About the Position

We are looking to hire a talented engineer to help run our internal Windows infrastructure. We are open to applicants with strong experience in areas such as infrastructure, applications, automation, and server or desktop operating systems in Windows environments.

Windows is our primary desktop operating system, and many of our core infrastructure services are provided by Windows servers. Having these systems work correctly is key to meeting our business needs for performance and reliability.

You’ll work to improve, automate and standardise our Windows environment. Ideally this means you have experience scripting/programming in either PowerShell, Python or C#. All of our scripts are centrally managed and stored in an organised repository, where they are reviewed by team members and used by many teams across the firm.

As part of a global team, you will also collaborate with colleagues across the firm—locally and abroad—to develop new ideas, find and resolve issues, plan and execute deployments and document the results.

This position sits within our IT Engineering group, a highly dedicated team of engineers who monitor and manage a Windows environment across a physical/virtual computing landscape that spans three continents. Your analytical thinking and expertise will be invaluable as we support the daily work of our colleagues and keep our systems operating at the highest standard.

About You

While there’s no fixed set of skills required for this role (we can teach you what you need to know), here are some of the things we’re looking for:

Advanced experience with the inner workings of Microsoft Windows 10/11 or Microsoft Windows Server 2016/2019/2022

Experience with using PowerShell (or Python, C#) to automate deployment, configuration and monitoring environments

Strong working knowledge of Active Directory/Kerberos/DNS/Group Policy

Demonstrated ability to troubleshoot Windows operating systems and applications

Experience with hardware monitoring and performance tuning in physical or virtual environments

Ability to solve complex problems in a fast-paced environment

Clear and concise communication skills; the ability to maintain a high degree of customer service for all queries

A flexible, reliable and highly collaborative approach to your work
