Blockchain Developer Internship Jobs (NOW HIRING)

D3 is building the world's first purpose-built blockchain for DomainFi—bringing domain tokenization and DeFi primitives to a massive, rapidly growing $350B+ real-world asset class. We're revolutionizing how existing and future domain names are owned, traded, and leveraged in the digital economy.

Our elite team is stacked with industry veterans who have spent the last three decades shaping the internet, from pioneering domain name monetization to architecting key internet protocols to launching and running major TLDs like .xyz, .inc, .tv, and .link. With a proven track record of innovation and success, we're now redefining what's possible in the domain space.

We recently closed a $25M Series A led by Paradigm - one of the best investors in the industry. This will help fuel our mission to bring domains fully on-chain and unlock new financial possibilities for one of the internet's most valuable asset classes.

We're based in Los Angeles, with team members all over the world. We're looking for driven, talented builders to help build a trillion-dollar DomainFi economy. Join us!

This is a hybrid role in Los Angeles where you'll help build the next generation of user-facing web applications that connect traditional DNS with Web3 naming systems. As a Frontend Engineer (Entry Level), you'll work closely with senior engineers to design, develop, and optimize interfaces for our registrar, marketplace, and decentralized apps (dApps).

This is a great opportunity for recent graduates or junior engineers to gain hands-on experience in both Web2 and Web3 technologies while contributing to products that shape the future of internet naming.

• Work with product and design teams to turn requirements and wireframes into functional, user-friendly features.
• Build and maintain frontend components using React, Next.js, TypeScript, HTML, and CSS.
• Help develop decentralized applications (dApps) that integrate Web2 and Web3 APIs.
• Write clean, testable code and contribute to unit and integration testing.
• Fix bugs, improve performance, and optimize existing features with guidance from senior engineers.
• Learn and apply best practices in accessibility, SEO, and responsive design.
• Stay curious about new technologies and contribute ideas to improve user experience.

• Bachelor's degree in Computer Science, Software Engineering, or related field (or equivalent practical experience).
• 0–2 years of experience in frontend development (internships, projects, or open-source work all count).
• Familiarity with modern JavaScript frameworks (React preferred).
• Basic understanding of HTML, CSS, and responsive design.
• Exposure to Git version control and collaborative coding practices.
• Interest in blockchain/Web3 technologies is a plus, but not required—you'll learn on the job.
• Strong problem-solving skills, eagerness to learn, and ability to work in a team environment.

• Experience with CSS frameworks (e.g., Tailwind CSS, Bootstrap).
• Exposure to Web3 libraries like ethers.js or web3.js.
• Familiarity with mobile-first design and accessibility principles.
• Previous coursework, projects, or internships involving blockchain, NFTs, or dApps.
