Toyota Financial Services (TFS) Technology is seeking a highly experienced and outcome‑driven Lead Security Architect to define, govern, and advance a threat‑informed, data‑centric security architecture across enterprise platforms and business services.

This role is accountable for embedding Data‑Centric Threat Modeling (NIST SP 800‑154) into the architecture lifecycle ensuring that security decisions are driven by how data is created, processed, stored, and exposed, rather than relying solely on perimeter or technology‑centric controls. The ideal candidate will operate as a senior technical authority, influencing design decisions, enforcing architectural standards, and driving measurable improvements in control effectiveness across TFS environments.

• Own and operationalize Data‑Centric Threat Modeling (NIST SP 800‑154) across application, cloud, and enterprise architectures
• Identify threats, attack paths, and control gaps based on data flows, sensitivity, and business impact
• Integrate threat modeling into solution design, architecture reviews, and delivery pipelines
• Drive consistency through standardized methodologies and tooling (e.g., Threat Modeler, Irius Risk)

• Establish and govern security architecture standards, patterns, and reference models aligned to TFS policy and risk tolerance
• Lead architecture design reviews and provide binding security decisions for critical initiatives
• Ensure solutions align to Zero Trust principles, least privilege access, and data protection requirements

• Translate threat models and architectural assessments into actionable risk insights for executives and stakeholders
• Support risk acceptance, exception handling, and architectural trade‑offs with clear business impact articulation
• Identify control gaps and redundancies across security tooling; recommend optimization and rationalization strategies

• Collaborate with engineering, infrastructure, data, and application teams to embed security early in the development lifecycle
• Influence third‑party and vendor design reviews using threat‑informed architecture criteria, not just checklist‑based assessments
• Align with risk and compliance teams to ensure regulatory expectations (e.g., financial services controls) are integrated into design

• Move beyond artifact review (e.g., SOC 2, ISO 27001) to assess real‑world control effectiveness against identified threats
• Correlate assurance evidence with actual attack scenarios and data exposure risks
• Drive continuous improvement in architecture based on evolving…
