About the role: 

The role is ideal for an engineer with a strong background in high value complex microscopy instrumentation and precise motion control environments, who enjoys solving complex multidisciplinary problems in advanced semiconductor equipment.

A typical day for a Technical Support Specialist (Control Systems) could look like this:

 Control Systems Technical Support

• Providing advanced troubleshooting and diagnostic support for control system issues across installed Metron3D systems and manufacturing builds


• Acting as a trusted technical escalation point for Customer Support, Field Service, and Applications teams on software–hardware integration topics


• Investigating issues across motion control, sensors, feedback loops, and system automation


• Supporting the fast, effective resolution of high‑impact field issues affecting system performance

Motion Control & Precision Systems

• Analysing and troubleshooting closed‑loop control systems and feedback performance


• Working hands‑on with high‑precision sensors, encoders, and motion control components

Automation & Equipment Integration

• Supporting control system integration with semiconductor automation equipment, including EFEM interfaces and wafer‑handling robotics


• Ensuring stable communication, timing, and coordination across system components

System‑Level Diagnostics

• Working closely with the Technical Support Specialist (Hardware)  and Customer Support Team to understand interactions between control software and hardware


• Reviewing system logs, control data, and diagnostics to identify root causes of instability or performance drift


• Producing clear, structured reports for both engineering and management audiences

Root Cause Analysis & Corrective Actions

• Identifying design, configuration, or process improvements to prevent recurring issues


• Supporting engineering teams in improving control system architecture and robustness


• Capturing lessons learned from field issues and feeding them back into internal knowledge bases

Technical Knowledge Development

• Developing and maintaining troubleshooting guides, diagnostic workflows, and technical documentation


• Supporting internal training for Customer Support, Applications, and Manufacturing teams

Cross‑Functional Support

• Taking part in cross‑functional technical and operational discussions to strengthen system‑level thinking


• Supporting User Acceptance Testing and wider product testing activities


• Collaborating with the Software team to support smooth and reliable software releases

Who we are looking for:

To succeed as a Technical Support Specialist (Control Systems), we do need you to have the following experience or skills:

• Understanding of precision electromechanical and motion control systems
