An established financial services organisation is seeking an experienced IT Support Engineer to provide comprehensive IT support and infrastructure services within its London branch. The role will be responsible for supporting staff and high-net-worth clients, maintaining the branch's IT infrastructure, responding to service outages and incidents, and ensuring the security, resilience and availability of critical IT systems.

You will be expected to assist with incident management, including monitoring, investigation, resolution and post‑incident follow‑up, as well as supporting monthly infrastructure testing and risk assessment activities.

The role has a strong focus on cybersecurity, operational resilience, data integrity and regulatory compliance. You will support the implementation of appropriate security controls, patching practices, backup and disaster recovery procedures, and assist with the development of cybersecurity and operational resilience guidance and procedures. You will also be expected to work within the regulatory framework applicable to a UK‑regulated bank, maintaining high standards of integrity, professionalism, confidentiality, governance and customer protection.

The successful candidate will ideally have a Bachelor's or Master's degree, or relevant professional qualification, in IT, Information Systems, Computer Science, Computing, Technology, Programming, Information Science or a related discipline. At least three years' IT experience is required, ideally gained within the banking or wider financial services sector. You should have strong hands‑on troubleshooting experience across Windows, Microsoft Office and conferencing applications, together with a good understanding of IT infrastructure and end‑user computing.

Technical experience should include Windows 11, Linux, Windows Server 2016 or later, Microsoft 365, OneDrive, Teams, SharePoint, Active Directory, Group Policy and Windows imaging. Experience with financial services applications and platforms such as Bloomberg, Murex, SWIFT, Refinitiv and other banking systems would be highly advantageous. Knowledge of SQL Server, Veeam, backup technologies and relevant financial or operational systems would also be beneficial.

You should have a good understanding of networking fundamentals, including DNS, DHCP, TCP/IP and LAN/WAN, together with exposure to VMware environments, FortiGate firewalls and Cisco networking equipment. Experience with endpoint protection, patch management, infrastructure monitoring, backup and recovery solutions and security controls will be important. The role may also involve elements of data analysis, reporting, programming and project management, so a broad technical skill set would be beneficial.

Alongside your technical expertise, you will need strong interpersonal, written and verbal communication skills, with the ability to work effectively with staff, senior stakeholders, Group IT teams, security functions, auditors and external parties. You should be comfortable working in a fast‑paced and highly regulated environment, prioritising incidents according to business impact and providing a professional and customer‑focused service.

This is an excellent opportunity for an IT professional looking to take on a broad infrastructure and support role within a highly regulated financial services environment, with exposure to banking technology, cybersecurity, operational resilience, infrastructure, business continuity and critical business systems.
