Sr. Applied Scientist, AI & AGI Security

We are seeking a Senior Applied Scientist to lead research and development of novel security validation and monitoring techniques for AI systems at scale. You will own and contribute to four critical workstreams:

• 1. Real-Time Agent Monitoring
• Design and implement scientific approaches for continuous behavioral analysis of AI agents in production—detecting anomalous actions, prompt injection exploitation, and policy violations in real time.

• 2. MCP Server Validation
• Develop novel validation frameworks to assess the security posture of Model Context Protocol (MCP) servers, including input sanitization verification, tool-use authorization boundaries, and data exfiltration detection.

• 3. AI-Enabled Application Validation
• Invent and deliver scalable methodologies for security testing of AI-enabled applications, including adversarial robustness evaluation, safety guardrail bypass detection, and trust boundary verification.

• 4. AI Asset Discovery & Inventory
• Research and build scalable techniques to automatically discover, identify, and catalog all AI-enabled applications and services across the company—maintaining a comprehensive, continuously updated database of AI assets.

• Key job responsibilities
• Invent
• •Identify and frame new research challenges in AI security where problems are ill-defined and require novel scientific paradigms at the product level.
• •Drive the team's scientific agenda for agent monitoring, validation research, and AI asset discovery; propose new initiatives and secure leadership buy-in.
• •Publish research results at peer-reviewed internal and external venues (e.g., USENIX Security, IEEE S&P, NeurIPS, ICML security workshops) when appropriate.
• •Articulate key scientific challenges of current and future AI security threats and present interventions to address them.
• •Make trade-offs between short-term tactical security needs and long-term research investments.

• Implement
• •Lead the design, implementation, and successful delivery of scientifically complex security solutions into production—both brand new systems and evolutions of existing ones.
• •Write significant portions of critical-path code for detection models, validation engines, and asset discovery / classification systems.
• •Independently assess and select appropriate technologies (e.g., streaming inference frameworks, graph-based anomaly detection, NLP-based service classification, code/traffic analysis for AI fingerprinting) for production systems.
• •Drive adoption of best practices in scientific methodology and software engineering across the team; provide insightful peer reviews of code, design, and architecture artifacts.
• •Deliver solutions that are inventive, maintainable, scalable, and extensible.

• Influence
• •Autonomously drive discussions with security engineers, product managers, and scientist peers across multiple teams.
• •Build consensus on larger cross-team security initiatives and factor complex efforts into independent workstreams.
• •Proactively identify and resolve endemic problems, including areas where current security tooling limits innovation of partner teams.
• •Actively recruit, mentor, and develop other scientists; provide technical assessments for promotions.
• •Contribute to the broader internal and external scientific communities as a subject matter expert in AI security.
