Do you want to be part of building the foundation for one of our new squads, Rosetta? Can you see yourself working to help our banking and financial operations team execute and maintain the ever-growing amount of economic data flowing through our bank? Rosetta needs to operate in our banking systems’ deepest cores and foundations and extract information from a spectrum of external systems. 

Are you up for the challenge? Send us your application now. 💪

A look under the hood - our tech

We have built our internal technology platform on an event-based microservice architecture and have about 250 of them running. Continuous and independent deployability is crucial, as we release about 1000 times to production a month. We aim to be multi-cloud, but with most of our services running in Kubernetes on AWS. We love GoLang but honestly believe in using the right tool for the job: Python, JavaScript, or whatever else gets the job done.

At Lunar, we build the rocket ship while we race to the moon and beyond. To do that, we simultaneously expand our offerings and features while we maintain a solid, optimised and scalable platform for our more than 250.000 customers. It requires steady nerves and a super steady focus doing that.

Your elevator-pitch

Rosetta is all about data, and you love that. You don't necessarily get your highs from building next level predictive models, but more from enabling a rock-solid data foundation of financial and customer data. You know and appreciate the importance of having impeccable quality data, and your friends are sick and tired of you using the phrase "Garbage in, Garbage out" all the time. 

You want to work in an environment where you and your squad are the ones that set the limits, and you want to aim for the moon. You are open-minded and a team player at your very core. So you, of course, want to be part of a diverse team that consists of the right people from all over the business handpicked to complete the mission. 

You have experience working with data, and you have a good idea of how to get your hands on it, align it and expose it to both internal and external consumers.

Finally, you dig financial data and understand the basic needs of balancing and possibly report on it.

The role & tasks

At Lunar, we work in squads, each on a specific mission. A squad consists of cross-disciplinary members that make up all the skills needed to complete the mission, that being developers, line-of-business, QA or plain old subject matter experts. You will be part of squad Rosetta and work out of our Tech-hub in Copenhagen, the newest spawn in our tech community. Tech-hub CPH is so fresh that we expect you to be part of forming a unique style and culture and assist it in growing the hub. 

As a Data Engineer in Rosetta, your primary task will be to ensure the collection, validation, refinement and exposure of data for our core banking operations and our financial team. The job includes tasks like :

  • Collect, and validate event data from relevant internal services.
  • Build integrations with external data sources for ingestion and transformation.
  • Ensure quantitative and qualitative validation of data.
  • Transform and expose data to consumers that being as flat files, databases or API's

The Tech

Rosetta's tech stack focuses on the possibility of working with, getting and making data available to data consumers. To ensure this, Rosetta is the primary consumers, builders and maintainers of the financial data platform 'Enterprise'. Enterprise is planned to be built on an Apache Airflow foundation. It uses S3 buckets and possible Redshift as data storage... unless you can bring forward the arguments for a better stack.

All about you

  • You have at least two years of experience working with data engineering, or the likes of it.
  • You either have an education in Computer Science, Engineering or Data Science, or experience from "the School of Life" that is equal.
  • Experience with some part of the tech stack is a must. That being Python programming, RabbitMQ, Data QA, ETL work, Cloud architecture, or other aspects that will ensure that we can complete the mission from a tech point of view.
  • You do not necessarily have any experience working with financial and banking data, but you have the discipline to ensure that the data is under the strictest governance.

What's in it for you?

  • You will have the unique opportunity to be part of building up not only the new bank of the Nordics but also the brand new Tech-hub from our excellent offices in central Copenhagen.
  • You will be part of a bunch of pretty intelligent techies and ambitious financial nerds from whom you will learn from and grow every day. 
  • You will be part of an informal organisation, where it is not the ironing of your shirt or your title that gives you the mandate to have an opinion but your arguments and passion for continually improving.
  • You will become part of a company that wants to make sure that you are well mentally and physically. This means that Yoga and meditation are encouraged throughout work hours, and if that is not your thing, we have padel tournaments, board games, cycling clubs and much more that you can take part in.

We love diversity and everything that makes us different from everybody else because that makes us extraordinary. We come from all kinds of backgrounds, and speak all kinds of languages, so English is our business language. Our most important value is respect and understanding because only with that mindset can we move forward with supersonic speed.

Are you ready to be part of the journey? 

If you want to be part of Lunar, a place where passion and opinions matter, and we strive for nothing less than awesomeness, then get in touch with us, and become part of Squad Rosetta.

If you have any questions regarding the position, please contact Bank Development Manager Anne Carøe Hald at or Head of Technology, Banking Operations, Anders Kring at, and they will try to answer your questions.
