Senior React Native Developer information

What does a senior React Native developer do?

A Senior React Native Developer is responsible for designing, building, and maintaining mobile applications using the React Native framework. They lead the development process, mentor junior developers, and ensure code quality through best practices and code reviews. Additionally, they collaborate with designers and backend engineers to deliver seamless, high-performance apps for both iOS and Android platforms. Their expertise allows them to solve complex problems, optimize app performance, and stay updated with the latest mobile development trends.

What are the key skills and qualifications needed to thrive as a senior React Native developer, and why are they important?

To thrive as a Senior React Native Developer, you need advanced proficiency in JavaScript, React Native, mobile app architecture, and a solid understanding of iOS and Android development, typically supported by a degree in computer science or related experience. Expertise with tools like Redux, TypeScript, RESTful APIs, and familiarity with CI/CD systems or relevant certifications is highly valued. Strong problem-solving, leadership, and communication skills help you collaborate effectively and mentor junior developers. These skills ensure robust, high-quality mobile applications and smooth project delivery in dynamic development environments.

What are some common challenges a senior React Native developer faces when integrating native modules into a cross-platform app?

Senior React Native Developers often encounter challenges when bridging native modules, such as ensuring seamless communication between JavaScript and platform-specific code (iOS/Android). Debugging and maintaining consistency across both platforms can be complex, especially when dealing with device-specific functionalities or third-party libraries. Collaboration with native developers is frequently required to address these issues, and strong documentation skills are essential for maintaining scalable, maintainable code. Staying up-to-date with React Native updates and community best practices can help mitigate integration issues.

WHY WE NEED YOU? GLAD YOU ASKED...
 

How would you like your code to be used by millions of people every single day? As a Backend-focused Developer on our team, you will drive the evolution of Canada's largest weather apps (The Weather Network and MeteoMedia) as well as Spain's top weather platform (El Tiempo) by continuing to build out the backend services to support dynamic application layouts, personalization, and core foundational services for our users.

We are currently optimizing and scaling our next-generation Weather applications-a single app binary that supports multiple brands and platforms. If you love solving complex, high-traffic technical challenges, want to champion clean architecture, and are excited about using modern AI development tools like GitHub Copilot to accelerate real-world features-we want you on our team. 

 Core Tech Stack: Go AWS GCP Node.js Docker Kubernetes Microservices React Native TypeScript Jenkins Fastlane GitHub Copilot 
Please note, we are only considering candidates who are eligible to work in Canada and can work in a Hybrid model at our Oakville location.
WHAT'S THE DAY TO DAY LIKE?

  • Architect & Innovate: Design, develop, and optimize high-performance features and foundational backend APIs using Go and Node.js to power dynamic application layouts and user personalization engines.

  • Scale for Millions: Continuously optimize code for lightning-fast performance, low latency, and heavy traffic spikes, leveraging AWS and on-premise based infrastructure, along with GCP, for backend service support.

  • Own the Lifecycle: Take ownership of end-to-end features, from writing clean, robust code to managing smooth deployments to the App Store and Google Play using Jenkins and Fastlane.

  • Modernize & Refactor: Keep our codebase pristine. You'll enjoy the balance of writing greenfield code from scratch and thoughtfully refactoring legacy systems, utilizing GitHub Copilot to speed up unit testing and boilerplates.

  • Collaborate & Build: Champion engineering best practices, participate in code reviews, and collaborate across a modern ecosystem utilizing AWS, Go, Node.js, and Kubernetes, as well as GCP.

Roles, responsibilities and duties may evolve and change over time.

WE ARE HOPING YOU HAVE:

  • Backend Expertise: 5+ years of experience in software development with a strong focus on backend infrastructure, specifically building the foundational services that drive dynamic layouts and personalization.

  • Cloud & Infrastructure: Experience working alongside cloud-based architectures, specifically AWS and GCP, as well as Docker, containerization, and microservices.

  • Testing Champion: You are familiar and experienced in Unit and Integration Testing to ensure our foundational APIs and data pipelines handle heavy traffic seamlessly.

  • Modern Tooling & AI: Comfortable integrating GitHub Copilot into your daily workflow to write efficient code and accelerate development.

  • Code Versatility: Equally comfortable refactoring legacy code and writing new code from scratch.

  • Full Stack Bonus (React Native): While this role is centered on backend services, practical experience with React Native and React (TypeScript proficiency is highly preferred), or proven experience deploying and managing mobile applications to the Play Store and App Store using automated CI/CD tools like Fastlane and Jenkins, is a highly valued asset.

YOU ARE MADE FOR THIS IF YOU...

  • Have a passion for creating highly performant mobile applications backed by powerful, scalable server-side architecture.

  • Are proactive, show initiative, and value quality in everything you do.

  • Aren't afraid to roll up your sleeves, try something new, and embrace modern AI-assisted engineering.
