We're looking for an iOS Engineer to join our Software team and help design, build, and evolve the native iOS apps that players and coaches rely on, on the training pitch, on match day, and everywhere in between.

This is a product-focused role where you'll take ownership of features end-to-end, from Bluetooth communication with our wearable GPS devices and data sync through to polished, user-facing experiences in Swift and SwiftUI. You'll work closely with Product Owners, designers, and our Android and backend engineers, and you'll have real scope to bring AI-powered features to life, both on-device and through our AWS generative AI stack.

If you're enthusiastic, curious, love solving problems creatively, and follow the sport as closely as you follow the tech, this role is for you.

• Designing, building, testing, and supporting native iOS applications in Swift, using SwiftUI (and UIKit where it makes sense)
• Building and integrating AI-powered features, consuming services built on AWS Bedrock, and exploring on-device capabilities such as Core ML and Apple's Foundation Models framework
• Integrating with our serverless backend APIs and designing for offline-first use, with solid caching and sync so the app works on the side of a pitch with patchy signal
• Owning and improving the release pipeline, CI/CD, automated builds, TestFlight, and App Store submissions
• Writing meaningful unit and UI tests (XCTest / Swift Testing) and taking responsibility for the reliability, performance, and battery impact of what you ship
• Collaborating with Product Owners, designers, and our Android team to turn ideas into working features that provide meaningful insight to players and coaches, consistently across platforms
• Bringing creative, outside-the-box thinking to problems
• Working within an Agile environment, actively taking part in planning, reviews, and continuous delivery

• Have experience building and shipping native iOS apps in Swift, and are comfortable with SwiftUI, Swift Concurrency (async/await), and modern app architecture
• Understand the iOS platform well, app lifecycle, background execution, permissions, privacy requirements, and App Store review guidelines
• Are comfortable consuming REST APIs and working alongside backend engineers; exposure to AWS (S3, serverless, Bedrock) is a bonus
• Have some familiarity with Android or Kotlin; not essential, but it helps when working closely with our Android team
• Have used AI tools as part of your own development workflow, and are curious about applying AI within a product
• Love to learn, AI is moving fast, and you actively keep on top of it: trying new models and tools, following releases, experimenting in your own time, and bringing what you find back to the team
• Are enthusiastic to learn, keen to take ownership as you grow, and happy to get stuck in
• Enjoy solving problems creatively and thinking outside the box rather than just following a spec
• Are genuinely into sport, whether that's playing fantasy football, deep in Football Manager or FIFA/EA FC, following coaching and tactics, or just a lifelong fan; you'll understand our users because you are one
• Communicate clearly and enjoy collaborating across product, design, and engineering
• Can reason through problems and articulate your thinking clearly, and collaborate with external teams like Support and Product to get to the bottom of issues fast, often working from limited information (a crash report, a device model, a vague description) to debug and unblock without putting extra strain on other departments
• Can quickly tell the difference between a genuine support/technical issue and user error, and know how to investigate and communicate that clearly
• Have personal or side projects you're proud of, an app on the App Store, something you built for yourself or your team, an open-source contribution, or anything that shows what you've learned and built outside of work; we'd love to hear about it and see it

• A product-focused role building AI-powered mobile apps used by players at scale
• Ownership of meaningful features from concept through to delivery
• Hands-on experience with connected wearable hardware, the latest Apple frameworks, and cutting-edge AWS AI services
• A culture that values curiosity, autonomy, learning, and a genuine love of sport
• The chance to see your work in players' pockets every day
