Senior/Staff Site Reliability Engineer

You are a seasoned SRE who keeps production infrastructure running at scale. You own the reliability and availability of customer-facing systems — from Kubernetes clusters to deployment pipelines to the networking layer that connects it all. You think in SLOs, automate ruthlessly, and treat every incident as a chance to make the system better.

Key Responsibilities

• Own and operate our Kubernetes infrastructure: cluster lifecycle, upgrades, networking, and multi-tenant isolation for customer workloads
• Build and maintain CI/CD pipelines and deployment infrastructure
• Leverage AI to an extreme level to automate analysis and resolution of production issues, and improve software development speed, reliability and maintainability
• Build dashboards, alerting, and anomaly detection across our systems
• Define and enforce SLOs and build out incident response processes
• Manage and improve our networking, load balancing, and service mesh configurations
• Drive reliability improvements across the stack through automation, runbooks, and chaos engineering

Requirements

• 5+ years experience in managing critical production systems and software development workflows
• Strong production experience setting up and operating Kubernetes at scale, using infrastructure-as-code (Terraform, Ansible)
• Deep knowledge of Linux networking, container networking (CNI plugins, VXLAN, BGP), and DNS
• Experience building CI/CD systems and GitOps workflows (FluxCD, ArgoCD)
• Proficiency in Python and either Go or Bash for tooling and automation
• Strong experience with logging, monitoring and alerting (Prometheus, Grafana, Loki, Thanos, VictoriaMetrics, Datadog)
• Excellent communication and ability to drive technical decisions across teams
• Self-starter who executes quickly, takes ownership, and constantly seeks improvement

Nice to have

• Experience with managing GPU and AI/ML workloads
• Experience with kernel-based monitoring and routing (eBPF, XDP)
• Experience with security tooling (Falco, Coroot, SIEM)
• Experience with bare metal Kubernetes networking (Calico, Cilium, MetalLB)
• Experience with distributed storage systems (Ceph, Longhorn, etc.)

Compensation

• $180,000-250,000 plus equity + benefits
