Who We're Looking For

Toyota Financial Services (TFS) Technology team is looking for a highly motivated person to fill a role as a Senior Cyber Security Engineer.

Your primary responsibility is to architect, deploy, optimize, and maintain the organization's Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platforms. Operating under the Information Security mandate, you will lead engineering efforts to ensure comprehensive log ingestion, detection fidelity, platform health, and automation capabilities that empower the Security Operations Center (SOC) and broader cyber defense teams.

We're looking for someone who thrives in a high-growth environment and brings deep technical expertise alongside strong engineering discipline, enabling you to build scalable, resilient security infrastructure that strengthens Toyota's detection and response posture.

What You'll Be Doing

SIEM Engineering & Platform Health: Lead the design, configuration, and ongoing maintenance of complex SIEM environments, including onboarding and managing diverse data sources, ensuring proper log parsing, normalization, and enrichment. Proactively monitor platform health, troubleshoot ingestion failures, and optimize storage and performance to maintain operational excellence.

SOAR Development & Automation: Design, build, and maintain SOAR playbooks and automated workflows that streamline alert triage, enrichment, and response actions. Continuously identify opportunities to reduce manual effort and accelerate mean time to detect (MTTD) and mean time to respond (MTTR) through intelligent automation.

Agent Deployment & Endpoint Telemetry: Lead the deployment, configuration, and lifecycle management of security agents across on-prem, cloud, and hybrid endpoint environments. Ensure consistent agent coverage, policy enforcement, and telemetry collection to maximize detection visibility across the enterprise.

Detection Engineering & Data Source Management: Develop and tune detection rules, correlation logic, and alerting thresholds within the SIEM to improve signal-to-noise ratio and detection accuracy. Partner with threat intelligence and SOC teams to translate emerging threats into actionable detection content. Manage the full lifecycle of data source integrations, including scoping, onboarding, validation, and ongoing health monitoring.

Scripting & Automation Development: Leverage scripting languages such as Python and PowerShell to build custom tooling, automate repetitive engineering tasks, develop API integrations, and enhance platform capabilities beyond out-of-the-box functionality.

Process Development & Standardization: Assist in the development and maintenance of standard operating procedures (SOPs), engineering runbooks, and documentation that streamline data source onboarding, platform maintenance, and incident support workflows. Continuously refine processes to improve efficiency and consistency.

What You Bring

3-5 years of experience in cyber security engineering, with hands-on expertise in SIEM administration and engineering, SOAR platform development, log management, data source onboarding, and security agent deployment and lifecycle management.

Strong understanding of log source types, parsing methodologies, data normalization techniques, and common log formats (e.g., Syslog, CEF, JSON, XML, Windows Event Logs).

Proficiency in scripting languages, particularly Python and PowerShell, with demonstrated ability to build automation, custom integrations, and engineering tooling.

Excellent communication skills with the ability to collaborate with and influence stakeholders at all levels, including SOC analysts, infrastructure teams, and leadership.

Experience in a regulated industry (e.g., finance, healthcare, government).

Proficiency in additional query and scripting languages (e.g., CQL, SQL, KQL, SPL, EQL, Yara, Bash).

Experience with security agent platforms such as CrowdStrike Falcon, or Halcyon.

Proficiency in AWS and Azure cloud environments, with a strong understanding of cloud-native logging, data flows, and access management.
