## About the role

End-to-End Tool Ownership: Manage an assigned section of back-end process tools (laser, cleaning, thermal, metrology, and material handling) to optimize tool availability, capability, and total cost of ownership. Advanced Troubleshooting: Serve as the final escalation point for complex electro-mechanical failures, using structured root-cause methods (8D, 5-Why) to improve MTBF and MTTR metrics under SEMI E10 standards.

## What they're looking for

- Education & Experience: Bachelor’s degree in Mechanical, Mechatronics, Electrical, or Manufacturing Engineering with 10+ years of hands-on equipment ownership in a high-volume semiconductor, advanced materials, or high-precision manufacturing environment
- Technical Depth: Mastery of electro-mechanical systems (motion control, PLC/HMI, pneumatics, vacuum, fluid delivery). Strong preference for experience with Class IV lasers, CMP/polishing, or robotic work cells
- Data-Driven Analysis: Track record of moving OEE, MTBF, and MTTR metrics with evidence rather than opinion. Experience with data analysis tools beyond spreadsheets (Python, JMP, SQL) is a plus
- Safety & Compliance: Practical experience applying machine safety codes (LOTO, NFPA 79, CE/UL, SEMI S2). Proficiency with 3D CAD (SolidWorks), PLM (Teamcenter), and CMMS frameworks
- Autonomy & Leadership: Proven history of operating independently as a principal contributor, managing competing priorities without close supervision, and aligning cross-functional teams without direct positional authority
- -Use appropriate PPE and follow all safety policies, practices, and procedures
