Full Job Description
Position Overview:
We're looking for an exceptionally strong Senior Smart Contract Engineer with a security focus. You'll design and build contracts that protect billions of dollars in user assets, review the changes that matter most, and help shape how we deploy, operate, and monitor our on-chain systems. You'll work closely with engineering leadership and have real influence over our security practices from day one.
What You'll Work On:
Design, build, and own smart contracts across Stake, Liquid, and Cash, with safety built into the design: limited blast radius, clear access control, and safe upgrade paths
Review and audit contract changes before they reach mainnet, and serve as a go-to reviewer for the rest of the team
Work with external auditors from scoping through fix verification
Help design and improve how we sign transactions, including multisig structure, signer workflows, calldata and transaction hash verification, and timelock usage
Improve how we run on-chain operations such as upgrades, parameter changes, role grants, fund movements, and bridges, so each follows a clear, reviewable path
Build monitoring and alerting for contract state, privileged actions, oracle behavior, and anomalous flows, and contribute to incident response playbooks
Propose and drive security practices and policies, and help other engineers write safer contracts
You Might Be a Fit If You:
Led a smart contract team and the dapps operations
Strong programming & design skill in Solidity
Built sophisticated DeFi apps from scratch and operated
Strong fundamentals in software engineering & enjoys problem solvings.
Obsessed with Security: Care about secure smart contract code, and think deeply about edge cases and failure modes.
Strong understanding of upgrade patterns, access control, oracle and risks, cross-chain messaging, and common DeFi attack vectors
Experience operating with multisigs, timelocks, and governance flows in production
Sound judgment on tradeoffs between safety and shipping speed, and the ability to explain them clearly
You use AI tools heavily and reliably to review code, investigate issues, and automate operational work
Benefits:
Competitive salary, performance-based incentives, and token allocation grant
Health, dental, and vision insurance plans
Collaborative and inclusive work culture
Exposure to cutting-edge technologies in the blockchain and cryptocurrency space
Global team with opportunity for travel and working out of our 3 offices around the world
