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.

Key Responsibilities

• 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, TestFlight and Google Play Console .

• Work closely with engineering, product and technical teams within an Agile delivery environment.

The Ideal Candidate

You should be comfortable working across the full mobile delivery lifecycle: Development → Testing → Build Pipeline → Signing → Release → App Store / Play Store Deployment
