Role: iOS Engineer (Swift Developer)

Client is supporting a global technology company operating in the human performance and health data space. Their platform enables organisations to collect, analyse, and act on complex human‑centric data to drive performance, wellbeing, and decision‑making.

The successful candidate will join the Mobile Platform Development team to work on a mobile application focused on human performance and data capture. This role involves contributing to the enhancement of an existing application as well as delivering new features across modules such as messaging, scheduling, data capture, and reporting. The app incorporates a shared data/network layer via Kotlin Multiplatform.

This is a mid‑level role. Candidates should be hands‑on contributors rather than primarily team leads or architects.

About The Project

The engineer will join an established mobile team working across iOS and Android platforms, reporting to an Engineering Manager.

• Current State: A mix of enhancing existing app features and greenfield development for new functionality.
• Architecture: Strong focus on modern iOS architecture using MVVM and Coordinator‑based patterns for scalable feature and navigation management.
• Tech Stack: Modern iOS development including Swift, SwiftUI, UIKit, modern concurrency, and Core Data. Strong preference for candidates using modern iOS practices (SwiftUI, async/await, structured concurrency), rather than legacy‑only UIKit patterns.

Responsibilities

• Build and maintain iOS application features within a production mobile app.
• Develop intuitive user interfaces to simplify complex data input and visualization.
• Collaborate with Product, Design, and domain specialists to deliver new features.
• Write well‑tested and maintainable code following established team architecture and patterns.
• Participate in the product lifecycle, including development, testing, and release.
• Contribute ideas for improving team processes and tooling.
• Candidates should be comfortable owning and delivering small‑to‑medium features end‑to‑end within a sprint, with support from senior engineers.

Requirements

Technical Experience

• Swift / SwiftUI / UIKit: 3+ years
• REST APIs: 1–2+ years (GraphQL beneficial but not required)
• CI/CD: 1+ year
• Testing Frameworks: 2+ years (XCTest or similar)
• Dependency Management: Experience with Swift Package Manager (SPM)
• Architecture: Good understanding of common iOS architecture patterns such as MVVM and Coordinator‑based navigation, including how they are applied in production apps.
• Experience working with or integrating into shared cross‑platform layers (e.g. Kotlin Multiplatform) is highly beneficial. Candidates should be comfortable consuming externally defined data/network layers.
• Concurrency: Familiarity with modern Swift concurrency (e.g. async/await)
• Development Practices: Experience with version control, app deployment, and Agile workflows.
• Software Fundamentals: Understanding of object‑oriented principles and design patterns.
• Market Experience: Experience working on product‑focused applications (SaaS or similar), collaborating closely with Product, Design, and QA in iterative delivery environments.
• Hands‑on experience writing unit tests (XCTest or similar) as part of regular development workflow.

Soft Skills & Business Experience

• Technical English: Fluent (Level 5).
• Methodology: Minimum 2 years of experience with SCRUM.
• Stakeholder Interaction: Experience working with Product and QA teams.
• Key Behaviours: Strong collaboration skills, empathy for end‑users, and a pragmatic, iterative approach to problem‑solving.

Bonus Skills

• Experience with cloud services (serverless, notifications, storage)
• Good UI/UX sensibility
• Experience in Kotlin
• Background working in feature‑driven product teams

What Good Looks Like

• Strong candidates will demonstrate clear ownership of features within mobile applications.
• Experience working within structured architectures (MVVM + navigation patterns).
• Ability to articulate technical decisions and trade‑offs.
• Contributions to production applications with real users.

Hardware & Compliance

• Hardware: Candidates should ideally have an Apple MacBook (Minimum specs: 14" Pro M2+ 32GB RAM 1TB Storage) for Jamf endpoint management.
• Compliance: Signed confidentiality agreement and participation in detailed security training are mandatory.
