Job Description
The Head of Responsible AI and Assurance will provide senior leadership for Defra’s approach to responsible, trustworthy and auditable AI, ensuring AI-enabled solutions are adopted in a way that is safe, lawful, ethical and operationally sustainable.
The role exists to enable Defra to realise value from AI while maintaining public trust and meeting HMG’s expectations for robust governance and proportionate assurance of digital and data activity. It establishes and operates the department’s AI assurance approach, including assurance standards, risk tiering, and decision routes for high-risk AI use cases.
The postholder will work with senior stakeholders across DDTS, Data Protection, Legal, Commercial and Delivery Group leads. They will also act as an escalation point on AI risk and assurance and ensure a consistent approach across delivery portfolios.
The Role Will Broadly
- Set and maintain Defra’s responsible AI and AI assurance framework, tools and associated standards.
- Lead assurance mechanisms (risk tiering, reviews/clinics, evidence requirements, and decision routes).
- Provide expert leadership on ethical, sustainable and societal considerations in AI adoption and use.
- Ensure AI solutions include appropriate controls for auditability, transparency, evaluation, validation and monitoring.
- Enable delivery through clear, proportionate guardrails rather than creating barriers.
