Job Description Summary
The UHP Gas Component Design & Development Engineer will lead the design, development, and validation of Ultra-High Purity (UHP) gas delivery components used in semiconductor and advanced manufacturing applications.
The role requires deep technical expertise in fluid mechanics, precision machining, electropolished (EP) components, and industry compliance (ISO, SEMI, ASME).
This position qualifies under Singapore's EP visa criteria, requiring advanced technical qualifications and specialized engineering experience.
Key Responsibilities
- Design and develop UHP-grade components - SMART pressure regulators, and SMART valves - ensuring electropolish (EP) compatibility, cleanliness, and long-term reliability.
- Perform 3D mechanical design and modelling using CAD software (SolidWorks, Creo) and simulation (FEA/CFD) for flow, pressure, and stress validation.
- Optimize flow path design for minimal particle generation and uniform flow characteristics in high-purity gas systems.
- Select and qualify materials (316L VIM-VAR, Hastelloy, etc.) meeting EP, SEMI, and ASTM standards.
- Define and execute qualification and reliability testing: leak rate, flow accuracy, endurance, thermal cycling, and surface roughness compliance (Ra 10 in).
- Collaborate with process, electronics, and control engineers to integrate sensors and flow control elements for test and certification
- Ensure compliance with SEMI F19/F57, ISO 8573, and ASME B31.3.
- Prepare and maintain detailed design documentation, including drawings, BOMs, test procedures, and reports.
- Coordinate with EP and BA tubing suppliers, cleanroom assembly teams, and QA for certification readiness.
- Support product qualification audits, failure analysis, and continuous improvement initiatives.
Specialized Skills
- Knowledge of EP/BA surface finishing standards, UHP material certification, and clean assembly procedures.
- Experience in semiconductor gas systems, test system development, or precision fluid control.
- Exposure to supplier qualification and quality management systems (ISO 9001).
- Strong analytical and problem-solving approach with hands-on testing experience.
Education / Experience / Languages
- Bachelor's or Master's degree in mechanical engineering, Mechatronics, Instrumentation, or related discipline from an accredited university.
- Minimum 5 years of relevant industry experience in UHP gas delivery component design or semiconductor equipment engineering.
- Proven expertise in UHP regulators, and valve mechanisms (concept to qualification).
- Proficient in SolidWorks/Creo and simulation tools (ANSYS, COMSOL, or CFD).
- Strong understanding of UHP component standards (ISO, SEMI, ASME) and EP process compatibility.
- Experience in cleanroom design, assembly validation, and leak testing (He leak rate 110 atm.cc/s preferred).
- Excellent communication skills and ability to work in cross-functional, multicultural teams.
