Compensation discussed during final conversation
Why This Role Exists We 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 Own FAT/SAT/IST test procedures for protection relays, generator controllers, ATS, and SCADA systems
Functional performance testing: protection scheme verification, trip coordination, interlock validation
Staged commissioning planning: board-by-board or zone-by-zone cutover with deterministic rollback
Transfer testing: open-transition and closed-transition sequences, retransfer with time delay
Black-start drill execution and verification of automatic recovery sequencing
Punch-list management through closeout and owner acceptance
Turnover packages: commissioning records, as-built documentation, O&M; manuals
Systems You'll Touch Vendor Platforms
SEL Woodward CAT (Caterpillar) Omicron Doble
Software Tools
AcSELerator QuickSet AcSELerator RTAC
Standards
NFPA 70E IEEE 1584
Test Phases
Factory Acceptance Test (FAT) Site Acceptance Test (SAT) Secondary injection testing Functional performance testing Witness testing Staged commissioning / cutover
Site Activities Automatic mode transitions Automatic black-start sequencing ATS control (open/closed transition)
What Success Looks Like First 90 Days
Completed commissioning or witness testing on at least one active project site
Developed FAT or SAT test procedures for a protection relay or controller scope
Demonstrated familiarity with the firm's commissioning documentation standards and turnover package requirements
First 180 Days
Leading commissioning execution on a data center project — writing test procedures, executing tests, managing punch lists




Independently conducting witness testing sessions with owner representatives present
Contributing to staged cutover planning for live-site commissioning
Required Background 5+ years commissioning experience on medium-voltage critical power systems (data centers, substations, industrial)
FAT/SAT procedure development and execution for protection relays and generator controllers
Secondary injection testing with Omicron or Doble test sets
Transfer testing experience: ATS open/closed transition, generator paralleling, load bank testing
NFPA 70E compliance: arc-flash PPE, approach boundaries, LOTO procedures on energized equipment
Punch-list management and turnover documentation experience
Preferred Background NETA Level III or IV certification
SEL relay commissioning (QuickSet, 751/700G/2440 families)
Woodward generator controller commissioning (easYgen 3400, LS-6, DTSC-200)
Staged commissioning on live critical infrastructure with rollback planning
IEC 61850 GOOSE verification and PRP network failover testing
What to Expect in the Field Travel 60–80% during active commissioning. Nationwide deployment — you go where the projects are.
Site Hours Site hours during commissioning phases: early starts, weekend milestones, off-hours energization windows. Adaptable between projects.
Customer-Facing Direct interface with prime contractor commissioning leads, owner witness testing coordinators, and site safety personnel
Documentation Heavy — test procedures, commissioning records, punch lists, as-built documentation, turnover packages
Field Safety NFPA 70E compliance mandatory — arc-flash PPE (Cat 2+ typical for MV), approach boundaries, daily safety briefings, LOTO management
Why Ziggurat You commission what we designed — the relay settings, the automation logic, the coordination curves all come from the same firm
Multi-vendor commissioning: SEL, Woodward, CAT, ABB — not locked into one OEM's equipment portfolio
Your commissioning feedback improves the next design — direct loop between field reality and engineering office




Small firm means your commissioning expertise directly shapes standards, procedures, and turnover quality
Hiring Process 1
Screen
Background 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 call
2
Technical Review
Deeper 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 call
3
Interview
Scenario-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 founder
4
Exercise / Artifact Review
A 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)
5
Final Conversation
Role scope, current project pipeline, working arrangements, and compensation. This is a two-way conversation — we want to confirm the role fits your goals, not just the other way around.
30-min call
This role supports our testing commissioning and end to end service scopes.
