About Trail of Bits
Trail of Bits serves clients in the defense, tech, finance, and blockchain industries. We help with their most difficult security challenges by designing and building new technology, researching new techniques to advance the state of practice, and reviewing the security of the latest available technology products before they hit the market.

Our research team is looking for self-motivated teammates interested in exploring low-level technologies. We focus on discovering vulnerabilities, traversing security boundaries, and executing arbitrary code. You are expected to be at the forefront of security: researching, discovering and exploiting vulnerabilities in complex systems with millions of lines of code and the most advanced modern mitigations. Our team is fully remote, with a strong culture of teamwork and an interest in difficult projects. We often work in small fluid teams of 2-3 people, and encourage all researchers to learn from and contribute their expertise to all ongoing projects. We encourage moving between projects so as to develop and grow our internal expertise. We value creativity and deep understanding of software. Solid engineering skills are required for developing custom tooling to assist in your work. We encourage frequent communication between team members as it is essential to our success.
