Who are we

Buidlers at heart and decentralization advocates. Our team is funded by former MakerDAO Core Unit members, with the goal of supporting web3 projects to design and implement their vision with Smart Contracts.

We like to spend our time immersed in Solidity code, building the foundation and infrastructure for decentralized finance, DAOs, and Web3. For the time being, we chose to conceal our identities, and build our reputation around pseudonyms to protect our privacy and ourselves from authoritarian people, entities and governments.

Our team is looking to onboard other like-minded people, Senior Engineers, that understand the inner workings of the EVM, can build sound and secure Solidity code, and folks that always have a keen eye for optimisation and engineering best practices.

As part of our team, you’ll most probably work on:

  • Digging into Intent protocols such as CowSwap, Uniswap X, 1inch, Across, chain abstraction protocols, APIs, Liquidity Sources and beyond.
  • Designing and implementation of liquidity sources and protocol abstractions.
  • Designing and implementation of bid and gas optimisations.
  • Defining solver strategies to make our solver engine win all the solver competitions across many EVM chains.

What’s in it for you

  • Work on the verge of decentralization, novel Intent Architecture and Cross-chain challenges.
  • Be part of a remote first, fully autonomous team, that believes in ownership, responsibility and accountability, so we can all enjoy our flexibility.
  • Yearly team gathering at a Web3 conference, all expenses included.
  • Hardware and accessories required to make your job easier.
  • Yearly training and experimentation budget.
  • Leave a mark in the world, shape how we transact, interact and collaborate.

Job requirements

  • Algo trading experience.
  • Have worked or integrated with DEX aggregators and DEX/CEX/RFQs (ie. routing algos).
  • 5+ years of Backend experience with NodeJS preferred, Rust or Python also desirable.
  • Service Architecture.
  • 2+ years of experience on Web3 EVM chains.
  • Smart contract experience is required as the job will involve designing and implementation of many integrations.
  • Smart contract implementation will be rare, but useful.
  • AWS experience is a nice to have.
