Security Architecture & Threat Modeling: Perform vulnerability assessments, code reviews, and threat modeling for all new features and systems, focusing on the critical MES $\rightarrow$ WMS $\rightarrow$ OMS business process flow. Compliance Enforcement: Lead the implementation and auditing of security controls necessary for PCI-DSS compliance (for Payment module) and GDPR compliance (for user/tenant data handling). Access Control & Authentication: Implement and manage secure API authentication methods, including OAuth 2.0 and SAML, utilizing Authentik/Ory Kratos and leveraging PostgreSQL's Row-Level Security (RLS) for tenant isolation. Secrets & Encryption: Manage secrets and key rotation using Vault, define and enforce encryption protocols for data both in transit and at rest, and manage certificates via Traefik.

AI Agent Security You will be responsible for securing the emerging AI ecosystem. Agent Trust Framework: Establish security boundaries for the AI agent interfaces, ensuring agents (built with LangChain/AutoGen) operate within strict permissions when accessing supply chain data (WMS, OMS). Prompt Injection Prevention: Implement validation and sanitization techniques to mitigate prompt injection and data exfiltration risks in user-facing LLM interactions. Success Metrics & Career Path Performance will be measured by: Security Scorecard: Reduction in identified vulnerabilities from assessments and code reviews (SAST/DAST). Compliance Audits: Successful passing of regular PCI-DSS and GDPR audits. Incident Handling: Speed and effectiveness of security incident investigation and remediation. Mentorship Structure: Reports to the Solution Architect or Head of Technology, working closely with the development and DevOps teams to embed security into the CI/CD pipeline.
