About the job
We are looking for someone that can help with our auction brand Klaravik's migration on the backend and can help adapt the current Klaravik process into the new TBAuctions Kotlin microservice codebase. Ideally you are in the greater Copenhagen region to work with our development teams in our office in Lund.
You will work with a tight-knit development organization locally in Sweden and also internationally in the Netherlands and Poland. We will spend a lot of time on skills development and training to make the transition between platforms as smooth as possible while learning by building new features in the system together
We have created a white-label storefront website to support our major auctioning brands: klaravik.se, troostwijkauctions.com, and vavato.com and we plan to continue the migration for all our other brands to continue with our vision, better together.
In addition to our white-label storefront we have built a modern backend infrastructure to support the continuous growth of our business and the growing volume of items sold and bids made on those items. TBAuctions handles 2.9 million items annually, has 30 million website visits per month, can reach 10 bids per second, and employs over 800 people.
Your main tasks
As a Kotlin Server-side Developer, you will build, optimize, and maintain critical backend services that resonate with our diverse audience of bidders and sellers. You’ll be responsible for migrating Klaravik’s backend processes into our modern Kotlin microservice codebase, collaborating closely with cross-functional teams in Amsterdam, Sweden, and Poland to drive growth. Through a blend of strategic problem-solving and hands-on coding, you’ll help position TBAuctions and its brands as leaders in the online auction industry.
- Design, develop, and maintain Kotlin-based microservices that handle inventory management, auction listings, bids, and payments.
- Lead and support migration efforts for Klaravik’s backend into our new infrastructure.
- Collaborate with local and international teams to ensure high-quality, scalable solutions that meet business and user needs.
