Maker is a smart contract platform on Ethereum that backs and stabilizes the value of the Dai stablecoin through a dynamic system of Collateralized Debt Positions (CDPs), autonomous feedback mechanisms, and appropriately incentivized external actors. It is a decentralized infrastructure without a central operator.

It is one of the oldest Ethereum projects with very experienced technical team of blockchain developers. We believe in a future that leverages the power of decentralization for trustless transactions. With Maker, we are carrying out our vision of creating a decentralized stablecoin that will unlock unique benefits of a complete financial ecosystem on the blockchain, and democratize financial inclusion.

Distributed Teams

We form our teams around availability of talent into co-located or distributed agile teams. In the techops team, you will work together with our chief techops/devops engineer to help define, implement, and maintain security strategy and policies across the decentralized Maker organization.

We have offices in Copenhagen, Warsaw, London, Buenos Aires, San Francisco, New York, and Singapore, but it is also possible to work remotely in this position. The responsibilities sometimes require working evenings and weekends, sometimes with little advance notice. No regular travel is required.
