That’s why we offer:** * Benefits that truly make a difference * Development opportunities * An inspiring work environment We are seeking a **Senior SRE** with a hands-on profile to assume frontline responsibility for the reliability and stability of our most critical systems. In this role, you will be the **guardian and technical investigator** of our ecosystem. You will resolve highly complex incidents in multi\-cloud environments, playing a **vital role in advanced troubleshooting across our infrastructure**. Your responsibility is to master low-level operations—ensuring efficiency, security, and availability aligned with SRE culture. **Working hours: 2:00 PM to 11:00 PM.** Are you ready to join a team that transforms challenges into opportunities? Come with us! **Responsibilities and Duties** Capacity, Performance, and Availability Management * Continuously plan and adjust computing resource capacity (compute, memory, storage, network) on AWS and on\-premises—anticipating bottlenecks and avoiding waste. * Monitor, analyze, and optimize service and infrastructure performance—identifying degradations before they impact end users (applying USE and RED methodologies). * Define, implement, and maintain SLOs, SLAs, and error budgets—ensuring high availability through automation and well-documented runbooks. * Build and maintain automated controls that guarantee agreed-upon reliability KPIs with the business—including full traceability and auditability. Automation and Reliability Engineering * Develop and evolve operational automations—reactive and predictive scaling, automatic remediation, zero\-touch provisioning—to reduce toil and increase resilience. * Manage and optimize EKS clusters: provisioning, scalability (HPA / VPA / Cluster Autoscaler / Karpenter), networking, storage, and production workload troubleshooting. * Ensure versioned, reproducible, and auditable infrastructure. * Conduct chaos engineering to validate system resilience (controlled failure simulations, game days). Observability * Maintain complete observability stacks: metrics, logs, distributed tracing, and SLO\-oriented alerts. * Build dashboards and alerts using Prometheus, Grafana, and CloudWatch—with end\-to\-end visibility into infrastructure health. FinOps and Cost Management * Apply cloud cost optimization concepts and practices: rightsizing, reserved instances, savings plans, and spot instances. * Generate cost reduction reports and recommendations for AWS—using AWS Cost Explorer, Kubecost, or equivalent tools. * Implement tagging and chargeback mechanisms to enable cost visibility per service, squad, or product—fostering FinOps culture within the team. Incident Response and Technical Leadership * Participate in on\-call rotations, lead resolution of high\-severity incidents, and conduct blameless post\-mortems with concrete action items. * Support fellow SREs by disseminating reliability, observability, and operational engineering practices. * Serve as a technical reference for infrastructure architecture decisions related to reliability, capacity, and performance. * Collaborate with the cloud engineering team on infrastructure technical reviews. **Requirements and Qualifications** **Expected Technology Stack / Tools** **Core** **AWS Cloud:** EC2, Auto Scaling, EKS, Lambda, RDS/Aurora, S3 (lifecycle/tiers), EBS (gp3/io2\), EFS/FSx, VPC, Transit Gateway, ALB/NLB, Route53, IAM/SCP, CloudWatch, AWS Backup **Kubernetes / EKS:** EKS, Helm, Kustomize, HPA, VPA, Cluster Autoscaler, Karpenter, Network Policies, CSI Drivers, Persistent Volumes, Istio or Linkerd (desirable) **Storage — Cloud and On\-premises:** EBS (gp3/io2\), EFS, FSx, S3 lifecycle, CSI Drivers, SAN/NAS/NFS on\-premises, Ceph (desirable), AWS Backup, Commvault. **Infrastructure as Code:** Terraform, Ansible, CloudFormation **CI/CD and GitOps:** GitHub Actions, Azure DevOps, ArgoCD, Flux **Observability:** Prometheus, Grafana, Dynatrace or Datadog, CloudWatch, CloudTrail. **FinOps:** AWS Cost Explorer, Rightsizing, Reserved Instances, Savings Plans, Spot Instances. **On\-Premises:** VMware vSphere/ESXi, Bare\-metal Linux (Ubuntu, RHEL), Corporate Networks (VLAN, basic BGP/OSPF), Dell EMC / HPE (desirable) **Languages / Scripting:** Python, Bash/Shell. **Security (SRE\-scope):** IAM/SCP, RBAC in Kubernetes, Secrets Manager, Parameter Store, network policies. **Technical Competencies** * Solid experience managing capacity and performance in hybrid environments (cloud \+ on\-premises), with proven accountability for SLOs and KPIs. * Advanced expertise in AWS: compute, storage, networking, IAM, and managed services at production scale. * Production-grade Kubernetes/EKS: provisioning, troubleshooting, scaling, and storage—with minimum 4 years’ experience. * Production-level Terraform: modules, remote state, workspaces, and drift reconciliation. * End\-to\-end observability: metrics, logs, tracing, SLO\-oriented alerts, and operational dashboard creation. * Hybrid storage: deep knowledge of EBS, EFS, and FSx in cloud—and SAN/NAS/NFS on\-premises—including IOPS and capacity planning. * Python or Bash for automation and internal tooling. **Differentiators** * Multi\-cloud experience (AWS \+ Azure or AWS \+ GCP). * Production knowledge of service mesh (Istio or Linkerd). * Experience with FinOps tools (Kubecost, CloudHealth, Spot.io). * Participation in open source communities or meaningful contributions on GitHub. * Experience with event\-driven architecture (Kafka/MSK, SQS/SNS) in an SRE context. **Soft Skills** * Data\-driven, analytical thinking focused on reliability metrics and KPIs. * Clear and concise communication with technical teams and business stakeholders. * Autonomy and proactivity in highly complex and ambiguous environments. * Technical leadership without formal authority—exerting influence through expertise. * Resilience and focus under pressure during critical incidents. * Collaborative mindset and genuine willingness to mentor and share knowledge. **Certifications** Candidates must hold at least one certification in either SRE or AWS Cloud domains.
