About the Role

We are working on a fintech platform delivering secure, high-performance native mobile applications with real-time financial data and Core Banking integrations. The platform covers two key workstreams: native mobile SDK standardization and Personal Finance Management (PFM) features.

The team operates with an AI Agent-Driven development approach - AI agents are actively used in daily workflows for development, testing, and quality assurance.

📍Work Location: Onsite at Le Ngoc Han, HBT, Ha Noi

Responsibilities

• Develop and maintain native mobile applications (iOS / Android)

• Implement PFM features involving financial data, transaction categorization, and real-time data flows
• Integrate mobile applications with backend services, Core Banking connectors, REST APIs, and event-driven systems
• Handle sensitive mobile flows including OTP verification, eKYC, and secure authentication with appropriate care and judgment
• Collaborate with backend engineers, QA, and product teams to deliver end-to-end features
• Troubleshoot and optimize application performance, data synchronization, and edge case handling
• Participate in code reviews and contribute to improving engineering practices
• Apply AI agent-based development approaches in daily workflows - using agents to implement from spec, generate tests, and handle refactoring tasks, while owning architectural decisions and business logic review

Requirements

• 3-5 years of experience in mobile development (iOS or Android)
• Strong experience with:
• iOS: Swift / UIKit (SwiftUI is a plus)
• Android: Kotlin / Java
• Solid understanding of native mobile architecture (MVC, MVVM, Clean Architecture) and backend integration patterns
• Experience working with REST APIs; familiarity with real-time or event-driven systems is a plus
• Experience in debugging, performance optimization, and writing testable code
• Hands-on experience using AI coding tools (e.g. Claude Code, Kiro, Cursor, GitHub Copilot) in real development work
• Comfortable working in an environment where AI agents are part of the daily development workflows
• Solid understanding and application of secure coding practices, including secrets management, access control, and handling of sensitive data throughout the software development lifecycle.
• Strong awareness of protecting source code, technical documentation, and customer data, while complying with company information security policies in a remote working environment.
• Ability to collaborate with QA/IT/ISRM teams to remediate vulnerabilities, address information security risks, and support incident investigation when required.

Nice to have

• Experience working with banking SDKs or financial system integrations
