Fully on-site in Central London

You're the person friends call when tech breaks - and you love getting hands-on with servers, networks and Windows. How about doing that in a small, growing tech team where you can see the impact of what you do every day, and steadily grow your responsibilities as you develop?

This is a rare opportunity to join a highly-automated, data-driven technology business in Central London, working in a small, friendly IT team that underpins a sophisticated trading and analytics environment. They're open to strong juniors through to solid mid-level Systems Administrators, with a salary to match experience.

The Role

• Monitor and maintain in-house software applications, ensuring high availability and rapid issue resolution for a 24/7 trading operation.
• Manage the Microsoft Windows "universe" - administering Active Directory, Group Policy and user access, and keeping systems well-organised and secure.
• Work across networking (primarily Juniper), virtualisation (Hyper-V) and scripting (e.g. PowerShell) to automate, optimise and improve day-to-day operations.
• Take on more responsibility over time as you demonstrate reliability, ownership and the ability to grasp wider concepts and new technologies.

You'll be in the office full-time, working to support researchers and software developers who rely on a robust, well-run environment to do their best work.
