Role Description
We are looking for a dynamic individual to join our Chemical Biology team in Pfizer's Oncology Research and Development organization. The candidate will join a multi-disciplinary team responsible for enabling studies on target biology and compound mechanism of action through the application of cutting-edge chemical biology approaches. The individual should be a highly skilled laboratory experimentalist with experience working with biological systems and applying quantitative mass spectrometry technologies to deliver biological insights through chemical biology experimentation. The successful candidate will be effective building strong relationships cross functionally and working in a highly collaborative environment to advance the oncology portfolio.
Work collaboratively with Oncology drug discovery and target identification teams to apply chemical biology approaches that enhance the Oncology portfolio

Use chemical proteomics to elucidate biological targets of active molecules emerging from phenotypic screens to expedite drug discovery efforts.

Design and implement novel chemical biology applications to enable target engagement, identification, and localization

Apply quantitative MS technologies and associated proteomic platforms (Proteome Discover, IP2).

Apply affinity/activity-based proteomic probes to profile the functional state of enzyme targets in native biological systems to assess the potency, selectivity and safety of small molecule inhibitors.

Work in collaboration with Medicinal Chemistry to conceive, prepare and validate chemical probes.

Maintain a high level of productivity in the laboratory setting
Education and Training

Doctoral level degree in biological or chemical sciences

Post-doctoral training in chemical biology or related area (minimum 1 year) preferred

Highly skilled laboratory experimentalist with experience of working on biological systems (cells/cell lysates/ex vivo tissues etc).

Strong track record of delivering biological insights through chemical biology experimentation

Experience using mass-spectrometry and chemical biology strategies for small molecule target deconvolution and mechanism of action studies

Experience working in the following areas would be desirable: mammalian tissue culture, Click chemistry; photoaffinity cross-linking; in-gel fluorescence; chemical modification of proteins; protein engineering; SILAC methodology; siRNA for target validation

Comprehensive knowledge of applying chemical biology probes

Quantitative analytical skills

Proven effective written and verbal communication skills

Don't Be Fooled

The fraudster will send a check to the victim who has accepted a job. The check can be for multiple reasons such as signing bonus, supplies, etc. The victim will be instructed to deposit the check and use the money for any of these reasons and then instructed to send the remaining funds to the fraudster. The check will bounce and the victim is left responsible.
