Senior Mechanical Design Engineer

About the Position

The Senior Mechanical Design Engineer plays a critical role in the design and development of mechanical systems supporting mission-critical data center power distribution products, including low-voltage switchgear and switchboards. This role combines deep technical expertise with project leadership and mentorship to deliver high-performance, reliable, and manufacturable designs in a fast-paced, engineered-to-order environment.

Responsibilities

• Lead mechanical design of low-voltage switchgear and switchboard assemblies, including enclosures, structural frames, barriers, cable management, lifting provisions, ventilation, and service access.
• Develop 3D models, detailed drawings, and assemblies using SolidWorks; maintain complete manufacturing documentation packages including BOMs, fabrication drawings, and revision control.
• Support large-frame lineup configuration, shipping splits, installation interfaces, alignment, and maintainability for high-current systems (1200A–6000A class).
• Collaborate with Electrical Engineering to ensure mechanical layouts support bus, breakers, cable entry, metering, safety, and code compliance.
• Lead DFM and DFA activities, including modularization, standardization, part reuse, and reduction of custom components.
• Generate and manage Engineering Change Orders (ECOs), redlines, and deviation requests.
• Support prototype builds, factory acceptance testing, UL documentation, and certification activities (heat rise, dielectric, functional testing).
• Mentor junior and mid-level mechanical engineers through design reviews, technical guidance, and standard work.
• Partner with suppliers and fabricators on sheet metal, machining, welding, painting, gasketing, and assembly processes.
• Provide shop-floor support, participate in root-cause analysis, and drive corrective actions for build and quality issues.

Requirements

• Bachelor’s degree in Mechanical Engineering; Master’s degree preferred.
• 7+ years of experience in mechanical design within engineered-to-order, electrical infrastructure, or industrial product environments.
• Minimum 1–2 years of hands-on mechanical design experience for low-voltage switchgear or switchboards (1200A–6000A class preferred).
• Advanced proficiency in SolidWorks and PDM systems.
• Strong knowledge of sheet metal, machining, structural design, and tolerance control.
• Experience releasing complete manufacturing packages (drawings, BOMs, ECOs, revision control).
• Demonstrated ability to mentor engineers and lead technical execution across projects.
• Ability to read and interpret complex blueprints, schematics, and mechanical assemblies.

Preferred Qualifications

• Experience in data center power infrastructure or mission-critical electrical equipment.
• Background with switchgear OEMs or contract manufacturers.
• Familiarity with UL witness testing and certification documentation.
• Working knowledge of UL1062, UL891, NEC, and related safety and compliance standards.
