Backend & API developer 🎯

Relewise offers a personalization and search platform (SaaS) used by E-commerce and Marketing managers to provide better CX and thereby increase sales and conversion rates. We are headless and can be integrated into any e-commerce, marketing automation, or app platform via our REST API.

As a backend and API developer you will be implementing new features as well as improving upon existing functionality within our platform.


We also expect that, over time, you will be comfortable with development in our core engine, which collects, analyze, and report on behavioral data collected from our customers in real-time. Everything is built ground up to provide performance and flexibility, which is one of the unique features of Relewise. We do not rely on any database or third-party frameworks. It may sound geeky — and we are not afraid to admit that it is.

You will get to:

  • Be a key contributor to the design, development, and ultimately operation of the personalization platform
  • Work with highly skilled and passionate colleagues
  • Help implement continuous improvements of our internal tools and processes

We expect you to have:

  • Experience working with large datasets and high throughput, high-performance systems
  • Rigor in high code quality, SOLID principles, and another engineering best practices
  • Multiple years of experience working in C#

It's a bonus if you:

  • Have hands-on experience in large-scale system architecture, high scalability, and availability, and optimization
  • Have a high level of statistical and mathematical knowledge and experience
  • Can share some of the code you’ve written, for example from side-projects
  • Have Azure Cloud experience
  • Are fluent in Danish
