You could be the perfect fit to tackle the compelling challenges at Coinbase. Our work environment is dynamic and fast-paced, attracting individuals who aspire to define the future alongside exceptional colleagues who uphold the highest standards of excellence. While many roles at Coinbase offer remote flexibility, we place a high value on in-person collaboration throughout the year.

Create scalable user authentication patterns using OAuth, PKCE, Email/SNS OTP, and Passkeys. Follow conformant HTTP REST API definitions based on OpenAPI specifications. Write, publish, and update clear documentation, including quickstart guides and how-to manuals to encourage SDK adoption. Collaborate with various teams to integrate embedded wallets into internal products, ensuring cohesive design. Play a vital role in gathering user feedback and continuously enhancing APIs and SDKs. Promote the SDK within the crypto community to boost adoption. Develop end-to-end sample applications using the embedded wallets SDKs to showcase their advantages and evaluate developer experience. Troubleshoot and resolve complex fullstack issues, ensuring stability, reliability, and security. Participate in code reviews and provide constructive feedback to maintain high coding standards. What We Seek: A minimum of 5 years of fullstack development experience. Proficient in Typescript, React, and React Native, with strong capabilities in either Android, iOS, Unity, or Flutter. Experience with user authentication, Identity and Access Management systems, public key cryptography, and persistent storage methods on browsers and mobile devices. A reputation within open source communities, with proven success in boosting GitHub repository adoption. A deep understanding of distributed systems, microservices architecture, streaming systems, and event-driven architectures. Excellent communication skills with attention to detail and a passion for crafting clear, comprehensive developer documentation. Knowledge of crypto wallets, including key management, cryptography, and blockchain protocols (e.g., EVM, Solana). Familiarity with security best practices and experience in implementing secure coding standards in financial environments. Pay Transparency Notice:
