AI Security Researcher/Research Engineer
Research and engineer security measures for LLM-powered web agents and chatbots, including adversarial testing, secure architectures, model evaluation, and security-focused training. The role requires strong Python and ML expertise, AI security experience, and preferably a computer science Ph.D.
About the job
Responsibilities
- Design and execute adversarial evaluations to uncover failure modes in LLM-powered web agents and chatbots, including prompt injection, tool abuse, and data exfiltration.
- Analyze model behavior, including internal thoughts, to understand and forecast security risks in frontier models.
- Develop and prototype security-focused training and fine-tuning techniques.
- Augment web agents with security principles such as information-flow control, privilege control, and contextual security.
- Partner with engineering, privacy, machine learning, and cryptographic researchers to translate findings into product changes, tests, and measurable security improvements.
- Help define security strategy and policy for building and responsibly releasing web agents, with a focus on user protection.
Requirements
- Demonstrated experience with secure AI, including prompt-injection attacks and security guardrails.
- Strong publication record in AI security, ML security, or closely related areas.
- Track record of shipping products and features in a fast-moving environment.
- Strong Python coding skills and familiarity with ML frameworks such as PyTorch or JAX.
- Experience training, fine-tuning, and evaluating large language models.
- Deep familiarity with large language models and web agents, including how they work and are trained.
- Experience applying security principles such as information-flow control and access control/least privilege.
- Demonstrated ability to bring clarity and ownership to ambiguous technical problems.
- Ph.D. in computer science highly preferred; exceptions may be considered for candidates with industry experience.
Nice-to-haves
- Knowledge of AI-system pipelines and security evaluation.
- Open-source projects focused on security or privacy.
- Experience with confidential computing and ZKP/SMPC protocols.
- Ph.D. in computer science from a top-tier school.
- Strong publication record in premier systems, performance, or machine-learning venues.
- Industry work experience.
