Infrastructure Engineer

Gradera; Hyderabad; On-site; INR 400,000 - 800,000; Full time

Job summary

Gradera is seeking a high-caliber Infrastructure Engineer to join our Security & DevSecOps squad. You will translate architectural visions into robust, executable OpenShift cluster designs for on-premises hardware, including storage and networking across bare-metal OpenShift deployments.

The role requires independent problem-solving, deep OpenShift expertise, and hands-on administration of OCP, ODF, and virtualization.

Qualifications

• 6 to 8 years of infrastructure engineering or systems administration experience.
• Expert-level OpenShift Administration on bare-metal/on-prem environments.
• Strong RHEL system administration and performance tuning.
• Hands-on with OpenShift Data Foundation (ODF) and OpenShift Virtualization.
• Experience with OVN-Kubernetes networking and security constructs (SCC/RBAC).
• Ability to work independently on complex hardware-to-software integration.
• Familiarity with monitoring and disaster recovery planning (Prometheus/Grafana).

Responsibilities

• Convert blueprints into detailed cluster specs including IPAM, storage topology and VLAN tagging for bare-metal OCP.
• Lead bare-metal OpenShift installation, scaling, and lifecycle management on physical hardware.
• Architect and manage OpenShift Data Foundation (ODF) storage for highly available databases.
• Design and troubleshoot OVN-Kubernetes network patterns for secure, low-latency communication.
• Lead OpenShift Virtualization migration of legacy VM workloads into OpenShift.
• Implement and enforce SCC and RBAC policies for secure cluster operations.
• Establish monitoring with Prometheus/Grafana and plan Disaster Recovery scenarios.
• Act as final escalation for performance, networking, or storage failures.

Job description

Overview

We are seeking a high-caliber Infrastructure Engineer to join our Security & DevSecOps squad. In this role, you will translate architectural visions into robust, executable designs for on-premises OpenShift clusters and underlying hardware abstractions. We are looking for a systems expert who can work independently to manage the complexity of bare-metal OpenShift deployments and mission-critical storage.

Our Core Infrastructure Stack

OpenShift Platform & Virtualization

• OpenShift Container Platform (OCP) administration on bare-metal/on-prem environments

• OpenShift Virtualization for managing VM-based workloads alongside containers

• RHEL (Red Hat Enterprise Linux) advanced system administration and performance tuning

  Networking & Storage

• OpenShift Networking (Software Defined Networking / OVN-Kubernetes)

• OpenShift Data Foundation (ODF) for persistent, software-defined storage

• Load balancing, ingress controllers, and DNS management within a restricted network

  Security & Observability

• Cluster Security (Security Context Constraints (SCC), RBAC, Network Policies)

• Monitoring & Alerting (Prometheus, Grafana, and Alertmanager)

• Disaster Recovery (DR) and high-availability (HA) planning for stateful workloads

• Knowledge of Infrastructure as Code (Ansible/OpenTofu) for cluster day-2 operations.

Key Responsibilities

• Convert high-level blueprints into detailed cluster specs, including IP address management (IPAM), storage topology, and VLAN tagging for bare-metal OCP.

• Bare-Metal Administration: Independently lead the installation, scaling, and lifecycle management of OpenShift on physical hardware, including firmware updates and node provisioning.

• Storage Orchestration: Architect and manage OpenShift Data Foundation (ODF), ensuring persistent storage is highly available and performant for simulation databases.

• Network Engineering: Design and troubleshoot complex OVN-Kubernetes network patterns, ensuring secure and low-latency communication between simulation services.

• OpenShift Virtualization: Lead the migration and management of legacy VM workloads into OpenShift, providing a unified control plane for the digital twin ecosystem.

• Cluster Security Hardening: Implement and enforce strict SCC and RBAC policies, ensuring the platform complies with global security benchmarks and the squad's DevSecOps standards.

• Monitoring & DR: Establish comprehensive monitoring with Prometheus/Grafana and independently design and test Disaster Recovery scenarios to ensure zero-data-loss targets.

• Autonomous Troubleshooting: Act as the final escalation point for cluster-level performance issues, networking bottlenecks, or storage failures, resolving them without external guidance.

Preferred Qualifications

• 6 to 8 years of experience in Infrastructure Engineering or Systems Administration.

• Expert-level mastery of Red Hat OpenShift (OCP); Red Hat Certified Specialist in OpenShift Administration/Automation is highly preferred.

• Deep experience in Bare-Metal deployments and RHEL administration.

• Hands-on proficiency with OpenShift Data Foundation (ODF) and OpenShift Virtualization.

• Strong understanding of Kubernetes Networking (SDN/OVN) and security constructs (Network Policies).

• Demonstrated ability to work independently on complex hardware-to-software integration projects.

Highly Desirable

• Experience supporting high-compute Digital Twin or Simulation environments.

• Experience with backup solutions for OpenShift (Velero or OADP).

• Experience in managing on-premises infrastructure for global product engineering hubs.

• Exposure to industrial domains such as Manufacturing, Logistics, or Transportation is a plus.

• Exposure to CI/CD and platform automation tools such as GitHub Actions, Jenkins, or GitOps practices to better align with DevSecOps operating models.

• Hybrid-cloud exposure (AWS, Azure, or GCP) as a preferred qualification
