Job Overview:
Requirement/Must Have: 10+ years of IT experience, including 5+ years in platform engineering, infrastructure operations, Dev Ops, or patch management. Experience managing enterprise-scale patching activities across Linux and Windows operating system platforms. Proven ability to design, test, certify, and release infrastructure or platform changes in production environments. Strong knowledge of OS patch engineering, patch catalogues, patch validation, release readiness, and lifecycle management.

Hands-on experience with Linux platforms such as RHEL, Rocky Linux, Ubuntu, Alpine, or similar distributions.

Experience with Windows Server patching, operating system maintenance, and enterprise platform support. Strong scripting experience using Python, Bash, Power Shell, Groovy, or similar automation languages.

Experience with CI/CD tools such as Git Hub Actions, Jenkins, or equivalent platforms.

Experience with configuration management and automation tools such as Ansible, Terraform, or similar technologies. Hands-on experience with cloud platforms, preferably Google Cloud Platform (GCP), with Azure or AWS experience beneficial. Knowledge of container platforms including Docker, Kubernetes, GKE, Open Shift, or similar technologies. Understanding of cloud-native deployment patterns, image lifecycle management, and platform reliability practices. Strong understanding of vulnerability management, security hardening, compliance controls, and audit support.

Experience working with cybersecurity, risk, and operations teams to remediate vulnerabilities and improve platform compliance. Ability to prepare evidence and support governance activities related to patching and platform operations. Responsibilities:
Design, test, certify, and maintain operating system patching solutions, patch catalogues, and platform enhancements. Support OS patch engineering, patch tooling integration, and automation capabilities across infrastructure and cloud platforms. Validate, test, and release patches to meet production, compliance, security, and operational requirements. Manage patch lifecycle activities, including patch availability, validation outcomes, release readiness, and operational handover. Develop and maintain engineering standards, procedures, and documentation related to patch governance and platform maintenance.

Integrate vulnerability assessment, security validation, and compliance checks into patch management and platform engineering processes. Ensure operating system and platform configurations comply with internal policies, regulatory expectations, risk controls, and audit requirements. Collaborate with cybersecurity and risk teams to assess vulnerabilities, prioritize remediation, and strengthen the security posture of infrastructure platforms. Support compliance evidence, operational reporting, and audit activities related to patching, platform maintenance, and vulnerability remediation.

Develop automation for patch deployment, validation, rollback checks, monitoring, reporting, and release readiness activities. Use Infrastructure as Code, configuration management, and scripting to reduce manual effort and improve repeatability across patching operations. Identify opportunities to optimize patching processes, improve release frequency, and support timely vulnerability remediation. Contribute to standardization of tools, processes, and engineering patterns across infrastructure platforms. Act as a technical point of contact for platform, infrastructure, security, application, and operations teams.

Work with stakeholders to understand patching requirements, production dependencies, service constraints, and compliance expectations. Provide technical guidance and best practices for patch governance, automation, platform stability, and release management. Operate effectively within a cross-functional Agile team, contributing to knowledge sharing, mentoring, and engineering excellence.
