• Provide clear, commercially focused legal advice to internal stakeholders.
• Develop contracting playbooks, training materials, and scalable legal workflows.
• Collaborate closely with Sales and other key stakeholders to support commercial aims and risk mitigation.
• Coordinate work with external counsel when needed.
• Advise on broader commercial matters as they arise, including marketing, IP, and consumer issues.

What you’ll bring to the role

• 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.
