Who is Mr. Watts?
We’re a tight-knit group of tech enthusiasts who build beautiful and useful things for organizations like EUROCONTROL, IKEA, Orange, DEME, Burger King, and Port of Antwerp-Bruges. Whether it’s a Digital Twin of European airspace or intuitive interfaces for enterprise platforms, we take pride in work that pushes boundaries. Curious about what we build? The walkthrough video of the project we did for EUROCONTROL serves as a great example of how we blend tech and design.
We’re part of the Cronos Group, but we operate with the flexibility and creativity of a startup. Our team combines senior engineering skill, genuine camaraderie, and a passion for building clean, scalable, and modern software. No fluff—just results and good energy (and good music).
What You’ll Do
You’ll join a team of experienced developers working on custom frontend applications for our clients—each project is different, but always innovative.
Your main focus:
* Build performant, accessible, and delightful React frontends based on modern standards and designs.
* Collaborate closely with the UX designers to deliver real impact to end users.
* Integrate with APIs (REST, GraphQL, or OpenAPI-spec’d) and help shape the data contracts.
* Think about UX, performance, maintainability, and modularity in everything you build.
* Learn and contribute in adjacent areas such as NodeJS, .NET, and Azure—if desired.
If you're into full-stack work, you might also:
* Implement services in NodeJS or .NET / C#.
* Help define backend architecture and APIs.
* Contribute to infrastructure, CI/CD pipelines, and cloud environments (mostly Azure).
What You Bring
Core Skills
* 2 to 4 years of experience building frontend web applications.
* Strong grasp of HTML, CSS, and modern JavaScript / TypeScript.
* Real-world experience with React, and common tools like Redux, React Query, or similar.
* Comfort working with NodeJS / NPM for frontend development.
* Able to consume APIs and collaborate with backend engineers.
* Fluent communication in Dutch and English, both spoken and written.
Bonus points for:
* Experience with backend technologies (.NET, NodeJS, PostgreSQL).
* Understanding of CI/CD, automated testing, and version control (GIT).
* Familiarity with Azure services, containerization, and/or security best practices.
* Interest in evolving into a full-stack or even solution architect role over time.
Why You’ll Love Working Here
* You’ll work with a warm, senior, and multi-skilled team that supports each other and builds great things together.
* The scope of the role can grow as your ambition grows—want to be full-stack? Want to lead projects? We're here for that.
* We work hard but never forget the fun. Expect spontaneous ideas, smart conversations, and the occasional bad joke.
* Flexible hours and a dynamic office at Corda Campus in Hasselt.
What’s in it for you?
* Competitive salary based on your experience.
* A beautiful company car with fuel / charging card.
* 20 vacation days + 12 ADV days.
* High-performance laptop and your choice of iPhone, iPad, Pixel or other device.
* Smartphone subscription & internet at home.
* Hospitalization & group insurance.
* Meal and eco vouchers.
* Projects you’ll be proud of.
