dubai, United Arab Emirates Trapeze Group Full time

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 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. 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. 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. 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.

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. #J-18808-Ljbffr
