About the Role

Saifuro 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 queue where a person says yes or no to a payment an agent couldn t make alone, on a laptop or a phone, in a few seconds. • The design system. Components, type and color the frontend engineers build from, so a new screen looks like it belongs. • What s next. Early next year the sandbox opens to every developer without a sales call, and the sign-up and first steps need designing. Budget forecasting follows later in 2027, and you ll design it from the first sketch. What we need from you • You ve designed for a crypto, fintech or developer product. • 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 diffe...
