To learn more about life at Lendi Group check out our blog : About the role We're looking for a Senior Mobile Engineer (React Native) who's available to start immediately on a contract engagement. There's also potential for this role to transition into a Senior or Lead position on a full-time, permanent basis. This is a great opportunity to take ownership of Lendi Group's mobile engineering direction and join a talented team of React Native engineers working on our new Lendi app leveraging AI features and next-gen user experiences. You'll balance hands‑on engineering with technical leadership, guiding a growing team across Sydney, Brisbane, and Adelaide. You'll influence mobile strategy, mentor engineers, and drive architectural decisions to ensure our apps remain reliable, secure, and performant at scale. You'll work at the intersection of product, design and engineering to deliver features that customers and brokers love, operating in a trusted, regulated domain where quality and security matter. We're progressively moving towards AI-native ways of working (using both AI tools and agents). Experience with agentic ways of working is a bonus, but not a requirement. For a feel for our current mobile tech stack, we use React Native, TypeScript, Zustand, React Navigation, Auth0, Reanimated, Zod and Ky. This is a unique opportunity to influence our mobile platform and engineering practices at national scale. Job Description Take full ownership of our React Native app as it evolves into the core platform for customer and broker journeys. Write clean, maintainable TypeScript / React Native code with strong attention to secure-by-default practices. Design, implement and own significant parts of the app architecture (navigation, data / domain layers, module boundaries, native integrations). Collaborate with product, design and backend engineers to ship end-to-end features, integrating APIs and ensuring a smooth cross-platform experience. Build with a security mindset : threat modelling, least-privilege data access, and careful handling of sensitive financial data. Instrument, monitor and support what you build : analytics, structured logging, crash reporting, performance profiling and alerting. Contribute to CI / CD, code reviews, automated testing and continuous refactoring to keep the codebase healthy. Attribution : practical experience with SKAdNetwork, AdAttributionKit, App Tracking Transparency (ATT) and Meta attribution flows. Mentor and support other mobile engineers; help drive best practices within a collaborative, cross-functional team. Qualifications Around 5+ years of professional software development, with significant, current commercial experience in React Native (TypeScript). Proven delivery of production apps on both iOS and Android with deep platform knowledge (tooling, app lifecycles, app store processes). Secure mobile development fundamentals : encryption in transit / at rest, Keychain / Keystore usage, safe storage & transport of sensitive data, and familiarity with OWASP mobile guidance. Authentication & authorisation : working knowledge of standards such as OAuth 2.0 / OpenID Connect and robust session management on mobile. Strong testing discipline : unit and component tests running in CI; comfort maintaining test suites as the app scales. Backend integration experience (REST / GraphQL), including auth flows, resilience and error handling. Production ownership : telemetry, debugging, incident mitigation and post-incident improvement (runbooks, feature flags / kill-switches). Clear, considerate communication and a collaborative approach to working with product / design / QA and other engineers. Must be available to start immediately. Nice-to-haves Deep React Native expertise – large-scale apps, modern architecture, upgrades to the New Architecture, and hands‑on performance optimisation. Strong platform experience – deep linking, push notifications, analytics, experimentation, and mobile-web feature parity. Proven delivery quality – CI / CD pipelines, automated testing (Detox), and large-scale release management. Solid security and privacy mindset – safe logging, secure storage, and privacy-by-design practices, ideally in fintech or regulated environments. Interest in AI-assisted development and agent-based tooling to accelerate delivery and code quality. Additional Information Lendi Group teams operate across Australia and the Philippines.
