Mobile Solution Architect - (React Native, iOS/Swift, Android/Kotlin) - 100% Remote - W2 Contract
Optomi, in partnership with a leading financial services organization, is seeking an experienced Mobile Solution Architect to lead the architecture and technical integration of a strategic third-party platform into an enterprise-scale consumer banking application.
This role requires a strong understanding of React Native architecture and development, along with deep native iOS and Android engineering expertise. The organization is leveraging React Native to support both iOS and Android applications, so the ideal candidate must understand how React Native interacts with the underlying native platforms, including SDK integrations, authentication, security, and platform-specific functionality.
We're looking for someone who can operate at both the solution architecture and technical engineering levels. This individual should be comfortable collaborating with React Native developers, challenging architectural decisions with senior Swift and Kotlin engineers, and partnering with backend, security, and external technology teams to design a secure, scalable, and maintainable mobile solution.
