Protein (Sr.) Scientist


We are seeking a motivated scientist in the area of Protein Science and Biostructure, including biochemical and biophysical methods. A successful candidate should play key roles in target validation and protein design and production, hit identification, hit validation by biophysical method. She or he responsibilities also will include X-ray Crystallography.


  • Design, express/purify, and characterize proteins of therapeutic interest.
  • Perform SPR and biophysical assay to characterize protein-ligand, protein-protein, interactions
  • Perform protein crystallization and X-ray, collect diffraction data.
  • Preliminary structural analysis.
  • For senior scientist, Associate Director
    • Excellent presentation, writing and coaching skills.
    • Experience preferred in program leadership: high level skills leading a drug discovery program to success, leveraging know-how & accountability from areas outside your own area of expertise and function.
    • Experience working in new directions, building new platforms or bringing in new methods/technologies in protein science


  • MS or PhD (or relevant experience) in protein chemistry, biochemistry, enzymology or biophysics with 3-5 years of drug discovery experience. Experience in pharmaceutical or biotech company is preferred.
  • Excellent publication and established track record.
  • Solid knowledge and experience in expression vector construction, multiple protein expression systems and various purification techniques.
  • Expertise in biophysical techniques including SEC-MALS, SPR, ITC and TSA, etc.
