About the Team: We're hiring a Senior Software Engineer to join the Identity team within Platform and help build the systems that power every user's relationship with Coinbase. The Identity team owns everything related to user identity — login, passwords, MFA, security questions, and session management — and the Accounts pod is driving the evolution from single-user models to a unified, multi-user and organization-aware platform. You'll architect and deliver the APIs, data models, and backend services that enable seamless, secure, multi-entity account management at Coinbase scale — future-proofing our growth across Consumer, Institutional, and new verticals. What you’ll be doing: Own the design and reliability of business-critical Tier-0/Tier-1 backend systems serving millions of customers, ensuring security, observability, and operational excellence. Lead the evolution from fragmented user/org models to a unified Account abstraction — defining APIs, data models, and best practices adopted across every Coinbase product. Architect and deliver platform services enabling seamless, secure, multi-entity account and identity management, making it fast and easy to add new entity types (e.g., org, partner, vertical). Champion technical excellence by driving code and design reviews, setting engineering standards, and shaping the team's technical culture. Mentor and level-up engineers across the team, creating a multiplier effect on developer velocity and platform reliability. Collaborate cross-functionally with Product, Infrastructure, SRE, and Compliance teams to deliver secure, observable, and extensible solutions. Proactively identify opportunities for platformization, refactor legacy components, improve performance, and harden security and compliance posture. What we look for in you: 5+ years of experience in software engineering, with a focus on backend systems. Proven experience designing, building, scaling, and maintaining production services in a service-oriented architecture. Track record of writing high-quality, well-tested code that meets customer needs and withstands production demands. Strong collaboration skills with the ability to work cross-functionally across product, infrastructure, and compliance teams. Passion for 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 at a company during rapid growth (startup to mid-size scale). Familiarity with blockchain technologies (Bitcoin, Ethereum, etc.) and crypto-forward experience such as interacting with Ethereum addresses, ENS, dApps, or blockchain-based services. Experience decomposing a large monolith into microservices. Proficiency with Golang, Ruby, Docker, Sinatra, Rails, Postgres, MongoDB, or Redshift. Background building financial, high-reliability, or security systems. Pay Transparency Notice: Base salary varies by location (see range below).
