Principal DC Power Installer (L4)

Overview The L4 Principal Installer is the ultimate authority on DC power deployment. You will oversee the most complex “Tier IV” installations, manage high-stakes brownfield retrofits, and serve as the final signatory for Quality Assurance (QA). Your role is to ensure that every installation, whether performed by internal teams or external contractors, meets the highest standards of safety, reliability, and engineering precision. Essential Duties and Responsibilities 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. High-Stakes Project Orchestration 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. Compliance & Forensic Audit 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. Leadership & Mentorship 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. Knowledge, Skills and Abilities Code Compliance: Expert knowledge of NEC, IEEE 1188/450, and NFPA 70E. Architecture: Deep understanding of how DC power interacts with AC UPS, ATS, and Generator systems. Risk Mitigation: Ability to perform "Live-Work" risk assessments and establish "Safe Work Zones" in high-density areas. Diagnostic Tools: Proficiency with Power Quality Analyzers, Infrared Thermography, and Battery Impedance testing. Education & Experience 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. Preferred Certifications RCDD (Registered Communications Distribution Designer) DCDC (Data Center Design Consultant) Expert-Level OEM Certifications OSHA 30 CPR Certification #J-18808-Ljbffr
