Data Platform Engineer at Online… · Delft

3 reasons you should join our team as Data Platform Engineer:

1. High-throughput payments scale: With over 10 million users, millions of transactions, and billions in volume flowing through our platform, you’ll tackle complex, real-world data challenges where consistency and millisecond precision actually matter.

2. Production scale meets greenfield freedom: While our core Snowflake data warehouse is live in production, major platform pillars (from modern orchestration and reporting architecture to automated team onboarding) are still genuine greenfield domains waiting for your blueprints.

3. The best of both worlds: The flat hierarchy and autonomy of an ambitious fintech scale-up in the heart of Delft, backed by the stability and reach of Worldline.
   

The Role: Scale & harden our data backbone
As our Data Platform Engineer, you will join our core data platform team working alongside your colleague Data Engineer, the DevOps team (4 engineers), and our Data Analyst.

We maintain a clear distinction between platform engineering and business analytics. While our Data Analysts drive business intelligence and reporting insights, your dedicated focus will be purely on the infrastructure, streaming pipelines, cost-efficiency, and data integrity that power our core platform.

What you will be working on:

• Real-time DWH & Pipeline evolution: Transition our current architecture toward a robust, real-time data warehouse. Build and optimize streaming and batch ingestion pipelines with minimal production disruption.

• Orchestration architecture: Implement and own orchestration tooling (such as Dagster or Airflow) to automate pipelines and enable self-service onboarding for other teams.

• Data quality & validation controls: Establish automated validation checks, schema enforcement, and reconciliation mechanisms across pipeline stages to guarantee high-integrity payment data.

• Monitoring, notifications & alerting: Build end-to-end observability across the data lifecycle, ensuring timely alerts and actionable metrics before anomalies hit downstream systems.

• Cost control & resource optimization: Actively monitor, analyze, and optimize AWS and Snowflake usage to keep pipeline execution and storage lean and scalable.

• Integration architecture: Implement scalable ingestion patterns, utilizing tools like AWS DMS, Glue, and Snowflake native connectors to streamline our data ingestion.

• Infrastructure as Code & Security: Automate cloud resources using Terraform and CI/CD pipelines, enforcing strict IAM and RBAC policies aligned with industry standards and security best practices
