Senior iOS Developer

Job Description Roles & Responsibilities Develop new iOS features that enable users to connect, configure and control latest devices manufactured by client (sensors, motors, networked appliances). Collaborate with cross-functional teams: firmware/embedded engineers, cloud/API engineers, UX/UI designers, QA/test automation. Maintain and extend the iOS app's architecture: modules, flows, connectivity layers, UI, state-management. Ensure code quality, testability, performance, maintainability and UX excellence. Help onboard new hardware integrations: device discovery (Bluetooth/WiFi), pairing, firmware update flow, cloud sync. Diagnose, debug and resolve issues (connectivity, Bluetooth/WiFi, intermittent network, memory/performance). Participate in code reviews, design discussions, architecture improvements and mentor more junior team members. Support the full mobile app lifecycle: feature definition, development, internal test, App Store release, user feedback, maintenance. Advocate best practices (unit testing, UI testing, continuous integration, modular design, version control). Skills Must have Strong experience (5+ years) developing native iOS apps using Swift, including a solid understanding of iOS SDK, UIKit/SwiftUI. Experience integrating and working with hardware-connected devices (e.g., Bluetooth LE, WiFi modules, IoT, pairing workflows) or, at a minimum, strong awareness of connectivity flows. Proven track record building production-quality apps: modular architecture, clean code, maintainability, testability. Familiar with asynchronous programming (e.g., Combine, RxSwift, async/await) and managing event streams / asynchronous flows. Familiar with RESTful APIs or cloud services, JSON serialisation/deserialisation, handling network failures, caching, offline behaviour. Knowledge of modular architecture patterns (MVVM, Coordinators, Clean Architecture). Knowledge of the MQTT protocol Experience with version control (Git), CI/CD pipelines, unit tests (XCTest/XCUITest) and preferably UI/automation tests. Good understanding of memory management, threading, performance optimisation, and experience resolving common mobile/mobile-device connectivity issues. Ability to work collaboratively in an agile/scrum team, communicate effectively with non-technical stakeholders and device-engineering teams. Fluent in English and able to pick up product/firmware dependencies quickly. Nice to have Experience with SwiftUI and/or migrating legacy UIKit code to SwiftUI. Experience with RxSwift or other reactive frameworks, or familiarity with Combine. Experience with IoT platforms / connected-device ecosystems (device discovery, provisioning, over-the-air updates, telemetry). Familiarity with Bluetooth LE (BLE) protocols, WiFi provisioning, network security, and/or embedded/firmware interaction. Experience using dependency-injection frameworks, modularisation (multiple modules in an app), and using Swift Package Manager or CocoaPods. Familiarity with automated UI testing (XCUITest) and performance/profiling tools (Instruments). Experience in consumer hardware or smart home domain for example, appliances, sensors, robotics. Familiarity with analytics/telemetry frameworks, feature-flagging, remote config, and crash-reporting. Experience working in geographically distributed teams or multi-region apps.
