Member of Technical Staff (Security)

Role overview Research and test security tools that assess how well AI agents identify vulnerabilities in real software. You’ll combine hands-on vulnerability research with benchmark design and product testing, working closely with research and engineering colleagues in a small, high-ownership team.

Responsibilities - Expand vulnerability research on open-source software, including work alongside a founder. - Create realistic benchmarks to measure agent performance on security tasks. - Observe agents operating on real systems and use findings to improve their effectiveness. - Assess products and internal systems for security weaknesses. - Share research findings with engineering to inform product development.

Requirements - Demonstrated strength in at least two relevant areas; the listed criteria are flexible rather than strict prerequisites. - Understanding of reachability analysis or taint tracking. - Knowledge of web application vulnerabilities, demonstrated through security competitions or credited vulnerability discoveries. - Experience presenting technical security research at conferences. - Experience using both conventional security tools and language-model-based tools in research.

Benefits and work setup - Full-time, hybrid role with teammates in several international locations; in-person coworking is optional. - Payroll arrangements support employees or contractors in multiple countries, and coworking memberships are provided. - Optional European team offsites take place about every two months. - Competitive salary, meaningful equity, and health, vision, and dental insurance.
