• Distributed Systems Knowledge: Solid understanding of distributed systems principles, data consistency, and fault tolerance.
• Communication: Exceptional written and verbal communication skills, with a proven ability to collaborate effectively with diverse technical and non-technical stakeholders.
• Customer-Centric Mindset: A strong commitment to enabling other engineering teams and ensuring their success through reliable and performant infrastructure.

Bonus Points:

• Expertise in Data streaming infrastructure services (Kafka, Redis).
• Experience with other messaging systems or data stores (e.g., Pulsar, Cassandra, ClickHouse).
• Familiarity with CI/CD pipelines (e.g., GitHub Actions, ArgoCD).
