Why This Team
The Chief Information Security Office (CISO) is home to deeply talented colleagues that work to ensure the safety of Citi's clients', our revenue, our employees and our proprietary data. We manage information security as one end-to end program – one with a clear mandate and accountability. Our mission is a program that is fully anchored to modern control and architectural frameworks, is fully aligned with the enterprise architecture of the firm and is deeply integrated into the businesses and functions.
About the Role
Citi's Offensive Security and Vulnerability Management (OSVM) team is hiring practitioners who can run security assessments against AI systems and use AI-powered tools to make security testing faster and more effective.
The AI Offensive Security Analyst is an operational role on a team that runs penetration tests, vulnerability assessments, and Red Team adversarial evaluations across Citi's application portfolio. The AI dimension is twofold: you'll test AI systems as a target, and you'll use AI tools as part of how you work. We're looking for someone to help build the tools from scratch and who knows how to get the most out of them, knows their limits, and can operate in an environment where the right approach isn't always obvious yet.
What Makes This Different
The problems we're solving don't have playbooks yet.
- AI-driven vulnerability management. When frontier models can generate thousands of findings in a weekend, the bottleneck shifts from discovery to triage, verification, and remediation. We're building the pipeline that makes this sustainable.
- Security architecture for the AI era. Defining how a global bank deploys, monitors, and governs agentic AI — from standards and evaluation frameworks to production runtime monitoring.
- AI at scale, not in a lab. Citi has deployed AI tools to 180,000+ employees, equipped 30,000 developers with AI coding assistants, and is rolling out agentic AI capabilities firm wide. Securing that footprint and the platforms that underpin them is the job.
- Securing AI agents that can behave like insider threats. Frontier models can harvest credentials, escape sandboxes, and adapt when they detect monitoring. We're designing the containment architectures and runtime controls to operate them safely at enterprise scale.
- Real security engineering. This isn't a cyber seat where you'll spend your time in administration. You will be expected to understand the code, the architecture, the threats, and find solutions. You'll have the mandate and the backing to build something meaningful.
- Cyber Security Operations — Detection, triage, and response for a world where adversaries use AI to find and exploit vulnerabilities faster than traditional detection can keep up. Behavioral analytics for AI agents. Playbooks for AI-originated attack scenarios.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You'll Work On
- Testing AI applications and agents. GenAI applications, agentic systems, and LLM-backed products require testing that goes beyond standard web app methodology. Prompt injection, indirect injection, retrieval poisoning, tool misuse, sensitive data extraction, unsafe delegation, these are real attack classes with real business impact. You'll design and execute test cases for them.
- Using AI to work better. AI-assisted testing changes what's possible in a pen testing engagement: broader coverage, faster reconnaissance, automated validation of common vulnerability classes. You'll be expected to know how to use these capabilities effectively and to help the broader team adopt what works.
- Embedding security into development. Working with development teams and security engineers to make sure AI application assessments happen at the right points in the build process.
What We're Looking For
Security Testing Experience
- Practical experience running penetration tests or vulnerability assessments against web applications, APIs, or mobile applications. Alternatively, Red Team experience running adversary simulations as an operator.
- Familiarity with common security testing tools: Burp Suite, nuclei, nmap, or similar.
- Working knowledge of OWASP Top 10 and at least some exposure to OWASP LLM Top 10 or MITRE ATLAS.
- Ability to triage findings and communicate risk clearly to technical and non-technical audience.
AI Literacy
- Hands-on experience using LLM tools in a meaningful way, whether for security testing, security research, or your own workflows.
- Enough understanding of how LLMs work (context windows, tool use, RAG, agentic chaining) to reason about where they can go wrong.
- Familiarity with AI testing tools or frameworks, even from personal research or experimentation, is a real plus: Garak, PyRIT, PromptBench, Inspect AI, or equivalent.
General
- Comfortable working on problems that don't have a playbook yet.
- Can write clearly: test plans, findings reports, risk summaries.
- Curious about the security implications of AI systems, not just the hype around them.

Levels
- Assistant Vice President (C12 Mid - Senior Level): 5-7+ years. Own workstreams end-to-end with real autonomy. You'll go deep on problems that most organizations don't even know they have yet.
- Vice President (C13 Senior - Lead/Staff Level): 8-10+ years. Define technical approach, make architectural decisions, mentor others. The scope here is wider than most senior IC roles — you're not optimizing an existing system; you're designing ones that don't exist yet.
- Senior Vice President (C14 Lead/Staff - Principal Level): 10+ years. Set technical direction for a function and influence the firm's approach to AI security. If you've hit a ceiling elsewhere because the problem space isn't big enough, it's big enough here.
Why Citi, Why Now
- Real and urgent. Not an innovation lab. The threats are active, the work ships into production, and it protects one of the world's largest financial institutions.
- Technical teams. These are engineering-led functions. Small teams, high autonomy, minimal governance overhead. We build tools, ship code, and measure ourselves by what we deliver — not slide decks.
- Strong mandate. Executive sponsorship to move fast. You'll have the backing and resources to act on what you find.
- Unique scope. Very few organizations operate at this intersection at this scale. The solutions you build will influence how the industry responds.
Education
- Bachelor's degree in Computer Science, Information Security, Engineering, or equivalent practical experience.
- Master’s degree preferred.
