Department Overview

On any given day, every moment matters to someone, somewhere. And every moment, Motorola Solutions’ innovations, products and services play essential roles in people’s lives. We help firefighters see around buildings and police officers see around street corners. We keep utility workers connected and visible to each other with real-time voice and data communication across the smart grid. And we provide the situational awareness first responders need when a moment brings catastrophe. We help people be their best in their moments that matter.

Guardian is a call taking & dispatching platform used by emergency service operators across the UK & Europe. We help 999 or 112 operators answer calls from the public and dispatch out nearby responders, enabling the right response when every second counts, and ultimately helping our customers save lives.

As our solution has grown from a small startup to one of the leading offerings for Fire & Police agencies, our customers now trust us to solve more of their problems. You will help us innovate across the Guardian portfolio by working under our senior product leads to refine our core call taking & dispatching offerings, while also getting the chance to carve your own path by leading development for an expansion product.

The Guardian team is distributed across the UK, with hubs in Glasgow, Leicester, and Hemel. We currently have around 150 employees. We have a relaxed but hard working environment where jeans and t-shirts are the norm and good ideas and debate are encouraged. Our daily work is remote and often asynchronous, with workflows managed via Google Chat & collaborative documents in G-Suite. However, you’ll also have the opportunity to join us for frequent in person work & social events like post-work pints, Flight Club darts, or our annual all-hands in Prague.
