About Swanky

We’re Swanky, a fast-growing global ecommerce agency. We design, build and grow Shopify Plus stores that convert, and we’re expanding our expertise into mobile-first ecommerce experiences.


If you’ve built mobile apps that engage customers, integrated with Shopify APIs, and want to be part of a team that creates seamless shopping journeys across devices, this could be just the role for you.


About the Role

This is a Mobile App Developer (Flutter + Shopify) role. Applicants are expected to have strong commercial experience building cross-platform mobile applications in Flutter, combined with solid experience delivering Shopify storefronts, apps or integrations.


You’ll work with our developers, designers, analysts and project managers to create connected, mobile-first ecommerce solutions. From architecting new apps to integrating Shopify APIs into mobile experiences, you’ll be the team’s go-to person for mobile innovation and problem solving.


Daily tasks could include:


  • Building and maintaining cross-platform mobile apps in Flutter and Dart.
  • Integrating Shopify APIs into mobile apps (products, carts, checkout, customer accounts).
  • Extending Shopify with custom apps, checkout extensions or headless integrations.
  • Designing scalable mobile architectures that support ecommerce performance.
  • Helping scope technical requirements with project managers and clients.
  • Mentoring junior developers and contributing to our development culture.

  • Collaborate with the Director of Technology on product and solution design.
  • Conduct code reviews and ensure coding standards are upheld.
  • Mentor peers and knowledge-share to uplift the team’s mobile expertise.


About You

You’re a mobile-first engineer who loves creating high-performing user experiences. You’re also comfortable navigating Shopify’s ecosystem and can bridge mobile apps with ecommerce backends. You thrive in a fast-paced, collaborative environment where no two projects are the same.


Role Requirements

  • Practical experience working with Shopify storefronts, apps, or Plus builds.
  • Strong understanding of mobile app architecture, state management, and performance optimisation.
  • Experience integrating third-party APIs and SDKs.
  • Familiarity with app deployment (App Store, Google Play).
  • Good knowledge of modern web development (HTML, CSS, JavaScript).
  • Solid understanding of Git and version control.
  • Strong communication and collaboration skills.


Advantageous

  • Experience with React Native.
  • Experience with headless ecommerce.
  • Experience with Firebase or Supabase (mobile backends).
  • Experience with TypeScript.
  • Previous lead developer experience on mobile projects.
  • Knowledge of CI/CD for mobile apps.
  • Familiarity with Agile/Scrum workflows.
  • Deep understanding of performance, animations or accessibility in mobile.
