Director of Information Security & IT leading H1's security - first technology operations. Working at the intersection of data, AI - technology, and healthcare to improve patient outcomes.
About the role
- AI Security Engineer at Cross River designing secure AI systems to protect customer data and meet regulations. Focusing on scalable guardrails and tools for innovative financial technology.
Responsibilities
- Design enterprise AI guardrails across Azure and AWS (e.g., Azure AI Studio/Azure OpenAI, Amazon Bedrock/SageMaker): content filtering, PII redaction, prompt/response validation, and policy enforcement services.
- Implement data minimization controls for GenAI/RAG workloads: context filtering, least‐privileged retrieval, document-level ACL enforcement, vector store hardening, and secure token/secret handling.
- Threat model AI systems (apps, agents, RAG, fine-tuning pipelines) using frameworks like STRIDE and the OWASP Top 10 for LLM Apps; define misuse scenarios (prompt injection/jailbreaks/data exfiltration) and build mitigations.
- Build monitoring and telemetry: privacy-preserving prompt/response logging, sensitive-data detection, safety/eval dashboards, drift/abuse signals, and incident hooks into our SIEM.
- Integrate AI security into the SDLC: reusable libraries, pre-commit checks, CI/CD gates, policy-as-code, and secure-by-default reference architectures for product teams.
- Evaluate third‑party AI vendors and internal apps: security reviews, data residency and retention requirements, SSO/SCIM integrations, DPA/TPRM inputs, and continuous control testing.
- Partner across Security, Data, Privacy, and Engineering to map AI controls to FFIEC, SOC 2, and PCI DSS; document control evidence for audits.
- Lead/participate in AI red‑teaming: automated jailbreak/prompt‑injection tests, safety benchmarks, purple‑team exercises, and response playbooks for AI incidents.
- Enable the org with concise guidelines, examples, and training on safe AI development and usage.
Requirements
- 5+ years in Security Engineering/AppSec/Cloud Security (or similar), including 1–2+ years securing AI/ML or data‐intensive systems (GenAI preferred).
- Hands‐on experience with AWS and/or Azure and modern app stacks (Python/TypeScript, REST/gRPC, containers/Kubernetes, IaC such as Terraform).
- Practical understanding of LLM attack surfaces (prompt injection, data leakage via tools, training/fine‑tune poisoning, model supply chain) and mitigation patterns.
- Familiarity with identity and access for AI workloads (OAuth2/OIDC, service principals, role tokens, PIM), and secure secret management/KMS.
- Experience implementing observability/telemetry and routing findings to SIEM; comfort balancing privacy with traceability.
- Ability to translate controls into developer-friendly libraries, docs, and CI/CD checks; strong written communication in English and Hebrew.
- Comfort working in a regulated environment and mapping controls to frameworks (FFIEC, SOC 2, PCI DSS).
Benefits
- Flexible hybrid work model: three days a week at our Jerusalem office
- Monthly wellness reimbursement – from therapy to gel manicure, it's up to you
- Full Keren Hishtalmut, private health and dental insurance
- Volunteer days, donation matching, Yoga and Pilates
- A supportive, collaborative culture that puts our people first
