Full description
Design and build autonomous red-team systems and agents that discover, exploit, and report vulnerabilities in apps and digital infrastructure at scale. Develop agentic workflows leveraging coding agents, RAG, domain knowledge repositories, and tool-integrated agents to accelerate the development, evaluation, and continuous improvement of red-team agents and systems. Design reusable data processing frameworks, canonical data models, and data contracts that accommodate evolving red teaming and business require Lead architectural decisions across cloud data platforms, distributed compute engines, data lakes, streaming and batch processing, and analytical serving systems, balancing data freshness, correctness, performance, and cost. Streamline red-team agent development through automated pipelines for code reviews, failure triage, root-cause analysis, and operational knowledge discovery. Establish governance and quality guardrails for red team agents including automated testing, correctness validation, security reviews, and production-readiness checks. Embody our culture and corporate values.
