Job Description/Preferred Qualifications

We are looking for a highly skilled hands-on engineer with experience supporting and troubleshooting complex semiconductor capital equipment in a fab environment. This role is ideal for someone who enjoys working directly with tools in the field, diagnosing issues at the system and component level, and driving solutions that keep production running.

As a Customer Support Engineer, you will be the technical expert on-site-partnering closely with customers to resolve equipment issues, optimize performance, and minimize downtime in a cleanroom manufacturing environment.

What You'll Do

• Troubleshoot and repair advanced semiconductor equipment at customer sites, including both system-level and board/component-level diagnostics
• Perform root cause analysis on complex electro-mechanical, vacuum, chemical, and process-related issues
• Work hands-on to restore tool performance quickly and safely, minimizing fab downtime
• Evaluate equipment behavior and identify issues that may stem from process conditions (e.g., contamination, leaks, or environmental factors)
• Make critical decisions in the field, including recommending tool shutdowns for safety or yield protection when needed
• Support installations, upgrades, and modifications of equipment in partnership with installation teams
• Document service activity, recurring issues, and corrective actions to support continuous improvement
• Manage spare parts inventory and support service-related administrative tasks (reports, quotes, etc.)
• Collaborate with engineering teams to share knowledge and improve service strategies
• Provide technical guidance to peers and assist with cross-training as needed

What This Role Looks Like

• Significant time working on the factory floor or in cleanroom environments (50%+ travel/on-site)
• Independent, field-based role requiring strong problem-solving and ownership mindset
• Daily communication with internal teams during critical situations (especially tool-down events)
• Work that goes beyond scripts or standard procedures-requiring real-time troubleshooting, technical judgment, and hands-on expertise

What We're Looking For

• 5+ years of experience supporting semiconductor capital equipment (or similarly complex manufacturing equipment)
• Proven ability in hands-on troubleshooting of electro-mechanical systems (not IT/software support)
• Experience working in cleanroom/fab environments strongly preferred
• Strong understanding of system-level diagnostics, not just component swaps
• Ability to work independently under pressure and solve complex, non-routine problems

Why This Role Stands Out

This is not an IT support or help desk role. It's a true field engineering position where you'll apply your technical expertise to solve complex equipment challenges, work directly on advanced tools, and play a critical role in keeping semiconductor manufacturing running.
