Coop - Mechatronics Engineer (Internship)

ASML • Wilton, CT

5d • Onsite

About The Position

The DUV Reticle Stage IBS MDU team supports engineering activities for the reticle stage, a precision mechatronic subsystem in ASML’s DUV lithography systems. The team uses MATLAB-based analysis tools to assess system dynamics and performance from measurement data. ASML is seeking a co-op student interested in mechatronics, data analysis, signal processing, and software development to help evolve these tools.

The primary assignment is to develop and improve MATLAB-based tools for analyzing and visualizing DUV Reticle Stage dynamic performance, particularly power spectral density (PSD) and frequency-domain analysis. The co-op will work with experienced mechatronics engineers to understand existing methods, gather requirements, implement improvements, and validate results against existing engineering analyses. The work includes investigating existing code, documentation, and datasets; collaborating with subject-matter experts; and improving the usability and documentation of the tools.

This is an on-site position in Wilton, Connecticut, with in-person attendance required for work-related events, trainings, and meetings. The student must be available for a 6- to 9-month assignment; the education and experience section specifies availability for a 6-month co-op assignment. The role is intended for a college junior or senior pursuing a bachelor’s degree in a relevant engineering field.

Requirements

• Be a college junior or senior pursuing a bachelor’s degree in Mechanical Engineering, Mechatronics, Electrical Engineering, Controls Engineering, Robotics, or a related engineering field.
• Be available for a 6-month co-op assignment; the position description also states that candidates must be available for 6 to 9 months.
• Have experience programming in MATLAB through coursework, projects, research, or previous internships or co-ops.
• Understand fundamental mechanical dynamics and vibrations.
• Be familiar with signal processing and frequency-domain analysis, such as Fourier transforms, frequency response, or power spectral density.
• Be able to work with experimental or measurement datasets and create clear engineering plots and visualizations.
• Use a structured approach to testing and validating computational results.
• Show curiosity and willingness to investigate unfamiliar technical problems.
• Be comfortable approaching engineers, asking questions, and gathering information from multiple subject-matter experts.
• Be able to turn loosely documented requirements into a structured engineering solution.
• Have strong problem-solving skills and attention to detail, particularly when validating numerical results.
• Be able to work independently while seeking feedback and collaborating with an engineering team.
• Have clear written and verbal communication skills, including the ability to document technical work for future users.
• Be legally authorized to access controlled technology before beginning work.

Nice To Haves

• Familiarity with Git, SVN, or another version-control system.

Responsibilities

• Develop and update MATLAB tools for analyzing and visualizing Reticle Stage dynamic performance data, particularly PSD and frequency-domain analysis.
• Review MATLAB code, available documentation, and example datasets to understand existing analysis tools and methods.
• Collaborate with and interview mechatronics engineers to gather requirements and uncover engineering knowledge that may not be fully documented.
• Translate engineering requirements into maintainable MATLAB functions, analysis workflows, and visualizations.
• Validate new or modified analysis methods against known datasets and existing engineering results.
• Investigate discrepancies and work with subject-matter experts to identify whether they originate from data processing, algorithms, assumptions, or implementation.
• Improve usability and documentation so future engineers can understand and confidently use the analysis tools.
• Participate in code reviews and incorporate feedback from the mechatronics engineering team.
