JD- Devop’s Manager
Key Responsibilities
DevOps & Infrastructure:
- Build and manage CI/CD pipelines using Jenkins (declarative/scripted pipelines,
multibranch, shared libraries) and implement GitOps-based delivery with ArgoCD
(auto-sync, rollbacks, Helm/Kustomize integration)
- Deploy and orchestrate containerized services using Docker and Kubernetes
(StatefulSets, Deployments, Ingress, HPA, RBAC, network policies)
- Deploy production databases on Kubernetes using StatefulSets with master-slave
architecture:
PostgreSQL (streaming replication, PgBouncer, WAL archiving, PITR backups)
MongoDB (replica sets, sharding, oplog-based recovery)
Redis (Sentinel for HA, Redis Cluster, RDB/AOF persistence)
- Implement automated database backup strategies with scheduled jobs, offsite
storage (S3/Azure Blob), retention policies, and restore drills
- Manage cloud infrastructure on AWS (EC2, VPC, EKS, IAM, S3, Route53) and/or
Azure (VMs, AKS, VNet, NSG, Blob Storage)
- Configure Linux networking: iptables/nftables rules, static/dynamic routing (ip
route), NAT/PAT, firewall policies, VLAN tagging
- Perform disk partitioning (LVM, fdisk, parted), filesystem management, RAID setup,
and storage capacity planning
- Write automation scripts in Shell (Bash) and Python for provisioning, deployments,
backups, and monitoring
- Manage infrastructure as code using Terraform and Ansible; set up monitoring with
Prometheus, Grafana, and ELK stack
DevOps Skills:
- Docker & Kubernetes: image builds, Compose, container networking, StatefulSets,
Helm charts, Ingress, RBAC, autoscaling, cluster troubleshooting
- CI/CD & GitOps: Jenkins (pipelines, shared libraries, webhooks, credentials), ArgoCD
(Git sync, rollbacks, multi-cluster, health checks), Git branching strategies
- Databases (deploy, replicate, backup, tune):
PostgreSQL — master-slave replication, PgBouncer, pg_dump/pg_basebackup,
PITR, query tuning
MongoDB — replica sets, sharding, mongodump/mongorestore, oplog recovery,
indexing
Redis — Sentinel, Cluster, RDB/AOF persistence, eviction policies, pub/sub
- Shell Scripting: advanced Bash (loops, functions, error handling), log parsing, cron
jobs, systemd services; text processing with awk, sed, jq
- Python: infrastructure automation (Boto3, Azure SDK), API integrations,
backup/monitoring scripts, Jinja2 templating
- Cloud: AWS (EC2, VPC, IAM, EKS, S3, ALB, Route53, CloudWatch) and/or Azure (AKS,
VNet, NSG, Key Vault, Azure Monitor)
- Networking: iptables (chains, NAT, DNAT/SNAT, port forwarding), ip route,
subnetting/CIDR, DNS, TCP/IP, load balancing (L4/L7), VPN, troubleshooting
(traceroute, mtr, ss, tcpdump)
- Storage: LVM, fdisk/parted, ext4/xfs, fstab, RAID (mdadm), NFS
- IaC & Monitoring: Terraform (modules, state, workspaces), Ansible (playbooks,
roles, vault), Prometheus, Grafana, Alertmanager, ELK/EFK
- Linux Admin: Debian/Ubuntu/CentOS/RHEL, systemd, process management,
security hardening
