Senior Software Engineer, Backend - Payments Platform

We're hiring a Senior Software Engineer to join the Payments team within the Platform organization. The Payments team builds the infrastructure, workflows, and APIs that power fiat on- and off-ramps for millions of consumers and institutional customers globally, across payment rails, partner integrations, and funds-flow systems. We are turning that stack into an API-driven platform, a Stripe-like product for Coinbase's own Retail, Institutional, and Developer teams, so a new payment method or rail can go live in a fraction of the time it takes today. Our north star is payment success rate: the share of attempted payments that move safely and reliably, end to end. You'll design and build scalable backend systems that process high-volume payment traffic, working closely with Product, Engineering, and cross-functional partners to expand Coinbase's payment capabilities into new markets and corridors.

What you'll do:

• Design and build scalable, fault-tolerant backend services for payment processing using Go, ensuring high reliability and correctness for financial transactions at scale
• Own end-to-end delivery of payment features, from technical design through production deployment, monitoring, and iteration
• Build the platform primitives, extension points, and self-serve APIs that let other Coinbase teams add new payment methods and rails without deep changes to the core services
• Partner with engineers, product managers, and senior leadership to translate product vision and business requirements into technical plans each quarter
• Drive improvements to system reliability, observability, and performance across payment services, proactively identifying and resolving bottlenecks
• Contribute to engineering quality through thoughtful code reviews, design discussions, and advocacy for best practices in service-oriented architecture

Required Skills and Experience:

• 5+ years of experience in backend software engineering, with hands-on experience building and maintaining production services in a service-oriented or microservices architecture
• Proficiency in Go or similar backend languages, with experience designing scalable, low-latency APIs and distributed systems
• Track record of owning features end-to-end, from design through deployment and production support, in a fast-moving environment
• Experience with financial systems, payments infrastructure, or high-volume transactional systems that require precision and auditability
• Utilizes generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality
