Senior Software Engineer, Backend (developer - X402)

Join Coinbase To Shape The Future Of Internet-Native Payments

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. At Coinbase, we are building the future of internet-native payments. The x402 protocol is at the core of this mission, an open, internet-scale standard designed to make global payments as seamless as sending an email. As part of the Coinbase x402 team, you'll help define and evolve this protocol alongside the broader open-source community, while also building the developer tools, SDKs, and payment infrastructure that bring x402 to life. This is a high-impact role at the intersection of crypto, payments, agentic commerce, and open standards, shaping how money moves on the internet for the next decade.

What you'll be doing:

• Defining the x402 protocol standard for the internet-native payment protocol
• Building and maintaining x402 related products such as the x402 SDK, Payment MCP, Payment Facilitators, and onchain payment protocols
• Collaborating with open-source contributors to evolve the standard through GitHub discussions, issues, and PR reviews

What we look for in you:

• 6+ years of experience in software development with a strong focus on backend development working closely with frontend engineers; crypto experience is a plus
• Strong experience in building scalable and secure software and SDKs
• Proficiency with Golang, Typescript, and Python
• Knowledge of Web3 technologies, stablecoins, smart contracts, and wallets

Pay Transparency Notice: Depending on your work location, the target annual salary for this position can range as detailed below. Full time offers from Coinbase also include bonus eligibility + equity eligibility + benefits (including medical, dental, vision and 401(k)). Pay Range: $186,065—$218,900 USD
