Web3 Senior Engineer

Career Renew is recruiting for one of its clients a Web3 Senior Engineer - this is a fully remote role, but candidates need to be based in CET +/-3 timezones.

We are at the heart of the Decentralized Science (DeSci) movement where biotech and blockchain meet to democratize scientific research, earning recognition and support from key figures in the web3 world, including Vitalik Buterin, Balaji, and Juan Benet. We're known for creating VitaDAO, the first and largest biotech DAO with more than $4m in funding deployed, bio.xyz, a vital hub supporting and building biotech DAOs, the IP-NFT, a protocol bringing rights to IP and R&D data on-chain, and IPTs, ERC-20 tokens minted from IP-NFTs to allow token holders to construct and cultivate valuable IP. We’ve also recently launched Catalyst, a platform to launch, discover, and fund the best projects in DeSci.

Over the past 24 months, we have raised $20+ million to build the future of decentralized biotech. Join us and contribute to a future where scientific discovery is driven by web3.

We are looking for an experienced engineer with proven web3 builder experience to join our team. You will design, develop, and implement applications that run on blockchains and decentralized infrastructure. As a fundamental part of a cross-functional team you'll deliver cutting-edge contracts and services that fuel and define the growing DeSci ecosystem.
