Senior Product Manager - Agentic Payments

Rain•New York, NY

11d•$200,000 - $250,000•Hybrid

About The Position

AI agents are already booking travel, subscribing to software, running procurement end to end, and moving money on behalf of users — much of it through Rain. Our Agent Control Layer is the governing surface for that activity: it enforces approved counterparties, amounts, merchants, and task scope at initiation, before a transaction ever occurs, rather than reconciling damage after the fact. We are hiring a Senior Product Manager to own that platform. This is a 0-to-1 role inside a category being defined in real time. You will own the developer-facing surface — APIs, SDKs, controls, docs — that teams building agents use to give them spending power safely. McKinsey projects $3–$5 trillion in global agentic commerce by 2030. The primitives that make it trustworthy have not been built yet. You will build them. You will report to the Head of Product and work daily with engineering, risk and compliance, network partnerships, and the developers shipping on us.

Requirements

8+ years in product management, with meaningful time on a developer-facing platform, API, or infrastructure product. You have shipped something engineers chose to build on.
Technical depth. You read API diffs, write your own queries, prototype against your own endpoints, and hold your own in an architecture review. You don't need to have been an engineer; you do need engineers to take you seriously.
0-to-1 instincts. You have taken a product from a blank page to real usage in an ambiguous market, and you're comfortable with a roadmap that changes because the ground moved.
Payments or fintech fluency, or the obvious appetite to acquire it fast. Authorization flows, issuing, interchange, chargebacks, settlement, KYC/KYB - you know these, or you'll learn them in weeks rather than quarters.
Judgment under risk. Every control you design trades capability against loss. You can reason about that tradeoff explicitly and defend where you landed.
Strong writing. At Rain, specs, docs, and launch narratives are the job, not overhead.
Bias for motion. You would rather ship a narrow thing this month and learn from it than scope a broad thing for two quarters.

Nice To Haves

Hands-on experience building or deploying AI agents - tool use, orchestration frameworks, MCP, evals.
Stablecoin or onchain payments background: settlement, custody, treasury operations, or wallet infrastructure.
Experience working directly with card networks, issuing processors, or sponsor banks.
Time at an early-stage company during a period of fast scaling.

Responsibilities

Define the primitives for agent authority: spend scopes, merchant and counterparty allowlists, velocity and amount ceilings, task-bound credentials, human-in-the-loop approvals, and clean revocation.
Own scoped virtual cards for agents — cards provisioned for a single merchant, amount, and task, retired the moment the task completes.
Extend the rest of Rain's stack (wallets, virtual accounts, onramps, offramps, cross-border payments) to agent initiators within the parameters our customers define.
Treat the API as the product. Own endpoint design, error semantics, idempotency, webhooks, sandbox and simulation tooling, SDKs, and reference agents.
Own documentation and the onboarding path with the same rigor as the product itself. Time-to-first-authorized-agent-transaction is your metric.
Run a tight design-partner loop with agent builders — read their integration code, sit in their debugging sessions, ship against what you find.
Build the roadmap from first principles: form a thesis on where agentic commerce goes next, sequence bets accordingly, and kill what isn't working quickly.
Partner with risk and compliance on Know Your Agent — agent identity, attestation, delegated authority, auditability, and dispute handling in a world where the cardholder wasn't the one who clicked.
Represent Rain's technical point of view in Agentic Payments Alliance working groups and with Visa, Mastercard, and stablecoin partners as standards take shape.
Write the specs, launch posts, and positioning that teach the market what controlled agentic payments actually means.
