at Coinbase Careers Page

United States (Remote)

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.

The CDP APIs are the easiest way for developers to get started with building crypto applications. Conceived by Coinbase CEO Brian Armstrong, these APIs enable those with no prior knowledge of crypto to begin using crypto in under 30 seconds. The CDP APIs are positioned to bring the next million developers onchain, enabling trading, lending, payments, and more.

The CDP API team owns both server-side APIs and client-side libraries across different languages. The team seeks a backend engineer who is passionate about all aspects of excellent developer experiences: authoring clear and informative documentation, building compelling onboarding flows, interacting directly with customers to incorporate feedback, architecting delightfully simple APIs, etc. The engineer must be comfortable operating in both frontend and backend codebases, fluent across a variety of programming languages, and demonstrate both high code velocity and quality simultaneously. The CDP API team consists of some of the most prolific and tenured software engineers at Coinbase, and is excited to ship a game-changing set of APIs and SDKs at breakneck speed.

What you’ll be doing:

Design, develop, and maintain ergonomic, open-source SDKs for embedded wallets using Typescript, React, React Native, Android, iOS, Unity, and Flutter
Build scalable interaction patterns involving end user authentication using OAuth, PKCE, Email/SNS OTP, and Passkeys
Interface with and conformant HTTP REST API definitions using OpenAPI specifications
Author, publish, and maintain clear and concise documentation, including quickstart and how-to guides, to increase adoption of the SDKs
Work closely with many different teams at Coinbase to integrate embedded wallets into internal products, ensuring consistency of concepts, style, and design
Work directly with customers to collect their feedback and iteratively improve the APIs and SDKs
Evangelize the SDK in the crypto community to gain greater adoption
Build compelling sample applications end-to-end using the embedded wallets SDKs to demonstrate their value and pressure-test the developer experience
Troubleshoot and debug complex fullstack issues, ensuring stability, reliability, and security
Participate in code reviews and provide constructive feedback to maintain high code quality standards

What we look for in you:

5+ years of experience in fullstack development
Fluency in Typescript, React, and React Native, and strong experience in at least one of the following: Android, iOS, Unity, Flutter
Experience with user authentication, Identity and Access Management systems, public key cryptography, browser and mobile persistent storage mechanisms
Established reputation in open source communities, with operational knowledge of how to grow adoption of GitHub repos
Strong understanding of distributed systems, microservices architecture, streaming-based systems, and event-driven architectures
Excellent verbal and written communication skills, with an eye for detail and a passion for clear, comprehensive developer documentation
Fluency with crypto wallets, including key management, cryptography, and blockchain protocols (e.g. EVM, Solana)
Understanding of security best practices and experience with implementing secure coding practices for financial systems
