This is an opportunity to shape the Android side of a truly emerging product, where your work will directly power how clients and users first experience their AI innovations. The RoleAs the Senior Android Engineer you’ll take full ownership of the Android migration process, bringing all existing iOS functionalities into the Android ecosystem.In your first 3–6 months, your mission will be to migrate the iOS app to Android, ensuring feature parity, smooth performance, and clean architecture. You’ll also help lay the groundwork for future expansion to tablets and wearable devices.Beyond migration, you’ll design and build new Android apps and SDKs that enable AI experimentation and client integration, ensuring users have a seamless and robust experience.This is not your typical app dev role, you’ll be working at the intersection of Android engineering, SDK development, and applied AI, helping to shape products that are literally the first of their kind.If you’re a Kotlin specialist who thrives on ownership, architecture, and building clean, scalable mobile systems, this is your lasting opportunity to leave a visible impact on a truly emerging technology. Key ResponsibilitiesLead the migration of all iOS functionalities into Android — taking complete ownership of the process.Develop Android applications and SDKs that enable client integration with cutting-edge AI technology.Collaborate cross-platform with iOS engineers to ensure consistency and parity.Architect Android solutions that are scalable, maintainable, and testable (Hexagonal Architecture, clean code principles).Work closely with AI researchers to bring experimental models to life on mobile devices.Potentially expand development to tablet and wearable platforms. What We’re Looking For:Technical Must-Haves:Proven commercial experience as an Android Engineer or Android DeveloperDeep proficiency in Kotlin and hands-on experience with the Android SDK.Strong understanding of modern app architecture and clean, testable code.Familiarity with CI/CD automation tools (e.g. GitHub Actions, Pulumi).Experience with AI, biometrics, or behavioural technology is a major plus.Nice to have: iOS/Swift experience or willingness to pick it up for future cross-platform needs.Soft Skills & Cultural Fit:Self-driven and able to work autonomously.A practical problem-solver who enjoys tackling complex challenges.Collaborative and humble — confident in your abilities but not ego-driven.Strong communication skills, able to work seamlessly with quieter team members.Preferred Experience:Prior experience in B2B environments (with longer, more deliberate release cycles) over B2C.Track record of taking ownership of Android roadmaps and delivering high-quality results. Top Priorities in the First 6 MonthsMigrate all existing iOS functionalities to Android.Own and lead the Android development process.Deliver quickly to meet client needs and enable product growth. This role offers two exciting long-term paths:Own the Android function within the company, becoming the go-to technical authority.Progress into a Senior Principal Software Engineer role covering both Android and iOS platforms.You’ll also gain exposure to applied AI, biometrics, and behavioural computing — areas growing rapidly across global tech markets. Why JoinBe part of an early, high-impact engineering team driving a new category of AI.Collaborate with a world-class team in AI research, design, and product development.Shape Android architecture from the ground up with freedom and autonomy.Competitive compensation, hybrid flexibility, and long-term growth potential.
