• Diagnose and rectify leaks, poor joints, misalignment and other manufacturing defects.
• Read and interpret engineering drawings, bills of materials and manufacturing instructions.
• Contribute to improvements in welding methods, assembly processes, tooling and product quality.

Essential Skills and Experience

• Practical experience in welding, soldering, brazing, precision assembly or mechanical fabrication.
• Good hand skills and the ability to carry out detailed, controlled work.
• Strong mechanical fitting and assembly capability.
• Experience using workshop hand tools, power tools and measuring equipment.
• Ability to read and work from engineering drawings.
• Ability to work accurately with small components and close-tolerance assemblies.
• A methodical approach to joint preparation, assembly and inspection.
• Willingness to learn specialist cryogenic and vacuum manufacturing processes.

Highly Desirable Skills

• TIG welding of stainless steel, particularly thin-wall tube and precision components.
• Soft soldering experience on copper and brass assemblies.
• Silver brazing or hard-soldering experience.
• Experience joining dissimilar metals.
• Tube fitting, tube bending and pipework fabrication experience.
• Experience with vacuum systems, cryogenic equipment, scientific instrumentation or high-vacuum components.
• Experience working in a precision engineering, aerospace, scientific, medical or specialist manufacturing environment.
• Comfortable working on both one-off and repeat production assemblies.
