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.

- Robust 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
