About the role

• AI Security Engineer strengthening the security of AI/ML pipelines and compliance at fintech company. Collaborating with data scientists and engineers to implement security controls across infrastructure.

Responsibilities

• Consult and review secure architectures for our AI systems – from in-house models to third‑party LLMs (incl. RAG, vector databases, APIs, and integrations into our products and internal tools).
• Conduct AI-specific threat modeling and security reviews across the ML lifecycle (data → training → deployment → monitoring).
• Perform security testing / red-teaming of LLM and ML systems (e.g. prompt injection tests, jailbreaks, exfiltration and data-leakage tests).
• Work closely with data scientists, Machine Learning engineers, platform engineers and Compliance & IT Security to define and implement concrete controls in pipelines, infrastructure and applications.
• Own and support AI risk assessments, and help write/review policies, standards and governance documentation for AI use.
• Translate EU AI Act, financial-services regulation and relevant standards into practical technical and process controls.
• Help define monitoring, logging and incident response for AI/LLM systems, including misuse and data-leak detection.
• Collaborate with Legal, Compliance and Procurement on AI vendor selection, risk assessments and contract reviews.

Requirements

• Demonstrable experience in Artificial Intelligence/Machine Learning security in a production context – not just general cybersecurity.
• Practical knowledge of LLM-specific risks, such as: prompt injection and jailbreaks data leakage and sensitive information exposure model inversion, membership inference supply chain risks in AI tooling and models.
• Solid understanding of the ML lifecycle and typical MLOps setups (data pipelines, training, evaluation, deployment, CI/CD, monitoring) and where to place security controls.
• Experience designing or reviewing secure architectures for AI/LLM systems, including: API security and authentication/authorization secrets management (API keys, tokens, credentials) isolation of tenants/contexts and access control for data sources & vector stores protection of sensitive data in prompts, logs and training data.
• Experience working side-by-side with data scientists or ML engineers – you have credibility in technical rooms and can challenge design decisions constructively.
• Ability to read Python code and basic ML pipelines and to build small scripts/tools (e.g. for automated tests, log analysis, or prototype guardrails).
• Background in risk assessment and in writing or reviewing policy and governance documentation.
• Familiarity with relevant AI standards and frameworks, such as: ISO 42001 OWASP LLM Top 10 NIST AI RMF OECD AI Principles.
• Understanding of EU AI Act obligations and how they apply to a fintech / financial services context, with the ability to map them to concrete controls.
• Strong grasp of data protection and privacy-by-design in AI (data minimisation, pseudonymisation/anonymisation, retention and deletion of training and log data)
