  We help the world run better
  <br/>
  <br/>
 </strong>
 At SAP, we keep it simple: you bring your best to us, and we'll bring out the best in you. We're builders touching over 20 industries and 80% of global commerce, and we need your unique talents to help shape what's next. The work is challenging &ndash; but it matters. You'll find a place where you can be yourself, prioritize your wellbeing, and truly belong. What's in it for you? Constant learning, skill growth, great benefits, and a team that wants you to grow and succeed.

 <strong>
  What You'll Build
  <br/>
  <br/>
 </strong>
 Ready to shape the infrastructure that powers SAP's cloud commerce? As a Developer on the BTP Metering &amp; Reporting team, part of SAP's Commercial Foundation Services, you'll build the cloud-native services that track and report how SAP products are used by customers worldwide &ndash; feeding directly into billing, compliance, and consumption-based business models. Your work will be embedded at the core of the SAP Business Technology Platform and will be relied upon by dozens of product teams across SAP and its partners.
 <br/>
 <br/>
 You'll design and implement backend services and REST APIs in Java and Go, work with cloud infrastructure on Cloud Foundry and Kubernetes, and integrate with SAP billing and compliance systems. You'll own features from the first line of code through to production, working within an Agile team that values quality, accountability, and continuous improvement.
 <br/>
 <br/>
 <strong>
  What You Bring
  <br/>
  <br/>

 <ul>
  <li>
   3+ years of backend development experience in Java, with solid knowledge of Spring (MVC / Boot) and REST API design.
  </li>
  <li>
   Hands-on experience with SQL databases &ndash; you're comfortable with data modelling, schema design, and writing efficient queries.
  </li>
  <li>
   A cloud and automation mindset: you've worked with CI/CD pipelines (Jenkins, Maven) and container technologies (Docker, Kubernetes or Cloud Foundry).
  </li>
  <li>
   Strong engineering fundamentals &ndash; clean code, SOLID principles, and a genuine commitment to test coverage.
  </li>
  <li>
   A collaborative, results-driven approach: you communicate clearly, take ownership of your work, and help teammates when they're stuck.
  </li>
  <li>
   Experience with Go, or eagerness to pick it up quickly &ndash; it's part of our stack.
   <br/>
   <br/>
  </li>
 </ul>
 <strong>
  Where you belong
  <br/>
  <br/>
 </strong>
 You'll join a small, international team of engineers in Berlin who care deeply about code quality and take pride in running reliable, scalable systems. We work in short Agile cycles, review each other's code openly, and make technology decisions together. If you like understanding how your software performs in production &ndash; not just in theory &ndash; you'll feel right at home. SAP invests in your growth through learning platforms, mentoring, and the opportunity to move across a large, diverse organization.
