Who We're Looking For Toyota Financial Services (TFS) Technology team is looking for a highly motivated person to fill a role as a Forward Deployed AI Security Lead within the Security Intelligence Engineering organization. You'll own the intelligence platform end-to-end: from API integrations with enterprise security tools, to a cross-source correlation engine, to an agentic AI layer that autonomously triages security findings at scale, to dashboards that deliver actionable intelligence to multiple security teams. You'll operate at the intersection of security operations, AI/ML engineering, and cloud platform development - embedding directly with security team leads to understand their workflows and building AI systems that transform them. This role follows the Forward Deployed Engineer model: you embed with internal security teams as your customers, deeply understand their operational reality, and build production systems that deliver measurable outcomes.

Responsibilities

• Embed directly with security team leads across multiple functions to deeply understand their workflows, tools, and pain points
• Lead discovery sessions to identify high-value automation opportunities - translating security operations problems into AI-solvable technical specifications
• Own the structured intake process: prioritize requests by cross-team impact and risk reduction value, communicate capacity and timelines transparently
• Design and build multi-agent architectures using managed AI services - autonomous triage agents, cross-source correlation agents, and team-specific specialist agents
• Implement RAG systems over a centralized security data lake for natural language threat hunting and investigation
• Build prompt engineering patterns, evaluation frameworks, and feedback loops that continuously improve agent accuracy
• Design a model routing layer that directs each task to the optimal model based on complexity, latency, and cost
• Implement centralized token usage monitoring and cost controls for leadership visibility
• Own agent observability: monitoring for drift, hallucination detection, accuracy degradation, and failure mode identification
• Architect human-in-the-loop controls and guardrails ensuring agents operate safely within defined boundaries
• Design and build API connectors to enterprise security tools (EDR/XDR, cloud security, API security, identity, vulnerability management)
• Architect the cross-source correlation engine that links findings across endpoint, cloud, identity, and network data
• Define and evolve the data lake schema and ingestion pipelines for security telemetry
• Build and maintain dashboards serving multiple security teams with team-specific views
• Set engineering standards, code review practices, and architectural patterns a
