Company Description
MarinaTex is an advanced biomaterials company developing and supplying high-performance biomaterials and coatings as commercially scalable replacements for plastic.
Our platform technology spans a broad range of natural, renewable biopolymers. We supply biomaterials as a product line in their own right, and convert them into functional coatings and materials that integrate into existing manufacturing and conversion infrastructure. We work across packaging, paper and board, agriculture, and other high-volume sectors, engineering plastic-free solutions that meet real performance and commercial requirements at industrial scale.
Backed by strategic investors, we operate at the intersection of materials science, industrial formulation, and commercial deployment, partnering with global brands, manufacturers, and converters to bring natural materials into everyday products.
Role Description
MarinaTex develops high-performance natural polymer materials as commercially scalable replacements for plastic. We are hiring a Coatings & Product Development Scientist to establish and lead a new capability for MarinaTex: formulating and applying functional and barrier coatings onto paper, paperboard, film, and other substrates. You will lead coatings work, drive products from lab to pilot to commercial support, and contribute to biomaterials production, working closely with the Head of NPD, the wider team, and the CEO. Based at BioCity Scotland, accessible from both Glasgow and Edinburgh.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You Will Do
- Formulate and optimise natural polymer coatings for paper, paperboard, film, and other substrates.
- Run coating trials and dial in method, coat weight, and drying; solve real formulation and process problems.
- Build barrier performance: grease and oil, moisture and water resistance, adhesion, film integrity.
- Test and benchmark coated substrates against plastic-based coatings (Cobb, KIT, WVTR, and more) to TAPPI, ASTM, and ISO.
- Support biomaterials production and technology transfer from lab to pilot and manufacturing, including converter and customer trials.
What We Need
- Hands-on experience formulating or applying coatings to paper, board, or other substrates, in industry or applied R&D.
- A degree in Chemistry, Materials Science, Polymer Science, Coatings Technology, Paper Science, or a related field, or equivalent industrial experience. An MSc is desirable, not essential.
- A working grasp of coating principles: rheology, dispersion, wetting, adhesion, coat weight, and drying.
- Experience with one or more coating processes (rod, blade, roll, spray, gravure, slot-die, or curtain).
- Comfort across development and routine production in a fast-moving environment, with autonomy and ownership.
- Genuine motivation for the mission: replacing conventional plastics with high-performance natural alternatives.
- Comfortable using AI tools for reporting, documentation, and everyday technical work.
