Essential Duties And Responsibilities 2. High-Stakes Project Orchestration 3. Compliance & Forensic Audit 4. Leadership & Mentorship
- Engineering & Design Validation
- Blueprint Scrubbing: Review engineered "Issued for Construction" (IFC) drawings to identify flaws in load calculations, cable pathing, or thermal management before equipment is unboxed.
- MOP Approval: You are the final reviewer of Methods of Procedure (MOPs) for Level 1-3 technicians. You must evaluate the risk of every "Hot Work" activity and provide contingency planning for worst-case scenarios.
- Standardization: Develop the "Gold Standard" for installation manuals, labeling schemes, and torque specifications used across the global data center fleet.
- Brownfield Retrofits: Lead the replacement of massive, live -48V DC plants while the data center is at full capacity, ensuring $N+1$ redundancy is maintained at every step.
- Vendor Management: Act as the primary technical point of contact for equipment OEMs (Vertiv, Schneider, Eltek) and third-party electrical contractors.
- Conflict Resolution: Resolve complex grounding loops or electromagnetic interference (EMI) issues that baffle lower-level technicians.
- Post-Mortem Analysis: Lead investigations into installation-related failures or "near-misses," providing the root-cause analysis (RCA) to the executive leadership.
- Final Commissioning (L5): Lead Integrated Systems Testing (IST), simulating total utility power loss to ensure DC plants and battery autonomy respond exactly as engineered.
- Training Program Development: Create the curriculum for L1-L3 training and perform the "practical" exams for technician promotions.
- Safety Advocacy: Serve as the "Stop Work Authority" on-site. If a process is unsafe or technically flawed, the L4 has the final word to halt operations, regardless of project deadlines.
- Code Compliance - Expert knowledge of NEC (National Electrical Code), IEEE 1188/450, and NFPA 70E. (Master)
- Architecture - Deep understanding of how DC power interacts with AC UPS, ATS, and Generator systems. (Expert)
- Risk Mitigation - Ability to perform "Live-Work" risk assessments and establish "Safe Work Zones" in high-density areas. (Expert)
- Diagnostic Tools - Proficiency with Power Quality Analyzers, Infrared Thermography, and Battery Impedance testing. (Master)
- Experience: 12+ years in DC power/Critical Facilities, with at least 5 years leading multi-million-dollar installation projects.
- Preferred Licensing: Master Electrician license or a bachelor's degree in electrical engineering.
- RCDD (Registered Communications Distribution Designer)
- DCDC (Data Center Design Consultant)
- Expert-Level OEM Certifications
- OSHA 30
- CPR Certification
