Summary We are seeking a proactive and detail-oriented Site Reliability Engineer II (SRE II) to join our 24/7 Operations team in a hybrid capacity. In this role, you will provide round-the-clock, eyes-on-glass monitoring, proactive incident response, operational maintenance, and continuous compliance support across our hybrid environment—spanning bare-metal on-premises Red Hat Enterprise Linux (RHEL) servers, AWS (Commercial and GovCloud), and Kubernetes (EKS) infrastructure operating under strict FedRAMP standards. As an SRE II, your primary responsibility is maintaining platform availability, hardware reliability, and security posture through real-time telemetry monitoring via Prometheus and Grafana, log troubleshooting and root cause analysis in Kibana and Elasticsearch, rapid incident triage in Slack, execution of automated deployments and GitOps continuous delivery via GitLab CI/CD, ArgoCD, and Argo Workflows, and consistent enforcement of FedRAMP security controls (NIST SP 800-53). You will operate in a structured shift model covering weekdays and weekends to ensure 24/7/365 hybrid platform uptime. 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.

1. 24/7 Eyes-on Monitoring, Log Troubleshooting & Incident Triag e • 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
