This company is actively engineering next-generation infrastructure aimed at establishing a new paradigm within the international FinTech industry. Operating within a high-agency, fast-paced environment, the successful candidate will work directly alongside cross-functional product and design teams to translate high-fidelity, responsive designs into elegant and highly optimized production software. The ideal candidate possesses an uncompromising standard for engineering craft, a deep product-minded orientation, and a strong sense of user empathy. Speed, execution velocity, and the capacity to pioneer robust architectural choices will position this individual as a foundational pillar of the mobile engineering organization. Furthermore, this role offers the unique opportunity to sit at the forefront of financial technological convergence by exploring and natively integrating Web3 architecture and crypto wallet experiences within the core Android ecosystem. Key Responsibilities Core Application Engineering: Architect, build, test, and safely deploy the client's core native Android application using Kotlin and cutting-edge continuous delivery pipelines. UI/UX Implementation: Translate pixel-perfect, responsive design mockups from Figma into fluid, highly responsive user interfaces utilizing Jetpack Compose and modern Android layout principles. Web3 Integration: Conduct technical exploration, prototyping, and production implementation of Web3 systems and secure, intuitive crypto wallet experiences natively on the Android platform. Code Craftsmanship: Maintain, advocate for, and extend a clean, highly testable, and robust codebase, utilizing automated unit and UI testing frameworks to minimize regression and optimize stability. System Optimization: Drive technical excellence across critical operational requirements, including telemetry/analytics capture, localized translations, and deep memory optimization. Agile Collaboration: Contribute actively within a high-performance, iterative agile lifecycle, maintaining a culture of collective ownership where the team prioritizes collaborative problem-solving over individual finger-pointing. Requirements Proven Track Record: Solid experience in shipping commercial-grade native Android applications to production. While all exceptional technical backgrounds will be evaluated, five or more years of experience building beautiful, high-performance Android applications is highly advantageous. Language & Toolkit Mastery: Advanced engineering proficiency in Kotlin, alongside extensive, hands-on mastery of Jetpack Compose and modern Android UI design libraries. Architectural Sophistication: Deep comprehension of state-of-the-art Android software architectures (e.g., MVVM, MVI) and a passion for crafting clean, scalable, and modular software layers. Rigorous Testing Practices: Deep familiarity with modern testing methodologies, explicitly including unit testing and automated UI testing paradigms. Design Literacy: Strong capability utilizing Figma tools to analyze assets, demonstrating sharp attention to micro-interactions, animations, padding, typography, and visual consistency. Core Optimization Focus: Strong attention to low-level engineering details, including payload optimization, memory footprint reduction, lifecycle management, and application performance monitoring. High Agency & Mindset: An iterative, fast-moving builder mentality with an innate desire to learn, grow, and credit the team for collective milestones. Benefits Exceptional Compensation: A highly competitive base salary paired with a robust equity/stock option package. Comprehensive Healthcare: Premium private health and dental insurance coverage.
