Rust jobs in crypto and blockchain companies

Conduit – The Onchain Compute CompanyAt Conduit, we're building the rollup-native cloud platform that will scale Ethereum.Crypto builders have been held back by a lack of onchain compute — without the ability to process a high volume of transactions quickly and cheaply, onchain apps and ecosystems can’t build high quality user experiences.Rollups have emerged as the answer to this problem. Just as servers work together to scale compute in web2, so too can rollups scale onchain compute in web3. But building and operating your own rollup is difficult and time-consuming. That's where Conduit comes in.As the rollup-native cloud platform, Conduit combines web2 engineering best-practices with web3 rollup technology to make it easy for anyone to launch and maintain their own chain. By making infrastructure simple and onchain compute abundant, similar to how AWS and GCP did for web2, we can unlock the next wave of innovation in the crypto ecosystem.The Conduit platform has seen massive growth since going live in 2023. We run the largest chains in production, including Proof of Play, Zora, Aevo, and more. This translates to 200+ chains across mainnet and testnet and over $1B in total-value-locked (TVL). We're operating on the bleeding edge of crypto, co-evolving with our customers and integration partners, and pushing the limits of blockchain scalability and modularity.This success has been recognized and accelerated through a $37M Series A, co-led by Paradigm and Haun Ventures — two of the best investors in the industry.We’re an elite team that’s previously worked at Meta, Brex, Wish, Compound, Chainalysis, Immunefi, Amazon, Avara/Aave, Paradigm, and more. We’re headquartered in San Francisco, with team members all over the world.We’re looking for ambitious, talented builders that want to help scale Ethereum and bring crypto compute to the masses.
