Senior iOS Engineer (Core & Health)

Responsibilities

• Lead the design and implementation of core iOS platform capabilities (app architecture, navigation patterns, shared UI components, networking, persistence, and feature flagging)
• Drive technical planning for initiatives, including scoping and sequencing work, identifying dependencies and risks, and communicating tradeoffs and timelines to stakeholders
• Deliver high-quality, member-facing iOS features in Swift, collaborating with cross-functional partners to ensure requirements are met and outcomes are measurable
• Improve app reliability, performance, and maintainability through testing, observability, crash and performance monitoring, and disciplined release practices
• Establish and evolve shared engineering standards through code reviews, documentation, and architectural discussions, influencing patterns used across iOS development
• Mentor and support other engineers through pairing, feedback, and knowledge sharing, helping grow individual capability and the overall health of the codebase

Qualifications

• Significant experience building, testing, debugging, and shipping native iOS applications in production environments
• Strong proficiency with Swift and iOS frameworks (SwiftUI, UIKit, XCTest) and experience with modern architecture patterns (MVVM)
• Experience leading technical planning and delivery for ambiguous, cross-cutting iOS initiatives (modularization, large refactors, performance programs, or reliability initiatives)
• Strong foundation in iOS performance and reliability fundamentals (memory management, profiling, and concurrency with Swift Concurrency and/or GCD)
• Experience integrating mobile apps with backend services and APIs (RESTful APIs, authentication flows, and resilient networking)
• Familiarity with common iOS tooling and workflows (Xcode, Git, CI, Fastlane, Swift Package Manager, CocoaPods)
• Demonstrated ability to collaborate effectively across functions (Product, Design, QA, Data, and Backend Engineering) and communicate clearly with technical and non-technical audiences

Nice-to-Haves

• Experience building shared mobile foundations across platforms (collaborating closely with Android on patterns and releases)
• Contributing to backend services and APIs (Java)
