About the role

Hands-on Site Reliability Engineer focused on cloud infrastructure, network security, and infrastructure as code across AWS, GCP, and Azure. Implements, hardens, and operates multi-cloud foundation with emphasis on network security, egress control, and IaC. Works across production Kubernetes (GKE), Cloudflare, Tailscale, and CI/CD tooling to improve reliability and security posture.

Responsibilities

  • Own the design, reliability, and hardening of multi cloud infrastructure across AWS, GCP, and Azure
  • Build and maintain infrastructure as code (Terraform, Ansible, Helm) as the source of truth for how environments are provisioned and configured
  • Own network security architecture: egress proxy configuration, traffic segmentation, and outbound control across cloud environments
  • Manage and evolve our Cloudflare footprint (DNS, WAF, edge security, traffic routing) and API gateway layer (Zuplo)
  • Operate and secure Tailscale as our zero trust network access layer, including access policy design and rollout to new environments
  • Run production Kubernetes (GKE) with an infrastructure security lens: cluster hardening, network policy, and secure deployment patterns
  • Build observability (Grafana) for network and infrastructure health, so misconfigurations and anomalies are caught before they become incidents
  • Harden CI/CD and deployment pipelines (GitHub, GitLab, ArgoCD) from an infrastructure and supply chain security perspective
  • Manage on-call rotation and incident response for infrastructure and network layer issues, driving root cause analysis and durable fixes rather than one-off patches
  • Reduce toil: identify manual infrastructure work and automate it.
  • Act as the technical bridge between security and platform engineering on anything network or cloud infrastructure related

Qualifications

  • 5+ years in an SRE, infrastructure, or platform engineering role, with hands-on experience running production workloads across multiple cloud providers — this is not an entry point into SRE
  • Proven experience with SRE fundamentals: defining SLOs, measuring toil, running blameless postmortems, and using reliability data to inform engineering priorities
  • Strong, demonstrable experience with AWS, GCP, and Azure, including their networking primitives (VPCs, peering, firewall rules, load balancing)
  • Proficiency with IaC and configuration management — Terraform and Ansible are both in daily use here and you'll be owning them, not just contributing to them
  • Solid network security background, including experience designing or operating egress control and proxy architecture for security and compliance purposes
  • Hands-on Kubernetes experience in production (we run GKE), including Helm and GitOps deployment patterns (we use ArgoCD)
  • Experience with Cloudflare or a comparable edge/CDN/WAF platform, and familiarity with API gateway technologies
  • Practical experience with Tailscale or another zero trust network access solution
  • Genuine on-call experience: you've carried a pager, driven postmortems, and understand the difference between suppressing an alert and fixing the underlying problem
  • Strong scripting and automation ability in Go or Python — you'll be writing tooling, runbooks, and automation scripts, not one-off fixes
  • Clear communicator who can work directly with security, compliance, and engineering stakeholders without a translation layer
