About Trail of Bits
Trail of Bits helps secure the world’s most targeted organizations and products. We combine high-end security research with a real-world attacker mentality to reduce risk and fortify code.

As a cybersecurity research and consulting firm, we serve 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 team consumes, produces, and presents research as a natural part of doing business. When we make new discoveries or developments, we strive to share our knowledge and release our tools as open-source. It’s a practice that’s earned us industry accolades and helped contribute to our double-digit bottom-line growth.

Our assurance team is responsible for reviewing low-level, high-assurance software in the finance, tech, defense, and blockchain industries. Our evaluations allow our clients to make informed decisions about risk to their systems, including how to minimize or mitigate security issues. Our team is comprised of experts in operating systems, compilers, and cloud infrastructure with a keen eye for applying research and developing custom tools to enhance our reach.

As an application security consultant, you will be part of a small, dynamic team that reviews highly trusted code, performs architecture reviews or threat models, and other types of security-focused analysis on behalf of our clients. You will provide value to our clients through your expertise and experience to assist the team in helping them find difficult issues. On any given day, you may be building cheats for DRM'd video games, exploiting elevation of privilege vulnerabilities in kernel drivers, or reviewing isolation primitives intended to contain the effects of exploitation.

You will work in collaboration with other assurance engineers to execute successful client projects and to build impactful tools. You will have opportunities to collaborate with our Research & Engineering team to help secure funding from government agencies for software security research that advances the state of the art, both within our team and the industry at large.

Between engagements, we apply our engineering skills to build custom tools to rapidly assess, exploit, or secure the code that we work with. You will also be given time for personal and professional development learning opportunities.

The base salary range for this role is $125,000-$250,000 DOE.
