Job's mission

As a Principal Mechanical Engineer, you will be a technical leader in the design and development of complex mechanical systems for semiconductor capital equipment. You will architect and integrate high-precision modules - spanning vacuum systems, wafer handling robotics, gas delivery, and thermal assemblies - while mentoring teams and driving innovation across the product lifecycle. This role is ideal for a seasoned engineer with deep technical expertise, a systems-level mindset, and a passion for solving complex, multidisciplinary challenges.

What you will be working on

• Driving reactor development, and optimization of semiconductor processing equipment, with focus on design for oxidation, annealing, curing, atomic layer deposition (ALD), and chemical vapor deposition (CVD) techniques for thin films
• Lead the design and integration of mechanical, electrical, and pneumatic subsystems for deposition and thermal processing equipment.
• Architect system-level solutions that balance performance, reliability, manufacturability, and cost.
• Drive design-for-manufacturing (DFM) and design-for-assembly (DFA) principles across the product lifecycle.
• Apply advanced simulation techniques (FEA, CFD, thermal, multiphysics) to validate and optimize designs.
• Collaborate with cross-functional teams (controls, process, electrical, supply chain) to ensure seamless system integration.
• Guide the creation of master BOMs, configuration management, and high-quality documentation.
• Lead root cause analysis and implement corrective actions using structured problem-solving methodologies (8D, 5 Whys, DoE).
• Creating technical innovations, delivering creative solutions, and contributing to ASM’s IP portfolio through invention disclosures and patents
• Mentor junior engineers and provide technical leadership across global teams.
• Represent ASM in customer escalations, technical reviews, and innovation initiatives.

What we are looking for

• Master’s degree in Mechanical Engineering (PhD is also welcome) with at least 8 years of experience in complex mechanical design
• Proven expertise in any of the following:
  • Wafer handling systems (robotics, chucks)
  • Vacuum and gas delivery systems
  • Thermal and structural analysis
  • Pneumatic control systems
  • Material selection and surface treatments
• Proficiency in CAD tools (e.g., Creo, SolidWorks, Inventor) and simulation tools (ANSYS, COMSOL, etc.).
• Deep understanding of semiconductor manufacturing workflows, process-material interactions, and cleanroom standards.
• Strong communication skills and the ability to lead technical discussions with internal and external stakeholders.
• Experience with PLM systems, configuration control, and global product development.

Preferred qualifications 

• Experience with HALT/HASS, reliability engineering, and cost-of-consumables (CoC) optimization.
• Familiarity with SEM, TEM, FTIR, QCM, and other metrology tools.
• Knowledge of SEMIF47, UL, CE, and other industry standards.

What sets you apart

• Experience with advanced manufacturing techniques or materials science.
• Knowledge of industry-specific standards, regulations, and processes.
• A passion for driving innovation and improving processes.
