Infrastructure Engineer

Gradera Inc.; Hyderabad; On-site; INR 900,000 - 1,400,000; Full time

Job summary

PVH is seeking an Infrastructure Engineer to join the Security & DevSecOps squad. You will translate architectural visions into robust, executable designs for on-premises OpenShift clusters and hardware abstractions. This role focuses on bare-metal OCP, ODF, and virtualization within a restricted network environment.

Ideal candidates have deep OpenShift, RHEL, storage, and networking expertise, with independence for hardware-to-software integration in mission-critical environments.

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.

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.

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.

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.

• 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.
