Senior Research Scientist, Chemical Biology & Proteomics

We are seeking a highly motivated and talented scientist to join our Chemical Biology & Proteomics (CBP) team at AstraZeneca in Waltham, MA. As a Senior Research Scientist, you will be an integral member of a team generating pre-clinical pharmacology data to understand efficacy and selectivity of therapeutic agents. You will have the opportunity to work with a team of cross-functional scientists and support the development of new and successful therapies for patients. If you’re inspired by the possibilities of science to make a difference and ready to discover what you can do – join us. 

Key Responsibilities 

• Develop and employ chemical tools and proteomics technologies to provide impactful mechanistic insights for drug discovery projects across therapeutic areas 

• Develop mass spectrometry-based methods to conduct covalent screens  

• Design and execute experimental plans to understand target engagement and selectivity profiles of therapeutic agents, understand drug-induced proteome dynamics and investigate post-translational modifications (PTM) 

• Represent CBP team, and communicate with project discipline leads, and contribute to generation of mechanistic hypothesis through interpretation of sophisticated proteomics data 

• Maintain and troubleshoot LC-MS system 

Essential Requirements 

• PhD with 2+ years of post-doctoral/industrial experience 

• Knowledge and hands-on experience with sample preparation and method development on quantitative mass spectrometry (relative and/or absolute protein quantification) 

• Experience with mass spectrometry-based covalent screening, and proven expertise with IP-MS or chemical probe-based enrichment MS workflows, and experience developing automated processes to analyze large number of samples for MS analysis 

• Skilled in investigating compound effects under biochemical and cellular settings with quantitative mass spectrometry, e.g. PTMs, protein complexes perturbations, etc 

• Experience in determining protein abundance and turnover by using quantitative proteomics technologies, such as TMT, SILAC, and/or label-free approaches and data independent acquisition (DIA) 

• Expertise in data analysis and an ability to communicate data interpretation clearly 

• Significant external reputation gained through professional recognition, external presentations and publications in high-impact journals 

• Ability to contribute with a positive, result oriented and problem-solving attitude 

Desirable Requirements 

• Experience in pre-clinical drug discovery 

• Experience using Thermo Q-Exactive, Orbitrap Exploris, Eclipse, Astral Zoom or TimsTOF 

• Experience with Xcalibur, Proteome Discoverer, MaxQuant, Skyline, Spectronaut and DB search engine tools 

• Experience with liquid handling systems and robotic automation 

• Familiarity with targeted proteomics is a plus
