Commissioning & Field ExecutionNationwide (Field-Heavy)Hiring ENG IIIZA-35007Nationwide (Field-Heavy)Field-HeavyCompensation discussed during final conversationWhy This Role ExistsWe deliver P&C scopes that end with owner witness testing — the commissioning engineer is the person standing in front of the switchgear when the protection system has to prove it works. This role exists because the engineer who commissions the system should understand what the relay settings, automation logic, and mode sequencing are supposed to do. You execute L1–L5 commissioning on Tier III/IV data center power systems: FAT/SAT scripts, functional performance tests, staged cutovers, and witness testing across multi-vendor protection and controls equipment. Nationwide travel — you go where the projects are.What You OwnFAT/SAT/IST test procedures for protection relays, generator controllers, ATS, and SCADA systemsFunctional performance testing: protection scheme verification, trip coordination, interlock validationStaged commissioning planning: board-by-board or zone-by-zone cutover with deterministic rollbackTransfer testing: open-transition and closed-transition sequences, retransfer with time delayBlack-start drill execution and verification of automatic recovery sequencingPunch-list management through closeout and owner acceptanceTurnover packages: commissioning records, as-built documentation, O&M manualsSystems You'll TouchVendor PlatformsSEL Woodward CAT (Caterpillar) Omicron DobleSoftware ToolsAcSELerator QuickSet AcSELerator RTACStandardsNFPA 70E IEEE 1584Test PhasesFactory Acceptance Test (FAT) Site Acceptance Test (SAT) Secondary injection testing Functional performance testing Witness testing Staged commissioning / cutoverSite ActivitiesAutomatic mode transitions Automatic black-start sequencing ATS control (open/closed transition)What Success Looks LikeFirst 90 DaysCompleted commissioning or witness testing on at least one active project siteDeveloped FAT or SAT test procedures for a protection relay or controller scopeDemonstrated familiarity with the firm's commissioning documentation standards and turnover package requirementsFirst 180 DaysLeading commissioning execution on a data center project — writing test procedures, executing tests,

ABB — not locked into one OEM's equipment portfolioYour commissioning feedback improves the next design — direct loop between field reality and engineering officeSmall firm means your commissioning expertise directly shapes standards, procedures, and turnover qualityHiring 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.
