Backend Engineer
Want to work on projects that directly impact how we serve our customers? 🚀 Do you want to use your expertise to help a company embrace the power of AI? Are you ready to take ownership of complex challenges in a fast-paced environment?
At Lunar, we are democratizing the power of money and changing the way we all bank, pay, and invest. Since starting in Aarhus in 2015, we've grown rapidly and are now a major player in the Nordics, with offices in Copenhagen, Aarhus, and Stockholm 🚀
So, who are we? Are we a tech company or a bank? Well, we're both breaking free from the usual categories. Here, tech isn't just a cool add-on; it's the core of how we do things. With our own banking license, we go head-to-head with traditional banks. What sets us apart is the mix of tech and financial services, giving us the power to shake up a dusty industry that's ready for a change.
As we continue our journey to becoming the best everyday bank in the Nordics, we are looking for a Backend Engineer to help us build a more automated and AI-driven future for our platform. 🤖 As our new Backend Engineer, you will be reporting to Søren Thiel Berg and be part of a team focused on automating Lunar. The team is currently in the process of expanding the toolbox with e.g. AI solutions. The overarching goal is to automate manual and repetitive tasks in a scalable fashion within the broader Technology function, led by Rolf Njor Jensen.
What will you do?
Design and implement software services to replace tasks and processes currently handled by our RPA platform.
Explore the potential of AI as an increased part of our tech stack.
You will be a mentor and coach to other team members 🤝.
Collaborate with other teams across the organization, helping them build and integrate new solutions.
Work in an agile environment with a high degree of autonomy
