Application Security Engineer

Join our Software Assurance team!
The Trail of Bits Software Assurance team exclusively reviews low-level software for security issues. Our team is compromised of experts in operating systems, compilers, kernels, and embedded systems with a keen eye for applying research and developing custom tools to enhance our reach. Between engagements, we apply our engineering skills to build custom tools to rapidly assess, exploit, or secure the low-level code that we work with.

Role Description
As an application security engineer, you will be part of a small, dynamic team that reviews highly trusted low-level code on behalf of our clients. 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. Since our team is small, you will own everything that you do and play a key role in conceiving of new projects. You will collaborate frequently with our R&D 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.


  • Work directly with the leading industry teams to review their code and help secure their products
  • Design and implement solutions to difficult engineering and research problems
  • Collaborate with teammates to maintain and continually improve our existing security tools using modern software engineering practices
  • Develop new security tools


  • Experience with low-level software, either as an engineer or security researcher
  • Sufficient background in computer science to read relevant academic research
  • Familiar with the Git (and Github) workflow for software development
  • Proficient in one or more programming languages. In order of preference: C++, C, or Python. Bonus points if you have Haskell experience.
  • Strong debugging skills and/or experience with reverse engineering
  • Clear communicator and quick to participate in deep technical discussions
  • Highly self-motivated and able to drive new projects
  • Attracted to learning new technologies
  • Able to communicate complex technical material to clients and funding agencies
  • Adept at writing. We highly encourage all engineers to get regular face-time with clients, write company blog posts about their accomplishments, and deliver presentations to the technical community.
  • (Note: We prefer NYC for this position, but we will accept a remote position for the right candidate. We will also offer relocation assistance if you want to move to NYC.)


  • Our workforce is 50% remote. Many employees choose to work from home. As long as you keep delivering good work, we keep our hands off your personal style and let you manage your work day as you work best.
  • Liberal expense policy for acquiring the equipment and software that help you do your job. If we need hardware, we buy it. Everyone has rack space and corporate cards.
  • We can tell you exactly what projects you'll work on and the people you'll work with. If it's not what you want, no need to initiate a lateral transfer, we can shift your work without an issue.
  • Every year, we pay for the best in conference training, technical training, and managerial classes for our team. Everyone is encouraged to identify additional opportunities for personal professional growth.
  • We routinely highlight the work our employees are specifically paid to do via our blog, product offerings, and conference talks. We talk about more than just side projects.
  • We're at the forefront of a number of markets and have the internal expertise and the ambition to capitalize on those opportunities. See your work in use and valued by many others.
