Smart Contract Engineer (Solidity, EVM)
标签：Web3工作 • Web3开发人员工作 •区块链稳定性工作 •加密货币智能合同工作 •区塊远程工作 •区分类全职工作 Saifuro 检查人工智能代理试图支付的支付。一个代理要求花费，我们将请求与之前批准的人权相比较，答案得到了签署后，以便接收方可以验证它。在代理之间交易时，Base 和 Solana 有保险，和解是在 USDC 上进行。我们从来没有持有客户资金。文件在 docs.saifuro.com 上是公开的，使用者是开发人员构建代理和向这些代理销售 API 的团队。保证券是我们代码存储别人的钱的地方。资金进入，坐在那里直到签署判决说交易完成，然后出卖方或回购商，没有 Saifuro 可以移动它们的路径。你的工作就是拥有 EVM 方面：保证券，验证器检查我们的签名链，审计和部署。如果你喜欢的话称之为 Solidity 开发者，智能合同开发者或区块链开发者。首先是 Solidity.•你会做什么？保证券。一个合约系统基于：根据签署的判决，将获得资金，并没有任何途径可以通过 Saifuro 移动对方的钱。设计，代码和测试都是你的.•验证者。合同检查我们的签名，观众和任何东西移动之前的期限。你拥有该路线.CTO 运行签字侧并审查你的代码.•审核和发布。每次主网发售前进行外部审计。你在调查中回答结果，并随着部署脚本，暂停开关和恢复跑本一起出货.•下一步，以你的速度来做什么。明年里程碑和多方保险，并在更多 EVM 链上完成相同的合约。任何一项工作都不是一个日期的要求。我们需要你•你已经将 Solidity 送到 mainnet 中.•你居住在我们可以聘请的国家之一。除了这些要求之外，我们会支持你学习其他角色所需的一切。如果你的经验是相关的，但你的头不同，我们仍然希望听从你。在职位以外的工作也很重要：开源，黑客赛车和自己的项目。如果你知道存储布局，重新进入和电子商务水平上的签名验证，如果你写过 Rust 或 Anchor 程序在 Solana 上，如果你曾与账户抽象 (ERC-4337) 或为代理人进行会议密钥合作，如果你了解 Circle 的 USD 数据库，它有帮助，但不必需。

Tags: Web3 Jobs • Web3 Developer Jobs • Blockchain Solidity Jobs • Cryptocurrency Smart Contract Jobs • Blockchain Remote Jobs • Blockchain Full Time JobsSaifuro checks payments that AI agents try to make. An agent asks to spend, we compare the request with a mandate a human approved earlier, and the answer comes back signed so the receiving side can verify it. There's escrow on Base and Solana for trades between agents, and settlement is in USDC, onchain. We never hold customer funds. The docs are public at docs.saifuro.com, and the people who use them are developers building agents and the teams selling APIs to those agents.The escrow is the one place where our code holds other people's money. Funds go in, sit until a signed verdict says the deal is done, and come out to the seller or back to the buyer, with no path in which Saifuro can move them. Your job is to own the EVM side: the escrow, the verifier that checks our signatures onchain, the audits and the deployments. Call it Solidity developer, smart contract developer or blockchain developer if you prefer. It's Solidity first.What you'd be doing• The escrow. One contract system on Base: funds held until a signed verdict releases them, refunds that work without us, and no path in which Saifuro can move a counterparty's money. Design, code and tests are yours.• The verifier. The contracts check our signature, the audience and the expiry before anything moves. You own that path onchain. The CTO runs the signing side and reviews your code.• Audits and releases. An external audit before every mainnet release. You scope it, answer the findings and ship, with deployment scripts, a pause switch and a recovery runbook alongside.• What comes next, at your pace. Milestone and multi-party escrow next year, and the same contracts on more EVM chains. None of it is a day-one requirement.What we need from you• You've shipped Solidity to mainnet.• You live in one of the countries we can hire in.Beyond these requirements, we'll support you in learning whatever else the role demands. If your experience is relevant but your title differs, we would still like to hear from you. Work outside a job counts too: open source, hackathons and your own projects.It helps, but isn't required, if you know storage layout, reentrancy and signature verification at the EVM level, if you've written Rust or Anchor programs on Solana, if you've worked with account abstraction (ERC-4337) or session keys for agents, if you know Circle's USDC contracts and CCTP, if you've found bugs for a bounty or done security research, or if your work is open source.Pay and benefits• Salary $170,000 to $220,000. That's the US range. Outside the US we pay in USD, or in USDC if you'd rather, and set the offer against the top of the local market.• Equity: 0.30% of Saifuro, vesting.• Health: 100% of medical, dental and vision premiums for US employees, 75% for dependents. Outside the US, the local plan through our employer of record, or $300 a month toward private cover.• 25 days of paid vacation plus your public holidays, and we close between Christmas and New Year.• 14 weeks of paid parental leave, for any parent.• A laptop and $1,000 toward your workspace.• $1,500 a year for learning, conferences included. That's on top of the events you'll attend for work: six to eight a year, planned a quarter ahead, on the company.Hours are flexible. The one thing we ask is to be online from 14:00 to 17:00 UTC, when the team overlaps for calls and quick questions. That's a window, not the working day. The rest of your hours are yours to arrange. A mainnet incident doesn't keep office hours. If that window is the middle of your night, say so and we'll work something out.You can combine this with a job at another company, as long as the two don't conflict and nothing you'd write there touches our contracts or competes with them.How to applyEmail with the subject "Smart Contract Engineer (EVM)".
