Join Lunar and help us redefine banking!

Are you a Backend Engineer who is passionate about building products that users love? At Lunar, we build world-class tech to make banking easy and intuitive for our users. We’re looking for a sharp and experienced Backend Engineer to join our team in Aarhus to help build the features that power our app and web platform.

We're both a tech company and a bank, and that combination is at the core of who we are. With our own banking license, we challenge traditional banks by putting technology at the center. We're building a product that will shake up a dusty industry, and we do it with a strong focus on user experience and top-tier tech competencies.

What will you do?

In our Lunar we work with a strong 'You build it, you run it' mindset. This means you’ll have full ownership of the products you build. You won't just develop new features, but you'll also be responsible for ensuring they run smoothly in production and provide value to users. Your responsibilities will include:

• Designing, developing, and operating seamless backend solutions developed in GO for our user-facing products, with a high degree of influence on the product itself

• Designing and implementing products on a modern tech stack powered by an event-driven & event-sourced architecture that ensures robustness and scalability.

• Work with a best in class micro-service setup where we deploy hundreds of times to production a week - supported by internal tooling & dedicated devops teams to make the developer experience top notch!

• Designing and maintaining robust APIs (HTTP/Swagger, GraphQL) in collaboration with frontend engineers for app and web

• Taking responsibility for automated tests and closely monitoring products with modern observability tools (Grafana, Falcon LogScale, Prometheus) to ensure high quality and continuous optimization.

• Utilizing AI (Cursor, Gemini, Claude, etc.) to improve quality and speed while coding and implementing AI into the product where it makes sense.

• Collaborating closely with product managers, designers, and data scientists to deliver products that users love.
