Gopher AI
Risk manager - Crypto
New York, USA
New York, USA
Full time
Remote
About Gopher AI
At Gopher AI, we’re building a decentralized data layer for the AI-driven future — a protocol where transparency, verifiable data, and human alignment truly matter.
Our mission: make data trustless, provable, and usable across AI, DeFi, and on-chain applications.
We’re growing fast — and now looking for a Risk Manager who understands not just traditional risk, but on-chain dynamics, token economics, and crypto-native behavior.
Your Mission
You’ll be the brain behind risk strategy across Gopher’s ecosystem — balancing decentralization with resilience.
From smart contract exposure to liquidity risk and treasury management — your job is to make sure every piece of the system is solid, compliant, and forward-looking.
What You’ll Do
Design and maintain comprehensive risk frameworks tailored to Web3 systems (protocol, liquidity, counterparty, smart contract).
Monitor and analyze on-chain activity, market volatility, and ecosystem health to identify emerging threats.
Work closely with treasury, quant, and governance teams to ensure risk-adjusted strategies.
Establish and document risk policies and mitigation plans (both operational and token-economic).
Contribute to internal audits, compliance with applicable jurisdictions, and protocol transparency.
Engage with community and DAO contributors to maintain open risk communication
You’re a Great Fit If You
Have 3–5+ years in risk management, quantitative finance, or DeFi / crypto projects.
Know your way around DeFi protocols, liquidity pools, staking, on-chain analytics tools (Dune, Nansen, Arkham, etc.).
Understand tokenomics, smart contract audit principles, and treasury diversification strategies.
Feel at home reading Etherscan, analyzing TVL, and tracking wallet flows.
Communicate clearly, document well, and think both strategically and hands-on.
(Bonus) Have contributed to DAOs or Web3 protocols before — or maybe you’ve been a degen with a spreadsheet.
Why Join Gopher AI
🌍 100% remote, async-first culture
🧠 Work at the intersection of AI x Web3 — future of verifiable data
💸 Competitive crypto-based compensation + token incentives
⚡ High ownership, zero bureaucracy — you build, you ship, you own
🕶️ Join a small team of builders who actually ship things on-chain
