Devops Engineer

Job Title: Devops Engineer Location: Mumbai Experience: Employment Type: Full-Time About Oneture: Oneture is building intelligent, cloud-native solutions that drive real business impact. We are looking for a passionate Senior Data Scientist to join our growing team and lead predictive modeling initiatives. About the Role: Oneture Technologies is looking for a hands-on DevSecOps / Platform Engineer to join an on-site, air-gapped on-premise Kubernetes engagement. The platform underpins a mission-critical, security-hardened system and runs entirely on-premise across bare-metal infrastructure — this is not a cloud-first role. The engineer will own day-to-day cluster operations, CI/CD tooling, and observability across Production, DR, and UAT environments. Key Responsibilities • Own and operate the on-premise Kubernetes clusters across PR, DR, and UAT — upgrades, patching, capacity, and incident response. • Build and maintain on-prem CI/CD pipelines and secure air-gapped deployment workflows. • Implement and maintain the Prometheus/Grafana monitoring stack and an on-prem logging solution, with alerting for critical workloads. • Work closely with application and data teams (streaming, database) to keep the platform secure, available, and performant. • Document infrastructure, runbooks, and troubleshooting procedures for a security-hardened, air-gapped setup. Primary Skills: Must Have: 1.On-Premise Kubernetes (End-to-End): • Proven hands-on experience installing, configuring, and operating a Kubernetes cluster entirely on-premise / bare-metal (e.g. RKE2, kubeadm, k3s) — not managed/cloud K8s (EKS/GKE/AKS). • Strong grasp of on-prem-specific components: CNI (e.g. Calico), MetalLB or equivalent for bare-metal load balancing, ingress controllers, and persistent storage (e.g. Longhorn, local-path-provisioner). • Experience managing multi-node clusters across Production, DR, and UAT with high-availability and DR failover considerations. • Comfortable troubleshooting at the cluster, node, and container-runtime level (e.g. containerd) in a fully air-gapped environment 2. On-Premise DevSecOps Tooling [MANDATORY] : • Experience standing up and administering CI/CD tooling on-premise — Jenkins or equivalent (GitLab CI, Tekton, etc.), fully self-hosted with no external/SaaS dependency. • Ability to design secure, air-gapped CI/CD and artifact/image workflows (e.g. offline image transfer and import pipelines) where the environment has no direct internet access. • Working knowledge of security hardening for on-prem environments — access controls, sudo/user policy restrictions, firewall and network segmentation across subnets. 3. On-Premise Monitoring & Logging [MANDATORY] • Hands-on experience deploying and managing a self-hosted monitoring and alerting stack — Prometheus and Grafana at minimum. • Experience with an on-prem logging/log-aggregation stack (e.g. Loki, ELK/EFK, or equivalent) for cluster and application-level observability. • Ability to build actionable dashboards and alerts for cluster health, node resource usage, and workload-level metrics without relying on cloud-native/SaaS monitoring tools. 4. Linux Fundamentals [MANDATORY] • Strong Linux administration skills (RHEL/CentOS preferred) — Kubernetes runs on Linux, and day-to-day troubleshooting happens at the OS level. • Comfortable with systemd, networking (iptables/nftables, routing), storage/disk management, and package management in an offline/air-gapped context. • Solid shell scripting ability for automation and troubleshooting.
