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.
Role
Our growing team is directing the future of blockchain security. We review blockchain code and smart contracts for security vulnerabilities. Between engagements, we build custom tools like Manticore, Ethersplay, Slither, and Echidna to aid our process. Think of all of the security tools for x86 that you would have liked to have built yourself, but mature versions already existed. Few of those tools have been built yet for blockchain architectures. Join us to make a career-defining contribution. You will be at the forefront of blockchain security research. You will review smart contracts, blockchain infrastructure code, and decentralized applications for security vulnerabilities using a combination of manual static analysis and our tool suite. In your time between engagements, you will help improve our existing tooling and create new tools and analytics. Other practitioners will come to rely on your work. You will make a name for yourself in this nascent discipline.

An Insider's view of Trail of Bits

What’s the vibe like in the office?

Our offices are very easy going. Since half our employees are remote, we’re a remote-first company that just happens to have 20 people working in NYC. This gives us the benefit of a flexible remote culture but also have a place to get away from home and socialize with coworkers without rigid hours.

Ryan

Principal Security Engineer

How do you collaborate with other teams in the company?

Half of Trail of Bits is remote, so online collaboration and communication keeps us running. We make heavy use of Slack, Google Docs, Github, Trello, and video calls. Each project has its own Github repository and Slack channel, where most project communication occurs. A weekly video call provides high-level updates to the whole company.

Artem

Principal Security Engineer

What makes someone successful on your team?

My coworkers generally have deep knowledge in a technical area such as systems engineering, software vulnerabilities, cryptography, or something else and many are organized, good at communicating, and work well with a team. To be successful on the team I think it is best to be open minded, willing to learn new things, and easy to work with.

Sam

Senior Security Engineer

How would you describe the company’s work-life balance?

Trail of Bits makes it really easy for each of us to create the work-life balance that works for us as individuals. There is a lot of flexibility around when and where we work, and our tools and workflows make collaboration easy in a variety of settings.
