An IDEAS (Inclusion, Diversity, Equity, Awareness, Solidarity) team

Weather is inclusive, we will be too. Our IDEAS team is committed to making this happen!

HAVE WE GOT YOUR ATTENTION? WANT TO LEARN MORE?

Read about ushere!(spoiler alert… we are the home of The Weather Network )

Proud to share that we ranked #5 Most Admired Company in Canada inLeger's 2026 Reputation Study, among 334 organizations

WHY WE NEED YOU? GLAD YOU ASKED...

We are seeking a proactive, highly motivated React to build engaging, interactive, and community-driven experiences across The Weather Network (TWN) and MétéoMédia (MM) Mobile Apps (iOS & Android via webviews) and Digital platforms (Desktop and Mobile Web).

As a driven self-starter, you will work closely with Product Managers who bring the requirements and product vision, and you will partner directly with a Tech Lead to learn the ins and outs of our infrastructure, technical requirements, and architecture. You will operate with a flexible mindset—experimenting with new technologies and UX approaches in some cases, and engineering robust, scalable solutions for production in others.

Whether evaluating third-party libraries, integrating SaaS platforms, or building custom code, you will help design and execute solutions for live chat modules, logged-in/premium user experiences, and interactive community elements (comments, likes, shares, stories). Your work will directly transform our mobile and digital applications into a highly interactive, community-driven ecosystem.

Please note, that this is a 12 month Contract role and 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?

• Technical Solution Architecture & Prototyping: Partner with Product Managers and your Tech Lead to turn functional requirements into smart technical solutions. Evaluate whether to leverage third-party libraries, integrate SaaS solutions, or build custom features depending on project needs.

• Experimentation & Production Building: Work comfortably across the entire development spectrum — rapidly prototyping and testing experimental technologies/UX approaches in some scenarios, while building clean, maintainable, production-ready code for high-traffic environments in others.

• Tech Lead & Cross-Functional Partnership: Collaborate closely with a Tech Lead to master our technical architecture and infrastructure guidelines.

• React Development: Conceptualize, design, develop, and implement high-quality, scalable features for web platforms using React and React.

• Community Building: Build and integrate real-time social functionalities across mobile and web platforms, including comment threads, like/share actions, user stories, and live chat modules.

• User Journeys: Develop and optimize logged-in and premium user experiences across mobile app and digital touchpoints, ensuring seamless state management and personalized interfaces.

• Performance & Mobile Optimization: Maintain UI/UX quality, ensuring top-tier responsiveness, accessibility, battery efficiency, and performance across mobile devices and web platforms. Continually optimize code for smooth animations and low latency.

• Testing & Continuous Delivery: Build solutions with a Test-Driven Development (TDD) mindset. Write unit tests, manage app release pipelines (CI/CD), and support QA testing when required.

WE ARE HOPING YOU HAVE:

• Core Stack Focus (React): Proficiency and hands-on experience building, launching, and maintaining web platforms using React and React.

• Pragmatic Problem-Solving & Technical Range: Proven ability to translate product requirements into sound technical solutions. Comfortable working in both experimental settings (rapid prototyping, evaluating third-party SDKs, trying new UX patterns) and structured production releases.

• Proactive Self-Starter Mindset: Highly motivated and resourceful. Demonstrated ability to take initiative, ask the right questions, partner effectively with technical leaders, and own feature delivery end-to-end.

• Experience: Minimum 3 to 4 years of related job experience specializing in front-end and mobile app development for high-traffic environments

• Education: University degree in Computer Science, College diploma in Computer Programming, Information Technologies, or a related discipline.

• Web & Mobile Technologies: Expert-level understanding of modern JavaScript / TypeScript (ES6+), HTML5, and CSS3/SASS.

• Interactive & Real-Time Features: Experience building real-time interactive mobile and web features (e.g., utilizing WebSockets or SaaS tools for live chat) and social engagement modules.

• API & Third-Party Integration: Experience designing UI/mobile interactions that consume RESTful APIs, GraphQL, third-party SDKs, and SaaS services.

• State Management: Solid experience with state management libraries in the React ecosystem (e.g., Redux, Context API, Zustand).

• Responsive Design: Deep understanding of mobile-first design principles, and cross-device compatibility.

YOU ARE MADE FOR THIS IF YOU...

• Balance Experimentation with Engineering Rigor: You enjoy testing new tech and UX concepts just as much as writing clean, battle-tested code for production environments.

• Are a Collaborative Self-Starter: You take initiative and bring ideas to the table, but you also value learning from a Tech Lead and aligning with cross-functional partners.

• Are a Pragmatic Solution Finder: You know when to leverage existing SaaS tools and open-source libraries versus when to build custom solutions from scratch.

• Are Passionate About Mobile & Community Tech: You love mobile app ecosystems and has an intrinsic understanding of what drives digital community engagement and user retention.

• Have an Eye for UI/UX: You possess a strong eye for design, basic knowledge of UI/UX principles, and familiarity with tools like Figma, Adobe Illustrator, or Photoshop.

• Love Animation & Micro-interactions: Experience with mobile and web animation libraries (e.g., Framer Motion, GSAP) to build engaging "Stories" or polished micro-interactions.

• Master Mobile Deployment & Agile Workflows: Proficient with Git (GitHub, Bitbucket), mobile build/deployment pipelines (Fastlane, App Store Connect, Google Play Console), and Agile/Scrum methodologies.
