Deep expertise in Tomcat, ActiveMQ and Rabbit MQ.
Deploy a Clustered Tomcat environment that connects to a PostgresDB in
Azure.

Role Overview:
We are looking for a highly skilled Middleware Application SME to
support the migration of containerized middleware workloads from
on-premises Kubernetes clusters to Azure Kubernetes Service (AKS). The
SME will assess, re-platform, and optimize middleware services such as
ActiveMQ, RabbitMQ, Apache Tomcat, JBoss, NGINX, Apache HTTP Server,
Kafka, Redis, and similar technologies, ensuring seamless integration
into the AKS platform.

Key Responsibilities:
•             Lead the discovery, analysis, and assessment of
existing middleware container workloads for cloud readiness and
prepare an Application Container services migration strategy on AKS.
•             Review and optimize Kubernetes Container
application manifests, Helm charts, Dockerfiles, persistent volume
claims, config maps, secrets, and custom resources.
•             Evaluate and remediate Application middleware
services compatibility issues for AKS, including storage class
transitions and ingress configurations.
•             Define Application PODs/Container migration
patterns/Wave planning, secret and credential management strategies,
and integration with Azure Key Vault and Azure Container Registry.
•             Collaborate with Application Architects,
infrastructure, and cloud architects to implement HA/DR strategies for
middleware services on AKS.
•             Define CI/CD integration strategies using Azure
DevOps for middleware workload deployment, testing, and version
management.
•             Enable observability by integrating
Azure-native monitoring, logging, and alerting services for
containerized middleware.
•             Provide technical leadership during migration
execution, troubleshooting, and UAT support for middleware services.
•             Document architectural decisions, migration
procedures, and operational guidelines for middleware components on
AKS.

Required Skills and Qualifications:
•             5 + years of hands-on experience with
middleware technologies including:
o             Message brokers: ActiveMQ, RabbitMQ
o             Application servers: JBoss (EAP), Apache Tomcat
o             Web servers/proxies: NGINX, HAPROXY,  Apache
HTTP Server
o             Event/data streaming & caching: Kafka, Redis
•             Strong background in Kubernetes (on-prem or
cloud) with deep understanding of StatefulSets, Services, Ingress,
PVCs, Secrets, ConfigMaps.
•             Experience containerizing and managing
middleware in Docker and Helm-based deployments.
•             Proficiency in CI/CD practices with tools such
as Azure DevOps, Jenkins, or GitHub Actions.
•             Knowledge of Azure native services including
AKS, Azure Container Registry, Azure Key Vault, Azure Monitor, and Log
Analytics.
•             Ability to assess and resolve issues related to
application connectivity, scaling, performance, and security on
cloud-native platforms.
•             Strong scripting skills (Bash, Python, or
PowerShell) are a plus.
•             Excellent analytical and communication skills
with a collaborative approach to cross-functional problem solving.

Preferred Qualifications:
•             Azure certifications (e.g., AZ-104, AZ-400,
AZ-305) or Kubernetes certifications (CKA, CKAD).
•             Experience with multi-region AKS cluster design
and failover strategies.
•             Exposure to hybrid cloud integrations and
service mesh technologies (e.g., Istio, Linkerd).
