Founding AI & Cloud Engineer

San Francisco, CA (North Beach) · On-site · Full-timeCompensation: $150,000–$200,000 + 0–2% equity

About the Company

Our client is building the financial infrastructure for the agentic web — turning intent into action by giving AI agents a dependable way to reach businesses, prove who they're acting on behalf of, and pay for what they transact.

It's framed as the third iteration of the internet: the first was built for eyes and fingers (documents), the second for apps (walled gardens), and this is the third — a web built for agents. It was founded by experienced payments operators paired with a founding engineer from a major search team, and is positioned as one of the first teams building end-to-end agentic purchasing.

Founded 2024 · Seed · Industry: FinTech / AI

The Role

The client is hiring a Founding AI & Cloud Engineer to build the products end to end, working across the stack from the interfaces merchants and developers use to the services and data behind them — with particular focus on a programmable, scope-limited agent-wallet product (payment credentials tied to a user's existing card) and an agent-checkout product (agents completing real transactions across commerce protocols and payment providers), alongside the founding team on the core AI and agent features.

Tech stack: JavaScript-based, with Python for MCP, all on AWS.

Requirements

• 0–3 years of engineering
• Agent-harness / agent-building experience
• High agency, opinionated, a generative thinker
• On-site in SF (North Beach), 5 days a week plus occasional weekends
• A scrappy, AI-native generalist (not a 10-year infra specialist)
• Substantial full-stack experience, frontend and backend
• TypeScript, JavaScript, or Python fluency
• API-design experience with an eye for clarity and stability
• AWS familiarity and willingness to operate what you build

Nice to Haves

• A strong agent-harness or agent-building portfolio
• A hackathon-heavy background paired with shipping discipline
• A scrappy, AI-native generalist with side projects and high agency
• Fintech adjacency (Stripe, Plaid, Visa, crypto startups, payments tools)
• Comfortable being raw and malleable, wanting more responsibility than you've had so far

Why Join

• A founding seat with real latitude: an early engineering hire with direct influence over the product and the engineering culture
• A genuinely novel space: experienced payments founders building end-to-end agentic purchasing — an approach nobody else is taking
• Full-stack ownership from day one: build across the two core products, from merchant/developer interfaces down to services, APIs, and data models
