Role Overview:

We are seeking a Senior Mechanical Design Engineer (L3/L4) with strong expertise in the design and development of semiconductor equipment and Special Purpose Machines (SPM). This role

requires hands-on technical depth combined with design ownership, where the engineer will lead

concept development, detailed engineering, integration, validation, and provide guidance to junior

engineers while working closely with cross-functional teams.

Key Responsibilities:

• Own and execute conceptual, basic, and detailed mechanical design for semiconductor tools and SPMs.
• Perform basic engineering calculations related to strength, stiffness, thermal considerations, and sizing of mechanical components.
• Design structural frames, machine enclosures, and precision assemblies meeting performance and safety requirements.
• Apply dimensional stack-up and tolerance analysis to ensure functional assembly and precision.
• Demonstrate strong knowledge of engineering materials, surface treatments, and material compatibility for cleanroom and semiconductor environments.
• Design gas packaging enclosures, vacuum assemblies, and sealed systems, including inert gas purging (N₂) concepts.
• Apply expertise in seals and sealing technologies suitable for vacuum and controlled-atmosphere applications.
• Select and design conveyors, drives, and motion mechanisms using sound engineering practices.
• Support integration of mechanical systems with sensors, actuators, and automation hardware.
• Work with and integrate process and environmental sensors, including oxygen sensors, nitrogen flow control, temperature, clean dry air (CDA), and humidity sensors.
• Ensure proper routing, mounting, and serviceability of utilities within machine designs.
• Create and manage complex 3D models and large assemblies, ensuring clash-free integration with electrical and controls systems.
• Produce high-quality 2D drawings with GD&T and manufacturing notes, following drafting standards.
• Use simulation tools (FEA / CFD) to validate structural integrity, airflow, and thermal behavior, reducing physical iterations and development time.
• Prepare and maintain engineering documentation, BOMs, and change records.
• Work within PDM/PLM systems to manage revisions, configurations, and lifecycle data .
• Mentor and technically guide L1/L2 engineers, providing design reviews and best practices.
• Collaborate closely with electrical, controls, process, manufacturing, and suppliers.

Required Skills & Qualifications:

• Bachelor’s or master’s degree in mechanical engineering or related discipline.
• Strong expertise in structural design, materials, sealing systems, vacuum and gas-handling assemblies.
• Proficiency in 3D CAD tools (SolidWorks, NX, Creo, or equivalent) and drafting standards.
• Working knowledge of simulation tools for structural and CFD analysis.
• Strong analytical, problem-solving, and communication skills.

Good to Have:

• Experience in cleanroom / semiconductor tool design
• Knowledge of UL / CE compliance and industrial safety standards
• Exposure to DFMEA, tolerance stack-up tools, and design standardization
