Job description

At Forge, we bring together a global portfolio of market-leading businesses and specialist teams, connected by the technology and systems that help them do their best work. We’re collaborative, ambitious, and always looking for smarter ways to build, improve and grow.

We’re looking for a Senior Systems Administrator to join our UK team, based in Shepherd’s Bush, London. We’re looking for someone experienced, proactive, and excited about taking ownership of a world‑class tech environment and helping shape how it grows.

This is a role that requires a critical onsite presence within one of our UK businesses, This is Beyond, and complements our expert US‑based Forge IT team. You’ll be based at the This is Beyond office but report into an IT leader at Forge, working closely across our systems and teams. It’s a hybrid, cross‑functional role with real ownership across our UK and South Africa IT environment, especially suited to someone who loves improving systems, automating, and connecting the dots.

Who You Are

To be successful in this role you'll be curious, calm under pressure, and love helping people solve tech problems from "my Wi‑Fi won’t connect" to "can you help me automate this system‑wide rollout." You’ll be great at managing your own time, jumping between Mac and Windows, and be looking for more than just reactive ticketing, you'll want to contribute to big‑picture improvements and proactive support.

You will need to be comfortable taking ownership and working independently in an onsite environment, while knowing when to ask questions and loop in your wider team. You’ll be confident making recommendations, identifying improvements and bringing your own experience and ideas to the wider Forge IT team. You get excited by new tools, big transitions, and smart solutions, and still want to keep learning as the business grows.

What You’ll Do

• Set up and support employee workstations and infrastructure in a cross‑functional and hybrid office environment
• Deploy and support company laptops (both Windows and Mac OS)
• Administer, maintain, and continuously improve Office365, Entra ID and Azure environments for our UK and EU‑based users
• Deploy security patches, application patches, configuration changes, and registry updates using RMM/MDM tools to endpoints
• Take ownership of endpoint security, patching and appropriate security controls to help protect the organisation’s data and infrastructure
• Participate in the change management process and support systems, infrastructure, migration and rollout projects
• Carry out daily administrative tasks, reporting, and communication with relevant departments
• Maintain antivirus software and ensure coverage across networks
• Own and resolve service desk tickets end‑to‑end with efficiency and clarity, escalating to the wider Forge IT team where appropriate
• Identify opportunities to automate repetitive administrative tasks and processes (PowerShell a plus).
• Lead or play important role in IT systems integration in all current and future acquisition

What You’ll Need

• Proven experience in a Senior Systems Administrator, Senior Systems Engineer or similar role, with the confidence to independently own an IT environment
• Experience supporting both Windows and Mac OS
• Confidence working with cloud platforms (Azure or AWS)
• Strong working knowledge of Office365, Active Directory and Entra ID
• Strong working knowledge of Google Workspace.
• Hands‑on knowledge of patch management, antivirus, and endpoint detection
• Experience with MDM/RMM tools and virtualisation
• Ability to work independently, take ownership of technical issues and manage service tickets end‑to‑end
• Bonus points for PowerShell scripting, network knowledge and experience working with third‑party IT suppliers or vendors
• Experience supporting systems through acquisitions, mergers or business integrations
• Strong understanding of security stack (Crowdstrike, Wazuh, Defender, etc)

How This Role Is Structured

• You’ll be based onsite in our Shepherd’s Bush office four days a week (Monday to Thursday), with Friday working from home. You’ll need to be flexible to attend the Shepherd’s Bush office or another London location on a Friday if IT or business needs require onsite support.
• You’ll report directly into a US‑based IT manager within Forge’s wider team
• You’ll have daily check‑ins with the broader Forge IT team and full support behind you
• You will also take ownership of day‑to‑day IT across our UK and South Africa entities, working closely with the wider Forge IT team to keep systems, infrastructure, security and support running smoothly.

Why Us?

As part of Forge, you’ll have access to advanced tools, career pathways, smart colleagues, and a wider global team to learn from and collaborate with.

We believe in thoughtful work and keep standards high - from the way we launch an event to how we reset a router. You’ll get the best of both worlds: a close‑knit team culture onsite, and access to a global IT operation that’s growing, learning, and building better systems every day.

Benefits:

Enjoy a range of benefits, including: Pension Scheme, Hybrid working arrangement, Private Medical Insurance, Life Insurance, 30 days annual leave per year.

Position Type:

Permanent, 5 day working week. 4 days based in our Shepherd’s Bush office, with Friday working from home. Flexibility to attend the office on Fridays will be required if IT or business needs arise.
