Job Purpose:

An experienced endpoint engineer responsible for identifying the underlying causes of vulnerabilities, non-compliance and remediation failure across the TMHCC workstation estate. The role will design, test and deliver scalable fixes rather than rely on repeated manual intervention.

The EUP Engineer will use Qualys and other approved security data to prioritise risk, then apply strong packaging, SCCM/MECM, PowerShell and endpoint engineering skills to deliver controlled remediation. The role will improve deployment quality, endpoint health and operational efficiency by creating repeatable processes, automation and clear technical standards.

Direct business interaction is a key part of this role. The postholder will communicate technical risk and remediation plans clearly, manage stakeholder expectations and ensure agreed Service Level Agreements, quality thresholds and change controls are maintained.

Key Responsibilities:

• Own the technical investigation and remediation of complex endpoint vulnerabilities across the workstation estate.
• Analyse and prioritise findings from Qualys and other approved security platforms, considering technical impact, business risk and remediation feasibility.
• Perform structured root cause analysis for vulnerabilities, failed deployments, recurring non-compliance and endpoint health issues.
• Design sustainable engineering fixes that remove underlying causes and reduce repeated manual remediation.
• Create, test, peer review and deploy enterprise application packages, security updates and configuration changes through Microsoft SCCM/MECM and related endpoint tooling.
• Develop and maintain PowerShell automation for detection, remediation, validation, reporting and operational health checks.
• Troubleshoot SCCM/MECM client health, software distribution, content delivery, deployment status and patch installation failures.
• Use controlled pilot groups, technical validation and rollback planning to reduce deployment risk.
• Work with the End User Platform and Security teams to agree remediation strategy, technical ownership and delivery priorities.
• Recommend improvements to packaging standards, deployment controls, vulnerability workflows, reporting and endpoint engineering processes.
• Drive automation opportunities that improve remediation speed, consistency, evidence quality and operational efficiency.
• Identify recurring failure patterns and convert findings into permanent engineering actions, technical debt items or platform improvements.
• Produce clear technical documentation, remediation records, runbooks, knowledge articles and audit evidence.
• Provide accurate progress, risk and dependency updates for vulnerability, compliance and service reporting.
• Support remediation across physical workstations, laptops and Citrix virtual desktop environments.
• Lead complex endpoint problem investigations and provide senior technical guidance to support colleagues.
• Apply ITIL best practice across Incident, Request, Problem and Change management activities.
• Perform system administration and advanced troubleshooting within Windows, Active Directory, Group Policy and Microsoft 365 environments.

• Improve application, patch and security configuration deployment success across the managed estate.
• Reduce repeat vulnerabilities and failed remediation through effective root cause analysis and permanent fixes.
• Increase operational efficiency through automation, reusable packaging standards and repeatable processes.
• Improve SCCM/MECM client health, endpoint compliance and the quality of technical reporting and evidence.
• Deliver clear recommendations that lead to measurable improvements in current End User Technology processes.
• Deliver strong customer service while supporting wider 2nd line operational priorities.

• Strong application packaging and deployment experience, including testing, detection methods, dependencies, supersedence and rollback planning.
• Strong PowerShell skills with the ability to design, test, troubleshoot and maintain production-ready automation and remediation scripts.
• Experience analysing Qualys findings, or comparable vulnerability management data, and translating results into technical action.
• Good experience of Active Directory, Group Policy, Microsoft 365 and related endpoint technologies.
• Strong understanding of endpoint security, patch management, configuration compliance and change control principles.
