Mission
DeFi loans are capital-inefficient, and a lot of work to manage. We fixes this.
We are a unique DeFi protocol which delivers the lowest borrow rate on the market and offers very attractive loans that repay themselves. We do this by programmatically managing loans and collateral for our users. Our team has been in the crypto space for many years and the protocol was born out of personal need.
About Us
We are a well-funded early-stage company. We are a lean & fast-moving team of ~7 people and are building something that hasn't been built before. We've raised over $6M in funding from prominent investors deeply involved in the Web3 space. We believe in decentralization, open source, and composability.
Even though were still in closed beta, we've already attracted almost $5M in deposits and 40+ users.
About The Role
We're looking for a meticulous full-stack engineer with a knack for juggling a diverse range of technologies. This role needs someone who likes diving into coding bots, reporting, front ends and an occasional Smart Contract with equal passion and precision.
You'll work directly with our CTO and in a small team. This gives you the opportunity to learn fast and take ownership of an important part of our protocol.
If you like contributing to a system with direct financial implications for users and want to strengthen your skills in Web3 this might be the perfect position for you.
Building and maintaining libraries that glue our applications together (e.g. SDK, APIs)
Developing bots for monitoring and executing on-chain transactions
Integrating data into dashboards using GraphQL
Building comprehensive test suites (not tested ready)
Generating and preparing data for reporting and analysis
Creating and updating subgraphs to expose blockchain data
Developing and maintaining our React front-ends
Integrate with existing Smart Contracts and writing an occasional Solidity contract
While prior experience in Web3 and Solidity will be a bonus, we welcome applicants who are new to these areas but have demonstrated an aptitude to learn and grow.
