About the Role
As a Staff AI Enablement Security Engineer, you will be one of two senior security ICs focused on securing Trustly's AI transformation, including Claude, MCP implementations, and broader agentic AI tooling. You will define security standards and controls for AI systems, assess and mitigate risk with the AI Enablement team, and build tooling and frameworks to enable rapid AI adoption without compromising security.
Responsibilities
- Own security assessment and risk management for AI and LLM systems, including Claude, MCP server implementations, agentic workflows, and AI-assisted developer tooling.
- Define and implement security controls, access governance, and monitoring frameworks for AI systems, covering prompt injection, data leakage, model misuse, and agentic system abuse scenarios.
- Partner with the AI Enablement team to embed security from the start of AI feature development, conducting threat modeling, reviewing architectures, and advising on safe deployment patterns.
- Build and maintain tooling for AI-specific security monitoring, detecting anomalous model behavior, unauthorized data access, and policy violations in real time.
- Develop and maintain AI security standards, guidelines, and training resources for engineering teams.
- Stay at the leading edge of AI security research, tracking emerging attack vectors, defensive techniques, and regulatory developments.
Requirements
- 8+ years of security engineering experience, with at least 2-3 years focused on AI/ML security, LLM security, or security for data-intensive systems.
- Deep, hands-on understanding of the AI security threat landscape, including prompt injection, jailbreaking, data poisoning, model exfiltration, insecure agentic tool use, and MCP-specific attack surfaces.
- Strong security engineering fundamentals, experienced in threat modeling, secure design review, penetration testing, and building security monitoring infrastructure.
- Familiarity with MCP (Model Context Protocol) architecture, LLM orchestration frameworks, and agentic AI deployment patterns.
- Track record of operating at Staff+ IC scope, driving security decisions that span multiple teams and influencing architecture through technical credibility.
- Excellent communicator, able to explain novel AI security risks clearly to both technical and non-technical audiences and partner effectively with engineering teams.
