Core Responsibilities

Primary Functions

Lead the design, architecture, development and delivery of advanced Android applications, ensuring high‑quality, maintainable, scalable implementations.
Define and implement mobile architecture best practices for Android, including MVVM/MVP/Clean Architecture patterns, modularised codebases, dependency injection, reactive programming and UI components.
Oversee and participate in full mobile application lifecycle: requirements gathering, design, development, testing, release, monitoring and iteration.
Partner closely with product managers, UX/UI designers and backend engineers to translate business and user requirements into mobile features and roadmaps.
Mentor and guide a team of Android developers: conduct code reviews, lead technical discussions, set standards, support career growth and ensure engineering excellence.
Establish, maintain and evolve the Android build, deployment and release infrastructure (CI/CD, version control, Play Store releases, beta channels) to ensure smooth and fast delivery.
Improve application performance and stability: identify and resolve bottlenecks, memory leaks, UI jank, slow startup times and ensure optimal behavior across devices and Android versions.
Drive adoption of modern Android frameworks and tools: Jetpack Compose, Android Jetpack libraries (LiveData, ViewModel, Room, Navigation), Kotlin coroutines and flows, Android X.
Ensure the Android applications adhere to high standards of security, data protection, encryption, secure storage, authentication/authorization and platform compliance.
Monitor and maintain production mobile applications: track user metrics, crash reports, feedback, iterate quickly on fixes and updates to meet SLA and user expectations.
Lead efforts in device compatibility, screen size variations, OS version fragmentation, locale and accessibility (e.g., WCAG) support to deliver inclusive mobile experiences.
Keep the Android app aligned with analytics, instrumentation and telemetry: integrate SDKs, interpret data, use insights to prioritize features and improvements.
Manage technical debt: evaluate legacy code, refactor critical parts, introduce automation (unit/integration/UI tests), static analysis (lint, ktlint) and maintain code hygiene.
Lead and contribute in agile ceremonies: sprint planning, backlog refinement, stand‑ups, retrospectives, estimation and prioritization of tasks.
Research, evaluate and adopt new mobile technologies, frameworks, libraries and patterns; propose proof‑of‑concepts, pilot projects and toolchain improvements.
Optimize the Android app for store readiness: Play Store guidelines, app bundle sizes, asset optimization, A/B testing, release strategy and localization/internationalization.
Collaborate with DevOps and infrastructure teams to ensure mobile backend APIs, BFF layers, GraphQL/REST endpoints and microservices integrate efficiently with the Android client.
Ensure cross‑functional alignment: liaise with QA, operations, support, marketing and business stakeholders to ensure release readiness, feature quality and user satisfaction.
Drive the Android team culture: promote code quality, automated testing, peer review, documentation, continuous learning, and maintain a high‑functioning, motivated engineering team.
Report on mobile engineering metrics, road‑map status, risks, dependencies and ensure transparency and alignment with senior leadership and business stakeholders.

Secondary Functions

Support ad‑hoc data requests and exploratory analytics for user behaviour, app performance or mobile feature evaluation.
Contribute to the organisation’s mobile technology strategy and roadmap for Android platform and mobile architecture.
Collaborate with business units (marketing, customer success, operations) to translate mobile requirements into engineering tasks and prioritize backlog accordingly.
Participate in sprint planning and agile ceremonies within the mobile engineering team to ensure efficient delivery cycles.
