• Manage sensory evaluations and consumer testing (qualitative and quantitative), analyse data, and provide actionable recommendations.
• Prepare and approve technical documentation (ingredient specifications, formulation briefs, and finished product) and develop process control documents in collaboration with quality and operations teams.

• Lead scale‑up trials across European sites, including co‑packers, by defining objectives, developing Design of Experiments plans, capturing critical data, and aligning cross‑functional teams to optimise product performance.
• Direct full‑scale production trials to validate process robustness, confirm commercialisation strategies, and ensure seamless transfer from development to manufacturing.
• Troubleshoot manufacturing, pilot plant, and laboratory processes using data‑driven approaches to resolve technical challenges that directly impact delivery timelines, product quality, or customer acceptance.

• Provide hands‑on technical leadership to the Product team, setting priorities based on customer and commercial criticality and fostering collaboration to deliver reliable outcomes.
