Ethena Labs

## Staff/Senior Security Engineer - DeFi **Location:** Globally Remote **Department:** Ethena Labs – Engineering **Employment Type:** Remote --- ### 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. This product scaled from zero to $15 billion in 18 months. 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. Ethena has also developed **USDtb**: a fiat-backed GENIUS compliant stablecoin in partnership with BlackRock which has scaled to approximately $2 billion. 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. Through these offerings, Ethena Labs is not just creating new financial products; we are building the foundational infrastructure for a more open, efficient, and interconnected global financial system. Open job offerings will be focused on two new major product lines coming to market in the next few months. **Join us!** --- ### The Role We're hiring a **Staff/Senior Security Engineer** to lead our signing and treasury security program across wallets and custodian accounts. This is a high-impact, mission-critical role at the core of our business. 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. Your mission is to own the verification layer between operator intent and signature: independently confirming destination addresses, approvals, and calldata against on-chain truth, never just what a UI displays. 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. --- ### What You'll Do - Own the end-to-end design of our signing regime, including signer composition, thresholds, and intent communication, and continue evolving our pre-signature verification workflows for destination, calldata, and state-change confirmation. - Manage, maintain, and continuously upgrade the canonical address and contract allowlist system and the infrastructure 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. - Run independent technical reviews of new protocol integrations and keep our risk register current as positions and dependencies evolve. - Continuously verify ERC-20 approval hygiene across the treasury, and partner with Finance on automated reconciliation between on-chain activity and accounting systems. - Own the process of producing the documentation of controls, tooling, and decisions that our auditors, underwriters, and institutional counterparties expect. --- ### What We're Looking For - **Mastery of Solidity and the EVM** – you can read arbitrary contracts and raw calldata without assistance. You are fluent in tools such as Tenderly, Foundry-based simulation, and trace analysis. - **Deep practical experience** with Gnosis Safe, Coinbase Prime, Anchorage, and Fireblocks. Strong understanding of the operational failure modes inherent in browser-based custodian extensions and hardware wallet signing flows. - **Strong practitioner-level knowledge** of DeFi protocols like Aave, Morpho, and Stargate. You understand risk parameters, oracle structures, and bridge message-passing mechanics. - **A security-first mindset** that assumes a hostile environment by default. You possess a "vigilance disposition" – you are energized by rigorous verification and are committed to maintaining safety standards even when facing operational pressure. - **Proven ability** to explain technical risks to non-technical stakeholders (COO team, executives, auditors). You are a self-starter comfortable owning infrastructure end-to-end and producing high-quality, audit-grade documentation. --- ### Why Ethena Labs? You'd be joining a group that has well established itself as one of the most successful crypto-native companies of all time, a group with a mission to revolutionize decentralized finance and its position in global finance. - Work alongside a passionate and innovative team that values collaboration and creativity. - Enjoy a flexible, remote-friendly work environment with established opportunities for personal growth and learning. If you subscribe to the mission of separating the dollar from the state, then we want to hear from you! We look forward to receiving your application and will be in touch after having a chance to review. **In the meantime, here are some links to more information about Ethena Labs to help you check us out:** - **Website** - **Twitter/X** - **LinkedIn** --- *We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.* --- **When applying, mention the word CANDYSHOP to show you read the job post completely.**
