AI Security Engineer
What We Are Looking For
We are looking for a professional responsible for ensuring security by design across AI solutions, agents, and supporting platforms, translating security requirements into practical controls and secure implementation patterns. You will contribute to identifying and mitigating AI-specific risks, strengthening security architecture and governance, and supporting secure deployments throughout the AI lifecycle, while collaborating with international technology, security, data protection, and business teams to ensure compliance with organizational standards and security best practices.
What You Will Do on a Daily Basis
As AI Security Engineer, you are the first line security engineering role within the Central AI team / AI Hubs.
Ensure that AI use cases, agents, and supporting platform components are built and operated securely by design and in line with the security framework.
Work hands-on with AI product, engineering, and platform teams to translate central security requirements into practical technical controls, implementation patterns, evidence, and delivery guardrails.
Work close to delivery, while maintaining a dotted line to Group Chief Information Security Officer (CISO) department to ensure alignment with client standards, security architecture principles, and control expectations.
Work closely with the Group AI leadership team, the Agentic Platform team, Group CISO, the Data Protection Office, and country IT and security leads.
Embed security by design across AI use cases, agents, and platform integrations, with strong controls for access, secrets, logging, monitoring, sandboxing, tool and API restrictions, and external integrations;
Translate group security policies and architecture into practical controls, reusable patterns, and guidance for AIteams, ensuring alignment with risk, third-party, supplier, and operational requirements;
Prepare security-gate evidence, drive remediation from reviews, and escalate unresolved control gaps, deviations, or delivery risks;
Address AI-specific risks such as prompt injection, data leakage, insecure tool use, excessive permissions, and weak auditability through hardening and secure deployment patterns;
Support due diligence and secure implementation for external AI vendors, models, orchestration components, and APIs, with the right safeguards for data protection and segregation;
Strengthen AI incident readiness through detection, logging, response scenarios, playbooks, exercises, and close collaboration with SOC and central security teams;
Scale secure AI delivery through reusable patterns, stronger hub capability, and lessons shared back into the groupwide security model.
Your Key Skills
Strong stakeholder management; able to challenge solution designs constructively and influence without full hierarchical authority;
Your Main Qualifications
7+ years in IT and cyber security, with at least some of that in transformation, digital or platform contexts;
Solid technical grounding in cloud security, identity and access management, application security and secure SDLC;
Working knowledge of AI/ML and Agentic AI security: prompt injection, data leakage, agent identity, tool-use risk, model supply chain. Familiarity with OWASP LLM Top 10, MITRE ATLAS and NIST AI RMF;
Experienced with threat modeling, risk assessment and security architecture for distributed systems;
Fluent English; an additional European language is a plus.
