Internship Overview

The Grainger Technology Group (GTG) internship is a 10-week, paid program based in our downtown Chicago office where interns work across teams such as Product Engineering, Cybersecurity, Applied Machine Learning User Experience, Digital Experience Analytics, and more to help build the technology that keeps Grainger and its customers moving. As a GTG intern, you will be treated as a member of the team and contribute to meaningful work tied to real customer and business outcomes, not a separate side project. You will gain hands-on exposure to modern technology stacks, digital platforms, AI-enabled workflows, and enterprise systems while learning from experienced team members. Throughout the summer, you will also participate in networking, social, and professional development events and present the work you accomplished to senior leadership.

Position Details

As a Data Science Intern on the Digital Experience Analytics team, you will use statistics, modeling, experimentation, and data storytelling to help Grainger better understand digital customer behavior and improve customer-facing and enterprise digital experiences. You will partner with analytics, product, technology, and business stakeholders to frame questions, evaluate data, develop models or analyses, and translate findings into recommendations that can guide decisions.

This role is ideal for someone who enjoys solving ambiguous problems, exploring large datasets, and connecting technical analysis to business impact. You will gain exposure to modern data platforms, statistical and machine learning techniques, digital analytics tools, and AI-enabled workflows while learning how data science influences product and customer experience decisions at scale.

• Partner closely with current team members on ongoing activities such as ad hoc analysis, A/B testing, troubleshooting, and measurement planning.
• Learn how a modern analytics team operates and how data influences digital products, customer experience, and technology decisions.
• Demonstrate ownership, curiosity, adaptability, and critical thinking while contributing as part of the team.
• Present your work, impact, and key learnings to technology leaders at the end of the internship.
