As a Site Reliability Engineer, you will help build out and run production environments, automate operations and maintain and support infrastructure. Drive and establish Service level objectives (SLOs) and metrics to meet reliability expectations of multiple applications.

• Develop and maintain applications on Kubernetes container platform using Helm charts, K8s configurations, and Git Ops workflows for repeatable and consistent deployments.
• Monitor and troubleshoot complex issues involving container networking, zero‑downtime availability, scaling behavior, and cluster reliability.
• Architect, deploy, and optimize resilient cloud‑native systems in AWS using services EKS, Lambda, RDS, Aurora, S3, and VPC networking components.
• Build self‑service deployment capabilities for development teams, enabling application deployments through standardized pipelines.
• Integrate security scanning tools (SAST, SCA, secrets detection, container scanning) into the build pipeline to ensure Dev Sec Ops  alignment.
• Implement automated release strategies using blue/green, canary, feature flags, and zero‑downtime deployment patterns.
• Implement all infrastructure and configuration using Terraform, Cloud Formation, CDK, or Ansible, ensuring consistent and repeatable deployments.
• Develop robust Python, or Bash scripts to streamline operational tasks.

• Implement and manage observability stacks using Cloud Watch, Prometheus, Grafana, ELK/Open search, Jaeger/Zipkin, or Data Dog for full stack visibility.
• Develop proactive alerting strategies to minimize false positives and ensure actionable notifications; establish performance dashboards to measure system reliability and drive continuous improvement.
• Conduct root cause analysis (RCA) for production incidents and drive long‑term remediation through automated guardrails.
• Partner with security teams to implement vulnerability management, patch automation, and continuous compliance monitoring.
• Lead blameless post‑incident reviews and drive implementation of resilient engineering patterns such as retries, graceful degradation, chaos testing, and redundancy strategies.

• Work closely with software engineers, architects, product owners, and security stakeholders to design reliable systems that support mission‑critical government applications.
• Coach development teams on cloud‑native principles, observability, performance tuning, and infrastructure best practices.
• Advocate for SRE/Dev Ops culture, driving automation‑first mindset and continuous improvement across the engineering organization.

• Bachelor's degree in computer science, Engineering, or a related field and 8-10 years of relevant experience.
• 5+ years in SRE, Platform Engineering and Dev Ops supporting operations and maintenance for cloud‑native, scalable, and highly available applications.
• Expertise in scripting (Python, Bash, Go preferred).
• Deep understanding of cloud computing platforms (e.g., AWS, Azure, GCP) and containerization technologies (e.g., Kubernetes).
• Experience with monitoring, logging, and observability tools like Data Dog, AWS Cloudwatch, Splunk etc.
• Experience with service mesh technologies (Istio, Linkerd) and Git Ops platforms (ArgoCD/FluxCD).
• Knowledge of infrastructure as code tools (e.g., Terraform, Ansible) and CI/CD pipelines.
• Experience deploying enterprise software within AWS Services such as EKS, RDS, EC2, Elastic Load Balancers, Lambda.
• Strong problem‑solving and analytical skills, with a keen attention to detail.
• Ability to obtain and maintain a Public Trust clearance.

• AWS Professional‑Level and/or Kubernetes Certification.
• Experience with chaos…
