Internship Program Overview:

Our Interns & Co-ops are our entry-level talent pipeline for GF across the globe. Our goal is to provide students with a meaningful work experience that will equip them with the skills to embark on a career in the fast-paced and growing semiconductor industry after graduation. As an intern at GF, you’ll experience one-on-one mentorship, work assignments that prioritize your growth and potential, professional development opportunities, and the chance to network with executives.

Summary of Role:

This position focuses on advanced modeling and platform development, combining device physics, circuit-level analysis, and machine learning. The Co-Op will work on:

• Establishing the relationship between device-level behaviour and circuit-level performance, and

• Developing automation and software tools (including GUI-based local platforms) to support model QA and model workflow execution.

This role is ideal for students interested in physics-informed ML, data-driven modeling, and practical software tools for semiconductor modeling workflows.

Essential Responsibilities include:

• Under the guidance of senior modeling and research engineers, work on device- and circuit-level modeling research, with a focus on closing gaps between simulation and silicon.

• Analyze device and circuit-level measurement data to understand sensitivities and performance impact of device parameters.

• Develop methodologies to use circuit-level measurements to guide device-level parameter tuning and model calibration.

• Apply machine learning and neural network techniques to modeling, parameter optimization, and data analysis tasks.

• Explore inverse modeling and optimization approaches, including reinforcement learning (RL)–based methods, for automated parameter adjustment.

• Design and develop software tools or a local platform with a GUI to integrate internal modeling resources and support model QA workflows.

• Enable users to configure, run, and monitor existing model workflows through automated or GUI-based interfaces.

Other Responsibilities:

• Perform all activities in a safe and responsible manner and support all Environmental, Health, Safety & Security requirements and programs.

Required Qualifications:

• Education – At least a sophomore at time of application and actively pursuing a Master’s, or PhD in Device Physics & Electrical Engineering or related field through an accredited degree program during the time of internship.

• Must have at least an overall 3.0 GPA and be in good academic standing.

• Language Fluency

• English (Written & Verbal)

Preferred Qualifications:

• Experience working with EDA tool vendors and circuit‑level simulation environments.

• Exposure to compact modeling, parameter extraction, or model QA workflows.

• Background in automation, software tool development, or GUI‑based applications.

• Familiarity with machine learning, data analysis, and deep learning techniques, with particular interest or experience in reinforcement learning (RL).

• Prior related internship or co-op experience.

• Strong written and verbal communication skills.

• Strong planning, organizational, and problem-solving skills.

We Offer:

• 20 h/week, aligned with university schedule

• Monthly Scholarship

• 1 - 1.5 years duration

• Top Office Location
