Security Architect Consultant

What you'll be doing:

Hybrid variable permanent - London or Birmingham 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 isolationAPI & orchestration security, including secure agent tool useData 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 reviewsGCP security posture assessmentsAI 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 you'll 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.
