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,
