Degree in Food Science, Biochemistry, Dairy/Meat Science, or a related field is highly preferred.
Fundamental understanding of protein structure, from the primary amino acid sequence through secondary, tertiary, and quaternary structures.
Strong understanding of how proteins behave in real food systems and during processing.
Deep expertise in protein characterization and protein-based ingredient interactions, including protein-protein interactions, protein-carbohydrate interactions, and protein-lipid interactions, and the analytical and modeling approaches used to study them.
Experience with adjacent ingredient fundamentals and their interaction, specifically to proteins, dairy, and non-dairy, and/or enzymes.
Strong grasp of food industry trends, consumer preferences, and regulatory requirements.
Experience with pilot plant trials, ingredient functionality testing, and cross-functional product development.
Excellent problem-solving skills and the ability to translate science into practical solutions.
Excellent communication and collaboration skills, including the ability to work effectively with cross-functional teams and engage non-technical audiences.
Demonstrated ability to prioritize and manage complexity, navigate ambiguity, and think creatively.

Nice To Haves

Additional experience or ability to translate knowledge to plant-based proteins is a plus.

Responsibilities

Apply your knowledge of protein functionality (e.g., emulsification, gelation, water binding) to improve food texture, stability, and performance.
Lead formulation and application work using dairy and meat proteins in products such as sauces, snacks, desserts, cheese, dairy-based beverages, and meat systems. Additional experience or ability to translate knowledge to plant-based proteins is a plus.
Partners with Product Development, Process Engineering, Nutrition, Regulatory, and Marketing teams to support product innovation from concept through commercialization.
Evaluate new protein ingredients and technologies from suppliers and academic partners; identify opportunities for joint research and technology scouting.
Support scale-up and manufacturing by addressing protein-related processing challenges.
Develop and maintain a deep understanding of the protein ingredient landscape, including emerging technologies (e.g., enzymatic modification, fermentation-derived proteins, hybrid protein systems).
Design and execute experiments to generate data on protein behavior under various processing and storage conditions.
Maintain detailed documentation of experimental protocols and results.
Prepare and file Invention Disclosure Forms (IDFs) to document novel technologies and support patent filings; conduct patent landscape analyses to assess freedom-to-operate, competitive activity, and whitespace opportunities, and translate findings into actionable R&D and innovation strategy.
Stay current on protein science, food regulations, and consumer trends to inform application strategies and maintain relevant external network.
