Introduction to the job

This role focuses on software‑oriented troubleshooting and problem-solving on PAS5500 / RH / YS systems—including stages, handlers, Illumination and all other module and system levels. 
Unlike traditional software development roles, this position centers on Linux-based control systems, C# / C++ control logic analysis, execution sequence, algorithm, motion behavior diagnostics, signal tracing, and system-level issue resolution. 

As a 3rd-line Production Engineer, you will proactively identify issues, define clear technical problem statements, and collaborate closely with D&E to drive structural fixes. 
Your daily work involves analyzing control logic behavior, IO interface anomalies, memory/communication issues, error tables, signal inconsistencies, and automation sequence problems to ensure stable factory operations and prevent repeat occurrences. 

This position is ideal for engineers who enjoy hands-on system debugging, motion/control problem analysis, and cross-functional technical collaboration, rather than full-time coding. 

Role and responsibilities

Software & Control Troubleshooting

• Diagnose and analyze issues within Linux-based control systems, including C# / C++ control logic, automation sequences, and motion behavior. 

• Perform signal tracing, log analysis, power/signal path checks, and interpret position/velocity/acceleration curves from motion control loops. 

• Identify root causes across software behavior, IO timing, memory patterns, PCB interactions, electrical noise, or mechanical coupling. 

3rd-Line Technical Problem Solving 

• Proactively identify production issues and define structured problem statements for D&E. 

• Support escalations and collaborate with D&E on MDEV / MTD investigations, engineering changes, and structural solutions. 

• Provide expert-level deep dives when 1st/2nd-line support has exhausted troubleshooting paths. 

Production Support & Structural Fixes

• Ensure stable factory execution for PAS5500 / RH / YS mechatronics modules. 

• Analyze error tables, software logs, automation sequences, and motion profiles to prevent repeat failures. 

• Drive data collection, experiment setup, validation of hypotheses, and structural improvement implementation. 

Documentation & Diagnostic Improvements

• Maintain, update, and optimize procedures, diagnostic methods, work instructions, and software/motion debugging guides. 

• Identify process gaps related to diagnostics or control behavior and create new procedures or sequences where needed. 

• Lead improvement projects and deliver measurable impact on factory stability and troubleshooting efficiency. 

Required Qualifications

Education

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, Information Systems, Electrical Engineering, Mechatronics, Automation, or related technical fields. 

Technical Skills

• Experience with Linux-based control systems. 

• Proficiency in C# and/or C++, especially for understanding and analyzing system control logic (not application-level coding). 

• Familiarity with:  Motion control fundamentals (position/velocity/acceleration loops) /Automation control theory /IO interfaces, communication protocols, and memorybehaviors /PCB basics, schematic reading, and signal/power tracing 

• Strong analytical and logical reasoning skills for root cause analysis. 

Problem-Solving

• Experience with system-level debugging, control logic analysis, or automation/machine troubleshooting. 

• Ability to translate ambiguous system symptoms into clear, structured technical problems.

Cross-functional Collaboration

• Ability to work closely with D&E, presenting technical findings and participating in deep-dive engineering discussions. 

• Capable of delivering technical presentations during interviews (topic assigned by hiring manager). 

Preferred Qualifications

• Experience with semiconductor equipment, precision motion systems, automation machinery, robotics, metrology, or stage control systems. 

• Familiarity with real-time control, EtherCAT, PLC interactions, embedded Linux, or automation controllers. 

• Hands-on experience with sensor/actuator integration or motion tuning. 

• Exposure to ECN, MDEV/MTD methods, or structured root cause analysis processes. 

• Ability to design controlled experiments and interpret complex logs to support structural fixes. 

This position requires access to controlled technology, as defined in the United States Export Administration Regulations (15 C.F.R. § 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.
