They will work with internal and third-party vendors/service providers, ensuring seamless integration, effective service delivery, and alignment with strategic objectives. 

What You Will Do:  

OpenShift Platform Build & Operations (On Prem)

• Build, maintain, and operate a production OpenShift platform on prem, including cluster/node lifecycle, operators, and platform stability responsibilities.

• Execute measured, low risk platform configuration changes in production (e.g., routing/ingress/TLS policy changes) with controlled rollouts. 

• Manage platform configuration changes and upgrades using operator driven, controlled rollouts aligned with change management practices.

• Operate OpenShift Service Mesh (Istio based) to enable secure, observable service to service communication.

• Manage mesh control plane lifecycle via Operators and CRDs.

• Support traffic management (routing, canary releases, rate limiting), zero trust security (mTLS, workload identity), and observability (metrics, logs, tracing).

• Understand and operate sidecar and ambient (sidecar less) modes as appropriate to platform requirements.

• Understanding of cloud (AWS in particular) and SaaS platform services such as SES and IDAM/CIAM. 

• OS & Host Foundations Supporting Container Platforms

• Senior capability administering RHEL (Windows Server, nice to have) underlying supporting components and adjacent services (patching, stability, software currency).

• Support minor/major upgrades, extensions to databases: CockroachDB , EDB Postgres/PostgreSQL

• Facilitate patching activities and forward/rollback testing in lower environments to reduce production risk.

​Docker Containerization & Image Lifecycle

• Build and troubleshoot Docker images used for OpenShift workloads, including authoring and maintaining Dockerfiles, multib7stage builds (where required), and image reproducibility.

• Strong competency managing base images and 2golden image2 practices (selecting approved bases and ensuring they are updated with security fixes

• Enforce and troubleshoot nonb7root container execution expectations (e.g., Dockerfile USER and runtime permissions constraints) consistent with enterprise cluster deployment standards.

• Manage and validate image runtime behavior (filesystem permissions, readb7only constraints where feasible, and container startb7up failures linked to image construction).

• Container Registry, Artifact, and Supplyb7Chain Management

• Operate and integrate artifact and container image repositories that support OpenShift deployments (pull/push flows, promotion patterns, availability during releases).

• Support and troubleshoot binary/image scanning workflows and address findings that block deployments.

CI/CD & Automation for Container Delivery into OpenShift

• Operate CI/CD pipelines that build Docker images, publish artifacts, and support deployment workflows (pipeline troubleshooting that impacts releases and platform stability).

• Automation-first capability using Ansible, Bash, and Python to reduce manual toil in container build/release and operational tasks.

• Maintain environment synchronization across deployments (application versions, configuration, and certificates) so container releases are consistent across lower/prod environments.

• Mapped technologies: GitHub(GitActions), Jenkins, SonarQube, JFrog Artifactory, JFrog Xray

• Ingress / Routing / TLS & Certificate + Key Management (Platform Edge Controls)

• Operate API ingress and routing tiers and apply safe config changes (including TLS policies) with measured rollouts.

• Strong knowledge of certificate and key management, including troubleshooting cert issues impacting routing, mTLS/TLS handshakes, and platform/application deployments.

• Manage certificate and key lifecycles affecting platform and service connectivity.

• Coordinate with network and security teams to troubleshoot northb7south and eastb7west traffic issues

Observability, Alerts, and Operational Signal Quality

• Maintain platform dashboards and alerts, including tuning thresholds to minimize false positives while maintaining detection fidelity.

• Perform ongoing monitoring and capacity management for infrastructure and software platforms supporting OpenShift service levels.

• Reliability, Incident Response & Change Management (Senior Ops Competence)

• Partner on incident bridges to quickly differentiate platform vs application faults and restore service.

• Meet high availability expectations aligned to defined SLA/SLO for critical systems.

• Working knowledge of ITIL-aligned change management: maintenance window planning and rollback engineering.
