About the Role
We’re hiring a Senior Full-Stack Engineer to join the CMS Platform team. CMS Platform owns the systems for composing and presenting content across Circle, including our Page Builder experience and forms, plus laying the groundwork for future AI-first interfaces.
You’ll work across product-facing experiences (editing, previewing, publishing, layout, components) and the backend systems that make them possible (content models, rendering/publishing pipelines, permissions, and performance). If you enjoy turning ambitious product ideas into polished, scalable systems, this role is for you.
What you'll be doing
Build and ship Page Builder features that directly impact how customers design and publish their sites.
Work across the stack using React & TypeScript (frontend) and Ruby on Rails (backend).
Partner closely with product/design to translate specs into high-quality, user-friendly experiences.
Improve the architecture of the builder/editor and publishing pipeline for reliability, extensibility, and performance.
Own projects end-to-end—from technical design through implementation, testing, rollout, and iteration.
Review PRs thoughtfully and contribute to a culture of quality and continuous improvement.
Work async-first and communicate clearly and proactively.
What you'll need to be successful
Strong alignment with our values. Find our values on our career page if you haven’t read up on them yet.
5+ years of experience building and scaling SaaS products.
Deep experience with Ruby on Rails and strong proficiency with React & TypeScript.
A product mindset—you care about the “why,” sweat UX details, and iterate based on customer needs.
Experience building complex, stateful UI (editors, builders, or design tools) and/or the systems behind them.
Solid architectural judgment and a high bar for quality, balanced with pragmatism.
Comfort working with and alongside AI tools in your development workflow.
Excellent async communication and collaboration skills.
Exceptional written and verbal communication skills in English (CEFR C2 or equivalent), as most collaboration at Circle happens asynchronously.
Bonus points
Experience working on site builders, page editors, or CMS platforms.
Experience with rich text/content editing, drag-and-drop interactions, component systems, or design tooling.
Familiarity with web performance, caching strategies, and scaling high-traffic rendering/publishing systems.
Prior experience at an early-stage or growth-stage startup.
Contributions to open-source projects or developer communities.
Compensation & benefits
Circle offers U.S.-benchmarked compensation globally, equity in the company with ongoing refresh grants, and 35 days of paid time off each year.
We’re a remote-only team that comes together twice a year for company retreats in incredible destinations around the world. Alongside incredible flexibility and autonomy, we offer a benefits package that supports health, wellbeing, and professional growth. Learn more in our Candidate Hub.
