Job Description  :

• Contribute to developing strategic OT/IACS Cybersecurity initiatives, technology projects and security programs across the Chevron Enterprise globally  

• Contribute to the design and review of secure IACS/OT network architectures and data flows including communication between applications, ports, protocols, and services  

• Contribute to the creation of OT/IACS cybersecurity guardrails to ensure all OT architectures, solutions and technologies across the Chevron enterprise are built using a secure-by-design methodology  

• Utilize industry standards and frameworks (e.g., NIST-800-53/82, IEC-62443, MITRE ATT&CK / D3FEND), to identify capabilities and technologies to provide enhanced cyber defenses in diverse scenarios  

• Support OT cybersecurity initiatives by partnering with Product Owners, delivering cybersecurity engineering solutions, and advancing tools such as Axonius, Tenable. 

• Develop OT cybersecurity research project proposals. Research, test, and/or lead proof-of-concepts for new and emerging OT technologies.   

• Lead cybersecurity assessments for Chevron’s Business Unit IACS designs/installations and/or emerging technology OT solutions to determine criticality rankings and risk gaps  

• Lead OT cybersecurity assessments including detailed design reviews, system and component descriptions, identification and selection of evaluation criteria, network topology reviews, mapping of data flows to ports, protocols, and services tables  

• Provide security recommendations for normally unmanned facilities where Industrial Internet of Things (IIoT), optimization, “Big data” analytics, and OT integration with the Cloud are being considered.  

• Provide recommendations and plans to mitigate identified issues from OT cybersecurity risk assessments, IACS Vulnerability assessments, and OT Pen tests  

Required education
