What are we looking for?

We are looking for an AI Security Engineer with:

  • More than 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.
  • Strong stakeholder management; able to challenge solution designs constructively and influence without full hierarchical authority.
  • Pragmatic, outcome-driven, biased for delivery; resilient under ambiguity.
  • Fluent English (an additional European language is a plus).

We Value

  • A Prior security responsibility in a multi-country, federated environment (logistics, retail, financial services).
  • Hands-on exposure to LLM and agent platforms (e.g. Azure AI, Anthropic, OpenAI, Vertex, LangChain) and MLOps tooling.
  • CISSP, CISM or equivalent.
  • Experience contributing to or running AI red-teaming exercises.

What do we expect from you?

  • 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 AI teams, 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.
