Job Description
We are looking for an AI Security Engineer to secure our AI-driven systems, including LLM-based applications, machine learning models, and AI-enabled automation tools.
This role will focus on identifying, assessing, and mitigating security risks across the AI lifecycle — from model development and training to deployment and runtime monitoring.
The ideal candidate combines strong security engineering experience with a deep understanding of machine learning systems and emerging AI-specific threats (e.g., prompt injection, model poisoning, data leakage, adversarial attacks).
Key Responsibilities:
AI/ML Security Architecture
  • Design and implement security controls for AI/ML systems across development, training, and production.
  • Secure LLM integrations, RAG pipelines, and AI APIs.
  • Conduct threat modeling for AI systems and data pipelines.
  • Define secure-by-design patterns for AI-powered features.

  • AI Threat Detection & Mitigation

  • Identify and mitigate AI-specific threats: prompt injection and jailbreak techniques, model poisoning and data contamination, adversarial attacks, training data leakage, insecure model serialization, excessive permissions in AI agents.
  • Develop guardrails, content filters, and output validation mechanisms.
  • Implement monitoring for anomalous AI behavior.
  • Secure Development & DevSecOps

  • Integrate AI security checks into CI/CD pipelines.
  • Perform security reviews of ML code and AI-related infrastructure.
  • Secure model registries and artifact storage.
  • Collaborate with other engineers and platform teams to enforce security standards.
  • Data Protection & Compliance

  • Ensure AI systems comply with: GDPR and data privacy regulations, financial industry regulatory requirements, implement controls for sensitive data used in training and inference, perform AI risk assessments aligned with internal risk methodology.
  • Governance & Policy

  • Contribute to AI security standards and internal policies.
  • Define AI risk classification and control frameworks.
  • Support security reviews for new AI initiatives / tools.
  • Required Qualifications:
  • 3–5+ years in software engineering, ML engineering, or application security
  • Hands-on experience with AI/ML systems — LLMs, NLP models, or similar.
  • Python proficiency for automation and scripting.
  • Experience working with Claude Code.
  • Strong understanding of cloud platforms: AWS, Azure, or GCP
  • Experience with API security, Docker, Kubernetes
  • Knowledge of AI-specific security risks and mitigations
  • Experience conducting threat modeling and risk assessments.
  • Preferred Qualifications:
  • Familiarity with RAG architectures, vector databases, ML pipelines (MLflow, Kubeflow, SageMaker).
  • Experience in fintech or regulated environments.
  • Knowledge of AI governance frameworks (EU AI Act, NIST AI RMF, ISO/IEC 42001).
  • Experience with AI red teaming.
  • Background in cybersecurity or application security (OWASP, Secure SDLC).
  • Soft Skills:
  • Strong analytical and problem-solving skills.
  • Ability to translate technical risk into business impact.
  • Able to explain AI security risks and mitigations to non-security teams.
  • Cross-functional collaboration with ML, data, and product teams.
  • Clear documentation and communication skills.
  • What you will get in return:
    Competitive Salary: We believe great work deserves great pay! Your skills and talents will be rewarded with a salary that makes you feel valued and motivated.
