Principal Engineer, Low Voltage Switchgear Mechanical

About the role

Jabil is looking for a Principal Mechanical Design Engineer for low-voltage (LV) switchgear in Prince George, Virginia. The role is the senior technical authority for the mechanical architecture, design governance, validation strategy, industrialization and lifecycle support of LV switchgear and power distribution products, providing cross-program leadership and partnering with customers, manufacturing, sourcing, quality, regulatory, supplier and field support teams.

Key responsibilities

• Own and govern the mechanical architecture strategy for LV switchgear, switchboards, MCCs and power distribution equipment, translating requirements into engineering specifications, design rules, roadmaps and release deliverables.
• Lead mechanical architecture decisions for enclosures, busbar support, insulation interfaces, short-circuit resistant assemblies, interlocks, doors, hinges, latching mechanisms, seismic features and more.
• Define compartmentalization, equipment layout, accessibility, cable routing, heat-flow paths and serviceability requirements.
• Guide thermal engineering, including airflow, ventilation, heat dissipation analysis, CFD modeling, temperature-rise assessment and thermal validation.
• Set mechanical design criteria for structural integrity, GD&T, sheet metal, welding, bus interfaces, coatings, gaskets, ergonomics and assembly.
• Drive DFM, DFA, DFR, DfA, DFS and VAVE initiatives, and lead validation and qualification strategies (environmental, thermal, short-circuit, seismic, arc-flash, FAT).
• Support manufacturing readiness reviews, ramp issues, engineering change implementation and field troubleshooting.
• Mentor engineers, establish standards and design guides, and represent Jabil in customer technical reviews.

Required profile

• Bachelor's degree in Mechanical Engineering or a related field.
• 12+ years of mechanical engineering experience, including significant experience in LV switchgear, switchboards, MCCs or power distribution products.
• Demonstrated senior technical leadership across multiple NPI programs, platforms or product launches.
• Preferred: Master's degree, Lean/Six Sigma experience, and experience with global manufacturing transfers, production ramps and engineering changes.

Required skills

• Advanced CAD with Creo, SolidWorks, Inventor or equivalent, including complex assemblies and configuration management.
• Knowledge of UL 891, UL 1558, IEC 61439, NEMA, IEEE C37.20.1 and ANSI/IEEE switchgear standards.
• Tolerance stack-up, GD&T, welding design, sheet metal design for manufacturability, fastener strategy and structural integrity.
• FEA, CFD/thermal analysis, structural simulation and seismic design.
• PLM systems such as Windchill or equivalent.

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 and paid time off.
• Tuition reimbursement, life, AD&D and disability insurance, commuter benefits, pet insurance, adoption assistance and annual merit increases.
