Purpose of the Role

We are seeking a highly skilled Senior DevOps Engineer to join our growing technology team in Dubai. In this role, you will drive on-prem and cloud infrastructure excellence, ensure reliability across our platforms, and elevate our CI/CD and automation capabilities. You’ll collaborate with cross‑functional engineering teams and contribute to scalable, secure, and high‑performance deployments.

Key Duties and Responsibilities

• On‑Prem Orchestration & Automation
• Automate at scale with Ansible/Foreman/Satellite, PXE/Kickstart, and Infrastructure‑as‑Code (Terraform where applicable).
• Build HA clusters, load balancers, and resilient storage for low‑latency, high‑throughput workloads.
• Red Hat Platform Engineering
• Establish hardened RHEL baselines (CIS, SELinux, firewalld) and manage lifecycle/patching (EUS, kernel upgrades).
• Deep OS troubleshooting (systemd, cgroups, I/O schedulers, NIC offloads) and capacity planning.
• Implement observability with Prometheus/Grafana/ELK, SLO/SLI‑driven alerting, and actionable runbooks.
• Java Runtime & Application Performance
• Operate and optimize Java app servers (JBoss/WildFly, Tomcat; WebLogic a plus).
• Tune JVM (G1/ZGC, heap sizing, thread pools) and profile with JFR, Async‑Profiler, and APMs (Dynatrace/New Relic/AppDynamics).
• Lead automated load testing initiatives using JMeter, Gatling, or k6 to establish performance baselines.
• Implement automated Penetration Testing and vulnerability scanning (e.g., OWASP ZAP, Burp Suite, or Snyk) integrated directly into the CI/CD pipeline.
• Engineer zero‑downtime deployments (blue/green, canary), connection pool/GC tuning, and performance testing (JMeter/Gatling/k6).
• Containers & Hybrid
• Containerize Java services (Docker/Podman) and run on‑prem Kubernetes/OpenShift (operators, quotas, network policies, storage classes).
• Build secure CI/CD (Jenkins/Azure DevOps/…) with artifact management (Nexus/Artifactory), SBOMs, image signing, and policy gates.
• Cloud knowledge (Azure, AWS, GCP)
• Design and operate workloads across Azure, AWS, and GCP, choosing the right service for the job (IaaS, managed DB, cache, messaging, observability).
• Implement consistent patterns for identity, networking, security, logging, and cost governance across providers.
• Build hybrid connectivity (ExpressRoute/Direct Connect/Cloud Interconnect, site‑to‑site VPNs) between on‑prem and cloud estates.
• Reliability & Security
• Lead incident response and post‑mortems, drive MTTR down and reliability up.
• Implement robust secrets management, PKI/cert rotation, and least‑privilege access; collaborate on audits and compliance.
• Review the duties and responsibilities of this role and group into subheadings

Education and Experience

• 8+ years of hands‑on DevOps or Site Reliability Engineering experience.
• Strong Java runtime expertise: JVM/GC tuning, thread/heap diagnostics, and app‑server ops (JBoss/WildFly, Tomcat).
• Experience operating on‑prem such as VMWare.
• DevOps certification in Azure, AWS, or GCP would be an added advantage.
