SmartDeFi is Introducing a New Value Layer: DeFi Risk Assessment.

We are seeking a Senior Solidity Developer to help us make that happen.

What is DeFi?

DeFi (Decentralized Finance) is a democratized alternative to the current system CeFi (Centralized Financial), where individuals can take control of their finances without the cost and risks of relying on intermediaries.

What is SmartDeFi?

SmartDeFi is an easy to use, non-custodial investment app which fulfills the needs of traditional investors who want to make their first DeFi investments, but don’t understand the risks involved or how to take the first steps. 

Job Description

SmartDeFi has recently closed Pre-seed funding and will be launching an MVP iOS app in April 2021. 

The MVP app is built on Idle Finance (DeFi Protocol), Gnosis Safe (Multisig), Wyre (Fiat Onramp), Torus Directauth (Web3 Login), and the Layer 2 platform Polygon (formerly Matic Network).

SmartDeFi is hiring a Senior Solidity Developer for long term employment. This is a ground floor opportunity at a funded Web3 startup. You will be working directly with the CTO and lead developer on a daily basis; with an initial focus on Layer 2 scaling and transaction batcher infrastructure.
