Senior Full-Stack Engineer, Payments Platform

About Us

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 180 (and growing!) team members from 30+ countries around the world. 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. We don't track hours, but we do manage for high expectations very closely. 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. So far, we’ve hosted offsites in Turkey, Portugal, Mexico, Thailand, Colombia, Italy, Ireland, and more, with still more to come!

About the role

We’re looking for a seasoned full-stack engineer to help evolve and expand Circle’s payments infrastructure. As part of our Payments Platform team, you’ll play a key role in building, maintaining, and scaling the critical systems that power how our communities monetize on Circle.

This role focuses on the infrastructure behind our payment experiences — from integrating new payment providers to ensuring our checkout flows are reliable, secure, and seamless. You’ll be involved in all stages of the development lifecycle, from technical design to deployment and ongoing support.

As a senior engineer, you'll break down large projects into actionable tasks, lead development efforts, review PRs, and ensure high-quality releases behind feature flags. Your responsibilities will also include bug-fixing and continuous improvement of the codebase. This role requires high technical proficiency and a strong understanding of software development best practices.

If you're excited about scaling critical systems, integrating checkout flows with multiple payment providers, and collaborating across teams, this could be the perfect fit!

What you'll be doing

• Work autonomously across our Ruby on Rails backend and React front-end.
• Lead complex projects end-to-end, making thoughtful decisions around architecture, design, and product.
• Integrate and scale payment solutions like Stripe, PayPal, and native in-app payment providers.
• Scale our checkout experiences — ensuring they are seamless, reliable, and optimized.
• Build and improve critical monetization features with a strong product focus.
• Collaborate closely with Circle's leadership and product teams during feature design.
• Partner with designers to deliver seamless, intuitive user experiences.
• Move fast with purpose — balancing iteration speed with technical and UX excellence.

• Strong proficiency in Ruby on Rails, MySQL/PostgreSQL, ReactJS, TypeScript, CSS/SCSS, and TailwindCSS.
• Deep experience integrating and maintaining payment systems (e.g. Stripe, PayPal) — ideally with multiple providers in a production environment.
• A strong understanding of checkout flows, payment processing, subscriptions lifecycle, and monetization architecture.
• Motivation to understand the business, our users, their requirements, and to deliver results.
• A desire to work in an environment that values speed, autonomy, and accountability.
• Comfortable in a fast-paced environment with a certain level of ambiguity.
