ROLE OVERVIEW
We are looking for a Senior Software Engineer – iOS to build and evolve mission-critical iPhone, iPad, and Apple Watch experiences with a strong emphasis on real-time location and activity tracking. You will lead design and implementation of accurate, reliable tracking (including background execution, offline behavior, and intermittent connectivity), deliver polished user experiences, and partner closely with backend and product teams to ship secure, performant features at scale.

RESPONSIBILITIES

• Design, develop, and maintain high-performance iOS applications with a strong focus on reliability, scalability, and user safety
• Lead end-to-end implementation of real-time location tracking (Core Location, GPS accuracy tuning, geofencing, routing), including efficient background updates, graceful degradation under OS constraints, and robust edge-case handling
• Implement activity tracking and motion-aware experiences (e.g., walking/driving detection) using Core Motion / Activity APIs and (where applicable) HealthKit/Workout sessions on Apple Watch
• Optimize battery, CPU, memory, and network usage for always-on/near real-time experiences; instrument and monitor performance in the field
• Build intuitive, high-quality UI/UX aligned with Apple Human Interface Guidelines and modern iOS design practices
• Write clean, testable code; create unit/integration tests and improve engineering quality through reviews and standards
• Integrate with backend services (REST, realtime messaging where needed), support offline sync, and ensure data integrity and resiliency
• Collaborate with product, design, and QA to deliver features on time; mentor engineers and contribute to technical direction
• Stay current with emerging iOS technologies and AI-assisted development tooling to improve productivity and user experience

QUALIFICATIONS

• Bachelors in IT/Computer Science/Software Engineering
• 6+ years of hands-on iOS development experience (iPhone, iPad; Apple Watch experience preferred)
• Expertise with Swift and iOS fundamentals (concurrency/multithreading, memory management, performance profiling)
• Strong knowledge of Apple Human Interface Guidelines and building polished, accessible experiences
• Deep understanding of iOS architectural patterns (MVVM, MVP, VIPER) and writing maintainable, testable code
• Hands-on experience with UIKit/SwiftUI, Auto Layout, persistence (Core Data/ORM), JSON, and modern dependency management
• Deep expertise in Core Location: GPS accuracy tuning, significant-change/region monitoring, background execution constraints, OS throttling, permissions, and intermittent connectivity handling
• Experience with activity/motion tracking using Core Motion (and optionally HealthKit/WorkoutKit/watchOS background sessions)
• Strong experience with REST APIs (URLSession), authentication flows, and push notifications (APNs)
• Experience with mapping frameworks such as MapKit (and/or Google Maps SDK for iOS)
• Solid experience with debugging, automated testing (unit/integration), CI/CD, and App Store release processes
• Strong grasp of privacy and security considerations for location data (consent UX, data minimization, and secure transport/storage)
• Strong problem-solving skills and ability to manage multiple priorities in a fast-paced environment
