24/7 Shift & On-Call Expectations
This position requires active participation in a 24/7/365 operational shift model:
Round-the-Clock Coverage: Active "eyes-on-glass" monitoring during scheduled shifts (day, evening, night, and weekend rotations).
Weekend & Holiday Rotation: Scheduled weekend shifts and holiday coverage to ensure continuous operational readiness across both on-premises data centers and cloud regions.
On-Call Escalations: Primary and secondary on-call responsibilities during and outside regular shift windows to meet stringent FedRAMP Incident Response (IR) SLAs.
Real-time Collaboration: Continuous presence in operational Slack channels and ChatOps bridge rooms for instant incident mobilization.
Key Responsibilities
1. 24/7 Eyes-on Monitoring, Log Troubleshooting & Incident Triage
Maintain continuous monitoring of production telemetry across bare-metal RHEL servers, EKS clusters, and AWS cloud environments.
Act as first responder to high-priority alerts generated by Prometheus and Alertmanager, performing immediate triage and root cause investigation.
Perform deep-dive log troubleshooting using Elasticsearch and Kibana (building queries, analyzing container/application stdout logs, systemd/journald logs, and ingress traffic logs) to isolate error patterns and service failures.
Coordinate incident resolution bridges in Slack, engaging secondary on-call engineers, security teams, or infrastructure engineers as required.
Maintain rigorous adherence to Incident Response SLAs and document timeline logs for post-incident reviews (RCAs).
2. Bare-Metal On-Premises RHEL Server Support & Hardware Operations
Provide operational support for bare-metal on-premises Linux servers (RHEL), including OS configuration, system maintenance, and day-to-day lifecycle administration.
Diagnose physical network interface bonding, link aggregation, VLAN tagging, and local server connectivity issues on bare-metal systems.
Coordinate vendor hardware dispatch requests for failing server components and oversee physical parts replacements.
3. FedRAMP Security & Vulnerability Remediation
Execute day-to-day security operational duties aligned with FedRAMP High/Moderate (NIST SP 800-53) standards.
Perform routine vulnerability patching (CVE remediation) across bare-metal RHEL servers, cloud AMIs, Kubernetes worker nodes, and container images within strict regulatory timelines.
Apply operational system hardening based on DISA STIG guidelines and maintain FIPS 140 compliance configurations across both cloud and on-premise operating systems.
Ensure strict Role-Based Access Control (RBAC), SSH key management, and security boundary enforcement across operational environments.
4. Kubernetes (EKS), AWS Infrastructure & Networking Operations
Support day-to-day operations and node maintenance for Amazon EKS clusters across AWS Commercial and AWS GovCloud environments.
Perform Layer 4 (L4) and Layer 7 (L7) secure load balancing troubleshooting, including AWS Application Load Balancers (ALB), Network Load Balancers (NLB), ingress controllers, SSL/TLS certificate termination, and traffic routing issues.
Perform Linux administration tasks including kernel parameter tuning (sysctl), storage expansion, log rotation, and system troubleshooting.
Execute infrastructure changes and updates using Infrastructure as Code (Terraform) in alignment with change control procedures.
Monitor key AWS cloud infrastructure components including VPCs, Security Groups, EC2, IAM, S3, and KMS.
5. CI/CD & GitOps Deployment Operations (GitLab, ArgoCD, Argo Workflows)
Execute, monitor, and troubleshoot automated deployment pipelines using GitLab CI/CD.
Manage application state, synchronization, and rollouts across Kubernetes clusters using ArgoCD (GitOps paradigm).
Monitor, execute, and troubleshoot operational batch processes, system maintenance tasks, and automated pipelines using Argo Workflows.
Facilitate application releases and configuration rollouts using Helm charts, Kustomize, and GitOps workflows.
Validate build pipeline compliance, container security scanning results, and image signature verifications prior to production deployment.
6. Documentation & Operational Runbooks
Maintain accurate, step-by-step incident runbooks, standard operating procedures (SOPs), and triage workflows for both cloud and bare-metal environments.
Write detailed post-incident reports and post-mortems for production impact events.
Identify manual operational overhead (toil) and implement shell scripts (Bash/Python) to streamline routine monitoring, hardware checks, and maintenance tasks.
