Mobile Engineer - IOS

About this role

OVERVIEW: This role exists to build and maintain the iOS app that a large share of Gymshark customers shop through, at a standard that holds under peak load. You will turn refined product work into features that are shipped, tested and observable, and improves the quality of the code you touch. WHAT YOU'LL BE DOING: CRAFT Writes production Swift confidently. Most new work is SwiftUI; the app still contains UIKit that is being migrated, so both are relevant.

Works effectively in a modular codebase. Understands why a type belongs in one module rather than another, and adds features without crossing module boundaries. Applies Clean Architecture and MVVM as standard, can explain the separation of concerns, and identifies where a pull request breaks it. Writes unit tests as part of the work rather than afterwards, and is comfortable building test doubles. Some of the team work test-first, and we want to increase that.

Understands Swift concurrency sufficiently to avoid data races, and raises it when a problem exceeds their experience. Diagnoses production issues from crash reporting and analytics, and identifies the root cause independently. Treats performance, accessibility and app size as part of completing a piece of work. Understands the path their code takes after merge: CI, review, distribution and App Store submission, and the common failure points at each stage.

Uses a branching strategy consistently and writes pull requests that are straightforward to review. Raises design specifications that conflict with the Human Interface Guidelines rather than implementing them unchanged. Considers security and dependency risk routinely, and can assess whether a third-party SDK should be added DELIVERY Contributes actively to Agile ceremonies, and raises when one is no longer useful. Helps Product Owners refine stories into buildable work, and raises when a story is not ready.

Breaks work into increments that each deliver value, rather than a sequence that only delivers at the end. Demonstrates their own work to non-technical stakeholders and explains its value in plain language. Raises problems early, while they are still inexpensive to fix. CULTURE Uses their 10% time and shares what comes out of it. Cross-skills beyond iOS sufficiently to work with adjacent teams. <li data-leveltext="" data-font="Wingdings" data-listid="21" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Wingdings",
