Clinical Research and Development
Responsibilities:
- Physicochemical characterization of pharmaceutical materials (API, intermediates, peptides, novel excipients, drug-product intermediates, drug products).
- Use expertise in physical organic chemistry/materials science on crystallization, polymorph/salt selection, drug-excipient compatibility, characterization of amorphous solid dispersions, and physical stability.
- Collaborate with cross-functional teams and build internal/external scientific networks (academic and regulatory).
Education Requirements:
- Bachelor’s or Master’s in Materials Science/Engineering, Chemistry, Chemical Engineering, Pharmaceutical Sciences (or related) + minimum 8 years relevant non-academic industrial experience.
- OR PhD in the same fields + 4 years relevant non-academic industrial experience.
Required:
- Expertise in materials science/physical chemistry and materials characterization (XRD, thermal analysis, electron microscopy, vibrational spectroscopy, particle size analysis, powder property characterization).
- Strong academic record (peer-reviewed publications; presentations).
- Self-motivated, creative, energetic; ability to solve complex problems.
- Strong written and verbal communications.
Preferred:
- API polymorph screening/crystallization; amorphous solid dispersion characterization.
- Modified release dosage forms; automation and data science.
- Late-stage development and regulatory documentation/filing.
Skills (required):
- Analytical Chemistry/Method Development, assay development, chromatographic techniques, crystallizations.
- HRMS, LC-MS/mass spectrometry analysis, PAT, protein analysis.
