Backend Developer Customer Data Platform

We turn every customer interaction into an opportunity. We connect conversations, customer data and payments with AI Agents so that companies can deliver personal customer journeys at scale: both online and in person.

“The entire customer journey. One platform”

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

You take initiative, make decisions and recognize opportunities. Making mistakes is part of moving forward.

The growth of our colleagues and our customers is our priority. You like to experiment, learn continuously and actively share knowledge and insights with others.

We work together and we believe that diverse perspectives lead to stronger outcomes. You value the social side of work, you show genuine interest and care about one another’s well-being.

By welcoming AI Agents into our organisation, we fundamentally change how work is done. You are comfortable with change and you love working in a high paced environment.

As a Backend Developer 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.

• Design and implement new features for both the Customer Data Platform and its newly launched successor, the Customer Context Platform. Richer, smarter, and built for a world where AI only delivers value with the right context at the right time.

• Build and optimize data pipelines that handle complex customer data at scale.

• Ensure scalability, reliability, and top-tier performance across both platforms.

• 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.

• Use AI tools actively to improve your own work: experiment, automate, and share what works with your team.

• Experienced in C#, Web APIs, and microservices, with a solid grasp of backend architecture and relational databases like PostgreSQL.

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

• Familiar with cloud technologies like Google Cloud (BigQuery, Bigtable, Pub/Sub) and infrastructure tooling like Terraform.

• Knowledgeable in Kubernetes, Linux/Windows environments, and system monitoring.

• Thorough when it comes to testing. You write unit and integration tests as a matter of course, not as an afterthought.

• Fluent in English (Dutch is a plus) and based within commuting distance of our Breda office.

• Genuinely curious about AI. You experiment with tools like ChatGPT or Copilot and you're open to working differently as they improve.

Believe you’d be a great fit for this role, even if you don’t tick every box? Reach out to our Recruitment team! We’d be happy to connect and see if we can make it work together.

We work on-site, move fast, and expect you to bring your own thinking. Priorities shift, AI is actively changing how we work and we embrace that reality. If that sounds like a great environment to you, we'd love to hear from you.

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