Food /Protein Chemistry Scientist

Just Food Company • Emeryville, CA

1d • $135,000 - $158,000 • Onsite

About The Position

We are looking for a Food /Protein Chemistry Scientist to help advance the science behind our food and protein platforms. This is a highly hands-on role for someone who combines deep technical expertise in protein chemistry and food science with strong experimental judgment and practical problem-solving skills. You will design and execute studies to better understand protein structure, extraction, functionality, stability, and performance — and translate those findings into better ingredients, products, and processes. We are looking for someone who doesn't simply execute experiments. You should be comfortable working through ambiguous technical challenges, developing hypotheses, determining what to test next, and turning complex data into clear recommendations that move the work forward.

Requirements

• PhD in Food Science, Protein Chemistry, Biochemistry, Chemistry, or a closely related field, with a minimum of 2 years of relevant industry experience; or a Master’s degree with 5+ years of relevant industry experience.
• Strong hands-on experience with protein extraction, purification, characterization, functionality, and/or process optimization, ideally within food or food-adjacent applications.
• Strong understanding of protein structure-function relationships and how processing conditions influence protein behavior and performance.
• Direct experience with multiple protein characterization techniques such as differential scanning calorimetry (DSC), fluorescence spectroscopy, rheology, SDS-PAGE, or related analytical methods.
• Demonstrated experience designing and executing multi-variable experiments using DOE, factorial designs, or other systematic optimization approaches.
• Working knowledge of sequence- and structure-based bioinformatics tools such as BLAST, structure alignment tools, or ProtParam-type sequence analysis.
• Strong analytical judgment and ability to synthesize complex experimental data into clear conclusions and recommendations.
• Excellent experimental discipline, documentation, and attention to detail.
• Ability to communicate effectively with both highly technical and non-technical audiences.
• High degree of independence and self-direction. You are comfortable determining the next question or experiment rather than relying on a predefined protocol.
• Must be authorized to work in the United States without current or future employer sponsorship.
• Must verify identity and eligibility to work in the United States and complete the required Form I-9 upon hire.

Nice To Haves

• Experience working specifically with plant, alternative, or novel proteins.
• Experience translating laboratory findings into food applications or scalable manufacturing processes.
• Hands-on experience with cell cultivation, fermentation, or fermentation-derived proteins.
• Experience working across both fundamental protein science and applied food/product development.

Responsibilities

• Design and execute systematic studies to understand and optimize protein extraction, yield, functionality, and performance.
• Develop and optimize novel extraction and processing approaches, balancing protein functionality, food-grade requirements, scalability, and downstream processing constraints.
• Develop and apply analytical methods to understand protein structure-function relationships and identify drivers of functional performance.
• Apply protein chemistry, food science, and computational approaches to troubleshoot technical challenges and improve protein functionality and stability.
• Evaluate protein performance through processing, formulation, storage, and shelf life, translating findings into actionable recommendations for product and process development.
• Independently interpret complex or ambiguous results, develop hypotheses, and determine the most valuable next experiments.
• Partner closely with Product Development, Process/Manufacturing, Quality, and other technical teams to translate laboratory findings into practical, scalable solutions.
• Maintain rigorous experimental documentation and clearly communicate findings, conclusions, and recommendations to technical and non-technical stakeholders.

Benefits

• Equity
• Up to 100% employer-paid medical, dental, and vision coverage (up to 90% for dependents)
• Flexible time off
• 9 Holidays + company closure between Christmas & New Years
