We are focused on teamwork, and our people collaborate on all aspects of the business, working openly and with respect for each other, our clients and the market.

We exhibit special expertise in automation (predominantly in PowerShell, but also in python and other languages). 

We currently operate 4 days a week in-office, 1 from home.

Responsibilities

• You will support our employees in their day-to-day use of the computer systems in our Bristol Office and offer remote support to other European offices as required.
• Perform day-to-day operations, support, and maintenance of our IT platform and cloud applications, including (but not limited to): Microsoft 365, Slack, Active Directory, Jira, VC Estate and other IT related systems.
• Co-own and continuously improve the onboarding processes for both users and hardware in the Bristol office.
• Co-Manage IT asset tracking and lifecycle processes (procurement, deployment, refresh, and disposal).
• Contribute to the global Windows platform, supporting standardisation, optimisation, and continuous improvement.
• Diagnose and resolve issues across:
  • Windows desktops and servers.
  • Active Directory and Entra ID.
  • Hardware and peripherals.
• Develop and maintain automation solutions to improve efficiency and scalability, including:
  • Automated builds and provisioning.
  • Configuration management.
  • Patch management and application deployment.
  • Monitoring, observability, and performance tooling.

Once fully integrated into the business, there is an on-call rota to provide IT coverage, this includes occasional weekend support/maintenance tasks. Approximately once every 6 weeks with time off in lieu the following week.
 

Essential Attributes

We estimate that you will have at least 5 years’ experience in a relevant technical role and you will have many of the following technical skills:

• Relevant experience administering Windows environments, including:
  • Active Directory.
  • Microsoft 365, Entra ID (Identity, Intune, Purview, Exchange, Teams, …).
  • Windows 11, Windows Server (2019 / 2022 / 2025).
• Solid PowerShell scripting skills for automation.
• Experience with endpoint management tools:
  • SCCM.
  • Microsoft Intune (OS and application deployment/management).
• Familiarity with Linux command line environments.
• Working knowledge of version control systems (e.g., Git).
• Basic understanding of networking concepts and Cisco CLI commands.
• High proficiency with Microsoft Office applications.
• Due to the nature of the role, you will be occasionally required to move, lift, rack and install equipment (pc’s, switches, servers).

As this role involves regular interaction with, and providing support to our employees, we are seeking an individual that is:

• Personable and enthusiastic with a genuine desire to enable staff to take full advantage of their IT systems.
• Able to explain technical concepts and events to non-technical staff members.
• Articulate, numerate and capable of negotiating high value technology equipment and services.
• Able to reason logically and consistently deliver under pressure.
• Able to spot new opportunities and follow through with them.

Onboarding Note

To set our new hire up for success, we envisage that you would need to spend significant chunks of time at our London HQ to onboard with our existing team and learn how we approach end user computing. This could be a few months at the beginning, reducing thereafter to less regular trips. Alternatively, this could be a few weeks at the start and regular periods (2 weeks in every 4) thereafter. XTX would cover all associated costs.
