You will also contribute to operational excellence through blameless post-mortem analysis and structured incident learning, ensuring continuous improvement of system behavior and resilience.
As a part of the team, you will work closely with Platform Engineering in a shared cybersecurity model, where SRE focuses on detection and monitoring, while Platform Engineering ensures the secure design and operation of the underlying infrastructure.
