Principal Engineer, Medium Voltage Electrical

About the role

Jabil is looking for a Principal Electrical Engineer for medium voltage (MV) power distribution products and systems (1 kV to 38 kV) in Prince George, Virginia. The role is the senior technical authority for electrical architecture, design governance, validation strategy, industrialization and lifecycle support, providing cross-program leadership and guiding products from concept through production release.

Key responsibilities

• Govern the electrical architecture for MV switchgear, substations, transformers, feeder systems and power distribution equipment.
• Translate customer, regulatory, manufacturing and lifecycle requirements into engineering specifications, design rules, roadmaps and release deliverables.
• Lead decisions on protection, control, metering, power monitoring, communication networks and power distribution schemes.
• Approve protection and coordination philosophies, relay settings, arc-flash mitigation, grounding, insulation coordination, BIL requirements and system selectivity.
• Specify MV circuit breakers, vacuum interrupters, bus systems, protection relays, instrument transformers, surge arresters and grounding equipment.
• Define communication architectures using IEC 61850, Modbus RTU/TCP, DNP3, Ethernet/IP and other standards.
• Review short-circuit, coordination, arc-flash, load-flow, grounding and protection studies.
• Guide concept development, prototypes, pilot production, production release and post-launch support.
• Drive decisions on cost, performance, manufacturability, schedule, quality, reliability, serviceability and safety.
• Support manufacturing readiness reviews, ramp issues, engineering changes and design transfers across global sites.
• Ensure compliance with IEEE C37, ANSI C37, IEC 62271, NEC, NFPA 70E, NETA, UL and customer requirements.
• Represent Jabil in customer technical reviews and lead DFM, DFT, DFR, DFS and VAVE initiatives.
• Oversee validation and qualification strategies (dielectric, lightning impulse, BIL, temperature-rise, short-circuit, relay verification, FAT, SAT, arc-flash).
• Mentor engineers, develop standards, design guides and templates, and lead technical risk reviews and root-cause investigations.

Required profile

• Bachelor's degree in Electrical Engineering; Power Systems concentration preferred.
• 12+ years of electrical engineering experience, including significant experience in MV switchgear, substations, power distribution, renewable energy, utility or industrial power systems.
• Demonstrated senior technical leadership across multiple NPI programs, product platforms or product launches.
• Deep expertise in MV protection relays, relay coordination, insulation coordination, BIL, grounding, arc-flash mitigation, one-line diagrams, control schemes, metering and power system studies.
• Experience integrating IEDs, PLCs, HMIs, protection relays, power quality meters and automation systems in MV switchgear and substations.
• Experience integrating MV protection, metering, automation and monitoring with SCADA platforms.
• Knowledge of IEEE, ANSI, IEC, NEC, NFPA 70E, NETA, UL and utility standards.
• Preferred: PE license, Master's degree, experience with EMS, BMS, DCIM, microgrids, global manufacturing support, and Lean/Six Sigma.

Required skills

• ETAP, SKM PowerTools, EasyPower or equivalent power system analysis tools.
• Advanced EPLAN and/or AutoCAD Electrical.
• PLM systems such as Windchill.
• Familiarity with OSHA electrical safety, LOTO and electrical safe work practices.

What we offer

• Pay range of $126,100 - $227,000, with a performance-based short-term incentive.
• Medical, dental, prescription drug and vision insurance, 401K match, employee stock purchase plan, paid time off and tuition reimbursement.
• Life, AD&D and disability insurance, commuter benefits, pet insurance, adoption assistance and annual merit increases.
