Rust Backend Senior/Lead Developer

About DefiTuna

DefiTuna is a young project in the Solana Network, launched on the mainnet 1 year ago. The protocol is bringing innovation to Solana, specifically in the Lending market. We provide tools for both lenders and liquidity providers, offering some of the highest lending rates in the blockchain space. We pride ourselves on being at the forefront of innovation. For liquidity providers, we enable farming with leverage to amplify rewards, allowing LPs to take bigger risks and other innovations in DeFi.

After a very successful launch and experiencing rapid userbase and TVL growth, we're looking to add a senior fullstack developer with a strong focus on frontend to join our team.

The protocol has experienced strong TVL growth, accompanied by several thousand daily transactions, creating a serious challenge for our team and business. This presents a serious technical and business challenge. We are looking for a strong candidate who can contribute during this phase of rapid growth, implement a wide range of new features, and help take the project to the next level.
