Mobile Engineer – React Native

Mobile Software Engineer

Lendi Group is a market-leading digital platform business focused on transforming the home loan industry. It operates the country's #1 retail mortgage broker – the iconic Aussie Home Loans franchise – and the Australia's #1 digital mortgage brand, Lendi.

Together, with its national network of 1,300 brokers and 230 retail stores, the Lendi Group brands give all Australians the power of choice, and confidence, in one of life's biggest financial decisions.

Building on this market-leading foundation, Lendi Groups vision is to be the undisputed place for Australians to buy and own property through our new Aussie Homes propositions.

Diversity, Equality, and Inclusion are fundamental to the success of Lendi Group. We're passionate about fostering an environment where our team members feel valued and supported and we celebrate everyone's unique identity.

Lendi Group is seeking a Mobile Software Engineer to help build secure, reliable and performant mobile experiences for Australians navigating property buying and home finance. You'll work closely with product, design and backend engineers 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). Curiosity about these approaches is welcome; prior experience is a bonus, 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 Sydney-based role involves working on-site at our Head Office 2 days per week to collaborate on a fast-moving initiative.

Feeling like you don't tick every box? Please consider applying, we value potential, a learning mindset and transferable experience.

Job Description

• Contribute to the development and evolution of our React Native app across key customer and broker journeys.
• Write clean, maintainable TypeScript/React Native code with secure-by-default practices.
• Own well-scoped features end-to-end: requirements, implementation, testing and release support.
• Collaborate with product, design and backend engineers to integrate APIs and ensure a smooth cross-platform experience.
• Build with a security mindset: follow secure storage/transport patterns and handle sensitive financial data with care.
• Instrument what you build: add analytics events, structured logs and crash reporting; help monitor dashboards.
• Participate in code reviews, contribute to CI/CD workflows, and keep the codebase healthy through small, continuous refactors.
• Support releases and help triage production issues with guidance from senior engineers (runbooks, feature flags/kill-switches).
• Learn from and collaborate with senior engineers; optionally mentor interns or juniors on specific tasks as you grow.
• Exposure to SKAdNetwork, AdAttributionKit, App Tracking Transparency (ATT) and Meta attribution flows.

Qualifications

• 2–4 years of professional software development, including 2+ years of commercial React Native (TypeScript) experience.
• Shipped and supported production apps on iOS and/or Android; familiarity with platform tooling, app lifecycles and app store processes.
• Secure mobile development fundamentals: encryption in transit/at rest, Keychain/Keystore basics, and awareness of OWASP mobile guidance.
• Authentication & authorisation: practical experience integrating OAuth 2.0/OpenID Connect and handling sessions on mobile.
• Solid testing habits: write and maintain unit/component tests and run them in CI.
• Backend integration experience (REST and/or GraphQL), including auth flows, resilience and error handling.
• A pragmatic approach to production ownership: telemetry, debugging and incident mitigation alongside senior engineers.
• Clear, considerate communication and a collaborative approach with product/design/QA and other engineers.
• Hands-on experience with mobile growth and reliability — push notifications, deep linking, analytics, and automated release pipelines.
• Awareness of security, privacy, and regulated environments — especially fintech or Australian financial systems.
• Curiosity for innovation — from AI-assisted development to continuous testing and performance optimisation.
