Job description

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.

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.
