Engineering Leadership & Delivery

• Lead iOS‑focused engineering streams across active projects, from discovery to delivery.
• Collaborate with designers, backend developers, and product managers to align implementation plans and integration strategies.
• Review pull requests and mentor team members on iOS best practices, code quality, and platform conventions.
• Ensure code is testable and aligned with CI/CD pipelines (e.g., GitHub Actions, Bitrise, CircleCI, Fastlane).

Cross‑Functional Collaboration

• Contribute to API design and backend integration strategy, advocating for mobile‑friendly contracts.
• Help define and maintain coding standards, tooling, and documentation for mobile engineering.
• Participate in release planning, quality reviews, and issue resolution with project stakeholders.
• Work within agile processes to meet delivery timelines while maintaining quality and stability.
• Coordinate with teammates across time zones to ensure consistent delivery and high code quality.
• Share architecture guidance and technical artifacts across distributed teams and projects.

Platform & Process Excellence

• Evaluate and integrate emerging iOS libraries, UI frameworks, and automation tools.
• Ensure apps meet Apple App Store submission standards and accessibility compliance (e.g., WCAG, VoiceOver, Dynamic Type).
• Support crash analytics, user feedback loops, and observability in production (e.g., Crashlytics, Sentry, analytics SDKs).
• Drive continuous improvement in mobile development practices and team performance.

• 5+ years of professional iOS development experience, including 2+ years in senior/lead roles.
• Expertise in Swift, SwiftUI (and/or UIKit), MVVM, and Swift Concurrency (async/await; familiarity with Combine a plus).
• Strong knowledge of networking and data layers: URLSession/Alamofire, REST/JSON (GraphQL a plus), Core Data (or Realm/SQLite).
• Experience with modular multi‑module architectures and scalable code organization.
• Proven testing practices: XCTest, XCUITest, snapshot testing, dependency injection for testability.
• Familiarity with package/build and release tooling: Swift Package Manager, CocoaPods, Fastlane, code signing, TestFlight, App Store Connect.
• Published apps on the App Store.
• Experience with Git‑based workflows and CI/CD integration (GitHub Actions, Bitrise, CircleCI).
• Understanding of the full mobile development lifecycle, from design through deployment and post‑release iteration.

• Familiarity with SwiftData and modern persistence patterns.
• Experience with widgets, Live Activities, App Clips, and on‑device ML (CoreML/Vision).
• Exposure to cross‑platform or shared‑code strategies (e.g., Kotlin MultiplatformMobile, React Native, Flutter) and/or basic Android fluency.
• Contributions to open source or an active technical blog/GitHub profile.
• Background in travel, hospitality, or IoT‑enabled mobile apps.
• Accountability – owns the delivery of iOS features with quality, reliability, and precision.
• Adaptability – operates effectively in fast‑paced client environments and shifting priorities.
• Collaboration – builds strong working relationships across teams and time zones.
