AI Automation & Agent Builder Internship

Monday Merch is building a faster, smarter way for companies to create branded merchandise. Behind every order is a busy flow of product data, supplier updates, customer communication, logistics, and internal tools. This internship is about using AI to make that flow clearer, faster, and easier to trust.

AI is already part of how we build and operate at Monday Merch. We use the newest models and tools, including ChatGPT, Claude, and other frontier AI products, to improve engineering and day-to-day workflows. This internship is about helping push that work further.

As an AI Automation & Agent Builder Intern, you will learn by building. You will sit close to the teams doing the work, spot repeated tasks, prototype useful AI workflows, test them in real situations, and improve them based on feedback.

Location & work mode

This internship is based in our Rotterdam office. We work together in person because the best automation ideas usually come from being close to the teams who run the business every day.

What you’ll work on

• Build internal AI assistants for repeated team questions, customer updates, or operational checks.

• Turn scattered information from emails, spreadsheets, supplier files, order notes, and internal docs into useful structure.

• Create simple automations that remove copying, checking, or status-update work.

• Test prompts, guardrails, and examples so workflows behave reliably.

• Write clear documentation and help teams adopt what you build.

• Measure whether a prototype actually saves time, reduces mistakes, or improves the experience for a team.
