Core Responsibilities

Primary Functions

Lead end-to-end formulation and product development projects for dairy categories (fresh milk, UHT, cream, yogurt, cheese, butter, milk powder), creating robust recipes, ingredient specifications and pilot-plant protocols that meet targeted sensory profiles, cost targets and shelf-life requirements.
Design, run and analyze pilot plant trials to validate new formulations and process changes; translate pilot-scale parameters into manufacturing-scale process instructions including pasteurization, homogenization, separation and drying parameters.
Optimize manufacturing processes to improve yield, reduce waste and lower production cost while maintaining or improving product quality, working closely with production engineers and site operations to implement process parameter changes and control strategies.
Develop and execute shelf-life and stability studies (microbiological, chemical, physical and sensory) with controlled sampling plans and statistical analysis to establish commercial shelf-life and storage recommendations.
Implement and maintain HACCP programs and prerequisite GMP controls for dairy product lines; author and update hazard analyses, critical control point documentation and monitoring plans to ensure regulatory compliance.
Lead microbiological control programs, including environmental monitoring, finished product testing and corrective actions; interpret microbial data and advise on process controls and sanitation practices to mitigate contamination risk.
Conduct sensory evaluation sessions (triangle tests, descriptive analysis, consumer acceptability panels) and convert sensory feedback into actionable formulation or processing changes to meet target consumer profiles.
Troubleshoot on-line manufacturing issues (off-spec product, process deviations, fouling, filtration problems) using root-cause analysis (5 Whys, Ishikawa) and lead CAPA plans across cross-functional teams until resolution.
Prepare technical dossiers, production instructions, specification sheets and master records for new and reformulated products; ensure traceability of ingredient sources, allergen declarations and batch records.
Develop and validate analytical methods (e.g., moisture, fat, protein, titratable acidity, pH, solids-not-fat) and coordinate with QC labs to ensure reliable in-process and finished product testing.
Ensure product labeling, ingredient statements and nutritional information comply with applicable regulations (local food law, Codex, FSMA, EU regulations, FSSAI as applicable) and support regulatory submissions where required.
Manage raw material evaluation and supplier qualification for dairy-specific ingredients (cultures, rennet, stabilizers, milk powder, emulsifiers), performing technical audits and coordinating specification agreements with procurement.
Drive product cost optimization initiatives — evaluate ingredient substitution, process efficiencies and yield improvements while performing ingredient and process risk assessments to maintain product integrity.
Collaborate with packaging engineers and suppliers to select packaging solutions that protect dairy product quality and shelf life (barrier requirements, oxygen/moisture transmission, aseptic packaging) and conduct packaging compatibility testing.
Provide technical support for scale-up of new product launches, coordinating pilot runs, scale-up validations, plant trials and operator training to ensure successful commercialization on schedule.
Lead continuous improvement projects using Lean and Six Sigma tools to reduce variability, increase throughput, reduce downtime and improve hygienic design; quantify improvements and communicate ROI to stakeholders.
Prepare and present technical reports, project updates and product dossiers for internal stakeholders, customers and external auditors; summarize lab results, trial outcomes and recommendations in clear, actionable formats.
Train production, QC and QA teams on product-specific processing parameters, critical control points, sanitation practices, sampling plans and handling of starter cultures and sensitive ingredients.
Support cross-functional commercialization activities including sales training, technical support for customer trials, troubleshooting customer complaints and providing technical justifications for product claims.
Maintain up-to-date knowledge of dairy science, emerging processing technologies (membrane filtration, spray drying, UHT, high-pressure processing), regulatory changes and market trends to inform product innovation roadmaps and technical strategies.
Conduct risk assessments for allergen control, cross-contact prevention and recall readiness; develop and maintain recall procedures and support mock recall exercises and traceability testing.

Secondary Functions

Support product cost modelling and BOM (bill of materials) creation for new SKUs, assisting procurement with specification negotiation and supply chain risk mitigation.
Maintain and calibrate laboratory and pilot-plant equipment; schedule preventative maintenance and ensure equipment qualification records are current.
Participate in internal and external food safety audits (customer audits, third-party audit schemes) and support corrective actions and audit responses.
Contribute to sustainability initiatives within the R&D group such as reformulation for reduced environmental footprint, simpler ingredient lists and recyclable packaging options.
Archive and manage R&D records, stability data and technical files to meet internal retention policies and regulatory requirements.
Assist marketing with technical claims, white papers and product factsheets, ensuring scientific accuracy and substantiation of nutritional or functional statements.
