Job description

Lunar is a Nordic challenger bank building the future of financial life with AI at the core. Our engineers, designers, and product people work on problems that actually matter.

Fully licensed and founded in 2015, with offices in Copenhagen, Aarhus and Stockholm.

As our new Senior Data Platform Engineer you'll join the Squad Matrix team based in Copenhagen, reporting to Jesper, working to build Lunar's self-service analytical data platform, Hubble.

What will you do?

• Build product-grade Flink streaming ingestion pipelines, working with cutting-edge streamhouse technologies (Paimon, Iceberg, Fluss, StarRocks) to move data in real time.
• Own end-to-end projects that add new capabilities or fix issues across our data stack, from ingestion through to the warehouse.
• Ensure consistent, reliable daily operations of our data warehouse - the foundation other teams build on every day.
• Provision cloud infrastructure with Terraform and run services in Kubernetes, keeping the platform deployable and dependable.
• Support stakeholders across the business with data requests, and use agentic workflows to scale your impact.

What are we looking for in you?

• Senior-level experience in data engineering, with a track record of owning platform-level systems, not just pipelines.
• Experience with stream data processing using Flink, Spark, or similar.
• Experience with cloud infrastructure (AWS, GCP, or similar), and comfort making architectural trade-offs.
• Programming experience in one or more of Golang, Scala, or Python, plus solid SQL.
• Ability to work closely with non-engineering stakeholders, translating platform capabilities into something analysts can actually use.

Benefits and perks

• 4 days in the office. We're a team that builds together, thinks together, and moves together. Showing up is part of how we work.
• State of the art equipment. The newest computer, monitor, mouse, and keyboard. We want you to do your best work without anything slowing you down.
• Pension, health insurance, and enhanced parental leave. From your financial future to your family moments. We've got you covered.

We welcome applications from candidates of all backgrounds. If you need any adjustments during the recruitment process, please let us know.

Depending on the regulations in the country where you will be employed, we will ask to see or obtain information about your criminal record.
