You will be part of our top-notch team of Barcelona beach-based developers (ocean views from your workspace 🏖️). You'll help build the user interface of our award-winning FX platform working shoulder to shoulder with the UX, Product, and Tech teams.

We are seeking a developer who is comfortable working with frameworks like Angular, React, Vue, or similar and is excited to explore the world of Ember. No prior Ember experience is necessary, we'll provide you with all the resources and support you need to master it, eventually enabling you to teach us a thing or two!

This role extends far beyond just working with Ember. We are actively developing a platform-agnostic component library using Stencil.js and web components. This library is designed to provide reusable components that seamlessly integrate across an expanding UI ecosystem, which includes frameworks like Ruby on Rails (RoR), Phoenix, and others we plan to adopt. Our backend is primarily built using Ruby on Rails, with additional services developed in Elixir (Phoenix) to handle specific functionalities.

At Kantox, we value a self-driven mindset and a strong desire to learn and grow. Asking questions and embracing mistakes as learning opportunities are essential traits for thriving in our culture. With a flat management structure, we place great trust in the expertise and contributions of every team member. You'll collaborate with a highly motivated, diverse, and multidisciplinary team that sees software development as the ultimate team sport.
