About The Position

Monstro is an AI-native fintech platform reimagining how people and institutions manage money. We’re building a modern foundation for financial decision-making—combining intelligence, automation, and elegant design to help users make smarter choices with confidence. Our team includes experienced builders from leading fintech, wealth management, and technology companies, united by a shared goal: to create a category-defining product that transforms how financial insight is delivered and acted on. About the Role We’re looking for a seasoned Staff level Android Engineer to join our founding team building the native Android experience for our financial platform. You’ll design and deliver secure, high-performance features that help users understand and manage their financial lives, while laying the foundation for a long-term mobile architecture. This is a hands-on, collaborative role where your work will directly shape the core experience our users rely on every day. Why This Role Matters Monstro’s mobile app is central to how users interact with their financial universe. Your work will help define the quality, responsiveness, and trustworthiness of that experience. The systems you build must be secure, elegant, and resilient—handling sensitive financial data at scale while remaining intuitive and reliable. What You’ll Do Android Application Development Design, build, and maintain core features using Kotlin and modern Android frameworks (Jetpack Compose, AndroidX, Coroutines). Deliver smooth, intuitive user experiences that support complex financial workflows. Own feature development end-to-end—from architecture to implementation, testing, and release. Architecture & Scalability Establish architecture patterns (MVVM, MVI, Clean Architecture) that support speed, maintainability, and long-term scale. Optimize performance, responsiveness, offline/online behavior, and data persistence. Build for speed and correctness in a regulated environment. Integration & Data Handling Integrate mobile clients with backend APIs, financial data systems, and third-party providers. Work closely with backend engineers to shape efficient API interactions and ensure seamless real-time data flows within the app. Security & Compliance Implement secure data handling practices required for financial applications. Ensure proper encryption, secure storage, authentication flows, and session management. Build with the rigor necessary for regulated, high-trust environments. Collaboration & Execution Partner with product managers, designers, and fellow engineers to deliver cohesive, user-centered features. Contribute to architectural discussions, planning, and code reviews. Support engineering excellence through documentation, testing, and raising the overall technical bar. What Success Looks Like The Android experience is fast, secure, and reliable—earning user trust through performance and clarity. The codebase is clean, scalable, and adaptable to rapid iteration and future features. Architecture patterns are consistent, documented, and adopted across mobile engineering. The app consistently meets Monstro’s standards for performance, security, and usability in a regulated environment. Collaboration, documentation, and technical rigor are elevated across the team through your example.
