• Translating regulations, standards, and guidance into clear, defensible evaluation and audit procedures.
• Designing foundations for consistent, high-quality audit execution, including datasets, workflows, and reusable analysis frameworks.
• Taking a long‑term view on emerging risks, regulatory shifts, and industry trends, and helping evolve the organisation’s AI assurance approach.
• Anticipating future data and analytical capabilities needed as products and regulations mature.
• Establishing principles for interpreting results, handling uncertainty, and communicating limitations clearly and responsibly.
• Supporting high‑stakes stakeholder conversations with technical authority and contextual insight.
• Contributing to documentation, external‑facing explanations, and thought leadership content to build credibility and trust.

What we’re looking for:

• 5+ years of senior‑level experience
• Expertise in either Responsible AI, Psychology or HR Analytics
• Comfort working with ambiguity and open‑ended analytical problems
• A rigorous, evidence‑driven mindset with a focus on defensibility and clarity
• A collaborative, high‑ownership approach to work
• Awareness of evolving regulations, standards, and industry expectations
