About the role

You'll define the security standards and controls for AI systems, work hands-on with the AI Enablement team to assess and mitigate risk, and build the tooling and frameworks that allow Trustly to move fast with AI without compromising security.
As a Staff AI Enablement Security Engineer, you will be one of two senior security ICs specifically aligned to Trustly's AI transformation - focused on securing Claude, MCP implementations, and the broader agentic AI tooling that Trustly is deploying internally and within its products.

Own security assessment and risk management for Trustly's 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 closely 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 across Trustly - making it easy for engineers to build with AI safely.
Strong security engineering fundamentals - experienced in threat modeling, secure design review, penetration testing, and building security monitoring infrastructure.
Excellent communicator - able to explain novel AI security risks clearly to both technical and non-technical audiences, and to earn trust with engineering teams as a partner rather than a gatekeeper.
To build the world's most disruptive payment network and redefine what the payment experience should feel like.

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.
Familiarity with MCP (Model Context Protocol) architecture, LLM orchestration frameworks, and agentic AI deployment patterns - you can reason about security at the level of individual tool calls and context windows.
Track record of operating at Staff+ IC scope - driving security decisions that span multiple teams, influencing architecture through technical credibility rather than authority.

ensuring these AI systems are built, deployed, and governed safely and in line with Trustly's risk posture.
