Ready to be pushed beyond what you think you’re capable of? At Coinbase, our mission is to increase economic freedom in the world. It’s a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform — and with it, the future global financial system. To achieve our mission, we’re seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system. We want someone who is eager to leave their mark on the world, who relishes the pressure and privilege of working with high caliber colleagues, and who actively seeks feedback to keep leveling up. We want someone who will run towards, not away from, solving the company’s hardest problems. Our work culture is intense and isn’t for everyone. But if you want to build the future alongside others who excel in their disciplines and expect the same from you, there’s no better place to be. While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported. We are looking for a Senior Software Engineer to join the Payment Rails team within Coinbase's Platform organization. Payment Rails is the foundational infrastructure that powers how money moves at Coinbase—processing fiat deposits, withdrawals, and transfers across payment methods, gateways, and banking integrations at scale. You'll design and build the low-latency, high-throughput backend services that ensure every transaction is fast, secure, and reliable, directly enabling millions of customers to move value seamlessly across the Coinbase ecosystem and beyond. What you’ll be doing (ie. job duties): - Design and build scalable payment systems that process millions of transactions daily—developing APIs, services, and integrations that power deposits, withdrawals, and fund transfers across multiple payment methods and rails. - Own backend services end-to-end from architecture through production—writing high-quality, well-tested code and operating services that must be correct, auditable, and reliable in a real-time financial environment. - Partner cross-functionally with Product, Design, Compliance, and Finance to translate complex payment requirements into robust, scalable technical solutions that balance speed, safety, and regulatory compliance. - Drive technical vision and execution by working with engineers, product managers, and senior leadership to shape the long-term roadmap for Payment Rails—identifying opportunities to improve reliability, reduce latency, and scale our systems. - Integrate with internal and external partners including banking systems, payment processors, and teams across Coinbase (e.g., FinHub, Ledger, Risk) to ensure seamless money movement across the platform. - Contribute to engineering excellence by mentoring teammates, participating in design reviews, and helping build a strong, inclusive, and high-performing engineering culture. What we look for in you (ie. job requirements): - 5+ years of experience in backend software engineering, with demonstrated experience building high-volume, low-latency distributed systems. - Strong coding skills in Go (preferred) or similar languages, with solid understanding of relational databases, transactions, and data consistency. - Experience designing and operating production services at scale—including monitoring, alerting, incident response, and performance optimization. - Deep understanding of distributed systems, APIs, and system design principles—you can decompose complex problems into well-structured, service-oriented architectures. - Proven ability to collaborate across teams and functions, driving alignment with both technical and non-technical stakeholders. - You're passionate about building an open financial system that brings the world together. - Demonstrates the ability to responsibly use generative AI tools and copilots (e.g., LibreChat, Gemini, Glean) in daily workflows, continuously learn as tools evolve, and apply human-in-the-loop practices to deliver business-ready outputs and drive measurable improvements in efficiency, cost, and quality. Nice to haves: - Experience with payment systems, banking integrations, or financial infrastructure (e.g., ACH, SWIFT, SEPA, card networks, payment processors). - Experience with blockchain technology, stablecoins, or crypto payment flows. - You've gone through rapid growth at a company (from startup to mid-size) and understand the challenges of scaling systems and teams. - Crypto-forward experience, including familiarity with onchain activity such as interacting with Ethereum addresses, using ENS, and engaging with dApps or blockchain-based services.
