Senior Data Engineer | B2B Cooperation

Do you love automating things and keeping data platforms reliable? We are looking for a skilled DataOps Engineer to join our Data Team and make sure our data platform runs reliably, securely and cost-effectively, helping drive our company toward a more data-driven future.

The role

You will own the operational side of our data platform: infrastructure, deployments, monitoring and costs. Your work will have a direct impact on product development, customer support processes and overall business strategy, because every report, dashboard and AI tool we build depends on the platform you keep running. If you enjoy taking ownership, automating everything you can and working closely with engineers and analysts, this role is an excellent opportunity for you!

What you’ll actually do

• Maintain and automate our cloud data platform (GCP, Databricks), which powers our reporting suite and internal data systems.
• Manage infrastructure as code with Terraform for GCP and Databricks.
• Build and maintain CI/CD pipelines in GitLab, including Databricks deployments with Asset Bundles.
• Maintain Docker images and runtime environments for Dagster and Airbyte, with zero-downtime upgrades.
• Own development and production environments and the release process.
• Set up observability for the platform and pipelines: alerting, metrics, logs and data freshness monitoring.
• Define SLOs for key pipelines, handle incidents, write runbooks and run postmortems.
• Manage access, IAM, service principals and secrets, following the principle of least privilege.
• Monitor and optimize cloud costs (FinOps) across GCP and Databricks.
• Maintain and support the development of Hermes, our AI analytics environment (deployments, BigQuery datasets, monitoring and tracing in Langfuse).
• Support data lineage, cataloguing and governance with DataHub.
• Work with Data Engineers to run their pipelines reliably in production, and with analysts on data availability, SLAs and self-service access.
• Automate repetitive operational work and help retire legacy tools.
