Senior DevOps Engineer
Job Description & How to Apply Below
Purpose of the Role
We are seeking a highly skilled Senior Dev Ops 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/Wild Fly, Tomcat; Web Logic a plus).
- Tune JVM (G1/ZGC, heap sizing, thread pools) and profile with JFR, Async‑Profiler, and APMs (Dynatrace/New Relic/App Dynamics).
- 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/Open Shift (operators, quotas, network policies, storage classes).
- Build secure CI/CD (Jenkins/Azure Dev Ops/…) 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.
- 8+ years of hands‑on Dev Ops or Site Reliability Engineering experience.
- Strong Java runtime expertise: JVM/GC tuning, thread/heap diagnostics, and app‑server ops (JBoss/Wild Fly, Tomcat).
- Experience operating on‑prem such as VMWare.
- Dev Ops certification in Azure, AWS, or GCP would be an added advantage.
