About the role

Aplyr's Quick Take

This role is for a Senior React Native Engineer who will lead the development of a new mobile app for investment management. You'll be hands-on, defining architecture and patterns while collaborating with clients and other engineers. It's an individual contributor position with a focus on mobile engineering and consulting.

Good fit

Ideal candidates have extensive experience in React Native and mobile app development, along with a strong ability to work independently. A background in finance or consulting could be beneficial, and a collaborative working style is essential.

Worth noting

You’ll be the first mobile engineer on this project, which means a lot of responsibility and influence over the app’s direction. The role is hybrid, requiring only one day a week in the office, which may appeal to those seeking flexibility.

The Role
