In a nutshell.
As iOS Engineer at Check you will be responsible for growing the iOS customer application of Check, downloaded by more than a million people and being used by thousands of users every day.
The role.
As iOS Engineer at Check you'll be part of the mobile team that works on the customer application. Our app is native in Swift and uses the latest frameworks and best practices.
Together with the rest of the Mobile team, you'll focus on growing the app with new features and other user-centric improvements. You'll be working side-by-side with a senior iOS engineer. You'll also spend time on maintaining the customer app and improving its stability, performance and accessibility.
Our tech stack.
The iOS application is built 100% with Swift, with a mix of SwiftUI and UIKit. We use REST APIs to connect to our backend. The CI/CD pipelines run using Bitrise.
Android is built natively with Kotlin. Next to the customer application, we have two internally facing applications. One mobile React Native application and one web-based, built in Typescript and Next.JS.
Our backend stack is heavily based around Python, because our main API is written in that language, as well as several microservices. For updating our fleet in real-time, we use a microservice which is written in Rust. This is all hosted and managed in-house, by running two Kubernetes clusters and Helm as our package manager.
