Who We Are and What We are Doing: Ethena Labs is actively building and deploying a suite of groundbreaking digital dollar products aiming to upgrade money into the internet era.
Our flagship product, USDe, is a synthetic dollar backed by digital assets, and takes the novel approach of using a delta-neutral hedged basis strategy to maintain its peg. Expanding on this, iUSDe is designed specifically for traditional financial institutions, incorporating necessary compliance features to enable them to access the crypto-native rewards our protocol generates, in an institutional-friendly manner.
These products are also offered in a whitelabel stablecoin offering where any application, chain, wallet or exchange can launch their own stablecoin on Ethena's back-end infrastructure.
we are building the foundational infrastructure for a more open, efficient, and interconnected general financial system.
We're hiring a Staff/Senior Security Engineer to lead our signing and treasury security program across wallets and custodian accounts. Operating within the security department,



you will partner closely with our core DeFi and trading teams to provide an objective security perspective while engineering safe, streamlined operational workflows.
The work bridges complex on-chain security with daily operations, securing defensible audit trails, robust infrastructure, and controls built to scale with Ethena's growth.
Manage, maintain and continuously upgrade canonical address and contract allowlist system and infra that manages it, ensuring every whitelisting or approval action is checked against this list pre-signature, requiring documented review for any additions.
Operate and tighten real-time monitoring across wallets, custodians, and DeFi positions, keep it integrated with our SOC 2 incident-response workflows, and contribute to playbooks for evolving risk scenarios.
Continuously verify ERC-20 approval hygiene across the treasury, and partner with Finance on automated reconciliation
