At Zwieco, our mission is to build the portal between the rich ecosystem of Web 2 endpoints and the emerging landscape of Web 3 applications. We believe that developers should be able to set up production-grade pipelines to off-chain endpoints in under five minutes. The bridge between the off and on-chain worlds is so much more than price feeds and random numbers. Talk to us and we’ll tell you how. As a Lead Blockchain Engineer you will be responsible for the design and development of core smart contracts built on Ethereum and EVM chains. You will work alongside our founding software engineers and have technical decision making authority for the architecture and design of on-chain elements of our core product. You will help build out a team of Blockchain Engineers who will report directly to you. We want someone who is comfortable in a role that has the responsibility of defining large technical components of a new product. Why work at Zwieco? - Our entire team is technical. The blockchain space is still nascent and to build something meaningful today you need a technical team and leadership that understands blockchain at a protocol level. No more explaining what can and can’t be done in a smart contract to non-technical PMs and execs. - Our founding team is experienced. Our founder left school in 2019 to grow a hardware/computer-vision startup from tinkering in a Stanford dorm room to a $240M business with hardware deployed across the country. We understand how to start and grow a company and intend to use those lessons to grow quickly. - We are venture-backed and we work in-office. No more developing on discord or waiting to hear back on grant funding. We are fully venture-backed with $3M in capital and are deploying it to build a strong engineering team. Working out of our office in San Francisco provides for rapid communication and development that is necessary to get a product from zero to one. - We are a blockchain infrastructure company, not a cryptocurrency company. In order to build a sustainable business, you need to provide a service with a recurring source of revenue. Too many companies in the blockchain space instead opt for business models based on price speculation instead of providing long-term value. We understand that this works in a bull market but does not work in the long-run. Experience - 5+ years of industry software engineering experience (any kind of role). - 1.5+ years as a Smart Contract Engineer, Blockchain Engineer, Solidity Engineer or similar role. - Experience building on Ethereum or other EVM-compatible chains in Solidity or Vyper. - Experience with deploying production contracts to a live ‘mainnet’. - Experience with developing and testing contracts in local environments and on public testnets. - Strong understanding of core blockchain principles (ex. EVM client, EIP-1559 gas fees/price, consensus mechanisms, layer 2 solutions). - High-level understanding of popular data availability and oracle protocols (ex. Chainlink, The Graph, IPFS). - Degree in Computer Science, Math, or a related technical field. - (Optional) Experience as a node operator - any project. - (Optional) Experience in a Security Engineer, Privacy Engineer, Network Engineer role. - (Optional) High-level understanding of ZK proofs and public-key encryption.
