Circle
Senior Full-Stack Engineer, Payments
Circle is building the world's leading all-in-one platform for online communities. 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 200 team members from 30+ countries around the world. We collaborate across time zones, are highly async, and like to document a lot.
About The Role We're looking for a seasoned full-stack engineer to join Circle's Payments team and help us expand the monetization engine that powers thousands of community-based businesses. You'll work across both infrastructure and product surfaces—integrating new payment providers and scaling checkout flows, and building high-converting paywalls, upsells, and subscription tools.
What you'll be doing
Work autonomously across our Ruby on Rails backend and React front-end to deliver high-quality features quickly and safely.
Lead complex projects end-to-end, driving architectural and product decisions.
Build and evolve monetization features like paywalls, upsells, affiliate tools, and subscription settings.
Integrate and scale payment solutions (e.g., Stripe, PayPal, in-app payments) to support global audiences, multiple currencies, and diverse business models.
Optimize checkout and paywall experiences for reliability, conversion, and seamless UX.
Collaborate with leadership, product, and design from early exploration to launch.
Continuously improve performance, developer experience, and code quality.
Balance iteration speed with technical and UX excellence, shipping behind feature flags where needed.
What you'll need to be successful
Strong alignment with our values.
Proficiency in English at CEFR Level C2 / ILR Level 5.
5+ years of experience building and maintaining complex full-stack web applications.
Advanced proficiency in Ruby on Rails, MySQL/PostgreSQL, ReactJS, TypeScript, CSS/SCSS, and TailwindCSS.
Hands-on experience integrating and maintaining payments in production environments.
Strong understanding of checkout flows, subscription lifecycles, and monetization mechanics.
Product mindset: curiosity about the "why" and focus on user outcomes.
Comfort operating with autonomy in a fast-paced, remote-first environment.
Adaptability and willingness to shift focus as business needs evolve.
Experience working on a fully distributed team.
Bonus points
Experience with advanced Stripe features (Connected Accounts, Subscriptions, Invoicing, Subscription Schedules).
Background working with community platforms, creator tools, or other user-first SaaS products.
Track record of building polished, pixel-perfect interfaces with attention to detail.
