Senior DevOps Engineer

Position Objective

Job Description & Responsibilities

• Own outcomes that improve the availability of enterprise applications and supporting infrastructure by strengthening operational reliability, reducing preventable downtime, and ensuring production environments remain stable.
• Drive secure and automated delivery outcomes by improving the mechanisms through which infrastructure and enterprise applications are built, tested, released, and changed.
• Improve scalability across platforms and environments by evolving infrastructure patterns and operational practices.
• Strengthen the connection between development and operations teams by establishing workflows, handoffs, and technical guardrails.
• Increase the security posture of infrastructure and delivery processes by embedding operational controls, secure configuration practices, and disciplined change management.
• Reduce operational risk by identifying fragile processes, single points of failure, and environment inconsistencies, then driving remediation efforts.
• Improve observability and operational decision-making by ensuring systems produce the telemetry, alerts, and service-level signals needed to detect issues early.
• Enable development teams to deliver more efficiently by providing dependable infrastructure foundations, standardized deployment pathways, and operational support models.
• Drive continuous improvement in infrastructure and application operations by using incidents, recurring issues, and delivery bottlenecks as inputs.
• Contribute senior-level operational leadership by shaping best practices, influencing engineering standards, and helping teams make pragmatic trade-offs.
• Lead the deployment, health monitoring, and lifecycle management of Container Orchestration platforms (OpenShift/Kubernetes).
• Manage a portfolio of mixed OS environments (Linux and Windows), handling server troubleshooting, kernel tuning, and automated provisioning via Infrastructure as Code (Terraform, Ansible).

Additional Responsibilities

• Oversee public/hybrid cloud infrastructure management (OpenShift, Azure, AWS), optimizing cloud resources and ensuring high availability across zones.
• Develop and execute project plans for CI/CD pipeline optimizations, reducing build times via caching, parallel execution, and multi-stage builds.
• Implement GitOps methodologies and execute zero-downtime releases utilizing Blue/Green or Canary deployment strategies.
• Troubleshoot and resolve pipeline failures, dependency conflicts, and restore broken webhook integrations across the development toolchain (Git, Jira, Azure).
• Act as the primary responder for application slowness, isolating root causes across disk I/O limits, CPU throttling, or network latency.
• Establish robust observability using APM tools (Dynatrace, Datadog), building custom Grafana/Kibana dashboards, and tuning alerts to reduce fatigue.
• Troubleshoot complex network connectivity, DNS, DHCP, and VPN issues using packet analysis tools (tcpdump, wireshark) and optimize Load Balancer configurations (HAProxy, Nginx).
• Identify, assess, and mitigate risks associated with IT infrastructure by applying emergency hotfixes for zero-day vulnerabilities (CVEs) and automating OS/application patch cycles.
• Enforce security hardening (CIS Benchmarks, SELinux) and manage secret vaults to ensure compliance with organizational policies and industry standards.
• Oversee quality assurance processes including successful backup verification and database disaster recovery (DR) drills.
• Enforce FinOps best practices to monitor and control cloud and infrastructure budgets.
• Perform database performance tuning, collaborating with developers on SQL query optimization, index tuning, and managing connection pool limits.

Further Responsibilities

• Allocate and optimize computing resources across namespaces, adjusting Kubernetes Horizontal Pod Autoscaler (HPA) thresholds based on real-time consumption.
• Develop and implement change management strategies to ensure smooth transitions during infrastructure upgrades, platform migrations, and toolchain updates.
• Engage with key stakeholders to ensure alignment on project goals, evaluating organizational impact of infrastructure changes.
• Build and lead trainings and communication efforts to ensure all stakeholders (Developers, QA, Security) are prepared for infrastructure changes.
• Drive continuous improvements in project management and operations practices, automating manual administrative toil with Python/Bash/PowerShell scripts.
• Monitor the latest trends, incorporating innovative technologies (e.g., Site Reliability Engineering practices, SLOs/Error Budgets) into project plans.
• Promote a culture of innovation and excellence within the team, adopting new tools and methodologies to modernize legacy environments.

Qualifications & Experience

• Bachelor's degree in information technology, Computer Science, Engineering, or a related field.
• Advanced degree or relevant certifications (e.g., CKA/CKAD, AWS Certified DevOps Engineer, RHCE).
• 10+ years of experience in IT, with a focus on managing large-scale infrastructure projects, DevOps, or SRE operations.
• Deep understanding of IT infrastructure components, including networking, data centers, cloud services, and cybersecurity.
• Expertise in container orchestration (OpenShift/Kubernetes), CI/CD pipelines (Jenkins/GitLab), and Configuration Management (Ansible/Terraform).
• Expertise in regulatory compliance, data privacy, and information security in IT infrastructure projects.
