Commissioning Engineer — Southeast

Commissioning & Field Execution

• Compensation discussed during final conversation

Why This Role Exists

The Southeast data center corridor — Virginia through Georgia — has the highest concentration of active hyperscale construction in the country. This role exists because commissioning delays on these projects carry real LD exposure, and flying engineers cross-country creates gaps between site visits that compound punch lists. You own L1–L5 commissioning on multi-vendor protection systems — design-through-acceptance, regionally anchored where the project density demands consistent presence.

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
• Punch-list management through closeout and owner acceptance
• Turnover packages: commissioning records, as-built documentation, O&M manuals

What Success Looks Like

First 90 Days

• Completed commissioning or witness testing on at least one Southeast data center project
• Developed FAT or SAT test procedures for a protection relay or controller scope
• Established working relationships with at least one prime contractor commissioning team in the region

First 180 Days

• Leading commissioning execution on Southeast corridor projects — owning the full commissioning scope
• Independently conducting witness testing with owner representatives present
• Known contact for prime contractors in the Southeast region for P&C commissioning needs

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 families)
• Woodward generator controller commissioning (easYgen 3400, LS-6)
• Experience working with AE/MEP/EPC prime contractors on data center projects
• Based in or willing to relocate to the Southeast (NC, VA, GA, TN, FL)

What to Expect in the Field

Travel 40–60% during commissioning phases. Regional focus — Southeast corridor (VA, NC, GA, TN, FL).

Site Hours Site hours during commissioning: early starts, occasional weekends. More predictable schedule with regional focus vs. nationwide travel.

Customer-Facing Direct interface with prime contractor commissioning leads and owner representatives. Regional relationships built over time.

Documentation Heavy — test procedures, commissioning records, punch lists, turnover packages

Field Safety NFPA 70E compliance mandatory — arc-flash PPE, approach boundaries, daily safety briefings

Why Ziggurat

• Regional focus means you build relationships with the primes building in the Southeast, not just pass through projects
• Commission what we designed — relay settings, automation logic, and coordination curves come from the same team
• Your field feedback improves the next design — direct loop between site reality and the engineering office
• Growing into the densest hyperscale construction corridor in the country

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.
