Stack App information

What is a stack app?

Stack Apps are applications, scripts, and tools built using the Stack Exchange API. They are designed to enhance the user experience on Stack Exchange sites by providing additional features, integrations, or utilities. Developers create Stack Apps to automate tasks, provide analytics, or interact with Stack Exchange data in creative ways. The Stack Apps platform also serves as a community for sharing and discussing these tools.

What are the main responsibilities of a stack app developer within a typical software development team?

A Stack App Developer is responsible for building, maintaining, and optimizing applications across the full technology stack—both front-end and back-end. In a typical team, they collaborate closely with designers, product managers, and other engineers to deliver functional, user-friendly features. Daily tasks may include coding, code reviews, debugging, and participating in agile ceremonies. This role often involves problem-solving and adapting to new technologies as project needs evolve, making strong communication and teamwork skills essential.

What are the key skills and qualifications needed to thrive as a stack application developer, and why are they important?

To thrive as a Stack Application Developer, you need strong proficiency in programming languages (such as JavaScript, Python, or Java), knowledge of front-end and back-end frameworks, and typically a degree in computer science or related field. Experience with development tools like Git, databases (SQL or NoSQL), and cloud platforms is commonly required, along with familiarity with CI/CD pipelines. Excellent problem-solving skills, communication, and the ability to work collaboratively in agile environments set top performers apart. These skills are crucial for building robust, scalable applications, maintaining code quality, and delivering efficient solutions in dynamic development teams.

Read about us here! (spoiler alert... we are the home of The Weather Network )
 
Proud to share that we ranked #5 Most Admired Company in Canada in Leger's 2026 Reputation Study, among 334 organizations
 
 
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.

Fair and Authentic Interview Experience
We welcome candidates using AI tools to prepare for interviews or to learn more about Pelmorex. During the interviews themselves, we expect responses to come from your own experience and thinking.
