Job description

As a Senior Android Developer, this individual contributor role will design, develop, and deliver high-quality native Android applications using Kotlin and Java. The role requires deep hands‑on expertise in Android platform capabilities, application lifecycle, architecture patterns, performance optimization, secure coding practices, and modern development standards while partnering with product, design, backend, cloud, QA, infrastructure, security, and operations teams to build reliable and scalable mobile solutions for store operations and customer-facing experiences.

This is a 5 day onsite role.

Key Responsibilities

• Design, develop, and maintain native Android applications using Kotlin and Java with a focus on reliability, scalability, performance, and maintainability.
• Apply strong Android fundamentals across application lifecycle, activities, fragments, services, broadcast receivers, background execution, permissions, storage, networking, and device compatibility.
• Implement clean, modular Android architecture using MVVM, Clean Architecture, dependency injection, repository patterns, and reusable component design.
• Build intuitive and responsive mobile experiences that support multiple screen sizes, device form factors, orientations, and Android OS versions.
• Profile, troubleshoot, and optimize applications for memory usage, startup time, network efficiency, battery consumption, threading, and runtime performance.
• Conduct device performance testing across target Android hardware, including responsiveness, CPU and memory usage, battery impact, network behavior, startup time, and real store operating conditions.
• Implement secure mobile development practices for permissions, certificates, encrypted storage, authentication tokens, API communication, and sensitive data.
• Integrate Android applications with REST APIs, cloud services, backend microservices, databases, and enterprise systems with resilient error handling and offline or limited‑connectivity support.
• Write unit tests, integration tests, and automated UI tests to improve quality, maintain code coverage, and support reliable releases.
• Participate in code reviews, enforce coding standards, improve development practices, and mentor developers on Android engineering best practices.
• Support CI/CD, release management, build automation, crash analysis, monitoring, and production troubleshooting for Android applications.
• Primary focus is native Android development in Kotlin and Java.
• Collaborate closely with product owners, designers, QA, backend engineers, security, infrastructure, and operations teams to define requirements, assess tradeoffs, and deliver production‑ready solutions.
• Evaluate open‑source libraries, Android platform capabilities, device SDKs, and market solutions to accelerate delivery while managing technical risk.
• Support production troubleshooting, release readiness, and quality delivery for Android applications used in store technology environments.

Years of Experience

• 12+ years of overall software engineering experience.
• 7+ years of hands‑on native Android application development experience using Kotlin and/or Java.

Required Qualifications (Non‑Negotiable)

• 7+ years of hands‑on native Android application development experience using Kotlin and/or Java.
• Strong understanding of Android SDK, Android framework components, application lifecycle, permissions, storage, threading, background execution, networking, and device compatibility.
• Experience designing Android applications using scalable architecture patterns such as MVVM, Clean Architecture, dependency injection, and modular code organization.
• Experience with RESTful API integration, JSON, authentication flows, error handling, offline storage, caching, and limited‑connectivity scenarios.
• Experience profiling and tuning Android applications for memory, performance, responsiveness, battery usage, and crash reduction.
• Experience planning and executing device performance testing on Android hardware, including benchmarking, profiling, load testing, battery analysis, and identifying device‑specific performance constraints.
• Experience with unit testing, test‑driven development practices, automated UI testing, and maintaining reliable code coverage.
