Technical Support Specialist — Applications

This role bridges Central Support and Applications from a US base — carrying applications expertise into the field, giving technical-sales engagements local engineering support, and acting as the coordination point that keeps Asia, UK and US aligned as the territory grows.

Key responsibilities

• Bridge CS and Applications: carry applications methods and know-how into field support and installs, closing the transfer gap that currently slows US delivery.
• Support technical sales locally: provide on-the-ground engineering backing to US technical-sales engagements, from demos to customer technical questions, without waiting on UK/Asia time zones.
• Coordinate cross-timezone information flow: act as the US anchor for Asia→UK→US coordination so support, applications and delivery information moves reliably rather than depending on one overloaded location.
• Deploy to customer sites: travel globally at short notice (60%) to support installs, upgrades and applications escalations where US or wider-team capacity is stretched.
• Shadow and up-skill: train on live builds and installs to reach lead-capable status, then contribute to standards and work instructions so knowledge is repeatable, not personal.
• Feed back into the product: channel field and applications findings back to NPI and engineering so recurring issues are designed out.

Required skills & experience

• Strong applications or field-engineering background in semiconductor capital equipment, metrology, or a closely related precision-instrument field.
• Hands-on experience supporting complex electro-optical or precision systems at customer sites (installs, upgrades, escalations).
• Able and willing to travel 60% globally, including short-notice deployment.
• US-based, with existing right to work in the United States.
• Excellent cross-functional communicator — comfortable working across engineering, applications, sales and multiple regional teams.
• Self-directed, able to operate as the local technical point of contact with limited on-site supervision.
• Right to work and live in the USA with the appropriate passport to allow international travel for work purposes

Nice to have

• Direct experience with 3D metrology or scanning-probe/RPM-class systems.
• Prior exposure to technical pre-sales or customer-facing applications work.
• Experience coordinating across Asia / Europe / US operations.
