• Develop contracting playbooks, training materials, and scalable legal workflows.

• 6+ years PQE; UK or EU qualified (US-qualified also considered).
• Significant experience drafting, reviewing, and negotiating a wide range of commercial agreements (in-house or private practice).
• Confident engaging with counterparties across the UK, US, and Europe.
• Experience supporting RFPs/tenders, ideally including public sector and academia.
• Ability to streamline contracting processes and develop playbooks, templates, and training.
