What you’ll be doing

Reporting to the Squad lead, the Mobile Developer will be responsible for designing, building, and delivering native iOS and Android applications for a new customer portal experience. They will work closely with the existing responsive .NET/React web application, reusing the application, APIs, patterns, and product experience wherever practical while delivering high-quality native mobile apps that meet customer, platform, security, and performance expectations. They will embody Reapit’s core values of Trust, Collaboration, Innovation, Excellence, and People.

Key Responsibilities:

Planning and Requirement Analysis:

Collaborate Across Departments: Work closely with product managers, designers, QA, web engineers, and backend engineers to define mobile requirements, platform considerations, and delivery priorities.

Requirement Analysis and Estimation: Analyse customer portal functionality and identify the best approach for delivering it on mobile, balancing native implementation, reuse of existing web capability, and platform-specific user experience.

System Design:

Mobile Architecture and Implementation: Design mobile solutions that integrate with the customer portal and supporting services, ensuring security, scalability, maintainability, accessibility, performance, and an experience that feels appropriate on both iOS and Android.

Implementation:

Mobile App Development and Review: Build, maintain, and review native iOS and Android application code, contributing to shared standards, patterns, and reusable components where appropriate.

Testing and Validation: Perform rigorous testing and validation across devices, operating system versions, network conditions, and app lifecycle scenarios to ensure reliable mobile delivery.

Documentation: Develop and maintain accurate documentation for mobile architecture, platform decisions, release processes, integration points, and operational support.

Project Delivery:

Agile Participation: Actively participate in agile ceremonies, including daily stand-ups, sprint planning, retrospectives, and reviews.

Project Delivery: Deliver mobile features to agreed timelines and quality standards, supporting beta testing, release readiness, and app store submission activities.

Maintenance:

Technical Guidance: Provide mobile development guidance to the squad, helping the team make pragmatic decisions about native capability, web reuse, mobile user experience, and platform constraints.

Continuous Improvement: Identify and implement opportunities to improve mobile performance, reliability, accessibility, maintainability, automation, and developer productivity.

Operational Support: Assist with the investigation and resolution of mobile issues, including crashes, defects, performance concerns, release issues, and customer-impacting incidents.

Who we're looking for

At Reapit, we prioritise hiring individuals who share our values and possess the right attitudes and behaviours for success. Whilst some of the listed requirements may be important, don’t worry if you don’t meet all of them, we’d still like to hear from you.

Qualifications and Experience:

Bachelor’s degree in computer science, engineering, or a related field, or equivalent practical experience.

5+ years in mobile software development, with proven experience delivering production applications for iOS and Android - Essential

Experience building native mobile apps using Swift/SwiftUI for iOS and Kotlin/Jetpack Compose or equivalent Android frameworks - Essential

Experience integrating mobile apps with RESTful APIs, web-based customer experiences, authentication flows, and shared backend services.

Technical

Native iOS (Swift) and Android (Kotlin) fundamentals

Cross-platform wrapper frameworks (Capacitor / Cordova / React Native WebView) — experience with at least one in production

In-app purchases: StoreKit 2 and Google Play Billing — products, subscriptions, receipt/purchase validation with backend, restore flows, sandbox testing

Payment compliance: Apple/Google IAP policy vs. external payment rules.

Push notifications, deep links / universal links, app permissions

Native device integrations as needed (camera, file upload, biometrics, secure storage)

REST/GraphQL API integration and debugging with backend teams.

Comfortable translating Figma into native shell UI and flagging gaps early

Self-managing on timelines and risk reporting; can commit to a fixed 12-month scope

Nice to have
