About Us
Collectmaxx is a Dutch company on a mission: help businesses get paid faster, at lower cost. We're a small, driven team building a fully automated, white-label dunning platform that combines 25+ years of collections expertise with modern AI technology.
We deliver increased recovery rates, maximized returns, and better financial health for our clients across Western Europe — with a strong focus on the Benelux, Austria, and Switzerland — all while maintaining the highest standards of integrity and trust.
In 2026, we're upgrading our proven enterprise platform into a PaaS setup, enabling us to serve enterprise clients with custom implementations and SMBs through a self-serve model — all on the same infrastructure. It's an exciting time to join.
The Role
We're looking for a backend-leaning Full Stack Developer to help build and evolve our communication platform. We enable our clients to reach their customers through Voice, SMS, and email — and we're continuously expanding to new channels and adding more flexibility in follow-up actions.
You'll work with a modern stack centered around PHP (Symfony), JavaScript, and MySQL, using GitHub/Bitbucket for version control. Experience with AWS (S3/SQS/EC2) and GraphQL is a strong plus, and familiarity with MongoDB is a bonus.
There's no shortage of challenges here — and plenty of room to make a real impact.
What You'll Do
As a Full Stack Developer at Collectmaxx, you:
Work on integrating new solutions — built or bought — into the Collectmaxx platform
Operate in a cross-functional scrum team where you're responsible for writing clean code with strong business awareness
Onboard and integrate customers onto the Collectmaxx platform and its services
Design generic, reusable solutions that can accommodate multiple customers
Continuously think about how our solutions can be improved and expanded
Are customer-centric, but also critical when evaluating customer needs
Proactively pick up new opportunities to improve what we offer
📍 You'll be based at our office in Rotterdam (max. 60 minutes travel time from home).

📍 You live in the Netherlands and have a valid work permit. We work hybrid, but value face-to-face collaboration — so we ask you to be in the office at least 60% of the time.

The Office
We've got a desk waiting for you in the heart of Rotterdam. Our office is in The Red Apple, one of the city's tallest landmarks — an open, loft-style workspace with an inspiring view and a proper coffee machine. Metro station Blaak and the Markthal are just a short walk away.
