Sr. Applied Scientist, AI & AGI Security

Description

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.
