Our award-winning culture is collaborative, innovative, and science based. If you have a passion for challenges and the opportunities that lay within them, you’ll thrive as part of the Amgen team. Join us and transform the lives of patients while transforming your career. Senior Scientist – Protein Biochemist What you will do Let’s do this. Let’s change the world. In this vital role you will be responsible for designing, planning, and executing the generation of key enabling reagents that support the structure determination of target molecules via X-ray crystallography and/or cryo-electron microscopy (cryo-EM). You will collaborate closely with structural biologists within the group and contribute to advancing our drug discovery efforts. The ideal candidate must possess flexibility in applying their knowledge to new areas of study and have strong interpersonal and communication skills to thrive in a collaborative environment. Key responsibilities: Protein Biochemistry: Be actively involved in the design and execution of construct design, molecular cloning and protein expression strategies with the Amgen Discovery Protein Sciences team and/or CROs; design and execute purification strategies to support the structure determination of drug targets in complex with therapeutic molecules. Collaborative Support: Work closely with structural biologists to generate high-quality protein samples for structural biology techniques, particularly X-ray crystallography and cryo-EM. Method Development: Develop and optimize purification protocols and reagents, ensuring high protein purity, homogeneity, and stability for structural studies. Characterization and Quality Control: Use biochemical and biophysical techniques (e.g., SDS-PAGE, Western blot, spectrophotometry, SEC-MALS, SPR, mass spectrometry) to assess protein quality and stability. Collaborate with team members to provide structural biology insights into the mechanism of action (MOA) of target proteins. Project Management: Manage multiple projects simultaneously, ensuring they are completed within timelines while meeting high-quality standards. Team Communication: Present research finds effectively in both written and oral formats for internal teams and external collaborators in a timely and transparent manner. Innovative Thinking: Continuously troubleshoot and optimize experimental workflows, applying creative solutions to overcome challenges in protein production and purification. What we expect of you We are all different, yet we all use our unique contributions to serve patients. The Senior Scientist we seek is a professional researcher with these qualifications. Basic Qualifications: Doctorate degree PhD OR PharmD OR MD [and relevant post-doc where applicable] OR Master’s degree and 3 years of Molecular, Structural Biology experience. OR Bachelor’s degree and 5 years of Molecular, Structural Biology experience. Preferred Qualifications Demonstrated expertise in expression, purification, and quality assessment of challenging recombinant proteins, with a track record of producing material suitable for cryo-EM, X-ray crystallography, or other structural biology applications. Strong hands-on experience with membrane proteins , including GPCRs; experience with other challenging protein classes is also highly valued. Deep understanding of protein stability, folding, homogeneity, and aggregation , with a hypothesis-driven approach to troubleshooting low expression, instability, heterogeneity, aggregation, or poor complex formation. Experience with mammalian, insect, and/or microbial expression systems . Expertise in chromatography-based purification , including affinity, ion exchange, hydrophobic interaction, and size-exclusion chromatography, using systems such as Cytiva ÄKTA or Agilent HPLC. Proficiency with biochemical and biophysical methods relevant to protein quality and complex formation, such as SDS-PAGE, immunoblotting, analytical SEC, SEC-MALS, DLS, SPR, and mass spectrometry. Excellent communication, prioritization, and collaboration skills , with the ability to independently manage multiple deliverables in a fast-paced research environment. Strong dedication and commitment to protein purification in support of structural biology projects.
