AI Assurance Practitioner in Portsmouth

We are seeking a specialist AI Assurance Practitioner to implement, operationalise, and deliver a proactive, risk-based AI Assurance Framework across complex, high-consequence operational and enterprise systems. As our client transitions toward continuous, proportionate AI governance, you will provide critical subject matter expertise to embed prescriptive AI assurance across the full capability lifecycle. Working directly with engineering and delivery teams, senior project owners, and enterprise risk authorities, you will ensure AI-enabled systems are safe, secure, ethical, and operationally effective.

Due to the secure nature of this project, you will need to hold SC or DV clearance (minimum requirements: 5 years of residency in the UK & British Nationality).

Key Responsibilities

• Policy Implementation & Operationalisation: Translate overarching defence AI policies, standards (such as JSP 936), and industry frameworks (e.g., ISO 42001) into practical, repeatable assurance processes, checklists, templates, and guidance.
• Intake, Triage & Risk Categorisation: Manage the intake and registration pipeline for emerging AI initiatives, assessing system context, consequence, and novelty to determine proportionate tiers of assurance.
• AI Ethical & Risk Assessments: Guide multidisciplinary delivery teams through system boundary definition, hazard identification, ethical impact assessments, control design, residual risk scoring, and formal risk ownership.
• Technical Evidence & Model Review: Interrogate AI system specifications, data provenance, training pipelines, model documentation, algorithmic bias assessments, and data sufficiency to constructively challenge incomplete evidence.
• Specialist Assessment Coordination: Scope and coordinate deeper technical assurance for high-risk capabilities, including model evaluations, adversarial robustness/red-teaming, and cyber/safety stress tests.
• Governance, Escalation & Reporting: Maintain the central AI assurance risk register, elevate critical residual risks through established governance boards, and compile evidence to support senior leadership assurance statements.
• Process Alignment & Integration: Align AI assurance workflows with established digital delivery mechanisms, Secure by Design (SbD) frameworks, safety cases, and technical test/trials pathways.
• Enduring Capability & Knowledge Transfer: Deliver coaching, guidance, and upskilling to internal delivery teams and emerging assurance personnel to build sustainable in-house AI evaluation capability.

Essential:

• Security Clearance: Valid UK National Security Vetting SC Clearance with eligibility and willingness to undergo Developed Vetting (DV).
• Defence AI Standards: Practical working knowledge of UK Defence AI standards and policies (specifically JSP 936 or equivalent regulated sector frameworks).
• AI Risk & Governance: Proven track record conducting AI impact assessments, ethical risk evaluations, and establishing controls for algorithmic models and automated decision-making.
• Technical Understanding of AI/ML: Grounded technical comprehension of machine learning architectures, data pipelines, model drift, data provenance, validation metrics, and performance evaluation.
• Assurance & Compliance Frameworks: Exposure to emerging international AI standards and frameworks, such as ISO/IEC 42001, NIST AI RMF, or IEEE standards.
• Stakeholder Management: Demonstrated ability to act as an independent challenger while collaborating effectively across diverse teams: data scientists, systems engineers, safety managers, legal advisors, and senior operational stakeholders.

Desirable:

• Experience with Secure by Design (SbD), system safety engineering, or defence test and evaluation processes.
• Hands‑on experience planning or executing model red‑teaming, adversarial testing, or synthetic data verification.
• Background working within UK Defence, national security, aerospace, or other high‑reliability regulated sectors.
