Mobile iOS Engineer

About the Role

• We're looking for a Senior iOS Software Engineer to maintain and evolve a production iOS app at a U.S.-based design marketplace that has reached over 75 million homes worldwide. The app — a consumer contacts and address management tool with deep integration into the ordering experience — is live on the App Store and used daily by real customers.
• You'll take ownership of bug fixes, SDK upgrades, and architectural decisions, including implementing additional sign-in providers. This is a mature codebase that needs someone who can jump in, navigate confidently, and make meaningful contributions from day one.

About You

• You have 5+ years shipping production iOS apps in Swift and you're comfortable owning a codebase you didn't write.
• You're fluent in RxSwift — you can read, modify, and extend an Rx-heavy codebase without introducing subtle subscription bugs.
• You bring strong analytical skills and a pragmatic approach to balancing technical decisions with business needs.
• You communicate clearly in writing, work well in async and remote environments, and articulate complex technical concepts to diverse audiences.
• You take architectural ownership seriously and bring opinions on design patterns backed by production experience.

What You'll Be Doing

• Investigate and fix identified bugs across the production iOS app.
• Upgrade the app to current SDK and dependency versions, resolving conflicts as needed.
• Implement client-side support for additional sign-in methods: Facebook Login, Google Sign-In, and Sign in with Apple — including App Store compliance for SIWA.
• Provide architectural leadership in selecting and applying design patterns within the existing MVVM + Coordinator structure.
• Extend the AuthenticationManager abstraction to support new identity providers.
• Contribute to code reviews and help maintain engineering standards across a collaborative, metrics-driven team.

What We're Looking For

• A pragmatic problem solver who balances technical rigor with shipping velocity.
• Strong ownership mindset — you take full responsibility for the features and fixes you deliver.
• Clear, async-friendly written communication and the ability to work effectively across a distributed team.
• Genuine interest in code quality, maintainability, and leaving codebases better than you found them.

Technical Requirements

Must-Haves

• 5+ years shipping production iOS apps in Swift.
• Strong RxSwift / RxCocoa experience in a production codebase.
• Hands-on experience implementing Sign in with Apple, Google Sign-In, and Facebook Login (or two of three with the ability to pick up the third quickly).
• Solid UIKit + Coordinator pattern experience.
• CocoaPods proficiency, including resolving dependency conflicts during major SDK upgrades.
• Strong Git / GitHub workflow and code review discipline.

Nice-to-Haves

• Familiarity with Okta as an identity provider or OAuth/OIDC token-exchange flows.
• Firebase Crashlytics and Remote Config experience.
• Experience evaluating or executing a CocoaPods to Swift Package Manager migration.
• Camera / Vision framework experience for on-device text recognition.
