Senior React Native Engineer (Superapp)

We’re looking for a Senior React Native Engineer to join our cross-functional team and build new product experiences in our established Zable App, used by over 500,000 customers on iOS and Android. Over the next year, we have big plans for our app, including new products and bringing Zable to a new audience.

We are scaling our dev team to match our ambition, and we’re looking for talented people to help us experiment and succeed in these new areas. In addition to feature work, we also focus heavily on improving performance, reducing tech debt, and improving scalability.

Our ideal engineer is detail-focused, resourceful, and keen to understand the bigger picture outside of their product team. They contribute to wider engineering and business initiatives that help us scale our UK and US-based products as we continue to grow.
