Devency is a leading software development and technology consulting firm based in Egypt, delivering scalable, high-quality solutions across custom software, cloud infrastructure, and IT strategy. We foster a culture of innovation, collaboration, and technical excellence—and we’re looking for a Senior iOS Engineer to architect, scale, and optimize high-performance mobile experiences.

What You’ll Do

Lead Architecture & Development

• Drive the design and implementation of advanced iOS apps using Swift, SwiftUI (and UIKit where appropriate).
• Define and enforce architectural standards (Clean Architecture, MVVM/MVI, modularization, feature flags).

Craft Exceptional UI/UX

• Build responsive, accessible interfaces with SwiftUI (layouts, states, animations, transitions).
• Guide componentization, theming, and design-system adoption; mentor teammates on best practices.

Optimize Performance

• Profile with Instruments (Time Profiler, Memory, Leaks, Energy), eliminate jank/ANRs, improve startup and rendering.
• Design for high-throughput use cases (e.g., chat/real-time feeds, media) with efficient state and caching.

Ensure Quality & Reliability

• Establish testing strategy with XCTest, XCUITest, snapshot tests; champion TDD where it fits.
• Own CI/CD quality gates (Fastlane, GitHub Actions/Xcode Cloud), crash monitoring, and release health.

Integrate & Scale APIs

• Lead integrations using URLSession/Alamofire, Concurrency (async/await), Combine, WebSockets; handle auth, retries, back-off, and error flows.
• Design offline-first data layers (Core Data/SQLite/Realm) with safe migrations and background sync.

Collaborate & Mentor

• Perform rigorous code reviews, pair program, and run knowledge-sharing sessions.
• Partner with product/design to shape scope, sequence work, and uphold engineering standards.

Who You Are

• A senior engineer who can untangle complex problems, make sound tradeoffs, and elevate a team.
• Performance-obsessed and pragmatic, balancing craftsmanship with delivery.
• A clear communicator who thrives in fast-paced, agile environments.
