Job Description

Who We Are

Founded in 2012 by 3 expert hackers with no investment capital, Trail of Bits is the premier place for security experts to boldly advance security and address technology’s newest and most challenging risks. It has helped secure some of the world's most targeted organizations and devices. Our combination of novel research with practical solutions reduces the security risks that our clients face from emerging technologies. Our work helps drive the security industry and the public understanding of the technology underlying our world.

Cybersecurity preparedness is a moving target. Companies like ours are the tip of the spear in the fight against attackers. Our research-based and custom-engineering approach ensures that our client’s capabilities are at the forefront of what’s available. For companies and technologies that live and die by their security, a proactive, tailored approach is required to keep one step ahead of attackers.

Democratizing security information is essential. As part of our business, we provide ongoing informational support through blogs, whitepapers, newsletters, meetups, and open-source tools. The more the community understands security, the more they’ll understand why a company like ours is so unique and valuable.

Role

This role is for a security-focused software engineer who will design, build, and enhance security tools and frameworks across various contexts. You'll work on projects ranging from AI/ML security frameworks to compiler-based security tools, and everything in between, contributing to software that makes a real difference in the security landscape. Trail of Bits is AI-native, so you will have all the latest technologies at your disposal to help you establish an efficient workflow at your discretion.

As a Security Engineer, you are an individual contributor who receives tasking from project leads and delivers on technical milestones. Over time, you'll grow into leading major feature development, breaking down high-level objectives into manageable tasks, and presenting your work to clients. You'll be expected to pursue subject-matter expertise in areas that are part of Trail of Bits' core competencies and share what you learn through blogs, Lunch 'n' Learns, and publications.

Software development will primarily involve Rust, C++, and Python, with occasional work in Go and Java. You will typically work in teams of 2–4 people, all from remote locations. Technical leads guide the team's work, collaborating with you and other members to define responsibilities based on project needs, individual strengths, and team input. Frequent communication with team members and clients is essential to success, and writing about your work publicly is encouraged and incentivized.

We welcome applications from experienced professionals and talented recent graduates with relevant skills and interests.

• Secure Implementation : Implement secure CI/CD pipelines and integration with GitHub Actions.
• AI/ML Security Research : Contribute to AI/ML security research and tooling.
• Security Code Review : Evaluate and improve the security of existing software through code review and enhancement.
• Technical Communication : Communicate technical concepts effectively to team members, clients, and the broader security community. Write blog posts, participate in Lunch 'n' Learns and publications, and grow toward delivering client-side presentations.
• Technical Troubleshooting : Root-cause analysis and debugging on low-level technical issues.
• Project Execution : Interpret requirements, decompose tasks, and make engineering estimates. Work toward leading major feature development and moving projects toward their milestones.
