Senior Frontend Engineer


At our vision is to make effective human support accessible to vulnerable people everywhere.

We're creating a product that allows social impact organisations to have private, personal and guided conversations on chat to improve lives at scale. We work with small and large social enterprises, non-profits, and governments who are all trying to change the world for the better, using our product. We have a strong focus on health.

Here are a few examples of how some of our customers have used Turn to make an impact:

  • In response to the COVID-19 pandemic, the World Health Organisation delivered a combined total of 60 million messages to over 15 million people, providing them with instant and easy access to the most accurate and up-to-date information shared by their governments and health organisations.
  • The South African National Department of Health improved health outcomes for 450,000 pregnant women through WhatsApp, by providing a 24/7 support line and a self-service knowledge repository that guides women through pregnancy and the first 2 years of a child’s life.
  • Guidepost is on a mission to make personalised diabetes coaching available to as many people as possible, providing this service through WhatsApp and helping people with diabetes live a healthier and longer life.
  • The United Nations has empowered people to make climate action an integral part of their daily life and be part of the solution to the climate crisis through their “UN Climate Action” WhatsApp service.
  • Rising Academy, who is on a mission to create the most powerful teaching and learning tools for the people that need them most, has improved maths educational outcomes for children in Ghana through delivering quizzes and providing tutoring through WhatsApp.

Our product has come a long way in a short space of time, with a small but brilliant team. The team is now growing and we’re looking for a Senior Frontend Engineer to help us shape and build the product to grow and deliver on our behaviour change goals. In the past year, our team has loved seeing their work immediately being used in high-impact services.

This is an exciting opportunity to join a funded startup in its founding years and experience and shape the growth of a product first hand. We are a global team working remotely and asynchronously. If you’re highly skilled with innovative, unique development ideas, and a creative, troubleshooting mindset, we’d like to hear from you.
