Job Summary

While stateless applications are easily replaced StatefulSets are the bedrock of our data integrity and service uptime. We are seeking a specialist to architect and manage the entire lifecycle of stateful workloads within our Azure-based MSF (Microservices Framework).

Your mission is to ensure that databases message brokers and persistent storage layers are architected for 99.99% availability. You will move us away from snowflake configurations toward a fully automated self-healing stateful infrastructure where manual intervention is a relic of the past.

Storage Performance & Tuning: Optimize Azure Disk (Premium/Ultra) and Azure NetApp Files integration via CSI drivers to minimize IOPS bottlenecks and latency.
Disaster Recovery Automation: Develop and test automated Snapshot-to-Restore pipelines. Ensure that the Actual State of data volumes can be recovered to the Goal State in minutes not hours.
Infrastructure as Code: Utilize Terraform to provision the hardened Azure foundation (Disk Encryption Sets Proximity Placement Groups and Networking) required for high-performance stateful clusters.

Basic Qualifications:

Kubernetes Internal Mastery: Expert-level understanding of StatefulSet controllers Persistent Volume Claims (PVCs) and the Container Storage Interface (CSI).
Azure AKS Specialist: Deep experience with Azure Kubernetes Service specifically around persistent storage integration and Azure-specific networking constraints.
Automation & Scripting: Proficient in Go or Python/Bash for writing custom controllers or maintenance hooks (PreStop/PostStart) that ensure data consistency during updates.
Reliability Engineering: Proven track record of managing production databases or distributed systems (e.g. Postgres ClickHouse Elasticsearch) on Kubernetes.
