Senior Front End Developer Job Description | what3words

About what3words

Street addresses weren’t designed for 2020. They aren’t accurate enough to specify building entrances, and they don’t exist for parks, rural areas and many parts of the world. This makes it hard to find places and causes problems and inefficiencies on a global scale.

That’s why we created what3words. We divided the world into 3m squares and gave each square a unique combination of three words. It’s the easiest way to find and share precise locations.

Last year, what3words was used in 193 countries, and our monthly active users increased from 100,000 to over a million. Our tech is used by emergency services, delivery companies, ride-hailing apps and NGOs, and is integrated into the navigation systems of Mercedes-Benz cars.

what3words is available in over 40 languages

We’re used by emergency services across the UK and internationally

And we were also iOS App Store App of the Day in 143 countries
