Backend Developer Customer Data Platform

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 Customer Data Platform product team!

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 a vital component at the core of CM.com’s product ecosystem. The CDP serves as the backbone for customer data management, enabling clients to store, structure, and utilize their data effectively. It powers key CM.com solutions like marketing software, customer service tools, and AI-driven platforms such as HALO, making it indispensable for many high-profile customers. You’ll play a vital role in evolving this platform. Your work will directly impact how businesses leverage data to create personalized, data-driven experiences. You’ll focus on:

  • Designing and implementing new features.

  • Building and optimizing data pipelines for complex customer data.

  • Ensuring scalability, reliability, and top-tier performance.

• Work closely in a cross-functional Scrum team (five developers, a Product Owner, and a UX Designer), where you’ll have real influence over technical decisions and the platform’s direction.

• Improve processes using AI, automation and smart tooling

• Make decisions fast, test ideas, and learn from what doesn’t work

• Help shape how this role will look a year from now

• Success is measured by impact, not by perfect plans.

That’s why you ideally have

• Experience with C#, Web APIs, and/or microservices. You have a solid understanding of backend architecture and are comfortable working with relational databases like PostgreSQL.

• Familiarity with building and optimizing data pipelines. Experience with graph databases or large-scale data processing is a plus.

• Experience with cloud technologies like Google Cloud (BigQuery, Bigtable, Pub/Sub) and tools like Terraform.

• Basic knowledge of Kubernetes, Linux/Windows environments, and system monitoring.

• Experience with unit and integration testing to ensure code quality and reliability.

• You live within commuting distance of our Breda office and are fluent in English (Dutch is a plus).

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.

Every CM.com colleague, connects to our 4 shared values:

Drive and Lead

We value your expertise and professional judgement. You understand the mission of CM.com and feel ownership over your role and its contribution to the bigger picture. You take initiative, make decisions and recognize opportunities. Making mistakes is part of moving forward.

Growing Faster Together is not just our purpose, it’s how we work. The growth of our colleagues and our customers is our priority.

At CM.com, we work together. We believe that diverse perspectives lead to stronger outcomes. Diversity is therefore essential to us.

Speed and Change

For more than 25 years, we have operated at the forefront of innovation. Change is not something we respond to, it’s something we actively drive.

You are comfortable with that reality and want to contribute to progress rather than maintaining the status quo.
