London United Kingdom


Who we are:
Our mission is to become the global standard for addressing. Street addresses weren’t designed for 2022. 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.

Who we’re looking for:
We’re looking for a Full Stack Engineer to join the team who enjoys integrating with a variety of services and applications to build integrations and solve client problems. This role is to help partners create great products using the what3words APIs and components.

At what3words, we’re proud of our tech stack. We have built a massively scalable, microservices-based architecture, based around Kubernetes on AWS. You’ll be exposed to technologies such as Docker, React, Node, EKS, Consul, AWS, Alexa, Flux, CircleCI, ArcGIS and other platforms.

This a great opportunity to join a collaborative and ambitious team, at one of the most exciting times in this company’s life.

  • Create plugins, APIs, components, libraries and SDKs for use in partner products
  • Provide documentation and direct support to partner integrations
  • Help build out our partner strategies

  • RESTful API design and implementation, working on B2B2C products and supporting external developers
  • Keen to work full stack and cross-functionally across teams
  • Ability to produce high quality code as part of a complete system, delivering complete solutions with automated tests, and documenting code + systems for handover
  • Deliver and support working software all the way to both clients and end users and support after launch

Extra credit if you:
  • Java / Python / C# experience a bonus

The role is based in our London HQ (at Great Western Studios - ///filled.count.soap). While you can work from the office five days a week if preferred, our Engineering team can choose to work up to three days a week from home. We also offer a remote-work allowance; for up to six weeks a year, you can work from anywhere in the world (as long as you’ve got great WiFi and are happy to work on the HQ timezone).
