• Own and operate CI/CD pipelines and blue/green/canary deployment frameworks across Production, Staging, and Sandbox EKS clusters • Build and enforce policy-as-code guardrails: automated compliance checks against NIST 800-53, TRM, and VA-specific controls before production deployment • Manage Terraform IaC for all VAEC infrastructure provisioning; ensure all changes are code-reviewed and version-controlled • Lead SRE functions: define SLIs, track SLOs against PWS SLA tiers, manage error budgets, and own reliability reviews • Operate the Istio service mesh: traffic management, mTLS enforcement, and sidecar lifecycle across all EKS namespaces • Lead SAST, DAST, container scanning, and Fortify remediation — maintaining ATO with zero unmitigated critical CVEs • Maintain the onboarding pipeline: IaC-driven runbook bringing new engineers to readiness within contractual timeframes • Support Optional Task surge efforts for DevSecOps/SRE as defined in the Performance Work Statement

• You define and enforce SLOs, SLIs, and SLAs across production • You monitor system health, plan capacity, and automate deployments, patching, and infrastructure provisioning • You diagnose and resolve production incidents fast – including 24/7 on-call participation • You lead post-mortems and turn findings into prevention; maintain runbooks and escalation procedures • You manage cloud infrastructure via IaC and own CI/CD pipeline design and maintenance • You drive scalability, fault tolerance, disaster recovery, and security compliance • You partner with Dev teams on production readiness, Shift Left practices, and error budget management

• Participate in migrating on-prem services to the Cloud; • Configure and tune a variety of services in order to increase system stability, performance and security; • Develop, maintain and improve automation for all our systems; • Capacity planning and performance tuning for high traffic events such as Black Friday; • Get involved in designing and implementation of new features; • Troubleshoot issues and provide support for internal teams; • Identify repetitive issues or tasks and focus on automation and implementation of permanent solutions; • Continuous improvement of monitoring and alerting systems.

• Maintain and optimize core server infrastructure, including bare-metal servers, LXC containers, virtual machines, and cloud environments. • Operate and support core infrastructure services such as Nginx, Puppet, GitLab, Artifactory, Nexus, Harbor, Grafana, etc. • Manage and evolve infrastructure following the Infrastructure as Code (IaC) paradigm. • Handle and resolve incidents related to infrastructure operations. • Collaborate closely with cross-functional teams (network engineers, developers, and other technical stakeholders). • Design and implement high-availability, fault-tolerant, and scalable software solutions. • Monitor service performance and availability using modern observability tools, ensuring system reliability and optimal resource utilization.
