Backend Developer Museums & Parks

You probably remember the best customer journey you’ve ever experienced, and the worst one too. But why is that? What can businesses do to keep you engaged, solve your problems, and make your life easier and more beautiful, not just in one moment, but across every interaction?

“The entire customer journey. One platform”

People move between channels, platforms, apps and physical locations without thinking about it. Wherever your journey starts and wherever it continues, our goal is simple and ambitious: “Enable growing businesses to serve, sell, interact and engage through one Global AI Powered Customer Engagement Platform. We connect conversations, customer data and payments with AI Agents, so that businesses all over the world can grow faster, together.

All our services are fully integrated within our unique business structure, consisting of four business units: Connect, Pay, Live, and Engage.

Now, we’re looking for a Backend Developer to join the Museums & Parks team (Live).

What you will do

We are building the ultimate Global AI-Powered Customer Engagement Platform that lets businesses connect with customers, automate work, and handle every interaction through one reliable, user-friendly platform. That is our mission for 2026.

In your first 12 months, you will:

• Take ownership of backend PHP development for our Global Ticket platform
You’ll play a key role in building scalable, secure, and high-performing solutions that power seamless ticketing experiences for iconic clients like the Van Gogh Museum, Heineken Experience, Toverland, and international landmarks like the Notre Dame in Paris.

• Work closely with senior developers and external partners
You’ll collaborate with a team of four senior developers and integrate external services (APIs) to enhance the functionality of our platform, ensuring it meets the dynamic demands of the Museums & Parks industry.

• Improve processes using automation and smart tooling
You’ll tackle challenges that come with international growth, such as multi-currency support, scalability, and security, while continuously optimizing backend processes to deliver value.

• Make decisions fast, test ideas, and learn from what doesn’t work
Our team follows SCRUM principles but prioritizes flexibility and impact. You’ll triage bugs, brainstorm innovative solutions, and adapt priorities to meet the evolving needs of the ticketing industry.

• Help shape how this role will look a year from now
As AI continues to evolve, we expect you to actively explore how it can transform and enhance your own role as a software developer. By leveraging AI tools and methodologies, you’ll have the opportunity to rethink workflows, automate repetitive tasks, and focus on delivering innovative solutions.

• Success is measured by impact, not by perfect plans
Your work will empower museums, zoos, and theme parks to connect with their visitors on their favorite channels and devices, creating a journey that starts long before the visit and continues long after.

That’s why you ideally have

• A bachelor’s or master's degree related to IT, Software Engineering, or Computer Science

• Minimum of 2 years of backend development experience. Experience in PHP and Symfony framework knowledge is a plus

• Fluency in English. Dutch is a plus

• Residence within commuting distance from our office in Amsterdam

The reality at CM.com

We believe honesty creates better matches. So here it is:

• You work on-site with your team, collaboration happens face to face.

• Priorities can shift quickly as technology and insights evolve.

• AI will change how your role looks, fast. Some tasks you do today may disappear next year.

• We move before everything is finished or polished.

• For this position, we can only consider candidates who already hold a permanent work and residence permit for the Netherlands.

If that excites you, you’ll probably feel at home here. If you’re looking for predictability and fixed boundaries, this may not be the right place.
