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

Trail of Bits’ Ecosystem Security Team is dedicated to improving the security and quality of engineering standards essential to the open-source ecosystem's longevity. Our team seeks a security-focused software developer to engage with Open Source communities and projects on behalf of our commercial, governmental, and non-profit clients. Among the many areas you may contribute are Open Source packaging, applied cryptography, authentication and authorization systems, and standard library and language development for major programming languages.

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. Software development will be primarily in Python, with frequent Rust and occasional opportunities to work in C, C++, Go, and Ruby. In addition to software maintenance and development, the role involves frequent creative and analytic challenges to design features and reviewing existing implementations with a critical lens. 

You will work with a remote team of 2-4 people 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 various clients throughout a typical year, and will engage with both clients and Open Source communities directly. Frequent communication with team members and clients is expected, and writing and presenting about your work publicly is encouraged and incentivized.

This position may be fully remote or based in our offices in Brooklyn. Conference attendance and travel to team offsites are encouraged but not required.

What You’ll Achieve

  • Contributing fixes and enhancements to large cross-platform codebases.
  • Designing and building solutions that balance performance, security, and functionality requirements.
  • Describe and explain technical concepts to clients, community, and co-workers.
  • Root-cause analysis and debugging on low-level technical issues.
  • Directly speaking daily with your team, typically within core hours, and coordinating asynchronously outside of core hours to organize tasking.
  • Interpreting customer requirements, decomposing tasks, and making engineering estimates.

What You’ll Bring

  • Previous experience with Open Source projects or communities. Experience leading or contributing significant features to Open Source projects is a plus.
  • 3+ years of experience in professional software development in one or more of the following domains: Open Source packaging, applied cryptography, authentication and authorization systems, or standard library and language development for major programming languages.
  • Proficiency in application and library development in Python, with systems and network experience as a plus. Experience in Go, Rust, C, and C++ is a plus.
  • Ability to work remotely and independently to set goals and find solutions.
  • Related development experience in security monitoring, security testing, security response, vulnerability research, cryptography engineering, or other security roles is a plus.
  • Composure speaking or writing directly to customers to give progress status reports and solicit feedback and new requirements.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
