Principal Systems/Mechanical Design Engineer, Semiconductor

Join a highly innovative engineering organization building next‑generation semiconductor capital equipment components and sub-assemblies. As a Principal Systems/Mechanical Engineer, you will analyze, improve, and define subsystem architectures that directly influence system performance, throughput, and reliability for customers at the forefront of semiconductor equipment manufacturing. • We are seeking a highly skilled Principal Systems/Mechanical Engineer, Semiconductor to lead the design and integration of complex subsystems used in advanced semiconductor capital equipment. • You will architect mechanical, thermal, fluid, and structural solutions that drive system performance and reliability, working closely with customers and cross‑functional teams across the full product lifecycle. • This is a high‑impact technical leadership role with significant influence over subsystem architecture, innovation, and customer success. What will you do? This role partners with the business unit, world-class customers, engineering centers, operational sites, and strategic suppliers globally to solve complex multidisciplinary design, manufacturing, and supply chain challenges. Specific examples include: Co-Innovation Through Subsystem Architecture & Design • Analyze, refine, architect and design mechanical subsystems including robotics/mechatronics, vacuum and gas delivery, power systems, and precision mechanical assemblies. • Develop detailed CAD models and engineering drawings for weldments, sheet metal, machined parts, and assemblies. • Analyze, refine, and define system and subsystem interfaces, requirements, and specifications. • Develop and maintain interface control documents (ICDs). • Lead requirements decomposition and ensure bi-directional traceability. • Establish subsystem validation strategies and verification plans. Analysis & Verification • Perform structural, thermal, dynamic, and vacuum-related analyses using advanced FEA tools. • Lead risk assessments including FMEAs, root cause analysis, and structured problem‑solving. • Validate system reliability through load‑path evaluation, stress analysis, fatigue modeling, and environmental considerations. Technical Leadership & Cross‑Functional Integration • Lead cross‑functional design reviews and drive subsystem integration, optimization, and design validation. • Collaborate with global teams, suppliers, and customers to refine requirements and resolve technical issues. • Champion DFX, VAVE, Lean methodologies, and continuous improvement initiatives. • Mentor early‑career engineers, elevate technical standards, and influence engineering culture by role modeling key attributes of leadership and ownership. • Make high-impact technical decisions that influence product performance and industry competitiveness. • Represent engineering in customer engagements and roadmap discussions. Lifecycle, Compliance & Supply Chain Support • Support NPI, RFQ processes, qualification testing, and component lifecycle management. • Ensure design compliance with global regulatory standards (UL, CE, RoHS, REACH). • Develop and maintain robust documentation including BOMs, specifications, test plans, qual plans, and ECOs. • Partner with product management, operations, supply chain, and finance to ensure solutions meet cost, reliability, and schedule targets. How will you get here? Required • Bachelor’s degree in mechanical, systems, or related engineering field. • 5+ years experience in semiconductor capital equipment or wafer‑fab, advanced packaging environments. • Expertise in mechanical design, precision systems engineering, mechatronics, power systems, and fluid/vacuum systems. • Proficiency in FEA, CAD, and structural/thermal analysis tools. • Strong communication, documentation, and cross‑functional collaboration skills. • Demonstrated ability to lead reviews, guide teams, and interface with customers. • Ability to travel domestically and internationally up to 30%. Preferred • MS in mechanical or systems engineering • Experience in semiconductor mechanical system design • Hands‑on prototyping and global supplier engagement
