Senior Systems Administrator

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.

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.
