MEET THE TEAM
The Linux SRE team at Cisco serves as the foundational backbone of our infrastructure, responsible for the OS configuration, automation, and base images that power our global hybrid environment. We manage the critical layer across 6,000 servers as they transition into a modern Kubernetes ecosystem, ensuring stability from the kernel up. Our team is a tight-knit group of systems experts who thrive on solving complex, low-level debugging challenges while maintaining high-velocity automation. We are currently tackling the exciting evolution of our infrastructure, migrating from legacy monoliths to isolated, scalable repositories that define the future of operations. It is a dynamic environment where deep technical ownership is valued and every engineer has the autonomy to shape our operational standards.
YOUR IMPACT
The Site Reliability Engineer (Linux) role is the critical link between our low-level infrastructure and high-level service delivery, ensuring the stability of 6,000+ servers as we transition to Kubernetes. You will take full ownership of our OS configuration and automation strategy, serving as a key driver in reducing operational toil for the entire engineering organization. By working across the full stack—from kernel modules to container orchestration—you will directly influence the reliability and security of the Meraki platform. This role offers the unique opportunity to lead infrastructure modernization projects that move us from legacy management to a scalable, automated future.
