Web3 & Crypto Jobs in California

About D3:

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!

Position Overview

This is a hybrid role in San Francisco or Los Angeles that offers extraordinary creative freedom and ownership in revolutionizing how domains become financialized assets. As Tech Lead, you'll have autonomy to design novel tokenization standards, build sophisticated financial primitives, and shape the technical foundation of DomainFi. You'll tackle complex technical challenges like creating composable domain assets, implementing secure cross-chain ownership systems, and developing infrastructure to support domain-backed lending and fractionalization.

Working directly with successful founders who've built and sold multiple domain companies, you'll have the opportunity to learn from industry veterans while building and scaling your own high-performing engineering team. Your work will directly influence how millions of domains are tokenized, traded, and utilized across the Web3 ecosystem. This is a unique opportunity to transform a massive existing industry by creating entirely new markets and use cases for digital asset ownership.
