Senior Engineer - Front End
Confirmed on the employer's own hiring board on Nov 6, 2026. First seen by Alion on Aug 4, 2026.
Street addresses weren’t designed for 2026. 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
Based in Vietnam out of our centrally located Ho Chi Minh City office, we’re looking for an experienced Front End Engineer who knows code, and enjoys creating engaging experiences that people love to use.

You will have good experience of building sleek user interfaces on top of RESTful web APIs, using React, JavaScript, CSS. You will be able to work independently, self-motivate, collaborate well with others and keep calm under pressure.
