COMPANY BACKGROUND / CULTURE

Nuritas’ mission is to improve the lives of billions, and our vision is to provide the hero ingredient in everyday products. We are transforming the discovery of bioactive ingredients using AI, deep learning, and genomics to unlock peptides from natural sources like plants and food.

Our proprietary platform, Magnifier, uses advanced machine learning and our extensive dataset of molecules to identify natural peptides with specific health benefits. We optimize these molecules for stability and scalability, ensuring they perform in real-world applications. Our plant peptide ingredients include PeptiStrong® for protein amplification and muscle health, and PeptiSleepTM for improving deep and REM sleep. Through our ingredients, customers can create better products that are truly differentiated in addressing consumer needs.

Founded in 2014 by Dr. Nora Khaldi, the company has built the world’s largest peptide knowledge base and formed high-profile partnerships with companies like Nestle, Mars, and Sumitomo Corporation. Its team, diverse in nationality and gender, is driven by innovation and passion to bring nature’s benefits to the world.

We are proud to be an equal opportunities employer, creating an inclusive culture where every voice matters.

We are seeking a highly motivated and detail-oriented Technical Scientist to join our R&D team. The successful candidate will be responsible for executing and supporting all laboratory activities related to protein hydrolysis, process optimisation and functional ingredient development. This includes conducting trials, performing analytical assays and contributing to pilot plant operations.

The role requires strong scientific and technical expertise, excellent record-keeping and the ability to collaborate effectively across multidisciplinary teams including R&D, Supply Chain, Operations, Quality, Regulatory and Sales.

This is an excellent opportunity to contribute to pioneering work in the field of functional food ingredients within a growing and innovation-driven environment. The successful candidate will play a key role in bridging laboratory research and commercial application, supporting the company’s continued growth and scientific excellence.

Key Responsibilities

Conduct protein hydrolysis experiments at bench and pilot plant scale.
Perform routine analysis such as degree of hydrolysis, and protein concentration assays
Operate laboratory and pilot-scale equipment, including bioreactors and bench-scale spray dryers.
Support and execute pilot plant trials, ensuring accurate -implementation and documentation of all activities.
Maintain meticulous records of trials, data, and results, ensuring traceability and compliance with internal quality standards.
Conduct shelf-life studies on ingredients and products, analysing stability and performance over time.
Collaborate closely with cross-functional teams to support the transition of lab-scale developments to commercial-scale applications.
Contribute to the development and optimisation of up- and downstream processing for protein hydrolysates.
Ensure adherence to all health, safety, and regulatory standards within the laboratory environment.

Qualifications & Experience

Bachelor’s or Master’s degree in Food Science and Technology, Biotechnology, Biochemistry, or a related discipline.3–5 years’ experience in process optimisation and functional ingredient development, ideally within the food, biotech, or nutraceutical industries.
Demonstrated experience in protein hydrolysis; postgraduate research or industrial experience in this area is highly advantageous.
Proven track record in the development and commercialisation of functional ingredients, particularly peptides and protein hydrolysates.
Strong analytical, problem-solving, and troubleshooting skills.
Excellent data recording, documentation, and report-writing ability.
Proficiency in Microsoft Office Suite (Excel, Word, PowerPoint).
Highly organised, methodical and self-motivated with strong attention to detail.
Excellent communication and presentation skills
Strong teamwork skills, with a collaborative approach to working across functions.

Key Projects

Develop and optimise upstream and downstream processes for protein hydrolysates.
Execute protein hydrolysis and analytical assays at both bench and pilot scales.
Operate and optimise bioreactor and spray dryer systems.
Conduct shelf-life and stability studies of ingredients and finished products.
Maintain comprehensive trial records to support process validation and product development.
