controls the energization sequence. This role exists because energization safety on 2.4 kV switchgear with concurrent energized and de-energized zones cannot be an afterthought delegated to the lowest-available person. You own the safety plan for every commissioning phase. When boards are being cut over while adjacent boards serve live loads, you define the approach boundaries, manage the energization sequence, and verify compliance before power is applied.What You OwnEnergization procedures and safety plans for multi-source MV critical power facilitiesLOTO procedures and verification for concurrent energized/de-energized zones on adjacent switchboard sectionsApproach boundary management (limited, restricted, prohibited) per NFPA 70E 130.4(E)Arc-flash PPE category assignments based on IEEE 1584 incident energy calculations across all operating modesDaily safety briefings, qualified electrical worker rosters, and safety documentation for each commissioning phasePre-energization safety walkdowns — verifying all safety boundaries, PPE, and isolation points before power is appliedCoordination with site stakeholders: Operations, Safety, Mission Assurance (or owner equivalent)Systems You'll TouchStandardsNFPA 70E NFPA 70 (NEC) NFPA 110/111 (EPSS) IEEE 1584Vendor PlatformsSEL WoodwardTest PhasesFactory Acceptance Test (FAT) Site Acceptance Test (SAT) Witness testing Staged commissioning / cutoverWhat Success Looks LikeFirst 90 DaysManaged energization safety on at least one active commissioning project — safety plans, LOTO, approach boundariesProduced a per-phase energization procedure with safety boundary diagrams accepted by project leadershipConducted daily safety briefings and pre-energization walkdowns for a commissioning crewFirst 180 DaysOwning energization safety across concurrent commissioning projects — setting safety standards and proceduresPPE category assignments verified against current arc-flash study results for all operating configurationsRecognized by commissioning crews and prime contractor teams as the safety authority for P&C commissioningRequired Background10+ years in electrical safety, commissioning, or field engineering on medium-voltage power systemsNFPA 70E expert-level knowledge: approach boundaries, PPE categories, energized work permits, LOTO managementArc-flash study interpretation per IEEE 1584 — incident energy, PPE assignments, approach boundary calculationsExperience managing concurrent energized and de-energized zones during staged commissioningEnergization procedure development for multi-source critical power (generators, ATS, UPS, switchgear)Safety plan coordination with site operations, safety personnel, and owner representativesPreferred BackgroundNETA Level IV certificationOSHA 30 or equivalent electrical safety certificationExperience at federal facilities, data centers, or mission-critical infrastructure with formal safety protocolsInternational commissioning experience (different local regulations alongside NFPA 70E)Arc-flash study development per IEEE 1584 (not just interpretation)What to Expect in the FieldTravel 60–80% during commissioning campaigns. Nationwide deployment with advance scheduling.Site Hours Off-hours energization windows (nights, weekends) when required by site operations. Presence required at every energization event.Customer-Facing Direct coordination with site safety, operations, and owner representatives. You are the safety authority during commissioning.Documentation Heavy — energization procedures, safety plans, LOTO documentation, approach boundary diagrams, qualified worker rosters, daily briefing recordsField Safety You define the safety program.

multi-source MVDirect access to the principal engineer who designed the protection system you are energizingHiring Process1ScreenBackground review against role requirements — vendor platform experience, relevant certifications, project types, and standards familiarity. Quick assessment of baseline alignment before investing either party's time.Resume review + 15-min intro call2Technical ReviewDeeper evaluation of technical depth. We review sample work — relay settings files, protection study reports, commissioning test procedures, or SCADA configuration packages — depending on the role. If samples aren't shareable, we discuss specific project scenarios in detail.Async work-sample review or 45-min technical call3InterviewScenario-based conversation with the principal engineer. Real project situations: how you'd approach a coordination study for a complex switchgear lineup, sequence a commissioning plan across multiple vendor platforms, or troubleshoot a protection scheme failure during site acceptance testing.60-min video call with founder4Exercise / Artifact ReviewA practical evaluation matched to the role. Engineering roles receive a take-home exercise — review and mark up a set of relay settings, identify gaps in a protection study, or develop a test procedure for a specific scheme. Field-focused roles walk through a commissioning package or test report they've delivered, explaining their methodology and decisions.Take-home exercise (2–4 hrs) or artifact walkthrough (60 min)5Final ConversationRole scope, current project pipeline, working arrangements, and compensation.
