Staff Mobile Engineer – Android

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.

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.

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.

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.

• Demonstrated ability to define, evolve, and steward Android architecture (e.g., MVVM, MVI, Clean Architecture) at a system and ecosystem level, making informed tradeoffs across product velocity, scalability, performance, and long-term maintainability
• Deep experience with modern Android frameworks and libraries, including Jetpack Compose, AndroidX, Coroutines, and related tooling, with a track record of introducing or scaling these technologies across teams
• Recognized expertise in Android security and data protection, including encryption, authentication/authorization flows, key management, and platform security best practices, with responsibility for setting security direction and reviewing high-risk designs
• Demonstrated ability to diagnose and resolve complex issues related to performance, memory, threading, and real-world device constraints
• Exceptional communication and influence skills, with the ability to align engineers, product managers, designers, and leadership around technical strategy and tradeoffs in complex, fast-moving environments
• Ability to lead by example, conduct high-quality code reviews, mentor engineers, and help raise the overall technical bar
• Genuine passion for building high-quality software, with a continuous improvement mindset and curiosity to stay current with Android platform evolution
