Hi,

Exp: 3-4 Years

As a DevOps Engineer you’ll be responsible for deploying, managing, and troubleshooting our on-prem platform across customer datacentres. We’re looking for someone with hands-on experience across self-managed databases, Linux and networking, Kubernetes operations, and Ansible automation. You’ll also own production issues and work closely with customer infrastructure, network, and security teams.

Key Responsibilities

· Deploy and upgrade Java/Spring Boot services on Kubernetes clusters inside customer datacentres, using Helm with per-customer value sets.

· Manage the Kubernetes clusters themselves — installation and version upgrades, node lifecycle and capacity, control-plane and etcd health, certificate rotation, CNI, ingress and storage classes — both on clusters we build and on enterprise distributions the customer provides.

· Provision, tune and operate self-managed databases on Linux VMs — MySQL, PostgreSQL and MongoDB — including replication, backup, verified point-in-time restore, and version upgrades.

· Provision and operate the middleware layer on VMs — Redis (Sentinel), Apache Kafka and RabbitMQ — including clustering, authentication and capacity planning.

· Run OpenSearch as the centralised application log store: shard and heap sizing, index lifecycle and retention policies, cluster health.

· Automate the full infrastructure build with Ansible — reusable roles plus per-customer inventories, so the same automation installs the stack at every customer without being forked.





· Own day-2 Kubernetes operations: rollouts, probe and resource tuning, persistent storage, ingress and TLS, and diagnosis of pod, scheduling and networking failures.

· Troubleshoot production issues across the VM, network, Kubernetes and JVM boundaries — determine whether a fault is infrastructure or application, and drive root-cause analysis.

· Debug connectivity problems at the command line: routing, firewalls, DNS, MTU, TLS chains and certificate trust, packet capture.

· Manage certificates, truststores and private container registry (Harbor) content for restricted and air-gapped environments.

· Monitor the platform using Prometheus, Grafana and OpenSearch — define what gets alerted on, not only what gets dashboarded.

· Write Python and Shell automation for provisioning, health checks and routine operational tasks.

· Apply security and access hygiene appropriate to regulated customer environments — least privilege access, secret handling, network segmentation, audit readiness.

· Produce and maintain runbooks and handover documentation so a customer's own operations team can run what we install.

· Work directly with customer infrastructure, network and security teams during deployment and issue resolution, in office where required.

· Collaborate with development and QA teams to plan and execute releases.

· Support periodic out-of-hours deployment and upgrade windows at customer
