Job description

About the Role

We're looking for a Senior SRE with 5+ years of experience to help operate and evolve the infrastructure behind our CDN — from the baremetal edge nodes serving traffic, to the Kubernetes-based control plane, to the observability and data pipelines that tell us what's actually happening on the network. You'll work across the full stack: provisioning and configuration management, CI/CD, Kubernetes, and the logging/monitoring systems that let us catch problems before customers do.

This is a hands-on, senior individual-contributor role for someone who's comfortable moving between low-level networking debugging and higher-level platform/infra automation, and who can drive decisions with less oversight.

What You'll Do

• Operate and maintain our fleet of self-managed baremetal edge servers, using SaltStack (or Ansible) for configuration management and automation
• Manage and improve our managed Kubernetes cluster, deploying and maintaining services via Helm
• Build and maintain CI/CD pipelines (GitHub Actions) for infrastructure and service deployments
• Own and extend observability tooling — Prometheus, Grafana, Alertmanager, and distributed tracing with Grafana Tempo
• Maintain and query ClickHouse at scale — millions of rows ingested daily, with a focus on schema design and low-latency query tuning
• Manage cloud service configuration as code using Terraform
• Diagnose and resolve issues across the stack — from DNS resolution and BGP/routing anomalies to TCP/IP-level performance regressions and applicationWhat

Requirements

What You'll Need

• 5+ years of experience in an SRE, DevOps, or infrastructure/platform engineering role
• Deep understanding of networking fundamentals — DNS, TCP/IP, and CDN concepts (caching, routing, anycast, edge delivery) — you should be comfortable reading a packet capture or debugging a DNS resolution chain
• Solid experience operating Linux systems in production, including self-managed baremetal infrastructure
• Hands-on experience with configuration management tools — SaltStack or Ansible
• Experience with Kubernetes in production, including deploying and managing services via Helm
• Experience building CI/CD pipelines, ideally with GitHub Actions
• Working knowledge of Terraform or similar IaC tools
• Practical experience with Prometheus, Grafana, and Alertmanager for monitoring and alerting; familiarity with distributed tracing (Grafana Tempo or similar)
• Ability to write code in Go or Python for automation, tooling, or internal services
• Strong debugging skills across layers — from kernel/network to application to infrastructure automation
• Good communication skills and comfort working in a small, high-ownership team

Nice to Have

• Experience with BGP / anycast routing in a production CDN or network operator context
• Experience with ClickHouse or another columnar/analytical database at scale
• Experience with Kafka/Redpanda or similar streaming systems for log/data pipelines
• Prior experience at a CDN, ISP, hosting provider, or similar network-heavy operator
• Experience with GitOps workflows (ArgoCD or similar)
