Site Reliability Engineer- SB25
Location: antiguo cuscatlan, La Libertad, El Salvador
Department: epay SV, IT, SRE
Workplace: hybrid
Employment Type: full
Description
We’re looking for an SRE who will own reliability, scalability, and day‑2 operations of our Kubernetes platforms—specifically SUSE Harvester (HCI), Longhorn, and clusters managed with Rancher. You’ll enable product teams to ship safely using GitOps (FluxCD) and Infrastructure as Code (Crossplane), and you’ll partner closely with networking and platform engineering to keep services fast, resilient, and observable.
· Operate and harden SUSE Harvester environments: lifecycle management, upgrades, node/cluster health, HA, capacity planning, and incident response.
· Manage Kubernetes clusters (multi‑cluster, multi‑tenant) including cluster creation, upgrades, admission control, API server health, and etc.
· Own CNI operations with Antrea: policy design, network performance, and east‑west traffic observability.
· Run KubeVirt for VM workloads on Kubernetes: plan migrations, right‑size resources, and build reliable pipelines for VM lifecycle.
· Use Rancher to standardize cluster fleet management: provisioning (CAPI), templates, RBAC, and centralized policy/upgrade orchestration.
· Implement GitOps with FluxCD: define release pipelines, drift detection, progressive delivery, and automated rollbacks.
· Provision cloud/on‑prem resources with Crossplane: compose abstractions, manage providers, and enforce guardrails for day‑2 operations.
· Build and maintain SLOs/SLIs: availability, latency, error budgets; automate alerts and runbooks tied to service health.
· Reduce toil through automation: scripting, operators, controllers, and self‑service tooling for developers.
· Participate in on‑call rotations, post‑incident reviews, and reliability roadmaps; drive corrective actions and platform improvements.
Requirements
· 3+ years in SRE/Platform/Systems Engineering (or equivalent) supporting production Kubernetes.
· Hands‑on experience with SUSE Harvester and Longhorn (or comparable HCI + distributed block storage).
· Practical knowledge of Antrea CNI, KubeVirt, and Rancher fleet management.
· Proficiency with FluxCD (GitOps patterns, Kustomize/Helm) and Crossplane (Compositions, Providers, RBAC).
· Strong Linux administration (networking, filesystems, performance), observability (logs/metrics/traces), and scripting (Bash/Python).
· Networking fundamentals (TCP/IP, L4/L7), Kubernetes networking/policies, TLS/cert management.
· Experience designing for HA, capacity planning, backup/restore, and disaster recovery.
