AI Security Engineer

As an AI Security Engineer at Fireblocks, you own the security lens on AI across the company and its platform. You track the fast-moving external AI threat landscape, assess how AI is being used by developers, corporate users, and through procured tools, and architect the controls, infrastructure, and tooling that keep that usage secure. This is a hands-on, builder-focused role where you design, implement, and operate solutions working closely with Security, R&D, and other stakeholders.

What you'll do

• Track new developments, capabilities, and attack techniques in the AI space and translate them into concrete risks for Fireblocks
• Build and maintain a living threat model for AI usage across the company, covering the platform, internal tooling, and third-party AI services
• Analyze how AI is used across Fireblocks in the platform, by developers such as those using coding assistants, by corporate and business users, and through AI tools brought in via procurement
• Assess the configuration and security posture of AI systems and tools in use, and identify and prioritize gaps
• Design and propose new tooling, configurations, and projects that reduce AI-related risk
• Architect and implement solutions end-to-end, partnering with engineering teams where needed
• Build and operate the AI security infrastructure that makes AI usage across Fireblocks secure by default
• Research open-weight model implementations for use in security workflows
• Deploy open-weight models to support incident response teams in investigating and responding to security incidents in real time

What you bring

• 3+ years of experience in AI and ML, with hands-on exposure to both
• 3+ years of experience in engineering or R&D roles
• Strong knowledge of cloud infrastructure, particularly AWS, and how AI workloads run in production
• Strong understanding of AI and ML system architecture including model deployment, inference infrastructure, RAG, pipelines, and agent frameworks
• Hands-on experience configuring and rolling out leading AI tools and platforms for a broad internal audience
• Experience working with open-weight or open-source models in production or research settings
• A track record of designing, shipping, and operating security tooling or infrastructure end-to-end, not just advising on it
• Excellent communication skills and the ability to work independently while coordinating closely with Security, R&D, and other stakeholders

Nice to have

• Familiarity with AI security frameworks such as OWASP Top 10 for LLM Applications, NIST AI RMF, or MITRE ATLAS
• Experience with SOC and IR tooling, threat intelligence, or offensive security
