Make your impact within a rapidly growing Fintech Company
We are looking to hire a Sr. Staff AI Security Engineer to lead the secure deployment and operation of AI and ML systems across the company. This role moves beyond traditional perimeter security to address the unique vulnerabilities of Large Language Models (LLMs) and automated orchestration layers. Your mission: provide a secure foundation—gateways, orchestration layers, and tool ecosystems—that enables developers to innovate at pace while maintaining a robust security posture.
You’ll partner with platform ,engineering and IT teams as a builder and enabler rather than a gatekeeper, embedding security into the AI development lifecycle by default and shaping how BILL navigates the AI threat landscape.
Secure AI Architecture & Infrastructure: Design and implement secure gateways that act as controlled entry points for AI requests, ensuring all interactions are authenticated and logged. Build orchestration layers that enforce security policies (rate limiting, content filtering) across multiple AI models and providers. Integrate security controls into developer tool ecosystems so security is baked in by default—highly available, scalable via infrastructure as code, and never a performance bottleneck for production AI applications.
Adversarial Research & Red-Teaming: Own and stand up a formal AI red-teaming practice to identify vulnerabilities before they reach production. Research and simulate advanced attack vectors including prompt injection, jailbreaking, adversarial suffixes, model extraction, model poisoning, training data leakage, and AI supply chain compromise. Systematically document findings and deliver clear remediation paths to engineering teams.
Strategic Leadership: Own the long-term AI security roadmap, aligning technical goals with BILL’s business mission. Act as the primary subject matter expert advising senior leadership on AI risk. Mentor engineers across the organization to raise BILL’s collective security IQ.
