iOS Developer

Mobile Engineer: iOS - Swift

Remote / Hybrid: Somerset-based client – onsite working a day or two a week is preferred

Salary: £55,000 – £75,000

If you are an iOS Engineer looking for a culture-first, mission-driven organisation where your work will have a real-world impact on people’s lives – then this could be the role and company for you.

SR2’s client has a consumer facing platform which interacts with customers via mobile apps. You’ll take ownership of major parts of our clients Swift mobile experience across two apps, working in a small, high-trust team where engineers have genuine input into what gets built and how.

This is a build-and-ship role: balancing reliability and performance improvements with fast, iterative feature delivery.

Overview:

• Build new features and improve existing flows using Swift (ideally SwiftUI where appropriate, or UIKit where needed).
• Integrate and collaborate on API/data contracts with REST services as well as real-time gRPC based services
• Implement payment flows where needed (e.g. Stripe)
• Improve legacy areas and raise engineering standards (architecture, testing, CI/CD)
• Enhance performance, reliability, and offline capabilities
• Collaborate closely with product and operations to ship usable releases quickly

Requirements:

• Strong experience shipping production iOS apps in Swift.
• Solid understanding of mobile architecture patterns (e.g., MVVM, Clean Architecture), dependency management, and maintainable codebases.
• Confident with APIs and data modelling; comfortable collaborating on backend contracts and database structure.
• Practical testing mindset: unit tests (and UI tests where appropriate), with a quality-first approach.
• Ownership mentality: you can lead sizeable features independently and communicate clearly.
• Firebase (Firestore, Auth, Functions, Messaging) and/or event-driven mobile patterns.
• Stripe / payments experience.
• Experience working in early-stage teams where priorities and scope evolve fast.
