Job description

What you’ll do

You’ll focus mainly on our customer portal and occasionally support the webchat. Together with the team, you’ll help take the platform from version 1 to version 2 — bringing structure, consistency, and speed to our development process.

• Build and maintain robust, high-quality frontend components
• Improve performance, code quality and scalability of our portal
• Think ahead about how we structure and ship features efficiently
• Help streamline our workflows and increase development velocity
• Contribute ideas that make our product stronger and our processes smoother

This role is perfect for someone who likes to get things done, thrives in a growing company, and enjoys having real ownership. You’ll have the space to experiment, suggest improvements, and directly see the impact of your work.

What we’re looking for

We’d love to meet someone who:

• Has 3–5 years of experience as a Frontend Developer (React + TypeScript)
• Is strong technically and comfortable working independently
• Understands how to build maintainable, high-performance applications
• Feels responsible for shipping code that’s clean, reliable and efficient
• Likes collaborating with backend and product teams to solve problems
• Feels at home in a fast-paced, informal and ambitious environment

Why Freeday?

We’re a Rotterdam-based tech scale‑up with big ambitions and a high‑performing team. We prefer working together at the office, because good ideas rarely come from endless meetings but often start at the coffee machine or in front of a whiteboard.

At Freeday, you’ll find people who want to build something meaningful. No big egos. No corporate nonsense. Just a curious group of people using AI to solve real problems and learning every day how to get better at it.

What you’ll get from us

• A role with real influence, where you can make a visible difference
• A team full of smart and driven people
• A solid salary, pension plan, laptop and travel allowance
• An office just 5 minutes from Rotterdam Central
• Space to grow, experiment and make mistakes (because that’s how you learn)
• Regular drinks, fun team activities and plenty of laughs along the way
