We are seeking a seasoned and visionary blockchain security auditor to help secure our blockchain and crypto initiatives. The ideal candidate will have deep expertise in Ethereum and Solidity, along with experience in other platforms like Rust and Solana, and at least one year of hands-on auditing experience. While knowledge of other emerging technologies-such as AI security, gaming platforms, software bots, and social media-is a plus, it's not required. This high-visibility, individual contributor role demands strong technical acumen, strategic thinking, and cross-functional collaboration. As part of a team of subject matter experts, the auditor will guide secure development practices, perform smart contract reviews, and contribute to cybersecurity strategies across emerging technologies. Responsibilities include staying current with technological advancements, researching and documenting best practices, monitoring vulnerabilities, and developing training materials. The role also involves partnering with Enterprise Cybersecurity teams to enhance Fidelity's overall security posture.
