**Company Description** Shopify’s mission is to make commerce better for everyone. From building a new product feature for our commerce platform, to helping a merchant troubleshoot an issue over the phone, we want to empower our ecosystem through our work. Having a unified vision, a north star, is vitally important to ensure that we are all headed in the same direction. No matter the size or experience, we want to power every merchant’s experience. This is why we are all here. **Job Description** Shopify is on a fast-moving mission to make the best products for merchants, buyers, and partners around the globe — and engineers play a vital role in building that future.

Our teams deploy new code many times a day, and our production scale is massive. We’re talking over 1 million online stores, and hundreds of millions of requests a day. Thousands of entrepreneurs will see your work within seconds – a difficult but incredibly rewarding responsibility. Shopify is the largest Ruby on Rails application in the world and we're a big part of the Rails community. We’re constantly improving our codebase to make it even better. **Mobile Development (React Native, Android & iOS)** Our Mobile Engineers work along with designers and product managers to build and launch new features for our apps. You’ll work on large-scale apps that are ever-changing, enabling entrepreneurship for hundreds of thousands of entrepreneurs. Our Android engineers use Kotlin and our iOS engineers use Swift. Our teams are increasingly working with React Native so openness to cross-platform mobile development is a plus! **Front End Development** Our Front End Engineers (encompassing web and UX) work closely with software engineering teams, designers and product managers to not only build incredible merchant-facing products, but also engineer-facing tools. You’ll use modern technologies and frameworks like Typescript, React, GraphQL and Apollo, and the latest web standards in HTML, CSS, JavaScript, React, and Ruby on Rails, to develop large front-end web applications that scale and perform well on all devices.You’ll work across disciplines and are excited about building human-centered experiences. You’ll work closely with the teams that create compelling content, build awareness of Shopify, and communicate stories about Shopify's role in commerce to a global audience. Or, you might focus on creating thoughtful product interfaces for our users, shape our design language, and contribute to our shared component libraries in a maintainable and scalable way. **Infrastructure** Are you looking for an opportunity to work on planet-scale infrastructure? Do you want your work to impact thousands of developers and millions of customers? Do you genuinely enjoy tackling complex problems, and learning through experimentation? Shopify Production Engineering is all this and more. The Production Engineering team builds and maintains Shopify’s critical infrastructure through software and systems engineering. We make sure Shopify—the world’s fastest growing commerce platform—is able to scale massively while staying resilient for our 2000+ development team to build on and our 1 million merchants to depend on. Some of the technology that the team uses: Ruby, Rails, Go, Kubernetes, MySQL, Redis, Memcached, Docker, Distributed Systems, Google Cloud. Is some of this tech new to you? That’s OK!
