Ready to build and shape the backend of Europe’s leading online auction platform?

Are you passionate about developing robust, scalable microservices that power millions of transactions each year? Do you want to work with modern technologies and make a real impact on how buyers and sellers interact across Europe? If so, we want to hear from you.

At TBAuctions, we believe everything has value — and that includes your code. We're committed to innovation, transparency, and delivering exceptional auction experiences. Our team is diverse, hands-on, and driven by results. We make bold decisions, move fast, and support each other along the way.

What you'll do

As a Server-side Developer, you’ll play a key role in developing and migrating critical backend services for our auction platforms.

  • Design, build, and maintain JVM-based microservices that power inventory, listings, bidding, and payment flows.
  • Lead the migration of Klaravik’s legacy backend systems into our scalable microservice architecture.
  • Collaborate with cross-functional teams across the Netherlands, Germany, Poland, and Sweden.
  • Tackle technical challenges hands-on, contribute to architectural decisions, and help define the future of our platform.

What you bring

  • Strong experience with JVM languages (Scala, Java) or Kotlin for backend
  • Affinity with or interest in functional programming
  • Experience with cloud platforms (Azure preferred; AWS or GCP also welcome)
  • Familiarity with microservices and distributed, event-driven systems
  • Professional proficiency in English (no Swedish required)

Bonus points if you know

  • Kotlin with Ktor and Arrow
  • Queue systems like Service Bus, RabbitMQ, or OpenMQ
  • Databases such as Azure SQL, Redis, or MongoDB

Don’t meet every requirement? No problem. If you’re motivated and eager to grow, we’d still love to hear from you.

What we offer 🥳

  • A modern office in central Lund, steps from the train station and public transport
  • Flexible hours to support work-life balance at every stage of life
  • 6 weeks paid vacation, wellness allowance, pension plan, and health insurance
  • Competitive salary and growth opportunities through continuous learning
  • A supportive team that values hard work — and a good sense of humor ✨
