Job summary

Aecor Digital Limited is seeking a Senior Mobile Developer who has deep experience in native iOS and Android, plus cross‑platform work, to ship production‑quality releases.

The role covers feature development, live app support, secure coding practices per OWASP MASVS, release engineering, and strong debugging across real devices.

Candidates should demonstrate ownership, performance profiling, and the ability to work across both native and cross‑platform codebases.

Qualifications

• 5+ years of professional mobile development experience with production apps released on App Store, Google Play, or both.
• Experience across cross-platform and native: Flutter, React Native, or both.
• Deep expertise in native Android (Kotlin/Java) and/or native iOS (Swift/Obj-C) with ability to work on the other platform.
• Strong fundamentals: data structures, design patterns, concurrency and threading, memory management, MVVM/MVI/Clean architecture.
• API integration: REST/GraphQL, authentication flows, offline storage, security, and release engineering.

Responsibilities

• Deliver features end to end from story through implementation, testing, and release readiness.
• Own issues end to end: investigate, reproduce on real devices, root-cause, fix, and verify with no regressions.
• Work across cross-platform and native codebases to keep behaviour and parity consistent.
• Write secure, production-quality code aligned with OWASP MASVS and related guidelines.
• Manage the release path: signing, provisioning, build configuration, store submissions.
• Test on real devices across OS versions and devices; ensure coverage beyond simulators.
• Review peers' code with a quality and security lens; keep work visible and well paced.
• Keep documentation current alongside code; SDK usage, platform configuration, and release notes.

Job description

ABOUT THE ROLE

We are seeking a Senior Mobile Developer whose expertise matters more to us than the platform they started on. What we value is depth across the full craft of mobile development: native engineering on both iOS and Android, confident cross-platform work, sharp debugging and root-cause analysis on real devices, secure coding as a habit rather than a checklist, and the engineering judgement to ship production-quality releases to the app stores. Day to day, the work spans feature development, live app support, and work across both native and cross-platform codebases; assignments follow priorities, and a developer with the right skills moves comfortably between them. We hire for breadth and fundamentals over any single framework. We are looking for a developer who has genuinely worked across more than one mobile technology native Android and native iOS, and at least one hybrid or cross-platform framework and whose core programming concepts are strong enough to pick up the next one quickly and deliver production-quality, secure code in it.

KEY RESPONSIBILITIES

• Deliver features and enabler work end to end from story through implementation, testing, and release readiness.
• Own issues end to end investigate, reproduce on real devices, root-cause, fix, and verify, with no regressions left behind.
• Work across both cross-platform and native codebases as the work requires, keeping behaviour and feature parity consistent between them.
• Write secure, clean, production-quality code — built to the OWASP MASVS (Mobile Application Security Verification Standard), no secrets or keys in source control, scan findings acted on promptly.
• Manage the release path: signing, provisioning, build configuration, store submissions, and reproducible builds across environments.
• Test on real devices across OS versions, screen sizes, and platform behaviours before handing work to QA — simulators and emulators alone are not enough.
• Review peers' code with a quality and security lens across both cross-platform and native codebases; take review feedback constructively. Keep work visible and well paced — boards current, blockers raised early, ambiguities cleared before development starts.
• Keep documentation current alongside code — SDK usage, platform configuration, and build and release notes another developer can pick up without chasing you.

REQUIRED SKILLS

• 5+ years of professional mobile development experience, with production apps you have taken through to release on the App Store, Google Play, or both.
• Hands-on experience across multiple mobile technologies, spanning cross-platform and native: - Cross-platform — solid production experience in Flutter, React Native, or both.
• Depth in one with working exposure to the other is what we are looking for; production depth in another framework such as Kotlin Multiplatform, .NET MAUI, NativeScript, or Ionic counts where the fundamentals transfer. - Native — at least one platform — production experience in either native Android (Kotlin and/or Java, Jetpack Compose and/or Views, Android SDK, Gradle) or native iOS (Swift and/or Objective-C, UIKit and/or SwiftUI, Xcode), with the confidence to pick up work in the other platform's codebase as the work requires.
• Strong core programming fundamentals — data structures, design patterns, concurrency and threading, memory management, app architecture (MVVM, MVI, Clean or similar) — with a demonstrated ability to pick up new languages and frameworks quickly.
• Solid API integration skills — REST and GraphQL, authentication flows, real-time communication, and handling poor or intermittent connectivity.
• On-device data and offline-first experience — local storage (Room, Core Data, SQLite, SQLDelight or similar), caching, background sync, and conflict handling.
• Proven security expertise, held to a recognised standard — the OWASP MASVS (Mobile Application Security Verification Standard) and its MASTG testing guide — across secure storage of tokens and keys, cryptography, authentication flows, transport security, platform interaction, and resilience (obfuscation and tamper protection); plus supply-chain and third-party SDK diligence, and acting on SAST and dependency-scan findings.
• Release engineering competence — code signing, provisioning profiles or keystores, build flavours and schemes, store review processes, and staged or phased rollouts.
• Excellent debugging and root-cause-analysis skills on live production apps — crash reporting, profiling, memory and performance analysis, and device-specific issues.
• Unit and UI testing, authored alongside implementation.
• Experience with Git-based workflows, peer code review, and CI/CD for mobile builds.
• Strong sense of ownership across both live app maintenance and planned feature delivery.
