About Monstro

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.

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, Android

X, 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.

What We’re Looking For

• 8–12+ years of professional Android development experience, with a demonstrated history of leading the design and evolution of large‑scale Android systems and influencing the technical direction of high‑impact, long‑lived products.
• Expert‑level Kotlin and Android platform expertise, with the ability to set standards and best practices for modern Android development across multiple teams.
• Proven ownership of cross‑cutting Android initiatives (e.g., shared frameworks, platform migrations, architectural overhauls), driving work from ambiguous problem definition through sustained adoption.
• 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, Android
  
  X, Coroutines, and related tooling, with a track record of introducing or scaling these technologies across teams.
• Recognized expertise in…
