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 are a fully remote company of around 200 team members from 30+ countries. We seek exceptional individuals around the world to do their best work and create a meaningful impact in their lives. We collaborate across time zones, are highly async, and document a lot. Twice a year we gather for company offsites in various locations. Check out our Careers page for more about working at Circle.

We’re hiring two senior full-stack engineers to join our CMS organization — one on CMS Core and one on CMS Builder. These teams are responsible for some of the most critical surfaces across Circle’s product. CMS Core owns core community features like discussions, the Home feed, search, and digests. CMS Builder supports our site builder for creating custom web experiences.

If you’re a product-minded engineer who enjoys tackling big, user-facing problems and shaping architecture with care, you’ll feel at home here.

• 5+ years of experience building and scaling SaaS products.

• Experience working on high-throughput, high-concurrency systems.
• Sound architectural judgment and a high bar for quality, balanced with pragmatism.
• Comfort working with and alongside AI tools in your development workflow.
