About the Role

We are seeking an experienced Supplier Quality Engineer (SQE) specializing in chemical delivery and semiconductor fluid handling components. This role will focus on managing and developing suppliers across Korea and Japan, ensuring world‑class component quality, compliance with SEMI standards, and robust process controls for high‑purity chemical delivery systems.

The ideal candidate has deep technical knowledge of components such as mass flow controllers (MFCs), valves, pressure regulators, tubing/fittings, o‑rings, heaters, sensors, and ultra-high-purity (UHP) gas/chemical handling assemblies.

Key Responsibilities

Supplier Quality Management

• Own supplier qualification, performance monitoring, and continuous improvement for Korea- and Japan-based component suppliers.
• Conduct supplier audits, process assessments, and risk evaluations using industry standards (SEMI, ISO9001, IATF, etc.).
• Lead 8D, SCAR, containment, and root-cause investigations for supplier-caused quality issues.

• Evaluate and approve manufacturing processes for:
  • MFCs, valves, regulators, gas sticks
  • Heaters, sensors, filters, o‑rings, elastomers
  • Chemical delivery assemblies and UHP components
• Review supplier drawings, specifications, PFMEAs, control plans, and process capability data.
• Ensure cleanliness, leak integrity, and performance per SEMI standards (e.g., SEMI F20, F57, F38, F104, etc.).

• Support new product introduction (NPI) by collaborating with R&D, design engineering, and manufacturing engineering teams.
• Provide onsite technical leadership for supplier process improvements, equipment upgrades, yield improvements, and contamination reduction.
• Partner with internal quality, procurement, and operations teams to ensure flawless supplier execution.

• Ensure supplier manufacturing and materials are compliant with relevant SEMI, UHP, and high‑purity chemical delivery standards.
• Lead risk mitigation activities, including PCAs, FMEAs, MSA, and process capability improvement metrics.

• Bachelor's degree in Chemical Engineering, Mechanical Engineering, Materials Science, or related field.
• 5+ years experience in supplier quality, manufacturing engineering, or process engineering within semiconductor or high‑purity industries.
• Hands‑on experience with MFCs, valves, regulators, heaters, o‑rings/elastomers, or UHP fluid systems.
• Strong understanding of SEMI standards, cleanliness requirements, and contamination controls.
• Fluent Japanese (required) and professional English.
• Ability to travel frequently to suppliers across Korea and Japan.

• Experience working directly with Japanese suppliers (e.g., Horiba, Fujikin, CKD, KOFLOC, Nippon Seisen, etc.).
• Knowledge of chemical delivery modules, gas delivery systems, GC panels, or TIG-welded UHP assemblies.
• Competence in quality tools: 8D, SPC, MSA, APQP, PPAP, DOE, FMEA.
• Experience with supplier development and improving process robustness/throughput.
• Strong communication skills with cross‑cultural sensitivity.

• Up to 30%
