OverviewWho we're looking forToyota Financial Services (TFS) Information Security is seeking a passionate and highly motivated
Cyber Threat Emulation Lead to build the next generation of threat emulation capabilities for a global enterprise. 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 design and 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 help define the technical direction of the TFS threat emulation capability while remaining close 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 suited to an operator who enjoys researching emerging tradecraft, building tools, testing ideas in realistic environments, and turning successful prototypes into repeatable offensive security capabilities.
What you'll be doing- Design, build, and maintain end-to-end ML pipelines - from data ingestion and feature engineering to model training, evaluation, deployment, and monitoring
- Lead the integration of large language models into product features, including prompt engineering, retrieval-augmented generation (RAG), and agent-based patterns
- Select and apply the right approach for each problem: foundation models via Amazon Bedrock, custom training on SageMaker, classical ML, or hybrid approaches
- Take ownership of ML features from design through deployment - including testing, observability, and post-launch monitoring
- Participate actively in technical design discussions, contributing well-reasoned proposals and tradeoff analysis across ML architecture and tooling choices
- Debug and troubleshoot complex issues across ML systems - from training instabilities and data pipeline failures to inference latency and model drift
- Write clean, production-quality ML code and hold a high bar in code reviews
- Mentor junior and mid-level engineers through pairing, code reviews, and knowledge sharing on ML/AI topics
- Collaborate with Product, Data Science, and Front-End/Backend Engineering teams to deliver AI-powered features
- Identify and address data quality gaps, model reliability issues, and ML-specific tech debt proactively
What you bring- Bachelor's degree in computer science, Information Security, or related field, or equivalent experience
- 7+ years of progressive experience in Information Security with demonstrated experience conducting sophisticated adversary simulations and developing AI-assisted and agentic tooling to enhance, automate, and transform offensive security testing methodologies.
- Design and 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.
- Engineer safe 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, authorization boundaries, 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 attack techniques. Propose new research directions by applying relevant insights to the Toyota environment.
- Mentor other offensive security practitioners while remaining actively involved in research, tooling development, and engagement execution.
What you bring - Extensive experience in red teaming, adversary simulation, penetration testing, or offensive security.
- Demonstrated ability to plan and lead complex, end-to-end security engagements in an enterprise environment.
- Strong knowledge of modern attack techniques across identity, endpoints, networks, cloud platforms, applications, AI, and security infrastructure.
- Hands-on experience developing offensive security tooling, automation, or agentic workflows.
- Ability to communicate complex technical findings clearly to both technical and non-technical audiences.
- Sound judgment, integrity, and familiarity with the governance and operational safeguards required when conducting offensive security activity.
- Bachelor's Degree from an accredited institution, or equivalent experience
Added bonus if you have - Relevant security certification (CRTO, OSCP, OSWE, CISSP)
- Familiarity with security frameworks for attack (MITRE ATT&CK, Cyber Kill Chain), threat modeling (STRIDE, CVSS), and guidance (NIST, PCI).
- Understanding of regulatory issuances, such as CFPB, GLBA and SOX, and their applicability to technologies, applications and privacy laws (GDPR & CCPA) and other legal and compliance privacy and information security requirements.
- Advanced degree with a concentration in an IT related area.
