What we’re looking for

• You’ll need a proven track record installing, maintaining or troubleshooting complex technical equipment. Just as importantly, you’ll be confident working directly with customers, taking ownership, and managing competing priorities in a fast-moving technical environment.

• We DO need you to be ready and willing to travel internationally up to 60 percent of your time and often at short notice.

• We’re especially interested in experience with:

  • Semiconductor equipment or semiconductor manufacturing environments
  • Semiconductor metrology or process control systems
  • Scientific instruments or analytical systems
  • Optical, laser or photonics systems
  • Precision electromechanical equipment
  • Vacuum, automation or high-tech manufacturing systems

• You’ll be comfortable diagnosing faults across electrical, mechanical and software-controlled systems, and you’ll be willing and able to travel internationally on a regular basis.

Nice to have, not deal-breakers

• AFM, microscopy or metrology systems knowledge
• Lasers, optics or fibre-optic technologies
• Networking and software configuration skills
• High-voltage systems experience
• Scale-up or high-growth technology company experience

Qualifications

• A degree in Engineering, Physics or a related subject would be useful, but it’s not the only route in. We’re just as interested in equivalent experience gained through an apprenticeship, military service, field engineering or hands-on industry work. Demonstrated capability matters here.
