The Principal Mechanical Design Engineer – Low Voltage (LV) Switchgear serves as the senior technical authority for the mechanical architecture, design governance, validation strategy, industrialization, and lifecycle support of low-voltage switch gear and power distribution products. This role provides cross-program technical leadership, establishes mechanical engineering standards and design practices, resolves complex technical risks, and guides product decisions from concept through production release.

The Principal Engineer partners with customers, global engineering teams, manufacturing, sourcing, quality, regulatory, suppliers, and field support organizations to ensure solutions meet customer requirements, manufacturing capabilities, safety expectations, quality objectives, cost targets, and Jabil product lifecycle processes.

• Own and govern the mechanical architecture strategy for LV switch gear, switchboards, MCCs, and power distribution equipment across assigned programs, platforms, or product families.
• Translate customer, regulatory, manufacturing, and lifecycle requirements into scalable engineering specifications, design rules, technical roadmaps, and release deliverables.
• Lead system-level mechanical architecture decisions for enclosure systems, structural assemblies, busbar support systems, insulation interfaces, short-circuit resistant mechanical assemblies, mechanical interlocks, doors, hinges, latching mechanisms, seismic features, and associated switch gear mechanical hardware to achieve safety, reliability, manufacturability, and serviceability objectives.
• Contribute to overall system architecture and own mechanical definition of compartmentalization strategies, equipment layouts, accessibility, maintainability, cable routing concepts, heat-flow paths, service access, and installation/serviceability requirements in alignment with safety and operational objectives.
• Provide technical direction for thermal engineering activities including airflow design, ventilation strategies, heat dissipation analysis, CFD modeling, temperature-rise assessment, thermal margin strategy, and thermal validation testing.
• Define and govern mechanical design criteria for structural integrity, tolerance management, GD&T, sheet metal design, welding design, copper bus interfaces, hardware selection, coatings, gasketing, sealing, ergonomics, and assembly/service access.
• Guide concept development, prototype builds, design verification, pilot production, production release, and post-launch engineering support activities across multiple programs.
• Drive critical engineering decisions that optimize product cost, performance, manufacturability, schedule, quality, reliability, serviceability, safety, and long-term platform reuse.
• Establish design transfer expectations, support manufacturing readiness reviews, resolve production ramp issues, and guide engineering change implementation across global manufacturing sites.
• Ensure compliance with applicable standards and requirements including UL 891, UL 1558, NEC, IEC 61439, NEMA, IEEE C37.20.1, ANSI/IEEE switch gear standards, seismic requirements, and customer-specific specifications.
• Serve as the senior LV switch gear mechanical engineering representative for customer technical reviews, architecture discussions, issue resolution, and product development decisions.
• Lead Design for Manufacturing (DFM), Design for Assembly (DFA), Design for Reliability (DFR), Design for Automation (DfA), Design for Serviceability (DFS), and Value Analysis/Value Engineering (VAVE) initiatives.
• Define and oversee mechanical validation and qualification strategies including environmental, thermal, short-circuit, seismic, arc-flash, enclosure integrity, safety, customer witness testing, and FAT evaluations.
• Provide expert support for field troubleshooting, corrective actions, production issues, supplier technical issues, and complex field issue resolution activities.
• Lead high-impact technical risk reviews, root-cause investigations, corrective actions, design governance reviews, and continuous improvement initiatives.
• Mentor engineers, review critical technical deliverables, and develop reusable standards, design guides, checklists, templates, and best practices for LV switch gear mechanical engineering execution.
• Collaborate with global engineering, manufacturing, sourcing, quality, regulatory, suppliers, and customer teams to align technical decisions with…
