Field Operations Engineer - South Croydon

The opportunity:

We are seeking a proactive engineer to be the face of Wifinity for our clients across a patch stretching from South Croydon towards the South Coast, supporting customer sites across the wider South East region, over approximately 50 miles of territory.

About us:

Wifinity was founded in 2007 to solve a problem - our armed forces were struggling with reliable connectivity. While living in barracks, often in remote locations, ordering a landline and booking in an engineer just wasn’t an option.

And that problem isn’t exclusive to the military, either. Students living in University accommodation, families visiting holiday resorts, or living in shared accommodation and retirement communities.

Conventional home broadband doesn’t always work for them.

Wifinity is different. We offer the same benefits as traditional broadband, such as super‑fast speeds, WiFi, and secure and private networks, but none of the downsides. We even offer Pay As You Go and flexible contracts, so customers only pay for what they need without hefty penalties or long contract terms.
