▷ (06 / 10 / 2025) Site Reliability Engineer II

Senior Site Reliability Engineer (SRE II)

Own availability, latency, performance, and efficiency for Zafin’s SaaS on Azure. You’ll define and enforce reliability standards, lead high-impact projects, mentor engineers, and eliminate toil at scale. Reports to the Director of SRE.

What you’ll do

• SLIs / SLOs & contracts : Define customer-centric SLIs / SLOs for Tier-0 / Tier-1 services. Publish, review quarterly, and align teams to them.
• Error budgeting (policy & tooling) :
• Run the error-budget policy with multi-window, multi-burn-rate alerts; clear runbooks and paging thresholds.
• Gate changes by budget status (freeze / relax rules) wired into CI / CD.
• Maintain SLO / EB dashboards (Azure Monitor, Grafana / Prometheus, App Insights). Run weekly SLO reviews with engineering / product.
• Drive roadmap tradeoffs when budgets are at risk; land reliability epics.
• Incidents without drama : Lead SEV1 / SEV2, own comms, run blameless postmortems, and make corrective actions stick.
• Engineer reliability in : Multi-AZ / region patterns (active-active / DR), PDBs / Pod Topology Spread, HPA / VPA / KEDA, resilient rollout / rollback.
• AKS at scale : Harden clusters (network, identity, policy), optimize node / pod density, ingress (AGIC / Nginx); mesh optional.
• Observability that works : Metrics / traces / logs with Azure Monitor / App Insights, Log Analytics, Prometheus / Grafana, OpenTelemetry. Alert on symptoms, not noise.
• IaC & policy : Terraform / Bicep modules, GitOps (Flux / Argo), policy-as-code (Azure Policy / OPA Gatekeeper). No snowflakes.
• CI / CD reliability : Azure DevOps / GitHub Actions with canary / blue-green, progressive delivery, auto-rollback, Key Vault-backed secrets.
• Capacity & performance : Load testing, right-sizing, autoscaling; partner with FinOps to reduce spend without hurting SLOs.
• DR you can trust : Define RTO / RPO, test backups / restore, run game days / chaos drills, validate ASR and multi-region failover.
• Secure by default : Entra ID (Azure AD), managed identities, Key Vault rotation, VNets / NSGs / Private Link, shift-left checks in CI.
• Reduce toil : Automate recurring ops, build self-service runbooks / chatops, publish golden paths for product teams.
• Customer escalations : Be the technical owner on calls; communicate tradeoffs and recovery plans with authority.
• Document to scale : Architectures, runbooks, postmortems, SLIs / SLOs—kept current and discoverable.
• (If applicable) Streaming / ETL reliability : Apply SRE practices (SLOs, backpressure, idempotency, replay) to NiFi / Flink / Kafka / Redpanda data flows.
