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 Team

Rain is hiring a Senior Product Manager to own our onchain surface — the blockchain layer that everything else at Rain depends on. Stablecoins only work as real-world money if the onchain side is fast, safe, and invisible: collateral held in contracts, settlement across chains, custody and wallet architecture, and the asset and network coverage our partners need to operate globally. This role owns that.

This is a senior individual contributor role. You'll be the directly responsible PM for onchain end to end: smart contracts and protocol design, chain and asset integrations, settlement and treasury flows, and the infrastructure underneath it all. You'll work closely with engineering, security, compliance, legal, and directly with our fintech, neobank, and institutional partners.

What you’ll do

- Own the roadmap for Rain's onchain product — smart contracts, chain and asset coverage, settlement, and payments — and drive it end to end

- Partner deeply with engineering on protocol and infrastructure tradeoffs (contract architecture and upgradeability, collateralization and liquidation logic, node/RPC reliability, gas and fee strategy, bridging and cross-chain messaging) and translate them into partner-facing product decisions

- Decide which chains, assets, and stablecoins Rain supports and when — build the framework for those calls across liquidity, security, cost, partner demand, compliance considerations, and regulatory exposure

- Drive the security bar for onchain work — audits, monitoring, incident response, and the operational guardrails that go with holding real value onchain

- Translate complex protocol and blockchain infrastructure into intuitive product surfaces and clear partner-facing documentation

- Gather feedback directly from partners, distill it into sharp prioritization, and push the team toward the highest-leverage work

- Measure ruthlessly, iterate quickly, and set a bar others want to work to

You are likely to succeed if you have:

- 8-10 years of product management experience, with a track record of shipping products from zero-to-one through scale at a product-led company with a strong engineering culture and high bar for quality

- Deep, hands-on blockchain fluency — you've shipped onchain products and can reason unaided about EVM and Solana mechanics (and other chains), smart contract design and upgrade patterns, gas economics, bridging models, and other onchain tradeoffs

- Exceptional product judgment and analytical rigor — you're someone others describe as one of the sharpest PMs they've worked with, and you consistently raise the bar for the people around you

- A senior, autonomous operator who can define the problem, drive the plan, and own the outcome without needing close direction

- Sound instincts on onchain security and risk: you know where value gets lost, you push for audits and monitoring before incidents rather than after, and you can weigh a shipping deadline against a real risk without flinching

- Strong technical fluency beyond the chain itself (APIs, distributed systems, payments and ledger design) and the instinct to pull on technical threads yourself rather than defer to engineering

- Genuinely excited to live in the details — you believe product quality is won in the specifics and are energized by the work to get them right

- Excellent written and verbal communication; you can operate with sophisticated external partners and internal engineering teams with equal ease

- Proven ability to ship quickly, measure adoption, and iterate in a fast-moving environment

Bonus attributes:

- Experience with stablecoin issuance, onchain lending or collateralized credit, or tokenized asset products

- Background at a protocol, L1/L2, wallet, custodian, or onchain infrastructure company

- Familiarity with non-EVM ecosystems (Solana, Tron, Bitcoin L2s) and multi-chain operations at scale

- Experience with payments, card issuing, or cross-border fintech products

- Working knowledge of the regulatory landscape around digital assets and custody

- Previous startup or hypergrowth environment experience
