Serve as the senior security authority for architecture reviews, technical guidance, and customer security engagements
Mentor engineers and champion secure design practices across the organization
Complete any additional tasks as they arise
Qualifications:
Bachelor’s degree or equivalent years of experience and/or certification in a related field

Deep knowledge of secure SDLC, threat modeling, OWASP, authentication, cryptography, API security, and mobile security
Experience securing products that process sensitive personal data while supporting privacy and regulatory requirements
Working knowledge of AI/ML and LLM security, including the secure adoption of AI development tools
Excellent written and verbal communication skills
Nice to Haves:
Experience with mobile SDK security, reverse engineering, and anti-tampering
Familiarity with data-intensive architectures and ML-driven products
Experience developing AI governance or secure AI adoption programs
Experience in telematics, IoT, connected vehicles, fintech, or other high-trust industries
Relevant certifications such as CSSLP, OSCP, or GWEB
