We are seeking a highly skilled and proactive Paper & Coating Engineer with industry experience in paper and coatings to join our growing R&D team. This role is critical in developing and optimising seaweed-based formulations, ensuring they meet performance requirements and can be successfully scaled up for commercial use. The Paper & Coating Engineer will work closely with a formulation scientist and a process engineer, collaborating on research, formulation, and process improvements. This is an exciting opportunity to drive impactful R&D work for commercial projects.

Key Responsibilities

Design and optimise seaweed-based coatings and paper formulations, balancing key properties such as adhesion, flexibility, barrier performance, and biodegradability.
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

Education & Industry Background

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.
