Job description

We’re hiring: Scientist – Surface Chemistry & Biosensing

Bioherent | Málaga, Spain

We’re looking for a hands‑on scientist with a background in materials science or chemistry and practical biosensor experience to help develop optical biosensing technologies for in vitro diagnostics.

What you’ll do:

• Develop functional materials, surface coatings, and nanostructures for biosensing.
• Optimize surface functionalization and biomolecule immobilization, particularly on silicon substrates.
• Characterize materials and surfaces and investigate their effects on sensor sensitivity, background, stability, and reproducibility.
• Improve consistency between functionalization batches and support the transfer of laboratory methods into scalable processes.
• Work closely with chemists, immunoassay scientists, and engineers, documenting methods and findings clearly.

What we’re looking for:

• BSc, MSc, or PhD in Materials Science, Chemistry, Nanotechnology, Chemical Engineering, Applied Physics, or a related field.
• 3+ years of relevant experience in research, R&D, or applied materials development.
• Strong experimental design, data analysis, and troubleshooting skills.

Experience with silicon-based biosensors or optical and photonic platforms would be particularly valuable. Other relevant expertise includes silanization, bioconjugation, antifouling coatings, nanoparticles, and surface characterization techniques such as XPS, AFM, contact-angle measurements, or electron microscopy.

We welcome materials scientists and chemists with biosensor experience who enjoy connecting material design and surface chemistry with practical diagnostic performance.
