This is a hands-on technical opportunity for an experienced offensive security practitioner who wants to develop new capabilities, not simply operate an existing red team program. You will execute sophisticated adversary simulations while building AI-assisted and agentic tooling that changes how offensive security testing is performed. You will have the opportunity to experiment with emerging attack techniques, develop custom tooling, orchestrate multi-stage attack workflows, and apply artificial intelligence to increase the speed, adaptability, and scale of threat emulation.

This role will contribute tothe TFS threat emulation capability while remainingclose to the keyboard.Working across the global TFS Group companies, you will touch complex enterprise, cloud, identity, application, and AI-enabled environments, to challenge real security controls and work directly with defenders to measurably improve them.

This role is suitedto an operator who enjoys researching emerging tradecraft, building tools, testing ideas in realistic environments, and turning successful prototypes into repeatable offensive security capabilities.

Whatyou'llbe doing

• Execute end-to-end red team and control test engagements that reproduce realistic adversary behaviors across identity, endpoint, network, application, cloud, container, and AI-enabled environments.

• Develop custom offensive security tooling and reusable attack capabilities rather than relying exclusively on commercial testing platforms.

• Build AI-assisted and agentic workflows for reconnaissance, attack-path discovery, campaign planning, vulnerability analysis, payload development, control validation, and post-exploitation emulation.

• Leverage and tune multi-agent systems capable of adapting attack-paths, interpreting results, and coordinating multi-stage adversary simulations at speed and scale.

• Integrate large language models with internal telemetry and threat intelligence to prioritize and drive offensive security workflows.

• Test AI-enabled applications and agentic systems, including model interfaces, retrieval pipelines, tool integrations, authorizationboundaries, data flows, and indirect prompt-injection paths.

• Work directly with SOC analysts, detection engineers, incident responders, and threat intelligence analysts to break, tune, retest, and improve security controls through purple team exercises.

• Stay current on global cyber trends and attacktechniques. Propose new research directions by applying relevant insights to the Toyota environment.

• Mentor other offensive securitypractitioners while remaining actively involved in research, tooling development, and engagement execution.
