Sr DevOps Engineer

Job Summary

This is a hands-on execution role on a live network. Youll be running deployments, upgrades, and changes across pre-production and production Kubernetes clusters - following documented procedures precisely, verifying results, and escalating quickly when something doesnt match expected outcomes. Our production clusters carry live traffic for operator partners at a 99.999% availability bar. Discipline matters more here than invention: doing the documented thing correctly, at 2am, on the fifth cluster in a sequence, with the same care as the first.

Key Skills

• Kubernetes
• AWS
• GCP
• Terraform
• Ansible
• Python
• Bash
• CI/CD
• Prometheus

Responsibilities

• Execute deployments, rollouts, and rollbacks across pre-production and production Kubernetes clusters, following documented runbooks and change-management procedures
• Run cluster upgrades and node lifecycle operations in a defined sequence, validating health at each gate before proceeding
• Promote changes through environments in order - dev to pre-prod to production - and verify each stage
• Work within approved change windows and maintenance schedules, with escalation paths and rollback plans prepared in advance
• Keep pre-prod a faithful mirror of production, and flag drift between them as a defect
• Participate in a follow-the-sun on-call rotation covering IST hours alongside global teams
• Respond to alerts using established runbooks: triage, mitigate, escalate to the on-call engineer or SME when the runbook runs out
• Communicate clearly during incidents - status, impact, actions taken, and what is needed
• Automate repetitive parts of the operational workload - scripts, pipeline steps, Ansible/Terraform changes - within established team patterns
• Improve runbooks as you execute them; fix unclear or incorrect procedures while they are fresh
• Log every production change accurately with what was done, when, by whom, and verification results

Requirements

• 5+ years in DevOps, SRE, infrastructure, or production operations roles, with substantial time operating production systems
• Solid hands-on Kubernetes operations: deployments, rollouts, troubleshooting pods and nodes, reading logs and events to isolate faults under pressure
• Working experience with AWS and GCP in a production context
• Comfortable with infrastructure as code and configuration management (Terraform, Ansible, or equivalent)
• Scripting proficiency in Python or Bash sufficient to automate operational tasks
• Demonstrated production on-call experience in a change-controlled environment with formal change processes
• Linux systems fundamentals: networking, storage, processes, systemd, performance basics
• Precision and follow-through: read procedures fully before starting, verify rather than assume, and escalate immediately when something looks wrong

Nice to Have

• Telecom domain knowledge - 5G core, cloud-native network functions, IMS, or telecom operations
• Experience managing databases and applications with 99.999% high availability
• Observability tooling: Prometheus, Grafana, ELK - building dashboards and tuning alerts operationally
• GitOps workflows (ArgoCD, Flux) and progressive delivery
• Edge or on-premises infrastructure alongside public cloud, particularly sites with constrained connectivity
• Formal change management or ITIL-style process experience
• FinOps and cloud cost awareness in day-to-day operational decisions
