Senior iOS Engineer

Location: Noida, India

Department: Technology

Experience: 5+ Years

• Built and shipped at least one iOS app with 50k+ active users — you know what production scale feels like
• Owned architecture decisions — not just followed patterns someone else set, but chosen between MVVM, VIPER, Clean Architecture and justified why
• Gone deep on Swift — you can explain memory management, value vs reference types, concurrency with async/await and actors without hesitation
• Designed systems on a whiteboard — you can architect an offline-first app, a video player module, or a real-time feed from scratch
• Mentored at least one junior or mid-level iOS developer
• Debugged hard problems — memory leaks, race conditions, frame drops — and have stories to tell about them

• Architecture and technical direction of the iOS application
• Video playback experience — buffering, adaptive bitrate, DRM, PiP
• Performance benchmarking and optimization of the app
• Code review standards and engineering best practices for the iOS team
• Collaboration with product and backend on feature design, not just implementation

• Swift — deep understanding, not just syntax familiarity. Concurrency, memory management, protocol-oriented design
• Architecture patterns — MVVM, VIPER, or Clean Architecture. You know the components, the trade-offs, and when to use what
• UIKit and SwiftUI — can work in both, knows when each is appropriate
• Video technologies — AVFoundation, HLS, DRM (FairPlay), adaptive streaming is a strong plus and the space you'll grow deepest in
• System design — can design a video caching layer, a modular app architecture, or an offline sync system

• Developers who have followed patterns without understanding them
• Ticket-takers who need detailed specs to execute
• Someone who hasn't shipped to the App Store in a real production environment
