Who we are
Panmure Liberum is a leading independent investment bank. Our integrated business brings together investment banking, research, institutional sales and execution services for quoted companies, growth businesses and institutional investors. We advise more UK public companies than any other independent investment bank, drawing on specialist sector knowledge, strong investor relationships and extensive public-markets expertise.
The role
We are looking for an experienced Desktop & Infrastructure Engineer to join our London-based IT team on an initial 6-month fixed-term contract.
Reporting to the Head of Infrastructure, this is a broad, hands-on position combining high-quality desktop support with responsibility for the stability, security and performance of our IT infrastructure.

The role will support employees at all levels of the firm. Strong technical expertise, excellent communication skills and a responsive, service-focused approach will therefore be essential.

- Provide responsive and professional desktop support to employees and senior stakeholders
- Administer and support Microsoft 365, Windows, Active Directory and Entra ID environments
- Support endpoint configuration, software deployment, patching and device management
- Maintain and troubleshoot servers, networks, virtual environments, storage and cloud services
- Monitor infrastructure availability, capacity, performance and security
- Support backup, recovery, antivirus and business-continuity processes
- Manage user access, permissions and security controls in line with the firm’s policies
- Support meeting-room technology, mobile devices and remote-access solutions
- Own incidents through to resolution and undertake root-cause analysis for recurring issues
- Maintain accurate asset records, technical documentation and operational procedures
- Liaise with third-party suppliers and technology partners
- Support infrastructure changes, upgrades and improvement initiatives
- Identify opportunities to improve system reliability, security and the overall user experience
- Provide wider desktop and operational IT support when required
