Job summary

Rain is hiring a Senior Product Manager to own the Agent Control Layer platform, APIs, SDKs, and documentation that enable agents to transact with controlled spending power.

You will report to the Head of Product and collaborate daily with engineering, risk/compliance, and partnerships to build the primitives and governance for agentic payments at scale.

Qualifications

• 8+ years in product management, with meaningful time on a developer-facing platform, API, or infrastructure product.
• Technical depth and ability to read API diffs and prototype against endpoints.
• 0-to-1 instincts for taking a blank page to real usage in an evolving market.
• Payments/fintech fluency or willingness to learn quickly.
• Judgment under risk when designing controls that trade capability against loss.
• Strong writing for specs, docs, and launch narratives.
• Bias for motion: shipping tangible results quickly.

Responsibilities

• Define primitives for agent authority including spend scopes, allowlists, and ceilings.
• Own scoped virtual cards for agents, provisioned for a single merchant, amount, and task.
• Extend Rain's stack to agent initiators within customer-defined parameters.
• Treat the API as the product with design, error semantics, idempotency, and tooling.
• Own onboarding and documentation with time-to-first-authorized-agent-transaction as a metric.
• Run design-partner loops with agent builders and ship against feedback.
• Build the roadmap from first principles and prune what isn't effective.
• Partner with risk and compliance on Know Your Agent and related controls.
• Represent Rain's POV in industry groups and with Visa/Mastercard as standards form.
• Write specs, launch posts, and market positioning for controlled agentic payments.

Job description

About the Company

Rain is the global stablecoin payments platform for enterprises, neobanks, platforms, developers, and AI agents. Our technology allows partners to move, store, and use stablecoins instantly and compliantly through global payment cards, rewards, on/offramps, wallets, and cross-border rails. As both a Visa and Mastercard Principal Member, Rain issues cards that work at more than 175 million merchant locations in over 220 countries and territories. Built natively for stablecoins and trusted by more than 100 organizations worldwide, Rain delivers secure, scalable infrastructure that makes money move freely and instantly around the world.

You will have the opportunity to deliver massive impact at a hypergrowth company backed by some of the top investors in fintech, crypto, and SaaS. In January 2026, we closed a $250M Series C led by ICONIQ, valuing Rain at $1.95B, with Sapphire Ventures, Dragonfly, Bessemer Venture Partners, Galaxy Ventures, FirstMark, Lightspeed, Norwest, and Endeavor Catalyst also participating. If you're curious, bold, and excited to help shape a borderless financial future, we'd love to talk.

Our Ethos

We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company.

About the Role

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.

What you'll do

• 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.

You’ll likely succeed if you have

• 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.

Bonus attributes

• 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.
