As Senior Developer in the BI&AP Streaming Team, you will play a critical role in designing, developing, and maintaining our real-time data streaming platform.

• At least 5 years of experience in a similar role with a strong track record of leadership and successful project delivery;

• Proven expertise with Apache Kafka and hands-on experience with Flink, Kafka Streams, or similar real-time systems;

• Strong programming skills in Java, Scala, Python;

• In-depth understanding of distributed systems, data consistency models, and streaming semantics;

• Experience with CI/CD, containerization, and infrastructure-as-code tools is a plus;

• Communicate effectively with stakeholders, including presenting technical concepts and project updates.
