** ROLE

SUMMARY:

** You will work on a modern, cloud‑native data platform built on
** Microsoft Azure**, and you’ll have substantial input into how the platform evolves over time. The environment supports large‑scale, business‑critical workloads and is developed for both real‑time and batch processing.

The platform makes extensive use of
** Azure Databricks**, Apache Spark, and Delta Lake to support high‑throughput data pipelines.
** Kafka and Azure Event Hubs
** are used to implement reliable, event‑driven architectures, with schema management and stream processing forming core parts of the system.

The platform places a strong emphasis on
** reliability, observability, and secure delivery**. Teams use Datadog and Azure Monitor, follow Open Telemetry standards, and handle environments using Git‑based workflows and Infrastructure as Code. Automated testing and well‑defined release strategies are central to how changes are built and shipped.##
