About the Job

Requirements

  • A bachelor's degree in Welding Engineering, Materials/Metallurgical Engineering, or Mechanical Engineering, or equivalent hands-on experience in lieu of a degree.
  • At least five years of welding engineering or weld quality experience in semiconductor capital equipment, ultra-high-purity gas systems, or a comparably regulated high-purity fabrication environment.
  • Demonstrated working knowledge of SEMI F78, F81, E49.8, and F70.
  • Hands-on or oversight experience with orbital gas tungsten arc welding equipment from Arc Machines Inc., Polysoude, Orbitalum, or comparable original equipment manufacturers, including weld schedule development and machine qualification.
  • Strong understanding of 316L stainless steel metallurgy, including electropolishing, sulfur content effects on weld penetration, inside-diameter surface finish, and passivation, as applied to ultra-high-purity gas line and chamber weldment fabrication.
  • Experience working within a certified cleanroom manufacturing environment (Class 100/ISO 5 or better), including contamination control protocols specific to gas panel and gas box assembly.
  • Familiarity with welding procedure specification and procedure qualification record development, and welder performance qualification under AWS D1.2, ASME Section IX, or equivalent codes adapted for orbital tube welding.
  • Working knowledge of VCR/VCO/face-seal fitting cleanliness requirements and ultra-high-purity component handling practices.
  • Root-cause and corrective-action problem-solving skills using 8D, fishbone, and 5-Why methods applied to weld defects and process escapes.

Responsibilities

  • Develop, qualify, and maintain welding procedure specifications and procedure qualification records for orbital gas tungsten arc welding of ultra-high-purity gas lines, gas panels, and chamber weldments.
  • Establish and audit welder/operator qualification programs for personnel performing orbital and manual welding on ultra-high-purity systems.
  • Serve as the site subject matter expert on applicable SEMI standards, including F78 for particle contamination and cleanroom compatibility, F81 for surface roughness for ultra-high-purity components, E49.8 for orbital weld documentation and acceptance, F70 for ultra-high-purity gas distribution system components, and related specifications governing gas delivery hardware.
  • Own weld quality within cleanroom fabrication cells, including gowning discipline, purge gas control, inside/outside-diameter surface finish verification, and contamination prevention throughout the weld process.
  • Perform and oversee visual, boroscopic, and dimensional weld inspections against acceptance criteria, and drive root-cause analysis and corrective action for weld discrepancies and nonconformances.
  • Provide metallurgical oversight of 316L stainless steel and related ultra-high-purity alloys, including heat-affected-zone control, oxide/heat-tint discoloration limits, interpass temperature, and purge gas/back-purge requirements to preserve corrosion resistance and surface passivation.
  • Specify, evaluate, and maintain orbital welding equipment—including power supplies, weld heads, and tube-preparation tooling—from manufacturers such as Arc Machines Inc., Polysoude, Orbitalum, or equivalent, including programming, preventive maintenance, and end-of-life qualification.
  • Partner with manufacturing engineering, quality assurance, and supply chain teams to qualify internal and supplier weld sources against consistent acceptance standards.
  • Support root-cause investigations and 8D/CAPA activities for weld-related field or customer escrow issues.
  • Maintain and audit weld travelers, certification records, and traceability documentation to support customer and internal quality audits.

Desired Qualifications

  • AWS Certified Welding Inspector (CWI) or equivalent certification.
  • Prior experience supporting supplier qualification or supplier weld audits for semiconductor equipment original equipment manufacturers or their supply base.
  • Experience with gas panel engineering documentation, mass flow controller/component-level failure mode and effects analysis, or ANSI/ASQ Z1.4 sampling plans in a quality context.
  • Familiarity with additional SEMI standards relevant to ultra-high-purity gas delivery, such as F19 and F57, and general semiconductor equipment quality systems.

About the Company

Applied Materials

Builds equipment for chip and display factories

Applied Materials designs and builds precision machines that chipmakers and display manufacturers use to form, shape and inspect thin layers of material. Its platforms handle steps such as depositing films and removing unwanted material, helping chipmakers create transistors and wiring at atomic scale. Customers include makers of logic chips and memory, as well as manufacturers of advanced displays. The company earns money from equipment sales, replacement parts and services, and factory software that schedules production and monitors manufacturing processes.
