- Own security architecture for protecting sensitive data and supporting privacy and regulatory requirements
- Define security architecture and guardrails for AI-powered products and AI development tools
- Own the Product Security roadmap, including technology strategy, prioritization, and risk-based decision making
- 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
- 7+ years of experience in security with deep expertise in application and product security architecture
- Proven ability to set technical direction and drive security initiatives through influence in a highly autonomous role
- Strong software engineering foundation with experience reviewing code and system architecture across web services, APIs, and mobile platforms
- 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
