Staff/Senior Security Engineer - DeFi
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 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.
-
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.
How do I get a job at DeFi?
Getting a job in the DeFi (decentralized finance) industry can be a competitive process, but there are a few steps you can take to increase your chances of finding a job in this field:
- Build up your skills and knowledge: To work in DeFi, you'll likely need to have a strong understanding of blockchain technology, as well as other related technologies such as smart contracts and cryptocurrency. Consider taking online courses or earning a degree in a relevant field to build up your skills and knowledge.
- Network with industry professionals: Attend meetups and conferences related to DeFi and make connections with professionals in the industry. Networking can be a valuable way to learn about job openings and get your foot in the door at a DeFi company.
- Create a strong online presence: Many DeFi companies will look at your online presence (such as your LinkedIn profile and personal website) when considering you for a job. Make sure to showcase your skills and accomplishments online and keep your profile up to date.
- Apply for relevant job openings: Keep an eye out for job openings at DeFi companies and apply for positions that align with your skills and experience. Apply for DeFi Jobs without Experience. Tailor your resume and cover letter to the specific job you're applying for and highlight any relevant experience or skills you have.
- Consider internships or volunteer work: DeFi Internships or volunteer work can be a great way to get your foot in the door and gain valuable experience in the DeFi industry. Many companies also offer internships to students, so consider applying for an internship if you're still in school.
- Be persistent: keep trying if you don't get a job right away. It can take time to find the right opportunity, but with the right skills and determination, you can land a job in the DeFi industry.
