Role

Trail of Bits seeks a Software Security Engineer within our Research & Engineering team to work at the intersection of security research and practical software development. You will design, build, and enhance security tools and frameworks across various contexts, working on projects ranging from compiler-based security tools to AI/ML security frameworks.

On any given day, you might implement security-focused software tools, contribute to open-source projects, analyze complex security challenges, or develop practical solutions for clients. Working in small teams of 2-4 people, you'll collaborate with researchers, security experts, and clients while building impactful tools.

You will have opportunities to pursue your interests while delivering practical security solutions, with software development primarily involving Rust, C++, and Python, with occasional work in Go and Java. Success is measured through impact, focusing on building tools others can use and build upon, rather than paper metrics.

What You’ll Achieve

Tool Development: Design and implement security-focused software tools and frameworks, contributing to open-source security projects and developing internal tools for practical security solutions.

Security Analysis: Analyze complex security challenges across the stack, from low-level systems to application frameworks, evaluating and improving existing software through code review and enhancement.

Implementation: Develop secure CI/CD pipelines with GitHub Actions integration, contributing to AI/ML security research and tooling with a focus on practical, deployable solutions.

Client Collaboration: Work directly with industry-leading teams to understand complex security challenges and implement effective solutions through deep technical analysis and recommendations.

Technical Communication: Effectively communicate technical concepts to team members, clients, and the broader security community, with opportunities to write about your work publicly.

What You’ll Bring

Development Expertise: Strong software development skills with experience in Rust, C++, and/or Python, with occasional need for Go or Java knowledge and demonstrated ability to quickly learn new programming languages, frameworks, and technologies. Experience with multiple programming languages and paradigms is highly valued.

Security Knowledge: Understanding of computer security principles, common vulnerability classes, and experience with secure development practices and building secure software. Prior contributions to open-source security tools or frameworks and participation in CTF competitions or security challenges would be beneficial.

Technical Capabilities: Root-cause analysis and debugging skills for low-level technical issues, ability to interpret requirements, decompose tasks, and make engineering estimates. Understanding of low-level systems (including memory management and OS internals), compiler technology, program analysis, or binary analysis is advantageous.

Advanced Domain Knowledge: Experience with AI/ML systems and associated security challenges is valuable, as is experience developing commercial-grade software used by the public. Experience reading, writing, and implementing academic papers demonstrates the depth of knowledge we value.

Collaboration Skills: Ability to work independently and as part of a remote team with strong written and verbal communication skills for frequent team member and client interactions. Experience in public speaking is a plus.

CI/CD Experience: Familiarity with CI/CD pipelines and automated testing methodologies for secure software development.
