We're looking for an experienced Solidity engineer to help us bring Ethereum to millions more people with our . Our L2 wallet will be smooth, secure and have radically lower gas - all while keeping the unique experience Argent is known for.

We're aiming for a breakthrough in the global adoption of crypto.

  • On Layer 1, you'll help us integrate more Defi protocols to the existing which combines multisig security with one tap DeFi and protects over $1bn in assets.
  • On Layer 2, you'll help us bring our unique smart-contract model to key rollups. We're starting on zkSync but will expand to other L2s, such as Optimism, Starkware and Arbitrum afterwards.
  • For both initiatives you'll take ownership of the entire smart contract development lifecycle, including managing relations with partners and deploying the contracts to our test and production environments.


  • 3+ years as a software engineer
  • 1+ years experience developing top tier smart contracts on mainnet
  • Deep understanding of Solidity, Assembly, and the EVM
  • Writing code that's clean, easy to audit, yet efficient in terms of deployment, execution and maintenance.
  • Experience with smart-contract patterns such as upgradability, proxy wallets, meta-transactions, and counterfactual deployment
  • Good knowledge of the L2 ecosystem, with a deep understanding of ZK and Optimistic rollups.
  • Nice to have

  • Passionate about the evolution of Solidity and the EVM
  • Being an active member of the dev community (e.g. experience contributing to EIPs)
  • Ability to work well with design, mobile platform and backend teams
  • Enjoys working on unfamiliar problems, challenging others and being challenged in turn
  • Knowledge of Rust, Javascript, Typescript or Node.js is a plus
  • Benefits

  • Work remotely - anywhere in Europe (but Europe only). No commute. Lots of flexibility. Plenty of time to care for your kids or cats.
  • Equity in a high growth startup backed by the investors of Spotify and Slack.
  • Autonomy - you decide how to achieve your best work.
  • Trips across Europe - for one week every three months we collaborate in person, explore new solutions and have fun. So far we’ve stayed in Nice, Toulouse, Brussels, Lisbon and Barcelona.
  • We'll resume these when safe following COVID.

  • Equipment - pick the tech setup of your choice.
  • Parental leave - generous package for new parents.
  • Build a new industry - help define the future of the web.
