React Native Mobile Developer

Senior React Native Mobile Developer

6-Month Contract | Sandton | Onsite

Rate:
Up to R500 per hour

We are looking for an experienced React Native Mobile Developer to join a high-performing technology environment within a leading financial services organisation.

This is a 6-month contract opportunity based onsite in Sandton and is suited to a strong mobile developer who has delivered production-grade React Native applications end-to-end
.

This is not a web-focused React role. We are specifically looking for candidates with solid, hands-on React Native mobile development experience
, including testing, build automation, application signing and deployment to the Apple App Store and Google Play Store.

• Develop, enhance and maintain production React Native mobile applications.
• Build scalable, reliable and high-performing mobile features using React Native, Type Script and Redux Toolkit
  .
• Integrate mobile applications with REST APIs and backend services.
• Manage application state, performance and the Redux lifecycle.
• Develop and maintain automated unit, integration and end-to-end testing.
• Support mobile CI/CD pipelines, automated builds and release processes.
• Manage application signing, certificates and production releases.
• Deploy and manage applications through App Store Connect, Test Flight and Google Play Console
  .
• Work closely with engineering, product and technical teams within an Agile delivery environment.
• Troubleshoot mobile-specific issues across iOS and Android platforms.

Candidates must have strong commercial experience with:

• React Native 0.80+ – 0.78+ will be considered
• Expo
• Redux Toolkit (RTK)
• Type Script / modern Java Script
• REST API integration
• Mobile state management and performance optimisation

Hands-on experience with:

• Jest
• React Native Testing Library (RNTL)
• Detox
• Maestro

Candidates should have a good understanding of:

• Native iOS and Android integrations
• Mobile application architecture
• App lifecycle and performance
• Production debugging and troubleshooting

Experience with
Swift and/or Kotlin will be advantageous.

Experience in the following will be highly advantageous:

• CI/CD pipelines, ideally Azure Dev Ops or similar
• Automated testing within deployment pipelines
• Mobile build and release automation
• App Store Connect
• Test Flight
• Google Play Console
• App signing and certificate management
• Production application publishing and release management

The successful candidate will have personally contributed to delivering React Native applications into production
, rather than having only limited React Native exposure as part of a predominantly web-based React role.

You should be comfortable working across the full mobile delivery lifecycle:

Development → Testing → Build Pipeline → Signing → Release → App Store / Play Store Deployment

• Due to the nature of the environment, successful candidates will be required to undergo screening and must be able to obtain satisfactory:

• Criminal clearance
• Credit clearance

If you are an experienced React Native Developer with proven production mobile delivery experience and are available for a contract opportunity in Sandton, we would like to hear from you.
