Mid-Senior Android Developer - Full Remote Portugal

Job Description

ABOUT THE OPPORTUNITY

Join a global software engineering company working on a prestigious British online fashion retailer's mobile application—a European E-commerce Awards winner with over 10 million downloads. This is a rare opportunity to work on an app that was featured at the Google I/O 2019 Developer Keynote and continues to be showcased in major tech case studies. You'll create exceptional native Android experiences using cutting-edge technology while maintaining world-class quality standards—think gourmet cuisine for mobile development, where every detail is crafted to perfection. Working fully remote from Portugal, you'll collaborate with talented Android, iOS, and QA engineers who thrive in challenging environments and are known for being amazing contributors. 

PROJECT & CONTEXT

You'll be building and maintaining features for a sophisticated e-commerce mobile application that sets industry standards for performance and user experience. The codebase leverages modern Android Architecture Components (ViewModel, LiveData, Room) with a Kotlin-first approach, combining Coroutines and RxJava within Agile frameworks (Scrum and Kanban). Your work will involve creating fluid visual interactions and implementing mobile UX patterns while collaborating directly with the client as one integrated team. You'll discuss technical architecture and design, write testable code ensuring agreed test coverage levels, and take full ownership from development through deployment to production maintenance. The role requires experience working on medium-to-large team environments with apps at considerable scale, as you'll be tackling challenges that come with millions of active users. Expect occasional national and international travel (0-15%) depending on project needs, with opportunities to mentor junior engineers and be integral to solutions design and implementation.

• Client Engagement: Experience collaborating directly with clients to ensure technical feasibility of requirements
• Communication: Good communication skills in Portuguese and English
• Language: B2 English (Upper Intermediate) minimum for client and team collaboration
• Ownership Mindset: Taking full responsibility for code from development through deployment and maintenance

NICE TO HAVE (Preferred)

• Kotlin Multiplatform: Experience sharing code between Android and iOS using Kotlin Multiplatform

• Service-Oriented Architecture: Understanding of SOA, design patterns, and complex data structures
• TDD & CI/CD: Test-driven development practices and continuous delivery pipeline experience
• Production Metrics: Experience with metrics, performance monitoring, and operational aspects showing care for production code
• Mentorship: Previous experience mentoring junior engineers
• Production Troubleshooting: Ability to diagnose production issues and devise effective solutions
