About the Role
We're looking for an iOS Engineer to build the native iOS 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 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
iOS Application Development
Design, build, and maintain core features using Swift and modern iOS frameworks (SwiftUI, UIKit, Combine, Swift Testing, Swift Data). Deliver smooth, intuitive user experiences that support complex financial workflows. Own feature development end-to-end—from architecture to implementation, testing, and release, including TestFlight builds and deployment to the Apple App Store.
Architecture & Scalability
Establish scalable iOS application leveraging SwiftUI architectural patterns such as async/await and data flows. Optimize performance, responsiveness, offline/online behavior, and data persistence. Build for speed and correctness in a regulated environment.
Integration & Data Handling
Integrate the mobile client 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.
