Your impact

Data is the lifeblood of Mollie, fueling decisions for over 250 internal users—from Product Managers to Analysts. As a Data Engineer, you will join the team responsible for the infrastructure that makes this possible. We are currently "changing the engine while flying," transitioning from managed services to a robust, self-hosted stack to gain more control and scalability. We have a strong fundament and we’re continuously adding new functionalities to improve our platform capabilities.

You won't just be maintaining pipelines; you will be engineering the platform itself. You will work on migrating our orchestration layer to Kubernetes, implementing strict data contracts, and building the self-service tooling that empowers the rest of the company to move faster. This is a hands-on engineering role where your work directly impacts the reliability and quality of data at Mollie.

What you'll ship

• Execute the migration of our governance tooling to DataHub on GKE (Kubernetes), giving us greater control and increase our governance capabilities.

• Build and improve self-service tooling and CI/CD pipelines so analysts and engineers can deploy data models independently.

• Enhance data observability and quality by implementing data contracts and monitoring tools to catch issues before they hit stakeholders.

• Develop tools and capabilities for efficient data collection, processing and consumption within the organization.

• Optimize our GCP infrastructure (BigQuery, Pub/Sub, GCS, GKE) for cost and performance.

What you'll bring

• 2–5 years of experience in Data Engineering, Platform Engineering, or Backend Engineering with a data focus.

• Strong coding skills in Python and proficiency in Terraform and SQL.

• Practical knowledge of Infrastructure as Code (Terraform) and containerization tools (Docker, Kubernetes).

• Hands-on experience with cloud platforms (GCP is preferred, but AWS or Azure experience translates well).

• A solid understanding of data orchestration tools like Airflow (or Mage/Prefect/Dagster).

• Experience working in an event driven architecture

• An engineering mindset: you prioritize automation, testing, and reliability over manual fixes.

Grow your way

At Mollie, growth is personal. We believe everyone should have the chance to develop their skills, explore new challenges and shape their career on their own terms.

You’ll get regular feedback and performance reviews to support your development, with fair and transparent salary reviews along the way. Many Mollies move into new roles or take on new projects to stretch themselves, and we actively hire from within to help you take the next step.

No matter if you’re aiming for promotion, exploring a different career path or building new skills, you’ll be supported with the tools, trust and opportunities to grow your way.
