We seek exceptional individuals around the world, set them up to do the best work of their lives, and in turn, create a meaningful impact in their own lives.

About the role

We’re looking for a seasoned full-stack engineer to help evolve and expand Circle Discover - Circle’s curated marketplace for finding and buying digital experiences (communities, courses, memberships, and eventually more).

As a part of the Discover team, you’ll build the product surface area that helps members explore, discover, and join digital experiences - including algorithmic recommendations, rich listings, engaging content feeds and seamless purchasing flows. We’re looking for someone who’s excited to shape how people find value in community and cares deeply about creating intuitive, performant, and elegant user experiences at scale.

What you'll be doing
  • - Build polished, high-converting purchasing experiences that help members discover digital experiences and businesses sell digital memberships, courses, and content at scale.

  • Run A/B tests and experiments to validate changes that boost user acquisition, retention, and conversion behavior.

  • Implement and improve features in the Discover Next.js frontend application together with API endpoints in our Rails backend.

  • Work on data pipelines and services driving search and recommendations.

  • Proactively improve the quality of our codebase, processes and architecture.

  • Work closely with Circle's leaders throughout the feature design process.

  • Work closely with our designers to create a world-class user experience.

  • Foster a bias for action, prioritizing speed of iteration without compromising on the quality of code or user experience.

What you'll need to be successful
  • 5+ years experience working as a full-stack engineer on complex web applications with significant scale (100k+ rpm, 100GB+ databases).

  • Strong proficiency in Next.js, ReactJS, TypeScript, Tailwind, Ruby on Rails and MySQL/Postgresql. Familiarity with both frontend and backend is necessary, but a high degree of proficiency in frontend is required.

  • A desire to work in an environment which values speed of iteration and individual autonomy, while also embracing personal accountability and the ability to collaborate effectively as part of a dynamic team.

  • Comfortable in a fast-paced environment with a certain level of ambiguity, especially when learning and picking up new technologies when projects require it.

  • Great communication skills both in writing and verbal/oral (English).

  • Experience working on a fully distributed remote team.

  • Strong alignment with our values, find our values on our career page if you haven’t read up on them yet.

  • You are proficient in English (spoken, written, and reading) at a CEFR Level C2 / ILR Level 5.

Bonus points
  • Previous experience working with creator-platforms, social content and video feeds, or marketplaces.

  • Experience with A/B testing and experimentation to optimize user experience, performance and conversion within consumer-facing applications.

  • Previous exposure to search, recommendation and personalization at scale.

  • Production experience with Next.js and hybrid React/Next.js systems for high-traffic applications
