Gathers and reviews data Northrop Grumman Weapons Systems is currently seeking Principal Electrical Facilities Engineer 3 or Sr. Principal Electrical Facilities Engineer 4 for our Elkton, Maryland location.

The Northrop Grumman Propulsion Systems and Controls (PS&C) facility in Elkton, Maryland began solid-propellant rocket operations in 1948. Today, the Elkton PS&C facility designs, develops, and produces solid-propellant propulsion and ordnance systems in programs professionally managed for a wide variety of Government and commercial customers.

The facility also serves as the hub for offsite engineering and test facilities in Ronkonkoma, NY, Palm Beach Gardens, FL and San Jose, CA.

Job Summary

As Principal Electrical Facilities Engineer 3 or Sr. Principal Electrical Facilities Engineer 4, you will be the primary technical lead for the design, operation, and optimization of electrical power and distribution systems across the Elkton propulsion campus.

You will ensure that all electrical infrastructure—ranging from utility service entrances, substations, and motor control centers to building power, lighting, and specialized process loads—operates safely, reliably, and efficiently while meeting the demanding requirements of energetic manufacturing, test, and R&D environments.

You will blend hands-on electrical engineering, strategic project management, and cross-functional collaboration to:

• Lead capital project delivery for electrical systems from concept through closeout.
• Design, upgrade, and troubleshoot electrical distribution and protection schemes for industrial and high-hazard facilities.
• Champion electrical reliability, energy performance, and regulatory compliance.
• Support other facility disciplines (mechanical, controls, civil/structural) as needed to deliver integrated solutions.

You will be part of a high-performing facilities team in accordance with Northrop Grumman’s Leadership Values.

Core Technical Responsibilities:

• Planning, Design & Technical Leadership – Electrical Focus
• Lead the end-to-end planning, detailed design, and supervision of electrical power systems, including utility feeders, substations, switchgear, motor control centers (MCCs), panelboards, transformers, grounding systems, and lighting.
• Develop and maintain electrical single-line diagrams, load lists, panel schedules, and protective device coordination studies for plant-wide electrical distribution.
• Perform load calculations, short-circuit analyses, arc-flash studies, and protective relaying design in accordance with NFPA 70 (NEC), NFPA 70E, IEEE, and applicable DoD and corporate standards.
• Design and optimize electrical systems that support HVAC, process equipment, test cells, and building services; ensure adequate capacity, reliability, and maintainability.
• Partner with architecture, engineering firms, and internal stakeholders to integrate electrical requirements into multidisciplinary facility designs, ensuring alignment with safety, HAZOP/HOPs, and regulatory requirements.
• Provide technical leadership on electrical design standards, equipment selection, and installation practices; participate in peer reviews of electrical design documents and contractor submittals.
• Data Collection & Requirements Analysis & System Studies
• Compile and analyze equipment specifications, electrical nameplate data, and utility information to determine power requirements and distribution strategies.
• Develop electrical basis-of-design documents and requirements for new buildings, process lines, and test facilities, aligning with HAZOP/HOPs, DoD 4145.26, project schedule, and construction feasibility.
• Conduct power quality assessments (harmonics, voltage flicker, transients) and recommend mitigation strategies (filters, capacitors, UPS systems, etc.) to protect sensitive loads.
• Translate analyzed data into clear electrical requirements that drive design, procurement, and execution phases.
• Procurement, Contract Management & Vendor Coordination
• Prepare electrical-focused bid packages, scopes of work, and technical specifications for construction, installation, and service contracts involving electrical systems.
• Develop detailed electrical cost estimates for equipment, installation, labor, materials, and commissioning activities.
• Prequalify vendors and contractors for electrical work; issue RFPs, evaluate bids, negotiate contracts, and monitor performance against SLAs and technical deliverables.
• Manage electrical project schedules, budgets, and change orders, ensuring that scope changes and risks are properly documented and communicated.
• Construction, Installation Supervision & Field Engineering
• Oversee and inspect electrical construction and equipment installations to verify strict compliance with drawings, specifications, codes, and project schedules.
• Provide on-site engineering support during installation, startup, and commissioning, including resolution of field issues, RFIs, and design clarifications.
• Conduct site inspections and punch-list walkdowns, ensuring that electrical systems are installed, labeled, tested, and documented per requirements.
• Verify proper implementation of grounding, bonding, and overcurrent protection schemes and ensure that equipment clearances, working spaces, and access meet safety standards.
• Equipment Qualification, Operations & Maintenance Support
• Plan and oversee qualification and performance verification of newly installed electrical equipment—factory acceptance tests (FAT), site acceptance tests (SAT), functional tests, and reliability run-offs.
• Support preventive and predictive maintenance programs for electrical assets using the CMMS; define work-order strategies and integrate condition monitoring data (e.g., IR scans, insulation resistance, breaker testing).
• Conduct FMEAs and reliability-centered maintenance (RCM) analyses for critical electrical assets to maximize uptime and reduce failure risk.
• Provide technical guidance on electrical troubleshooting, fault diagnosis, and corrective actions for facility systems.
• Energy Management & Sustainability
• Participate in energy-management initiatives focused on electrical systems: submetering, LED retrofits, high-efficiency transformers, VFD deployment, and optimization of demand and power factor.
• Analyze electrical energy consumption data to identify savings opportunities and support renewable energy or resilient power projects (e.g., solar, backup generators, microgrids) where appropriate.
• Design electrical solutions with sustainability, total cost of ownership, and lifecycle performance in mind.
• Compliance, Safety & Stakeholder Management
• Ensure full compliance with OSHA, NFPA, NEC, NFPA 70E, HOPs/HAZOPs, PSM, local building codes, and environmental regulations relevant to electrical facilities.
• Lead or support electrical safety
