About the team

Our Backend Team works primarily with Scala, Apache Kafka, ElasticSearch, Clickhouse, Kubernetes, and cloud environments (Azure and GCP).

• Capacity to plan and scale systems to keep up with incredible growth.  

• Excellent troubleshooting and debugging skills.  

• A passion for building tools and automating everything.  

• Strong analytical skills.  

What will convince us even more?

• Solid understanding of JVM internals (GC, profiling, heap and thread dumps).
