Job description

Job Information:

• Functional Title: End User Support Specialist
• Department: Digital Workspace
• Reports To: Vice President, Infrastructure End User Support

A Senior Associate role for an Infrastructure End User Support Specialist who can lead escalations, mentor colleagues, support modern endpoint management, and help launch our new Technology Bar.

Overview of the role:

CLS is modernizing the way technology is delivered to colleagues. We are moving further into a Windows 11 and Microsoft Intune managed estate, reducing reliance on legacy endpoint tooling, and opening a new Technology Bar in our refurbished London office. We are looking for a highly experienced Senior Desktop Support Engineer to become the senior technical member of our London End User Computing team. This is more than a traditional desktop role: you will be the person the team turns to for complex escalations, practical judgement, coaching, technical standards and service improvement. The role combines hands‑on support, endpoint engineering, technical leadership, hardware service capability and project contribution. It is ideal for someone who wants to influence how an End User Computing function operates rather than simply work through a ticket queue.

What you will be doing:

How you will spend your time

• Desktop Support - 45% - Senior escalations point for Windows 11, Microsoft 365 collaboration technologies, meeting rooms, executive support and complex incidents.
• Endpoint Engineering - 25% - Intune, Autopilot, application development, endpoint compliance, hardware standards and device lifecycle management.
• Technology Leadership - 20% - Mentoring engineers, leading investigations, improving documentation, setting standards and acting as the senior technical voice of the team.
• Continuous improvements & innovation - 10% - Technology Bar development, automation of processes, Windows 11 rollout support, process optimization and measurable service improvements.

What we are looking for:

We are not looking for someone who only resolves individual tickets. We are looking for someone who asks why the issue happened, whether it will happen again, how the team can prevent it, and what can be improved so the next user has a better experience.

Key Technologies include:

• Windows 11
• Hardware vendor warranty tooling
• Microsoft 365
• Exchange Online
• Microsoft Teams
• OneDrive
• Active Directory
• ServiceNow
• PowerShell

Secondary / legacy technologies

• SCCM - Supporting the transition to Intune
• Citrix - Supporting the virtualized environment

Our commitment to employees:

We are a small company with a big mandate, so every person is essential to our success. We are also committed to employing and retaining the most talented and dedicated people.

What makes us interesting goes beyond our competitive salaries and great benefits. Our work environment is designed around quality outcomes, not output. The FX market would cease to function without our services, and we take pride in being responsible for keeping it running smoothly.

We are different from other financial institutions in that we have a flatter and more transparent structure with accessible leadership. You will be seen, heard and empowered to develop your career.

We are a purpose-driven organization, with an inclusive culture that focuses on doing what is right. The well‑being of our people is as important to us as the resilience of our systems. In addition to encouraging our people to ‘locate for their day,’ we run a range of initiatives that support employees’ sense of belonging and physical, emotional and mental well‑being.
