Senior Product Manager - Blockchain

As Senior Product Manager for Blockchain at Rain, you own the onchain surface — the blockchain layer that everything else at Rain depends on. 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 work closely with engineering, security, compliance, legal, and directly with fintech, neobank, and institutional partners to ensure stablecoins work as real-world money through fast, safe, and invisible onchain infrastructure.

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 including contract architecture and upgradeability, collateralization and liquidation logic, node and RPC reliability, gas and fee strategy, and bridging and cross-chain messaging, then translate them into partner-facing product decisions
• Decide which chains, assets, and stablecoins Rain supports and when by building a framework across liquidity, security, cost, partner demand, compliance considerations, and regulatory exposure
• Drive the security bar for onchain work through audits, monitoring, incident response, and operational guardrails for 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

What you bring

• 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 with the ability to reason unaided about EVM and Solana mechanics, 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 including APIs, distributed systems, payments and ledger design, with the instinct to pull on technical threads yourself rather than defer to engineering
• Genuine excitement for living 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 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

Nice to have

• 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 including Solana, Tron, and Bitcoin L2s, plus 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

What we offer

• Unlimited time off with a minimum of 10 days per year
• Flexible working arrangements, with the option to work from home or in an office; new team members receive a stipend to create a comfortable home environment
• Comprehensive health, dental, and vision plans for you and your dependents (US only), plus a 100% company subsidized life insurance plan (US only)
• 401(k) with a 4% company match (US only)
• Equity option plan available to all team members
• A Rain Card to test core products and services, which can also be used for eligible health and wellness spending such as gym memberships, fitness classes, massages, and acupuncture
• Team and company off-sites both domestically and internationally
