Trail of Bits

About Trail of Bits
Trail of Bits helps secure the worldโ€™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. Itโ€™s a practice thatโ€™s earned us industry accolades and helped contribute to our double-digit bottom-line growth.

Join our Engineering Services Team

Our engineering services team works closely with commercial customers in tech, defense, and finance on quick-response feature development, security infrastructure deployment troubleshooting, security vulnerability triage and remediation, and bug fixes. We adopt and support the best of open-source security software for our work, and regularly contribute enhancements to these projects as a result.
We enjoy knowing that our work is making an impact and helping to secure organizations all over the world and that we are delivering improvements to software used by thousands. We regularly interact with the open-source community, collaborate with its many talented contributors, and share the opportunity to hear directly from real users.
The primary responsibilities of this role are developing security-focused software and engaging with commercial clients / open-source communities. The focus areas are endpoint security, security agents, host telemetry, security engineering, vulnerability triage and remediation, build systems, logging pipelines, and associated security infrastructure.
Software development will be primarily in C++. The role involves not just maintenance development, but also frequent creative and analytical challenges to design features and review existing implementations with a critical lens.
This is an engineering position, where the focus is to integrate novel features into production systems. It does not involve direct operations like service monitoring and maintenance.
You will typically work in teams of 2-4 people, all from remote locations, in roughly 4-8 week development cycles. Technical leads will assign responsibilities to you and other team members, and you will develop proofs of concept, prototypes, and enhancements to existing tools in support of a project's goals. You will have opportunities to work for a variety of clients throughout a typical year.
Frequent communication with team members and clients is essential to success, and writing about your work publicly is encouraged and incentivized.
This is a fully remote position (travel rarely required).
The base salary range for this role is $125,000-$200,000 DOE.
