Innovation, Efficiency and Ambition: this is what VAT has stood for over 50 years.
With this passion, VAT has grown to become the leading international developer, manufacturer and supplier of high-performance high-end vacuum valves and vacuum sealing technology, employing over 2000 people worldwide. The headquarters are located in Haag (Switzerland), the production centers in Switzerland, Malaysia, Romania and Taiwan.
Responsibilities:
Manage the welding program for vacuum component and chamber fabrication, ensuring compliance with AWS codes and UHV standards (e.g. AWS D18.1,SEMI F19, ASME Section IX). Oversee the development, qualification, and maintenance of Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), and welder certifications. Supervise manual MIG and orbital TIG welding operations, with a focus on achieving defect-free, full-penetration welds suitable for helium leak testing and vacuum integrity. Ensure all welding processes meet internal and customer cleanliness standards, including surface prep, post-weld cleaning, and weld discoloration limits. Collaborate with design, quality, and production teams to troubleshoot issues and support new product introductions (NPI). Responsible for control of production weld quality. Lead weld defect investigations and implement root cause corrective actions (RCCA) in accordance with ISO and customer-driven quality systems. Lead continuous improvement initiatives around weld consistency, process efficiency, and weld traceability. Assist with the tooling and fixturing designs required for weld/fit-up operation. Support or lead internal and customer audits related to welding and cleanliness documentation. Drive training and certification programs to ensure welder readiness, procedural discipline, and compliance with evolving customer requirements. Evaluate and maintain welding and purging equipment, ensuring readiness for high-mix, low-defect production. Requirements:
Degree in Welding Engineering or a related technical discipline AWS Certified Welding Inspector (CWI) or Certified Welding Educator (CWE) required. Lean manufacturing or Six Sigma certification a plus. 5–10 years of welding experience in precision stainless steel fabrication, with at least 3 years in a leadership or management role Strong knowledge of UHV/UHP welding principles, vacuum sealing techniques, and helium leak rate standards. Hands-on experience with TIG/MIG welding and clean fabrication best practices. Familiarity with vacuum standards and specifications (e.g., SEMI, ISO 14644, ASME). Excellent communication, documentation, and cross-functional collaboration skills. Experience working with OEM customers in semiconductor equipment, aerospace, or research lab environments. Knowledge of cleanroom protocols, vacuum-compatible materials, and surface finishing standards (e.g., electropolishing, passivation) Interested? We look forward to receive your application.
You can expect a dynamic and successful company where innovation, courage, fairness and transparency are encouraged and your ideas are welcome.
