Your future role within QRT:
As a Hybrid EUC & Windows Platform Engineer, you will be part of the Global Infrastructure Team, responsible for designing, building, and supporting both Microsoft Windows Server / virtualization infrastructure and core End User Computing (EUC) services.
Your role is critical in ensuring the smooth operation of core IT services that underpin research technology, trading platforms, market execution, and data processing, while also ensuring a secure, consistent, and high-performing end-user experience across Windows endpoints, identity, and productivity services.
This role blends server platform engineering with modern EUC engineering, with a strong focus on Active Directory, Group Policy design, endpoint automation, and operational excellence.
Windows Server & Core Infrastructure Engineering
- Build, manage, and deploy Windows Server environments (2022–2025).
- Design, deploy, and support a globally distributed, multi-forest Active Directory environment.
- Configure and manage core AD services including DNS, replication, trusts, and identity integration with Entra ID.
- Manage user lifecycle processes within Active Directory, including provisioning, access controls, delegation, and role-based access models.
- Automate AD user and group management tasks, onboarding/offboarding workflows, and policy validation.
- Troubleshoot complex AD authentication, Kerberos, NTLM, and group membership issues impacting end users.
- Support infrastructure-as-code and configuration automation initiatives using PowerShell in combination with Ansible and Terraform where applicable.
- Build and manage VMware ESXi infrastructure, clustering, and virtualisation services.
- Optimise and troubleshoot server backups (e.g., Veeam) to ensure data integrity and disaster recovery readiness.
- Configure and maintain monitoring and observability tooling (e.g., Splunk) for performance and security visibility.
- Work with SAN/NAS storage platforms to ensure high availability and resilience.
- Provide 2nd-line support and act as 3rd-line escalation for Windows Server and infrastructure-related incidents.
End User Computing (EUC) & Endpoint Engineering
- Engineer, build, and optimise Windows 10/11 desktop environments across physical and virtual platforms.
- Support and optimise Citrix DaaS / VDI environments, including image management, GPO optimisation, and user experience tuning.
- Support and optimise Microsoft Intune, Entra ID, and Microsoft 365 services to deliver secure and consistent user experiences.
- Develop advanced PowerShell scripts to automate endpoint builds, software deployments, patch validation, and compliance reporting.
- Provide escalation support for EUC incidents affecting business-critical users, including performance, application compatibility, device compliance, and authentication.
- Identify recurring EUC issues and implement automation-based remediation strategies.
- Design and manage Group Policy Objects (GPOs) for endpoint configuration, security hardening, user environment control, and compliance enforcement.
- Own endpoint lifecycle processes including provisioning, configuration, patching, compliance, and decommissioning.
- Configure and manage endpoint security baselines across both Intune and Group Policy (co-management or hybrid scenarios where applicable).
- Build reporting and health-check scripts for endpoint compliance, patch levels, BitLocker status, and device posture.
- Troubleshoot profile management, FSLogix, login performance, and policy conflicts in virtual environments.
- Drive standardisation across Windows Server builds, endpoint baselines, GPO structures, and Citrix images.
- Maintain technical documentation including AD design, GPO standards, endpoint baselines, and automation frameworks.
- Provide cross-functional troubleshooting support across infrastructure, networking, storage, security, and cloud teams.
- Stay informed about emerging Windows platform, EUC, and identity technologies to identify strategic improvement opportunities.
Your present skillset (ideal candidate profile)
- Extensive experience designing and supporting Windows Server and enterprise AD environments.
- Strong hands-on expertise in Active Directory architecture, GPO design, DNS, replication, and identity troubleshooting.
- Advanced PowerShell scripting skills for both server and EUC automation, including AD and endpoint management.
- Deep understanding of Windows 10/11 enterprise builds, hardening, and lifecycle management.
- Experience managing Microsoft Intune, Entra ID, Microsoft 365, and hybrid identity environments.
- Experience supporting and optimising Citrix DaaS / VDI environments.
- Experience with VMware ESXi, clustering, and virtual infrastructure.
- Experience with backup platforms such as Veeam.
- Strong knowledge of networking fundamentals, PKI/certificate services, and infrastructure security.
- Strong troubleshooting capability across server, endpoint, identity, and virtual desktop layers.
- Excellent communication skills with the ability to work independently and collaborate across global teams.
