Job Description — Senior R&D Scientist (Bio-based Adhesives)
Location: Braga, Portugal | Full-time | On-site
Deadline: 15th December, 2025
About BestHealth4U
At BestHealth4U, we're shaping the future of medical solutions through innovation, sustainability, and patient-centred design. Our latest innovation, Bio2Skin, is a pioneering bio-based adhesive platform that redefines how medical devices interact with the skin — ensuring strong yet gentle adhesion while protecting skin integrity and promoting long-term health.
About the Role
We are seeking a Senior R&D Scientist to lead the development and optimization of bio-based, biocompatible adhesive materials for medical applications. This role will focus on advancing the Bio2Skin platform and translating scientific insights into scalable, high-performance formulations.
What You'll Do
* Design, synthesize, and characterize bio-based polymeric adhesives for skin-contact medical devices
* Develop and optimize polyester-based formulations, ensuring controlled adhesion and biocompatibility
* Perform chemical, physical and mechanical testing to evaluate performance under various conditions
* Collaborate closely with multidisciplinary teams (chemists, biomedical engineers, clinicians) to bridge lab-scale innovation with product development
* Contribute to scientific publications, patents, and regulatory documentation supporting product validation and certification.
What We're Looking For
* PhD in Chemistry, Polymer Science, Materials Science, Chemical Engineering, or related fields
* 3+ years of industrial R&D experience, preferably in adhesive systems or polymeric materials
* Proven experience with adhesive formulation, polymer synthesis, and characterization techniques (FTIR, DSC, TGA, rheometry, SEM, adhesion, etc.)
* Strong understanding of bio-based polymers, skin-bonding systems, and structure–property relationships in polymer networks
* Knowledge of medical device standards and biocompatibility requirements (ISO 10993, MDR) is an asset
* Creative thinker with a problem-solving mindset, capable of working independently and collaboratively in a startup environment.
Why Join Us
* Be part of a pioneering project redefining the medical adhesive landscape
* Contribute directly to a sustainable, clinically relevant innovation addressing a major unmet need (MARSI prevention)
* Collaborate with a passionate, multidisciplinary team at the intersection of materials science, MedTech, and green innovation
* Competitive salary and an inspiring, flexible work environment.
