  • Conduct rheology studies and material characterisation to fine-tune formulations for specific applications.
  • Identify and integrate novel raw materials to enhance performance and sustainability.
  • Work on material compatibility studies, ensuring formulations meet required industrial and regulatory standards.
  • Develop prototype samples and conduct performance testing under real-world conditions.
• Analytical Chemistry & Material Characterisation
  • Develop and validate analytical test methods to ensure consistency and reproducibility in formulation performance.
  • Assess film-forming properties, barrier properties, and mechanical performance of coatings and substrates.
  • Interpret data and provide insights to refine formulations based on performance outcomes.
• Scale-Up & Trials
  • Work closely with the process engineer to transition lab-scale formulations into pilot-scale and commercial-scale production.
  • Participate in pilot trials and factory production runs, ensuring formulations perform as expected in real-world conditions.
  • Troubleshoot formulation issues that arise during scale-up, working collaboratively with cross-functional teams.
  • Document all scale-up findings, optimising processes for efficiency and reproducibility.
• Project Management
  • Drive formulation work streams from concept to execution, ensuring key milestones are met on time.
  • Develop and maintain project timelines, coordinating with internal teams and external partners to ensure smooth execution.
  • Communicate project progress effectively with internal stakeholders, providing clear updates and risk assessments.
• Cross-Functional Collaboration
  • Work closely with the entire technical team, ensuring formulation strategies align with process capabilities.
  • Translate complex scientific findings into clear, actionable insights for non-technical stakeholders.
• Quality Assurance & Documentation
  • Ensure formulations meet regulatory and industrial standards, documenting all formulation parameters and testing results.
  • Maintain detailed formulation records, creating Standard Operating Procedures (SOPs) to ensure reproducibility.
  • Work with quality teams to implement quality control measures in formulation testing and production.
• External Partnership Building
  • Identify and engage with external partners, such as material suppliers, labs, specialised contract manufacturers, and technology consultants, to fast-track scale-up activities.
  • Coordinate and oversee development activities with partners to ensure project alignment and adherence to company standards.

• Qualifications & Experience
  • Bachelor’s, Master’s, or PhD in Polymer Science, Materials Science, Engineering, or a related discipline.
  • 5+ years of industry experience in coatings, paper-based materials, or polymer formulation.
  • Strong background in analytical chemistry and material characterization techniques.
• Technical Skills
  • Expertise in natural polymer coatings, surface treatments, and film-forming properties.
  • Hands-on experience with natural polymer formulations (e.g., starches, proteins, cellulose, alginates).
  • Knowledge of barrier coatings, adhesion technologies, and functional additives.
  • Deep knowledge in coating processes and paper production.
• Partnership & Communication Skills
  • Ability to identify, establish, and manage external partnerships to accelerate scale-up activities and overcome resource constraints.
  • Strong communication skills, both written and verbal, with the ability to collaborate effectively across internal teams and external stakeholders.
  • Demonstrated capacity to represent the company in technical discussions with partners and stakeholders.
