Job summary

Oneture Technologies is seeking a hands-on Senior Data Scientist? and Platform Engineer to join our team and lead predictive modeling initiatives while also owning on-premise Kubernetes operations.

The role focuses on managing bare-metal clusters, air-gapped CI/CD pipelines, and secure, observable infrastructure. The ideal candidate will have proven experience installing and operating on-prem Kubernetes (RKE2/kubeadm/k3s), strong Linux system administration, and expertise in securing air-gapped

Qualifications

• Proven hands-on experience installing, configuring, and operating a Kubernetes cluster entirely on-premise / bare-metal (e.g. RKE2, kubeadm, k3s).
• Strong grasp of on-prem components: Calico, MetalLB, ingress controllers, and persistent storage (Longhorn, local-path).
• Experience managing multi-node clusters across Production, DR, and UAT with high-availability and DR failover.
• Troubleshooting at cluster, node, and container-runtime level (containerd) in fully air-gapped environments.
• Experience standing up and administering on-prem CI/CD tooling (Jenkins, GitLab CI, Tekton) self-hosted with no external SaaS dependency.
• Design secure air-gapped CI/CD and artifact/image workflows with no internet access in the environment.
• Security hardening for on-prem environments — access controls, sudo policies, firewall and network segmentation.
• Hands-on experience deploying and managing a self-hosted monitoring and alerting stack (Prometheus/Grafana) on-premises.
• Experience with on-prem logging/aggregation (Loki, ELK/EFK) for cluster/application observability.
• Ability to build actionable dashboards and alerts for cluster health and resource usage without cloud-native tools.
• Strong Linux administration (RHEL/CentOS preferred) with offline context.
• Shell scripting for automation and troubleshooting.

Responsibilities

• Own and operate on-premise Kubernetes clusters across PR/DR/UAT — upgrades, patching, capacity, incident response.
• Build and maintain on-prem CI/CD pipelines and secure air-gapped deployment workflows.
• Implement and maintain Prometheus/Grafana monitoring stack and on-prem logging solution with alerts.
• Collaborate with application/data teams to keep platform secure, available, and performant.
• Document infrastructure, runbooks, and troubleshooting procedures for air-gapped setup.

Job description

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:

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

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.

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.
