Blockchain, Crypto & Web3

Governments and companies have failed to move the needle against many of humanity’s most important challenges and opportunities. We need new organizational structures. At Tephra Labs, we believe that decentralized human networks have the potential to be the right meta-coordinating structures for these large-scale problems. These networks can engage diverse participants and grow to unprecedented sizes (hundreds of millions of people). Further, they do not rely on the same kind of centralized direction-setting that is characteristic of governments and companies – making them lower overhead organizational structures overall. Tephra Labs’ mission is to enable large-scale human coordination to address humanity’s most important challenges and opportunities. We aim to build the infrastructure to scale decentralized networks to billions of people, and to support network participants in leading consistent, purposeful, and fulfilling lives. Our hypothesis is that hyper-scale decentralized networks will grow by engaging people as independent workers, rather than employees. So, we are building the necessary products, tooling, and services to help independent workers thrive. Our first product is Radius (https://radius.space). Radius is a decentralized network that connects independent workers and teams to the best projects in web3. As part of the Radius project, we are building decentralized reputation systems, skills attestation protocols, and a user-owned and value accretive economy. In accordance with our mission, we will also build educational curricula and programs to help train Radius workers and onboard them successfully into web3 work opportunities. We are excited to build the necessary infrastructure to enable the first billion-person organizations in human history. If this mission also inspires you, consider joining us.

Job description

ABOUT THE ROLE

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

WHAT WE'RE LOOKING FOR

  • 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

NICE TO HAVE, BUT NOT MANDATORY

  • 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

    • Unlimited time off 🌴 Unlimited vacation can be daunting, so we require Rainmakers to take at least 10 days off.

    • Easy to access benefits 🧠For US Rainmakers, we offer comprehensive health, dental, and vision plans for you and your dependents, as well as a 100% company subsidized life insurance plan.

    • Retirement goals💡Plan for the future with confidence. We offer a 401(k) with a 4% company match.

    • Equity plan 📦 We offer every Rainmaker an equity option plan so we can all benefit from our success.
