You'll drive the secure deployment of cutting-edge AI solutions across Operational Technology (OT) and Industrial Control System (ICS) environments, influencing the future of AI in critical infrastructure. This is an onsite position in Houston, TX, offering hands-on experience shaping cybersecurity standards and architecture for AI initiatives in a highly collaborative, enterprise-scale setting.
Responsibilities
- Define and implement cybersecurity requirements and reference architectures for AI workloads within OT/ICS environments.
- Develop secure deployment patterns for AI systems across edge, on-premises, PCN/DMZ, disconnected, and cloud-connected environments.
- Establish zones, conduits, trust boundaries, and segmented networks for AI-enabled OT systems.
- Set security controls governing read/write access, autonomous actions, and human-in-the-loop AI controls.
- Design and enforce identity, monitoring, and runtime visibility requirements for non-human identities, including AI agents and service accounts.
- Conduct threat modeling and cyber assurance reviews for industrial AI use cases, identifying risks such as data poisoning, model manipulation, and protocol misuse.
- Align OT AI security controls with industry frameworks (IEC 62443, NIST SP 800-82, NIST AI RMF, MITRE ATLAS).
- Drive development of OT AI cybersecurity guardrails and contribute to Chevron's Security for AI strategy and roadmap.

- In-depth knowledge of OT/ICS architectures, network segmentation, zones/conduits, PCN/DMZ, and industrial protocols (Modbus, DNP3, OPC UA).
- Proven experience designing or reviewing cybersecurity architecture for critical infrastructure or industrial environments.
- Strong understanding of AI/ML security risks, including Generative AI and AI agents.
- Experience defining security requirements for machine identities, service accounts, APIs, or non-human identities.
- Hands-on expertise in security monitoring, detection engineering, incident response, and runtime visibility within OT.
- Familiarity with IEC 62443 and NIST SP 800-82.
- Ability to translate complex risks into actionable architecture standards and technical guardrails.
Preferred Skills
- Experience securing AI/ML workloads in OT, ICS, manufacturing, energy, or utilities.
- Familiarity with NIST AI RMF, MITRE ATLAS, and AI Security Posture Management (AISPM).
- Experience with autonomous/agentic AI, edge AI, computer vision, or disconnected/air-gapped environments.
- Proficiency in developing reference architectures, security standards, or enterprise guardrails.
- Strong written communication with a track record of producing technical documentation and roadmaps.
Benefits
- Work with a leading global energy company at the forefront of AI-enabled industrial transformation.
