  • Troubleshoot manufacturing challenges and drive resolution during commercialization.
  • Serve as a primary technical liaison with contract manufacturing partners.

Sensory & Product Performance
  • Design and execute sensory evaluations focused on taste, texture, mouthfeel, and overall product experience.
  • Analyze sensory data and identify opportunities for product improvement.
  • Translate consumer and panel feedback into formulation enhancements.
