What the job involves

• We’re looking for a seasoned full-stack engineer to join Circle’s Payments team and help expand the monetization engine that powers thousands of community-based businesses
• You’ll work across both infrastructure and product surfaces — from integrating payment providers and scaling checkout flows, to building high-converting paywalls, upsells, and subscription tools
• A core focus of this role is building and evolving Circle’s billing and invoicing engine, including managing subscription plans, schedules, invoicing, proration, and billing workflows
• We’re looking for someone who has lived through building or operating these systems and understands their technical and business complexity
• This is a hands-on role with broad scope
• You’ll own features end-to-end: system design, implementation across the stack, payment gateway integrations, and close collaboration with product and design to ship reliable, polished experiences
• If you’re excited about scaling critical systems, crafting seamless checkout and monetization flows, and empowering creators to grow globally, this role is for you
• Work autonomously across our Ruby on Rails backend and React front-end to ship high-quality features quickly and safely
• Lead complex projects end-to-end, driving architectural and product decisions
• Design and scale our subscription billing and invoicing platform, including multiple pricing structures, plan changes, proration, invoicing, and full subscription lifecycle events
• Anticipate and design for common billing edge cases such as partial periods, legacy pricing, tax/VAT integration, and failed payments
• 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 UX
• Collaborate with leadership, product, and design from early exploration through launch
• Continuously improve performance, developer experience, and code quality
• Balance iteration speed with technical and UX excellence, shipping behind feature flags when needed
