What Makes You Unique:

  • 5+ years of experience on a similar position.
  • Strong experience with the Hadoop stack (Cloudera: HDFS, Hive, Impala, Ranger, Spark, YARN, etc.).
  • Hands-on knowledge of Kubernetes and related container technologies.
  • Experience managing the Data Streaming stack (Kafka, Kafka Connect, connectors, Flink Schema Registry).
  • Track record handling upgrades (zero downtime), migrations, lifecycle and license management.
  • Experience maintaining and optimizing custom Spark solutions.
  • Proficient with CVE (security vulnerability) handling.
  • Skilled in Linux administration and troubleshooting, including Bash scripting.
  • Programming experience in Java, Python, or Go is a plus.
  • Familiarity with monitoring and observability tools (Open Telemetry, Prometheus, Grafana, Splunk) (Cloudera: HDFS, Hive, Impala, Ranger, Spark, YARN, etc.).
  • Experience with the Confluent ecosystem (Confluent for Kubernetes or Strimzi preferred).
  • Excellent cross-functional and stakeholder collaboration, with strong written and verbal English skills.
  • Ability to coordinate activities, priorities, and effective communication between all parties.

Nice to Have:

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
