  • Design and build automated identity and access management (IAM), data encryption, and threat detection capabilities that function without manual intervention.
• AI Security Architecture & Integrity
  • Create technical baselines and security controls for AI-driven products, ensuring data model integrity and the security of training pipelines.
  • Build defenses against emerging AI-specific threats, such as prompt injection, model inversion, and data leakage, within both customer-facing and internal AI initiatives.
  • Conduct deep-dive technical reviews of AI architectures to ensure security is embedded into the foundation of every new model and automation project.
• Technical Leadership & Collaboration
  • Lead the response effort during active security incidents and provide expert analysis when called upon for internal investigations.
  • Partner with Engineering and SRE teams to engineer security directly into our Platform, CI/CD pipelines and Infrastructure-as-Code (IaC).
  • Provide technical mentorship to security and engineering teams, fostering a culture where security is viewed as an engineering challenge to be solved with code.
  • Ensure that all engineered solutions align with the broader enterprise security strategy.

Does this sound like you?
