Who we're looking for
Toyota Financial Services (TFS) Technology team is looking for a motivated and detail-oriented person to fill a role as a Security Engineer. In this role, you will support the engineering, maintenance, and improvement of the organization's vulnerability management and threat intelligence automation platforms. Working under the Information Security team, you will assist with Key Risk Indicator (KRI) reporting pipelines, CrowdStrike API/NG-SIEM integrations, Google Threat Intelligence (GTI) data pipelines, Qualys vulnerability data tuning, and CI/CD test automation that supports the Security Operations Center (SOC) and broader cyber defense teams.
We're looking for someone who is eager to learn, enjoys solving technical problems, and is interested in building a strong foundation in security engineering within a collaborative environment.
What you'll be doing
KRI & Vulnerability Trend Reporting: Build and maintain automated pipelines that calculate Key Risk Indicator (KRI) scores, track newly introduced and remediate vulnerabilities and maintain historical snapshot/environment-change tables that feed executive dashboards.
Threat Intelligence Pipeline Development: Design, build, and maintain end-to-end data pipelines that pull Indicators of Compromise (IOCs), campaigns, threat reports, CVEs, and TTPs (Tactics, Techniques, and Procedures) from Google Threat Intelligence (GTI), including associating related threat objects (e.g., linking IOCs to campaigns and reports).
CrowdStrike Integration: Develop and maintain CrowdStrike API integrations, including API manager classes, Identity Protection scripts (e.g., account disablement tracking), and NG-SIEM worker/scheduler processes that support automated bulk searches of security event data.
Qualys Vulnerability Management: Assist with tuning Qualys API-based data pulls (e.g., posture/policy compliance filtering, host list detection) to improve data accuracy and reduce noise in vulnerability reporting.
Database Engineering: Design and maintain database models to store vulnerability and threat intelligence data (IOCs, campaigns, reports, TTPs, KRI history, and their associations), ensuring data is structured for efficient querying and reporting.
Concurrency & Performance Optimization: Build multi-threaded/concurrent data processing solutions to improve the speed and reliability of large-scale API data pulls and database writes, including batch-commit strategies for efficient performance.
CI/CD & Test Automation: Build and maintain GitHub Actions workflows for automated testing, code coverage reporting, and pre-commit hooks (linting, formatting) to improve code quality and reduce regressions across the security engineering codebase.
Scripting & Automation Development: Use Python to build automation scripts, API integrations, and export utilities that support threat intelligence operationalization and vulnerability tracking, reducing manual analyst workload.
Process Development & Documentation: Assist in creating and maintaining SOPs, runbooks, and documentation for platform support, pipeline configuration, data models, and troubleshooting workflows.
What you bring

• Experience with Python, including scripting, concurrent/multi-threaded programming, and ORM frameworks such as SQL Alchemy.
• Familiarity with relational databases (e.g., PostgreSQL) and designing/maintaining structured data pipelines.
• Basic understanding of threat intelligence concepts such as Indicators of Compromise (IOCs), TTPs, and threat campaigns/actors.
• Exposure to CI/CD tools such as GitHub Actions, Pytest, and code quality tooling (pre-commit, Pylint).
• Strong problem-solving skills, willingness to learn, and ability to work collaboratively in a team environment.
