As a Security Architect, you will play a key role in designing and delivering secure, scalable, and compliant architectures for our clients, with a particular focus on Google Cloud Platform (GCP) and emerging Agentic AI systems Leveraging your strong cloud security and governance expertise, you will: Security Architecture • Translate business, data protection and security requirements into practical architectural designs leveraging industry frameworks (NIST, ISO 27001, CIS). • Design and maintain cloud native security architectures, with deep expertise in GCP architecture, security services, and secure workload design. • Establish secure architectural patterns and standards across cloud platforms, with specific focus on GCP IAM, VPC Service Controls, Cloud Armor, Confidential Computing, and secure workload segmentation. • Develop security design documentation, diagrams, and rationale aligned with business and compliance requirements. • Apply risk based and threat based approaches to recommend secure and proportionate solutions. Agentic AI & LLM Security Architecture You will be responsible for shaping security controls around emerging AI ecosystems, including: • Designing security architectures for agent based AI systems, including orchestration frameworks, tool use agents, and multi agent workflows. • Implementing AI/LLM security controls across: • Model security (input/output filtering, model guardrails) • Prompt security, adversarial prompt defense, prompt isolation • API & orchestration security, including secure agent tool use • Data security for vector stores, embeddings, and retrieval services • Performing AI specific threat modelling, including: • Model extraction & poisoning • Hallucination driven risk • Sensitive data leakage • Toxic output & jailbreak attempts • Advising on secure integration of AI with cloud environments, focusing on compliant, privacy aware design. Risk & Threat Management • Conduct comprehensive risk assessments and threat modelling for cloud and AI systems. • Support incident response, including issues involving AI driven systems and automated agents. • Provide actionable mitigation strategies for cloud and AI threats. Stakeholder Engagement & Technical Leadership • Provide expert guidance to clients, presenting complex cloud and AI security concepts to technical and non technical partners. • Mentor teams on secure cloud design, AI security, and modern architecture practices. • Participate in pre sales and contribute to delivery collateral Security Policy, Standards & Governance • Develop and implement cloud and AI security policies and standards. • Support compliance assessments and audits, including cloud specific controls and emerging AI regulatory frameworks. • Ensure alignment to governance standards such as ISO 27001, NIST 800 53/CSF, NIS2, DORA, and industry cloud security benchmarks. Technology Evaluation & Continuous Improvement • Conduct cloud and AI security architecture reviews, including: • Cloud configuration reviews • GCP security posture assessments • AI pipeline hardening • Evaluate and recommend security technologies for cloud, AI, identity, and data protection. • Stay up to date with new threats, especially in LLM, agentic AI, and GCP contexts. What experience youll bring: Required Core Profile • Security first mindset — this role is primarily for a Security Architect, not a general cloud architect. • 5 year’s experience in information security, cloud security and architecture roles. • Strong knowledge of security governance, risk and compliance frameworks (ISO 27001, NIST CSF/800 53, NIS2, DORA). • Strong communication skills and ability to work with senior stakeholders. • Experience mentoring teams or influencing security decisions. Required Technical Skills Google Cloud Platform (GCP) • Cloud native architecture design (GCP focused). • Deep hands on experience with GCP security services and GCP security best practices. • Experience architecting secure multi project setups and identity boundaries. Agentic AI Security • Experience designing security for agent based AI systems and LLM integrated applications. • Hands on experience with AI/LLM security controls (prompt security, model governance, secure APIs, orchestration security). • AI specific threat modelling expertise. Cloud & Security Architecture • Strong cloud security background across AWS/Azure/GCP. • Experience in secure design of: • IAM • Zero Trust • Network segmentation • Data protection and encryption • Application and API security • Knowledge of SIEM, IAM, CASB, container/Kubernetes security. • Experience in Vibe coding, as well as technologies experience similar to Openclaw and Ollama Certifications • One or more of: CISA, CRISC, CISM, CISSP (required). Other Requirements • Eligible to obtain UK SC clearance. • Right to work in the UK. Who we are: At NTT DATA, you have endless opportunities to think big, act bold and take ownership.
