Responsibilities

• Keep our app updated with new iOS versions, features, and devices.

Tech Stack

Our iOS codebase is modern, clean, and well-maintained. We use the latest Apple frameworks and best practices, with a strong focus on code quality, testing, and automation. 

The app is built natively in Swift and uses SwiftUI and UIKit. Deep experience with all three is required. We also use Swift Concurrency, Combine, CoreData, WatchKit, HealthKit, XCTest, etc. The backend uses Firebase. Experience with these additional technologies is a plus, but not required if you’re a fast learner.

Team

You’ll work closely with our Android developer to keep both apps consistent so users get the same features, logic, and algorithms on both platforms. You’ll also work with our product manager and designer to understand user needs and advise on technical feasibility. You’ll work with QA and support to investigate and fix bugs. We communicate mostly in writing and minimize meetings. You’ll have plenty of time to focus on coding and building a great app.

How to apply

Our goal is to find the best iOS developer with the right skills who fits well with our team. We designed our hiring process to be fair, efficient, and respectful of your time.

We’ll start with a short online test (~20 min). This saves us both time, so interviews are only with candidates who have the required skills. If you pass, you’ll move on to a more in-depth coding test (~60 min). Successful candidates will then be invited to interviews, usually about three, each lasting between 30 and 90 minutes. We’re organized so the process will move quickly.

We’re looking for someone who can start as soon as possible.
