Working in a collaborative, cross-functional Agile environment, you will partner closely with product managers, UI/UX designers, QA engineers, and backend cloud teams to deliver high-quality code and maintain robust CI/CD deployment pipelines. This role is ideal for a senior mobile engineer who combines hands-on technical excellence with mentorship and software engineering best practices.

Native Module Integration: Build and maintain native modules in Swift (iOS) and Kotlin (Android) as needed to integrate platform-specific features into the React Native framework.

API & Backend Integration: Connect mobile frontends with RESTful APIs, GraphQL endpoints, Firebase services, and enterprise cloud infrastructure.

Quality, CI/CD & Team Enablement
Performance & Optimization: Profile and optimize app responsiveness, memory utilization, render speeds, and asset consumption.

CI/CD Pipeline Maintenance: Implement, support, and maintain automated build and deployment pipelines for mobile releases using Git/Azure Repos and CI/CD tooling.

Code Quality & Mentorship: Conduct thorough peer code reviews, enforce coding standards, mentor junior developers, and foster engineering excellence.

Agile Collaboration: Participate actively in Scrum ceremonies, translating complex business requirements into clear technical designs and actionable user stories.

Qualifications
Software Engineering Experience: 6+ years of professional software development experience, with at least 4+ years dedicated to React Native delivering production applications at scale.

Core Programming Languages: High proficiency in JavaScript (ES6+) and TypeScript.

Mobile Architecture & State Management: Solid command of mobile architecture, state management frameworks (Redux, MobX, or Recoil), and navigation libraries (React Navigation).

Native Platform Literacy: Direct experience with native iOS (Swift / Objective-C) and/or Android (Kotlin / Java) development for platform-specific React Native integrations.

Tooling & CI/CD Pipelines: Hands-on experience with Git/Gitflow, Azure Repos, CI/CD deployment pipelines, and mobile build utilities.

Security & APIs: Strong understanding of RESTful API design, Firebase, and mobile security standards.

Testing & Quality Assurance: Familiarity with mobile testing frameworks such as Jest, Detox, or Appium.

Soft Skills: Exceptional problem-solving and debugging abilities; strong verbal and written communication skills with a proven track record of collaborating across cross-functional teams.

Preferred Assets & Nice-to-Haves
Experience with Python scripting or backend development.

Knowledge of GraphQL and Apollo Client integrations.

Experience with mobile analytics platforms, A/B testing frameworks, and feature flag management.

Familiarity with major cloud environments (GCP, AWS, or Azure) and mobile app observability platforms (e.g., New Relic).

Summary
If you are a tech-savvy Senior React Native Developer who pairs an absolute command of TypeScript, mobile architecture, and native iOS/Android module development with the CI/CD and performance optimization skills needed to power large-scale consumer applications, this 2-month contract is an outstanding opportunity. Bring your mobile engineering precision, clean code standards, and collaborative leadership style to our client's digital engineering team today!
