On-site IT Support Engineer

About Zenzero

Zenzero is one of the UK's fastest-growing technology companies. Named a Top 8 Technology Company at the British Business Awards 2026, recognised by Deloitte as a Best Managed Company, and featured in the Sunday Times Hundred (an annual ranking of the UK's fastest-growing private companies) in both 2025 and 2026, we hold Microsoft Solutions Partner status across all six designations, putting us in the top tier of UK Microsoft partners. The accolades reflect something real: a business that is scaling fast, executing well, and building something that lasts.

We're on a mission to make technology genuinely work for mid-market businesses, covering managed IT, cyber security, cloud, and AI solutions that actually move the needle. The demand is growing, and so are we.

We're also a certified B Corp and Scale Up Award winner. That combination matters to us: high growth and high standards aren't in conflict here. Fast growth, high standards, real impact. If that sounds like your kind of place, keep reading.

You'll be working with a range of customers across London from a variety of industries such as finance, marketing, creative and healthcare.

You'll tackle everything our Service Desk can't resolve remotely, working to defined SLAs while playing a key role in deployments and installations alongside our Project teams as well as building relationships with our customers and their teams. We're looking for motivated IT professionals who enjoy the variety that an on-site role brings and have a passion for great customer service.Â
