Senior Full-Stack Software Engineer, Discover - Circle

About Us

Circle is building the world’s leading AI-powered, all-in-one platform for digital businesses. We make it possible for creators, coaches, educators, and businesses to bring together their audience with engaging discussions, live streams, events, chat, courses, and payments — all in one place, all under their own brand.

We’re proud to be a fully remote company of around 270 (and growing!) team members from 30+ countries around the world. We collaborate across time zones, are highly async, and like to document a lot. Twice a year, we bring the whole company together in beautiful places around the world for our company offsites.

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.

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 and with our designers to create a world-class user experience.
• Foster a bias for action, prioritizing speed of iteration without compromising on code quality 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 (high degree of frontend proficiency required).
• A desire to work in an environment which values speed of iteration, individual autonomy, and personal accountability.
• Comfortable in a fast-paced environment with ambiguity.
• Great communication skills in written and spoken English (CEFR Level C2 / ILR Level 5).
• Experience working on a fully distributed remote team.
• Strong alignment with Circle's company values.

Bonus Points

• Previous experience working with creator-platforms, social content and video feeds, or marketplaces.
• Experience with A/B testing and experimentation in 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.

Compensation & Benefits

Circle offers U.S.-benchmarked compensation globally, equity with ongoing refresh grants, and 35 days of paid time off each year. We also host biannual company retreats in incredible destinations around the world.
