As a foundational engineer at Sapiom, you will build the critical payment and identity rails that allow AI agents to operate autonomously in the real economy. You will own entire systems end-to-end, from KYA (Know Your Agent) protocols to multi-rail payment execution, defining how machines trade and transact at scale.
Software Engineer at Sapiom — VC-backed Agentic Fintech
The agentic economy is arriving fast, but AI agents still can't autonomously access real-world services. Sapiom is building the missing link: the financial infrastructure for the AI era. Backed by $15M from Accel, Anthropic, and Coinbase Ventures, we’re looking for elite engineers from the likes of Stripe and Vercel to build KYA, agent wallets, and multi-rail payments. If you want to build the rails that let AI agents buy, sell, and negotiate on our behalf, this is your opportunity to join a category-defining team in San Francisco.
