(Sr.) Sustaining Product Design Engineer # 196298 (淡水廠，保障年薪14個月)

Your Job

We are seeking a proactive and experienced Senior Sustaining Mechanical Engineer to own and resolve mechanical product issues after new-product launch and mass-production release. This role serves as the technical focal point for sustaining engineering activities, working across design, manufacturing, quality, suppliers, project management, and customer-facing teams to protect product quality, supply continuity, cost, and customer satisfaction.

About the Role
This position focuses on post-launch mechanical engineering for liquid cooling solutions and related mechanical assemblies used in AI servers, data centers, and high-power electronics applications. The engineer will lead containment, root-cause analysis, corrective action, design or process improvement, qualification, and controlled implementation for field, factory, supplier, and customer issues. The role requires strong mechanical judgment, hands-on failure analysis, disciplined change control, and the ability to drive cross-functional issue closure without compromising safety, reliability, compliance, or traceability.

Our Team
Molex creates connections for life by enabling technologies that transform the future and improve lives. Our R&D and Product Development Engineering teams work with global manufacturing sites, suppliers, quality teams, and customers to sustain released products, improve manufacturability and reliability, and ensure robust execution from launch through the product lifecycle.

What You Will Do (Job Description)
Post-Launch Product Sustaining & Issue Ownership

• Own mechanical sustaining activities for newly launched and mass-produced products, including factory, supplier, qualification, customer, and field-return issues.
• Lead rapid containment, risk assessment, technical disposition, root-cause analysis, corrective action, and effectiveness verification.
• Prioritize issues based on customer impact, safety, reliability, shipment risk, recurrence risk, and production continuity.
• Maintain clear issue ownership, action plans, due dates, evidence, and closure criteria.

Mechanical Failure Analysis & Problem Solving

• Lead systematic failure analysis using 8D, 5 Why, Ishikawa, fault-tree analysis, DOE, tolerance analysis, and data-based verification.
• Analyze fit, function, assembly, dimensional, structural, thermal-mechanical, leakage, pressure, deformation, vibration, cosmetic, and reliability issues.
• Differentiate design-related, supplier-process, manufacturing-process, material, fixture, measurement-system, and handling causes.
• Define verification plans that prove root cause and confirm corrective-action effectiveness before closure.

Design, Drawing & Configuration Change Management

• Review and implement mechanical design changes, drawing revisions, tolerance updates, material changes, alternate-source changes, and cost-reduction improvements.
• Perform GD&T review, tolerance stack-up analysis, datum-strategy review, interface assessment, and design-for-assembly evaluation.
• Drive ECN/ECR, deviation, waiver, PCN, and controlled phase-in/phase-out activities with complete traceability.
• Assess backward compatibility, interchangeability, inventory impact, rework feasibility, tooling impact, and qualification scope.

Manufacturing & Supplier Support

• Partner with Manufacturing Engineering, Quality, SQE, suppliers, and factories to troubleshoot sustaining issues and improve yield, capability, and process stability.
• Lead supplier DFM reviews and corrective actions for CNC machining, stamping, plating, injection molding, LSR/rubber molding, brazing, welding, sealing, and assembly processes.
• Review PFMEA, Process Flow, Control Plan, work instructions, inspection methods, MSA, GR&R, Cpk/Ppk, and production validation evidence.
• Support alternate-source and plant-transfer qualifications to reduce supply risk and improve continuity.
