Cloud Security Engineer

Company Overview

Docusign brings agreements to life. Over 1.5 million customers and more than a billion people in over 180 countries use Docusign solutions to accelerate the process of doing business and simplify people’s lives. With intelligent agreement management, Docusign unleashes business-critical data that is trapped inside of documents. Until now, these were disconnected from business systems of record, costing businesses time, money, and opportunity.

Using Docusign’s Intelligent Agreement Management platform, companies can create, commit, and manage agreements with solutions created by the #1 company in e-signature and contract lifecycle management (CLM).

As a Cloud Security Engineer focused on AI security, you will shape how we safely adopt AI by ensuring vendor-provided AI and ML solutions are thoroughly tested, hardened, and deployed securely. You’ll work closely with engineering and data science teams to go beyond compliance—actively probing for vulnerabilities, validating data handling, and building strong controls for third-party AI technologies. Your expertise will enable secure, responsible AI integration and help the business innovate with confidence while maintaining a strong security posture.

This position is an individual contributor role reporting to the Director, Platform Security.

• Inspect and validate how vendor AI/ML models handle sensitive data during ingestion and inference, including testing for data leakage, memorization, encryption, and tenant isolation
• Design and implement secure integration patterns for AI solutions in the cloud, such as API gateways and sandboxing, and partner with the red team to assess and strengthen input/output flows
• Build and maintain monitoring hooks and guardrails to detect model misuse, drift, anomalous output, or potential data exfiltration
• Implement technical safeguards and automation, including filtering layers, rate-limiting, DLP for prompts/responses, and synthetic data pipelines to minimize sensitive data exposure
• Collaborate with engineering, data science, and security teams to embed security into AI development and deployment workflows
• Partner with platform engineers and security architects to develop secure deployment patterns and reusable reference architectures
• Conduct threat modeling for AI/ML-specific attack surfaces (e.g., model inversion, membership inference, data poisoning, adversarial examples) and drive mitigations
• Support incident response and remediation for security events involving AI systems
• Document security processes, runbooks, and best practices for AI in the cloud
• Stay current with emerging threats and best practices in AI and cloud security
