Security Architect Consultant

Salary: £55,000 - 95,000 per year

Requirements:

• Security-first mindset; this is primarily a Security Architect role rather than a general cloud architect role.
• 5+ years of experience in information security, cloud security, and architecture roles.
• Strong knowledge of security governance, risk, and compliance frameworks, including ISO 27001, NIST CSF/800-53, NIS2, and DORA.
• Strong communication skills and ability to work with senior stakeholders.
• Experience mentoring teams or influencing security decisions.
• Experience designing cloud-native architectures focused on Google Cloud Platform (GCP), with hands-on knowledge of GCP security services and best practices.
• Experience architecting secure multi-project GCP setups and identity boundaries.
• Experience designing security for agent-based AI systems and LLM-integrated applications.
• Hands-on experience with AI/LLM security controls, including prompt security, model governance, secure APIs, and orchestration security.
• Expertise in AI-specific threat modelling.
• Strong cloud security background across AWS, Azure, and GCP.
• Experience with secure IAM, Zero Trust, network segmentation, data protection and encryption, and application and API security.
• Knowledge of SIEM, IAM, CASB, and container/Kubernetes security.
• Experience in Vibe coding and technologies similar to OpenClaw and Ollama.
• One or more of the following certifications: CISA, CRISC, CISM, or CISSP.
• Eligible to obtain UK SC clearance.
• Right to work in the UK.

Responsibilities:

• Translate business, data protection, and security requirements into practical architectural designs using industry frameworks such as NIST, ISO 27001, and CIS.
• Design and maintain cloud-native security architectures, with a focus on GCP architecture, security services, and secure workload design.
• Establish secure architectural patterns and standards across cloud platforms, including GCP IAM, VPC Service Controls, Cloud Armor, Confidential Computing, and 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, proportionate solutions.
• Design security architectures for agent-based AI systems, orchestration frameworks, tool-use agents, and multi-agent workflows.
• Implement AI/LLM security controls for model security, prompt security, APIs and orchestration, and data held in vector stores, embeddings, and retrieval services.
• Conduct AI-specific threat modelling, including assessment of model extraction and poisoning, hallucination-driven risks, sensitive data leakage, toxic output, and jailbreak attempts.
• Advise on secure, compliant, and privacy-aware integration of AI with cloud environments.
• Conduct risk assessments and threat modelling for cloud and AI systems, support incident response, and provide actionable mitigation strategies.
• Advise clients and explain cloud and AI security concepts to technical and non-technical stakeholders.
• Mentor teams on secure cloud design, AI security, and modern architecture practices.
• Participate in pre-sales and contribute to delivery collateral.
• 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 with governance standards such as ISO 27001, NIST 800-53/CSF, NIS2, DORA, and cloud security benchmarks.
• Conduct cloud and AI security architecture reviews, including cloud configuration reviews, GCP security posture assessments, and AI pipeline hardening.
• Evaluate and recommend security technologies for cloud, AI, identity, and data protection.
• Stay up to date with emerging threats, particularly in LLM, agentic AI, and GCP contexts.
