Principal AI Security Engineer

Role 
This is a hands-on architecture role: deep research secure systems design and prototyping applied across product lines with minimal direction and broad latitude to set the technical agenda. You will set platform-wide direction for securing the AI development lifecycle define the security architecture agents and models operating within it and represent ServiceNows AI security point of view externally. Youll be a technical authority other engineers and other teams look to on emerging AI-specific threats working in close partnership with the AI security research team - drawing on their findings and feeding real-world attack surfaces back into their agenda. 

What youll do 

• Own the security strategy and architecture for our Agentic AI ecosystem LLMs and models across product lines 
• Lead threat modeling for the most complex and novel GenAI/agentic surfaces: cross-agent autonomy multi-agent tool orchestration and emerging attack classes not yet standardised in the industry 
• Set the architectural standard for securing model/RAG/data pipelines platform-wide including access-control and data-boundary models that other teams are expected to build against 
• Define what secure-by-design means for agentic systems at ServiceNow and drive adoption across engineering orgs 
• Represent ServiceNows AI security posture externally (standards bodies industry publications conferences) and internally to executive stakeholders 
• Mentor and technically guide engineers on AI-specific security work 

Qualifications :

To succeed in this role youll need:

• Bachelors / Masters degree or PhD in Computer Science or a related technical field specialisation in Security or AI/ML or an exceptional well-evidenced track record substituting for it 
• 10 years of software engineering experience including a track record of owning the architecture of complex systems at enterprise scale 
• A track record of setting technical direction beyond your own team - architecture or standards other teams adopted senior engineers youve levelled up and comfort operating where the problem isnt yet defined 
• 7 years in security engineering - network and systems security security protocols design reviews and threat modeling - with a focus on AI-specific work in recent years 
• Multiple demonstrated engagements threat modeling and/or securing LLM GenAI or agentic systems with evidence of platform-level or cross-team impact 
• Personal ownership of prompt injection / jailbreak defense guardrail architecture or AI red-teaming programs - ideally having built the program/methodology not just executed within one 
• Deep applied experience securing model RAG or data pipelines including having designed the access-control and data-governance model others build against 
• Fluency with the OWASP LLM Top 10 (or equivalent) to the point of extending critiquing or contributing to such frameworks - not just applying them 
• Deep hands-on experience with agentic AI frameworks (e.g. LangChain LangGraph) 
• Clear communication a collaborative default and a bias toward learning fast in a field that changes constantly 
• Bonus 
• Strong command of auth protocols (OAuth 2.0 OIDC PKCE API Keys) and agentic protocols (MCP A2A) including having designed identity/consent models for them 
• Built and open-sourced (or productized) security tooling/automation for AI systems now used beyond one team 
• Track record of CVEs top-tier publications or invited talks specifically in AI/ML or LLM security 
• Prior experience setting AI security strategy at a platform or company level not just a single product 
• 5 years of programming experience in Java or Python
