Senior DevOps Engineer (Cloud & On-Prem Infrastructure)
by Trapeze in Information Technology (IT)
The Senior DevOps Engineer (Cloud & On-Prem Infrastructure) is responsible for architecting, implementing, and operating highly reliable, scalable, and secure infrastructures across on-premises and cloud environments in Dubai. The role encompasses automation with Ansible, Foreman, Satellite, PXE/Kickstart, and Infrastructure-as-Code using Terraform. The engineer will build HA clusters, load balancers, and resilient storage for low-latency, high-throughput workloads. Responsibilities include establishing hardened RHEL baselines (CIS, SELinux, firewalld), lifecycle management, deep OS troubleshooting, capacity planning, and observability with Prometheus, Grafana, and ELK. The position requires optimizing Java runtime environments and app servers (JBoss/WildFly, Tomcat; WebLogic a plus), performing JVM tuning (G1/ZGC, heap sizing, thread pools), application profiling (JFR, Async-Profiler, APMs), load and performance testing (JMeter, Gatling, k6), and integrating automated penetration testing and vulnerability scanning (OWASP ZAP, Burp Suite, Snyk) into CI/CD pipelines. Containerization with Docker/Podman and deployment on Kubernetes/OpenShift, hybrid CI/CD pipelines (Jenkins/Azure DevOps), artifact management (Nexus/Artifactory), SBOMs, and image signing are included. Cloud architecture knowledge for Azure, AWS, and GCP, including hybrid connectivity (ExpressRoute, Direct Connect, Cloud Interconnect, VPNs), identity, networking, security, logging, and cost governance, is essential. The engineer leads incident response, post-mortems, MTTR reduction, reliability improvements, and implements secrets management, PKI rotation, and least-privilege access while ensuring compliance. Occasional travel within the Middle East and Europe is required.
