• Stakeholder engagement – Maintain positive client and supplier relationships, communicate commercially in multidisciplinary teams and support incentivisation and social value objectives.
• Technical commercial knowledge – Apply sector‑specific understanding of construction costs, supplier markets and procurement routes within complex programme interfaces.

Expected: bachelor’s degree in a relevant discipline; valid driving licence; working toward or holding ICAS chartership.

Desirable: formal procurement, commercial or dispute resolution training and prior water sector AMP experience.
