Site Reliability Engineer, Linux (Remote)

Cisco is a technology company developing solutions that connect and protect organizations across physical and digital environments. The Site Reliability Engineer will own Linux operating system configuration, automation, and reliability for a large hybrid infrastructure while supporting its transition to Kubernetes. The role involves infrastructure modernization, production debugging, compliance integration, and improving tooling and operational standards.

Responsibilities:

• Automate Linux host lifecycle management, including configuration, patching, and image creation, to ensure consistent and reliable deployments across our hybrid environment
• Migrate Ansible components from our existing monorepo into isolated, purpose-built repositories to improve maintainability and accelerate infrastructure delivery
• Debug complex production issues across OS, performance, and service layers to minimize downtime and enhance the overall stability of our network services
• Design, build, and improve infrastructure tooling that increases engineering velocity and streamlines adoption of best practices
• Partner with security and compliance teams to embed FedRAMP requirements into our infrastructure-as-code, ensuring that secure practices are built into every deployment
• Lead the transition of workloads to Kubernetes clusters by optimizing container base images and host configurations to support our evolving service architecture
• Own the reliability of critical infrastructure end to end, iterating and adapting as necessary to evolving requirements

Requirements:

• The successful applicant may be performing work in FedRAMP High or IL-5 environments, and therefore, must be a U.S. Person (i.e. U.S. citizen, U.S. national, lawful permanent resident, asylee, or refugee)

• Bachelor's degree in STEM and 5+ years of relevant experience, or Master's degree in STEM and 3+ years of relevant experience or equivalent related work experience
• 5+ years of experience working with Linux in a production environment
• Experience with Python or Ruby for infrastructure automation and scripting
• Experience with Ansible for configuration management at scale
• Experience debugging complex system issues across OS, performance, and service layers
• Ability to work in a hybrid cloud and on-prem environment
• Experience with Kubernetes cluster management and containerization (Docker)
• Knowledge of systems-level languages such as Go or C
• Familiarity with compliance frameworks like FedRAMP or NIST
• Proven ability to lead technical projects from ambiguous requirements to production
• Strong sense of ownership and a proactive approach to identifying and solving systemic reliability issues
