Essential skills:

Expert Swift and deep UIKit fundamentals

SwiftUI experience and the appetite to write new work in it

Proven track record of shipping consumer-facing, high-performance, maintainable, efficient code and operating production iOS apps at scale - youve owned features through rollout, monitoring, and incident debugging

Experience in large, modular codebases, in product-focused iOS application development

Fluency in reactive patterns A strong testing culture - unit, snapshot, and component/UI tests as part of everyday work. Experienced at keeping the tests healthy. Experience using the XCTest framework for unit and UI testing

Product-minded pragmatism: experiments, metrics, iteration

Proficiency in profiling and optimising iOS apps

Understanding of design patterns and Object-Oriented Programming

Comfortable using AI tools such as Claude Code

Ability to work cross-functionally with mobile engineers, backend, QA, product managers, and designers. Ability to document and communicate technical approaches clearly. Strong collaboration and communication skills

Comfortable working with monetisation and payment flows (credits, subscriptions, in-app purchases)

Solid computer science foundations: algorithms, data structures, concurrency, threading

Nice to have

Computer Science/Tech related degrees

Experience with CI/CD pipelines and deployment practices (TeamCity or similar)

Swift 6 / strict-concurrency experience

Protobuf/gRPC or other schema-driven API tooling

Unidirectional/Redux-style architecture experience (TCA or similar)

Tuist, Bazel, or other modular build systems at scale

Experience shipping multiple app targets from one codebase





Familiarity with A/B testing frameworks and feature flagging for gradual rollouts

Knowledge of socket-based networking and binary protocols

Familiarity with analytics, remote reporting, and performance metrics

Youll ship features for millions of users from a modular Swift monorepo that powers iOS App apps in the portfolio. You will own and drive product & technical projects from idea through to delivery and post-production monitoring.

The iOS App app is a mature, entirely-Swift codebase: UIKit-based, MVVM with coordinators and generated dependency injection, our in-house BPObservables reactive layer, and a protobuf-based API talking to iOS Apps high-scale backend (with some components on gRPC stack). Chat is built on Chatto, our open-source messaging framework. Youll both build the iOS App product and shape what the modern codebase becomes.

Architecture matters here. The platforms direction is set: new modules are written to the modern standard, so youll maintain and evolve a production UIKit app while writing new work on the modern stack and helping carry iOS App there.

What youll do

Build and ship user-facing features end-to-end across iOS Apps feature modules

Partner closely and collaborate cross-functionally with Backend and Android, QA, Product & Design teams





Work with a protobuf/gRPC API layer shared with our backend teams - you will own the client side of the contract

Write recent modules to the modern platform standard (SwiftUI) while keeping the existing UIKit/MVVM codebase healthy

Test at every level: XCTest unit tests, snapshot tests, component/UI testing; extend coverage where its thin

Verify your changes end-to-end on supported devices using our test tooling to ensure high-quality standard and delightful member experience for shipped changes

Run A/B experiments, measure impact, and iterate with product and design

Adopt AI tools to accelerate ideation, prototyping, and iteration on new features, enabling faster experimentation with production-ready code

Participate in code reviews and mentor

Maintain and evolve the iOS App app (occasionally support other apps from iOS App Inc. portfolio) and contribute to the evolution of iOS App s codebase

Contribute to incident management - ensuring 100% of incidents are handled, postmortems written, and actions taken

Build and maintain monetisation logic like credits-based flows, subscription features

Our stack: Swift (essentially 100% of app code) UIKit with SwiftUI in newer modules MVVM + Coordinators, code-generated DI BPObservables (in-house reactive) with some Combine MAPI protobuf/gRPC networking Cosmos design system Tuist monorepo XCTest + SnapshotTesting + demo-app component tests
