Senior / Mechanical Design Engineer (R&D)

Responsibilities:

Perform mechanical design of precision components, subsystem/system to support the development of the next generation semiconductor metrology equipment.

Own and drive the mechanical design process:

• Gather and uncover technical requirements and translate them into subsystem specifications.
• Conduct preliminary feasibility studies through engineering first principles and/or experiments.
• Propose and complete the design from conceptual design, detailed design to detailed drawings.
• Conduct analysis and simulations, including structural, thermal, vibration/modal Finite Element Analyses (FEAs).
• Participate and lead design reviews to obtain a peer-oriented design assessment.

Plan and execute design verification/validation:

• Fit/form test on sub-assembly/system, which includes hands-on work in the cleanroom building/assembling the first few mechanical assemblies.
• Perform risk analysis, develop test plans with well defined test criteria, and execute verification testing of subsystems and systems.

Supplier management:

• Ensure all design requirements are appropriately specified and parts quality meets specifications with inspection on incoming components.
• Collaborations for customized solutions when required.
• Manufacturing process transfer and qualification.

Cross collaboration:

• Present technical data effectively to diverse audiences in design reviews, status updates, and issues.
• Collaborate with multi-functional engineering teams, including electrical engineers, software engineers, systems engineers, and manufacturing/service engineers, to ensure seamless integration and testing at both subsystem and system levels.
• Develop and release comprehensive documentation of designs, such as assembly and test procedures. Provide training on the new design/procedure and transfer to manufacturing.

Tool maintenance and troubleshooting:

• Apply standard problem-solving methods to identify root causes of sub-system and system test failures.
• Collaborate with manufacturing team during product ramp-up to support and troubleshoot product issues.

Requirements:

• In-depth understanding of mechanical engineering fundamentals, encompassing design principles, materials selection, Geometric Dimensioning and Tolerancing (GD&T), tolerance stack-up analysis and error budgeting.
• Strong mechanical engineering fundamentals, including design principles, machine elements, materials, fabrication methods.
• Experience in several of these areas is desirable: opto-mechanical design, precision mechanism, vibration isolation and damping, flexure and compliant mechanism, structural optimization, tooling and test fixture design, design with carbon fiber composite, elastomers, high performance plastic material, design for cleanliness, motion stage design, temperature control design.
• Familiar with mechanical manufacturing processes including machining, sheet metal fabrication, welding, etc.
• Proficient in 3D solid modeling using CAD, preferably ProE/Creo.
• Basic knowledge in simulation software (eg. Solidworks, Creo, ANSYS, etc), capable of structural, vibration, thermal and fluid simulation. Able to do first order estimation using mathematics.

Desired attributes:

• Demonstrate perseverance and drive to be better in solving complex problems.
• Excellent team player and contribute to team effort to accomplish overall objectives as needed.
• Be flexible and adaptive to adjust project focus based on priority changes.
• Excellent communication and interpersonal skills, capable of growing in a collaborative, dynamic environment.

Minimum Qualifications:

• Doctorate (Academic) Degree and 0 years related work experience; Master's Level Degree and related work experience of 3 years; Bachelor's Level Degree and related work experience of 5 years
