REQUIREMENTS:
Bachelor’s degree in Computer Science, Software Engineering, or related field (or equivalent professional experience).
Minimum of 5 years of experience in iOS development with strong exposure to production support and maintenance.
Strong expertise in Swift and deep understanding of the iOS SDK and Apple frameworks (UIKit and/or SwiftUI).
Proven experience handling production incidents, crash investigations, and urgent hotfix deployment.
Strong understanding of iOS application lifecycle, threading, concurrency (GCD / async await), and memory management (ARC).
Experience analyzing crash reports, thread states, memory leaks, and performance bottlenecks.
Experience analyzing application metrics, crash data, and user feedback via App Store Connect.
Experience working with monitoring tools, crash reporting platforms, and analytics dashboards.
Solid understanding of REST API integration, network error handling, and backend communication troubleshooting.
Strong understanding of mobile application security best practices (e.g., secure storage using Keychain, HTTPS enforcement, certificate validation).
Experience managing distribution certificates, provisioning profiles, signing configurations, and release processes to the Apple App Store.
RESPONSIBILITIES:
Handle maintenance activities across multiple iOS projects.
Deliver hotfixes for critical production issues with minimal user impact.
Prioritize and manage incidents based on defined SLA levels (L0, L1, etc.).
Ensure production incident resolution meets agreed MTTR (Mean Time To Recovery) targets.
Provide rapid response for critical incidents, including outside working hours when required.
Perform detailed Root Cause Analysis (RCA), define workarounds, and implement permanent corrective and preventive actions.
Execute preventive initiatives to maintain and improve application stability, crash free rate, memory usage efficiency, and responsiveness.
Analyze crash reports, thread states, and performance diagnostics using Xcode tools and crash reporting platforms.
Conduct continuous application and system monitoring using analytics and Application Performance Monitoring (APM) tools.
Review system performance including CPU usage, memory footprint, rendering performance, and network behavior, and provide structured technical improvement recommendations.
Manage and systematically reduce technical debt through refactoring, modular improvements, and architectural cleanup.
Ensure dependency updates, iOS SDK compatibility, and compliance with Apple platform policies and security standards.
Maintain and improve application performance and rating stability on the Apple App Store.
Manage distribution certificates, provisioning profiles, signing configurations, and App Store deployment processes to ensure uninterrupted service.
Ensure application security compliance with industry best practices (e.g., OWASP Mobile standards, secure storage, HTTPS enforcement, Keychain usage).
