About the role

We are looking for talented Interns to act as a Full-Stack Software Engineer and join one of our dynamic product teams at DataCamp. In this role, you will contribute to developing and improving web applications that enhance our platform and user experience. Your work will help shape the future of our product, making a meaningful impact on our users.

At DataCamp, we believe AI is transforming how software is built. As an intern, you’ll not only build features, you’ll learn how to leverage modern AI developer tools to move faster, think better, and ship higher-quality software. We expect our engineers to be AI-native: using tools like Cursor, Claude Code, and other AI-assisted workflows to amplify their impact.

As an intern, you will collaborate with experienced engineers to build user-centric solutions, solve technical challenges, and gain hands-on experience in full-stack development. This is a great opportunity to grow your skills in a fast-paced environment while working on real-world projects.

Are you excited to gain experience in full-stack development and contribute to an innovative product? Explore the role below and apply to join our team!

Responsibilities

Contribute to building and improving our platform for learning Data Science and Artificial Intelligence.
Gain hands-on experience working with modern frontend and backend technologies to solve real-world problems.
Support the development of new learning features and improvements to existing ones, with guidance from experienced engineers.
Collaborate with team members to build scalable and user-friendly solutions.
Leverage AI developer tools (e.g., Cursor, Claude Code) to accelerate development and continuously improve your engineering workflow.

What are we looking for?

You have some experience or coursework in web development, preferably with technologies like TypeScript, ReactJS, and NodeJS.
You enjoy building things and have worked on projects, whether in school, personal, or previous internships.
You are eager to take initiative and contribute to real-world features with guidance.
You like solving problems and are curious about tackling technical challenges.
You work well in a collaborative team environment.
You are curious about AI and excited about how tools like LLMs and AI developer assistants can improve how software is built.
You experiment with modern AI tools to learn faster, code better, and be more productive.

What’s in it for you?

Opportunity to work in an internationally focused, fast-paced technology start-up.
An exciting job that will offer you technical challenges every day.
A very competitive salary and meal vouchers.
A flexible work schedule and a cool office space.
Free lunch every day, when working from our Leuven.
Working with a great team (everyone says this, but we’re serious—we’re pretty great).

🎯 Who is this job for?

This role is ideal for a Junior/Intern Full-Stack Engineer with basic experience in TypeScript, React, and Node.js, who wants to gain hands-on experience building real product features under mentorship. It suits someone familiar with web fundamentals, eager to learn full-stack development, collaborate in a team, and explore AI-assisted coding tools (LLMs, Cursor, etc.) in practice. You should be curious, proactive, and comfortable working on user-facing features while developing skills in scalable systems and modern development workflows.

💬 Potential Interview Questions

How would you design a simple full-stack feature for an online learning platform using React, Node.js, and TypeScript?
I would split the feature into a frontend UI, backend API, and data layer with clear responsibilities. On the frontend, I’d build reusable React components, and on the backend I’d create typed endpoints with validation and basic tests.
Why is TypeScript useful in both frontend and backend development?
TypeScript helps catch errors earlier, improves code readability, and makes refactoring safer. Using it across the full stack also keeps data contracts more consistent between client and server.
How would you approach building a new feature as an intern on an existing product team?
I would first understand the requirements, existing architecture, and coding conventions, then break the work into smaller tasks. I’d ask questions early, implement incrementally, and use feedback from reviews to improve the solution.
How do you keep a React application maintainable as it grows?
I organize code by feature, keep components small and reusable, and separate UI from business logic. Consistent patterns for state, API calls, and testing make the codebase easier to extend.
How would you design an API endpoint for assigning a course to a learner?
I would define a clear request and response structure, validate inputs such as learner ID and course ID, and handle errors predictably. The endpoint should be easy to extend later for bulk assignment or additional business rules.
What is your approach to testing in a full-stack web application?
I would use unit tests for business logic, integration tests for APIs, and end-to-end tests for important user flows. This gives confidence that both the backend and frontend work correctly together.
How do you debug a frontend issue that only happens in production?
I would compare local and production environments, inspect network requests, and review logs or monitoring data. Then I’d reproduce the issue as closely as possible and isolate whether it comes from configuration, data, or API behavior.
How would you use AI tools like Cursor or Claude Code in your workflow?
I’d use them to speed up boilerplate generation, explain unfamiliar code, suggest tests, and help with debugging. I would still review everything carefully and treat AI as an assistant, not a replacement for engineering judgment.
How do you write clean and maintainable code as a junior or intern engineer?
I focus on clear naming, small focused functions, and readable structure rather than clever shortcuts. I also rely on linting, code reviews, and testing to keep quality high.
How do you collaborate effectively in a product engineering team?
I communicate clearly, ask for clarification when needed, and share progress regularly. Being open to feedback and working closely with designers, product managers, and other engineers helps deliver better features.
