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 reviews exclusively low-level, high-assurance software in the finance, tech, defense, and blockchain industries. Our evaluations allow our clients to make informed choices about risk to their systems, and what security-relevant modifications may be necessary for a secure deployment. Using our custom tools and unique expertise, we serve as a knowledgeable, dedicated adversary to identify the vulnerabilities that otherwise go undetected. In addition to providing recommendations that improve resistance to attack, we seek to deliver application-specific and industry-leading security engineering tools that embody the results of our assessments.

As a full time cryptography analyst you will be a part of a small, dynamic team that both engineers and reviews mission-critical cryptographic code. On any given day, you may be helping a client ensure their implementation of a novel cryptographic scheme is air-tight, collaborating with academics to bring their cutting edge ideas into reality, or developing new cryptanalysis tools. Since our team is small, you will own everything you do, and play a key role in conceiving of new projects. If you discover a gap in the open source cryptography community, we will help secure funding to develop it through our close relationships with academics and government research agencies. We are language agnostic, though we currently are using C++, Python, and Haskell.
