Site Reliability Engineer - Kubernetes Platforms

About the role

epay is looking for a Site Reliability Engineer to own reliability, scalability and day-2 operations of its Kubernetes platforms, specifically SUSE Harvester (HCI), Longhorn and clusters managed with Rancher. The engineer enables product teams to ship safely using GitOps (FluxCD) and Infrastructure as Code (Crossplane), and works closely with networking and platform engineering to keep services fast, resilient and observable. The workplace is hybrid.

Key responsibilities

• Operate and harden SUSE Harvester environments: lifecycle management, upgrades, node/cluster health, HA, capacity planning and incident response.
• Manage multi-cluster, multi-tenant Kubernetes clusters, including creation, upgrades, admission control and API server health.
• Own CNI operations with Antrea: policy design, network performance and east-west traffic observability.
• Run KubeVirt for VM workloads on Kubernetes: migrations, resource right-sizing and reliable VM lifecycle pipelines.
• Use Rancher to standardize cluster fleet management: provisioning (CAPI), templates, RBAC and centralized policy/upgrade orchestration.
• Implement GitOps with FluxCD: release pipelines, drift detection, progressive delivery and automated rollbacks.
• Provision cloud and on-premises resources with Crossplane, managing providers and enforcing guardrails for day-2 operations.
• Build and maintain SLOs/SLIs, availability, latency and error budgets, with automated alerts and runbooks.
• Reduce toil through automation: scripting, operators, controllers and self-service tooling for developers.
• Take part in on-call rotations, post-incident reviews and reliability roadmaps, driving corrective actions and platform improvements.

Required profile

• 3+ years in SRE, Platform or Systems Engineering (or equivalent) supporting production Kubernetes.
• Hands-on experience with SUSE Harvester and Longhorn, or comparable HCI and distributed block storage.
• Experience designing for high availability, capacity planning, backup/restore and disaster recovery.

Required skills

• Practical knowledge of Antrea CNI, KubeVirt and Rancher fleet management.
• Proficiency with FluxCD (GitOps, Kustomize/Helm) and Crossplane (Compositions, Providers, RBAC).
• Strong Linux administration, observability (logs, metrics, traces) and scripting (Bash/Python).
• Networking fundamentals (TCP/IP, L4/L7), Kubernetes networking and policies, TLS/certificate management.

What we offer

• 40 hours per week, weekends off, Monday to Friday 8 am to 5 pm, with paid overtime.
• Paid training, work visa sponsorship and US holidays off.
• Hybrid work, only 2 days from the office, flexible in emergencies.
• Cellphone and internet bonus, life insurance fully covered, optional 50/50 health insurance and half scholarships.
• Annual salary appraisal based on performance, possible paid relocation, Christmas bonus above the law, internal savings and credits association.
