Essential Duties and Responsibilities:

• Design and develop semiconductor test contactors, alignment frames, sockets, and plug-and-play interface solutions.

• Create detailed 3D models, assemblies, drawings, and engineering documentation using SolidWorks.

• Develop designs that meet customer requirements, manufacturability objectives, and reliability targets.

• Support new product introduction (NPI) activities from concept through production release.

• Perform tolerance analyses and mechanical stack-up studies for precision assemblies.

• Develop innovative solutions for complex semiconductor test applications.

Simulation and Analysis

• Perform structural, thermal, and motion analyses using SolidWorks Simulation and/or ANSYS.

• Evaluate product performance under production test conditions.

• Analyze design risks and implement corrective actions prior to release.

• Support failure analysis and root cause investigations.

Engineering Documentation and Configuration Control

• Generate and maintain engineering drawings, BOMs, specifications, and assembly documentation.

• Manage product data, revisions, and workflows using SolidWorks PDM.

• Support Engineering Change Orders (ECOs) and document control processes.

Manufacturing and Production Support

• Collaborate with manufacturing teams to resolve design and assembly issues.

• Support prototype builds, engineering evaluations, and qualification testing.

• Work with suppliers and internal stakeholders to improve quality, cost, and lead times.

• Implement Design for Manufacturability (DFM) and Design for Assembly (DFA) best practices.

Cross-Functional Collaboration

• Work directly with customers and internal teams to define design requirements.

• Participate in design reviews and technical discussions.

• Provide technical leadership and mentoring to junior engineers as needed.

• Communicate project status, risks, and recommendations effectively.

Systems and Process Improvement

• Support design automation initiatives using DriveWorks where applicable.

• Interface with Oracle ERP systems for engineering and product lifecycle processes.

• Contribute to continuous improvement activities and engineering best practices.

Required Qualifications: 

Technical Skills

• Expert-level proficiency in SolidWorks.

• Advanced experience with SolidWorks PDM.

• Experience supporting high-volume manufacturing environments.

Additional Qualification

• Demonstrated ability to work effectively in a fully remote environment with minimal supervision.

• Strong written and verbal communication skills for collaboration across geographically dispersed teams.

• Ability to manage multiple priorities and deliver results within aggressive project schedules.

Education and/or Experience: 

Education

• Bachelor’s degree in mechanical engineering or related engineering discipline required.

• Master's Degree preferred.

Experience

• 10 years of mechanical design engineering experience.

• 5 years of experience in semiconductor test, contactor, socket, alignment system, or related precision electromechanical product development.

• Demonstrated success leading complex engineering projects from concept through production release.

• Ability to become productive quickly and independently in a contract assignment environment.
