About Us:
Demeter Bio is a frontier materials company advancing the next generation of PFAS-free materials. We combine polymer systems, biomimicry, materials engineering, and sustainable chemistry to address urgent performance and environmental challenges facing modern industries.
Role Overview
We are seeking a Coating Scientist with strong industrial formulation experience to support the development of PFAS-free durable water and oil repellent (DWOR) technologies across a range of substrates and industrial applications.
You will drive coating formulation and surface engineering from lab scale through pilot validation, working at the intersection of polymer science, surface chemistry, and coating application processes and other industrial application methods.
This role is ideal for someone who wants to create category-defining sustainable coating materials with real-world industrial impact.
Formulation & Development
- Design and optimize coating formulations to meet target performance specifications
- Develop polymer systems for durable, high-performance coatings
- Engineer coatings for durability, breathability, and substrate feel/finish
- Optimize formulations for manufacturability, cost, and processing robustness
- Assess formulation stability, rheological behaviour, and relevant physicochemical properties
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.
Application & Testing
- Apply and modify coatings for specific application methods (kiss roll, foulard/pad, spray, and other industrial techniques), adjusting rheology, viscosity, and wet pick-up as needed
- Evaluate coating performance using standardised tests
- Improve adhesion to target substrates
- Interpret performance results in the context of industrial processing conditions
- Support translation of laboratory formulations into pilot-scale coating trials
Surface & Materials Characterization
- Analyze surface properties, energies and coating morphology
- Optimize coating-substrate interactions and durability mechanisms
- Collaborate on analytical testing
Education
- PhD or MSc in one of the following:
- Chemistry / Chemical Engineering
- Polymer Chemistry / Polymer Science
- Materials Science
- Physical Chemistry (Surface & Interface focus)
- Coatings Science

Your very own career expert that helps elevate your application to the next level.
Experience
- Proven experience developing coating finishes
- Preferred experience with coating application methods (kiss roll, foulard/pad, spray, or similar) and modifying formulations to suit them
- Hands-on coating formulation experience
- Experience designing experiments, analysing formulation data, and establishing structure-property relationships
- Experience with rheology, surface characterisation and polymer systems would be highly desirable
- Ability to troubleshoot formulation and coating-performance challenges through a hypothesis-driven scientific approach
Who You Are
- Lab-Savvy: You have hands-on lab experience, ideally in a coating development setting.
- Available On-Site: You’re able and excited to work physically in our lab during weekdays in London (core hours).
- Right to Work: You must have the right to work in the UK. Demeter Bio is unable to sponsor work visas at this time.
- Startup-Minded: You’re proactive, driven, resourceful, and thrive in dynamic environments where no two days are the same.
If this is you, fill in the form on the application and we’ll be in touch!
