Lead Front End Developer at what3words
London, GB

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.

We’re looking for a Lead Front End engineer who has built and delivered innovative products and features and who enjoys creating engaging experiences that people love to use. 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 ReactJS, Docker, Redis, AWS Lambdas, Prometheus, Grafana, Python, Athena, BigQuery, Java, Scala, C++, and Swift.

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


    Deep expertise in Javascript (ES6), TypeScript, React, HTML, CSS
    Excellent communication skills in verbal and written English.
    A passion for software engineering and continuous learning.
    Strong track record of building responsive sites for desktop, tablet and mobile.
    Experience as a technical lead in cross-functional teams, leading architecture decisions and working with other product and engineering leaders
    A passion for helping people grow and seeing them successfully navigate complex challenges
    Ability to create a supportive and inclusive culture, listening to others, and finding the opportunities for your team to grow
