Job description

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.

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.

AI Security Specialist
AI models can now autonomously discover and exploit zero-day vulnerabilities in production software — and we're building the defensive capability to match. We're hiring across four CISO teams working at the intersection of AI and cyber security.

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.

What You'll Work On
Depending on your background and interests, you could join one of four teams:

• Offensive Security & Vulnerability Management — AI-assisted pen testing at a scale previously impossible. Automated exploit validation. Bridge the gap from "AI found a vulnerability" to "the application team has a PR to fix it."
• AI & Emerging Technology Security — Define how the bank deploys AI safely. Security architecture and assurance for new implementations, plus building the next generation of AI-powered tools for our CISO colleagues. Test new models at the cutting edge of creation and influence.
• Cyber Security AI Services — Own the AI products CISO depends on in production — security assurance, cyber security operations, governance and controls, vulnerability assessment. Keep them reliable, evolve them fast.
• 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.

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.

Qualifications

• Strong record of technical leadership and architecture on complex, novel systems.
• Deep expertise building and scaling agentic/LLM systems with rigorous evaluation, guardrails, and production reliability.
• Demonstrated depth across both domains - able to lead credibly in offensive security and detection/SecOps.
• Advanced certs (OSWE, OSCE) and/or recognized AppSec/detection contributions (open source, research, conference talks) (nice to have)
• Experience defining AI governance/model-evaluation frameworks and addressing AI-security threats at scale (nice to have)

We offer
By joining Citi, you will not only be part of a business casual workplace with a hybrid working model (up to 2 days working at home per week), but also receive a competitive base salary (which is annually reviewed), and enjoy a whole host of additional benefits such as:

• 27 days annual leave (plus bank holidays)
• A discretional annual performance related bonus
• Private Medical Care & Life Insurance
• Employee Assistance Program
• Pension Plan

• Special discounts for employees, family, and friends
• Access to an array of learning and development resources
