Senior Data Engineer

Our mission is to become the global standard for addressing. Street addresses weren’t designed for 2024. 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.

Over the last year, what3words has been used in 193 countries, and our monthly active users continue to grow at an impressive pace. Our tech is used by emergency services, delivery companies, eCommerce businesses, ride-hailing apps and NGOs, and is integrated into the navigation systems of millions of cars around the world.
