About the role
As a Blockchain Security Researcher on the Security Services team, you will secure leading web3 protocols and top financial institutions building onchain. You will partner with client engineering teams across the entire lifecycle of a protocol—analyzing design and architecture before code is written, conducting deep audits of pre-launch codebases, and using modern AI tooling to build repeatable skills, agents, and auditing workflows. Additionally, you will perform open-ended research into new attack vectors and contribute knowledge back to the broader blockchain ecosystem.
What you'll do
- Review smart contracts for top decentralized applications, blockchain infrastructure, and financial institutions to identify and prioritize vulnerabilities.
- Drive audits independently from start to finish, leveraging AI as a primary collaborator to pressure-test code and findings.
- Partner with client teams during early protocol design to evaluate architecture, trust assumptions, and operational constraints.
- Develop and share AI skills, agents, prompts, and automated workflows that elevate security practices across the team.
- Conduct open-ended research into cutting-edge blockchain technologies and emerging vulnerability classes, publishing findings to internal and external knowledge bases.
What you bring
- Practical hands-on experience in software development, cybersecurity, applied mathematics, distributed systems, cryptography, cryptoeconomics, or DeFi mechanisms.
- Experience designing and developing smart contracts, not solely auditing them.
- Strong working knowledge of Solidity and the broader Ethereum / EVM ecosystem.
- Daily utilization of modern AI tooling to expand audit coverage, reason through complex systems, and build custom workflows.
- Advanced English proficiency with strong written and oral communication skills.
