- Lead the integration of Backbase Mobile SDKs (e.g., Identity, Authentication, Transactions) into Flutter through native bridges or wrappers.

- Participate and lead in solution design, backlog grooming, sprint planning, and technical sessions.

- Identify technical risks early and proactively propose mitigation plans (e.g., PoC, API contracts, architectural patterns).

- Ensure CI/CD pipeline readiness, quality gates, and secure mobile delivery practices are applied from day one.

- Champion adherence to Backbase API specifications and design system principles wherever feasible.

- Ensure all visual designs conform to API contracts and UX standards.

- Guide other developers and review code for scalability, modularity, and quality.

Required Skills & Experience :

- Strong understanding of Flutter's core concepts (widgets, state management, navigation, animations).

- Solid understanding of native mobile app lifecycles (iOS and Android), SDK integration, and platform constraints.

- Understanding of performance best practices, identifying bottlenecks, and optimizing app performance.

- Understanding of local storage solutions (like SQLite) for storing and managing data locally.

- Experience integrating RESTful APIs and authentication mechanisms in mobile apps.

- Proven background in at least one Flutter-based production deployment at scale. Proficiency in performance tuning, offline capabilities, local storage, threading, and security best practices.

- Proficient in DevOps concepts (e.g., GitLab CI/CD, Firebase, Bitrise) and test automation for mobile.

- Excellent problem-solving skills and debugging techniques across hybrid/native integrations.

- Strong English communication skills (verbal and written) with ability to clearly articulate technical issues and decisions.

Additional Skills :

- Experience with Backbase platform SDKs and digital banking implementation projects.

- Experience with building apps for both Android and iOS.

- Familiarity with strategies around native SDKs for use in hybrid frameworks.
