About the role

We’re looking for a Senior Full-Stack Engineer to join our Growth Engineering team. This team drives some of Circle’s most critical initiatives: billing and plan infrastructure, trial and onboarding flows, A/B experimentation, and now — expanding into analytics and member experiences. With millions of members engaging across Circle communities, the work you do here will have an outsized impact. If you thrive in a data-driven environment, love refining experiences to feel seamless and intuitive, and want to help scale the systems that power growth at Circle, this role is for you.

What you’ll be doing

• Shipping often and with care, balancing speed with thoughtful, quality work.
• Owning end-to-end projects — from concept and development to rollout and measurable results.
• Partnering with engineers, designers and product leaders to craft member experiences that feel beautiful, simple, and premium.
• Scaling our billing infrastructure to support both self-service and sales-led use cases.
• Designing and implementing A/B tests to validate changes that boost user acquisition, retention, and expansion.
• Building world-class analytics that empower community owners with deep insights to understand and grow their communities.

Bonus points

• Experience working in a growth-oriented engineering role.
