Our focus is on accelerating drug development and transforming personalized medicine for our pharma and biotech clients. We are an agile, highly collaborative team of passionate scientists, committed to making innovations with scientific rigor, and executing in a timely manner in accordance with key regulatory standards. Combining state-of-the-art mass spectrometry technology with advanced biocomputational services and multifaceted human health data, we enable biomarker discovery at unprecedented speed and scale to provide a deeper understanding of human biology and effectively align biological targets, patients, and drug therapies in support of our clients. About the Role We are in search of a Research Scientist II|/Senior Research Scientist with expertise primarily in proteomics workflows for complex matrices (e.g., biosamples) to join our interdisciplinary bioanalytical team here at Sapient. As an RSIII/SRS, you will be responsible for performing laboratory experiments such as the preparation of clinical and biological samples for global/targeted proteomics analyses using medium to high throughput liquid chromatography mass spectrometry instrumentation. What we’re looking for For RSIII/SRS: Experience with size exclusion chromatography, nanoparticle and other proteomics enrichment preparations, BCA and SPE techniques. Familiarity with mass spectrometry techniques (preferably untargeted LC–MS, however targeted LC–MS is also favorable) and working in a BSL2/BSL2+ environment. Experience with custom data workflows and data analysis required (i.e., Skyline, Spectronaut, mzmine) Bachelor's degree in biology, Biochemistry, Chemistry, or a related Life Science field and 3+ years of related work experience or a master’s degree with 1 year of related work experience. Responsibilities/Skills Technical Duties Prepares samples using techniques such as size exclusion chromatography, nanoparticle enrichment and solid phase extraction. Prepares protein samples from a wide range of specimens (e.g., cells, tissue, biofluids, recombinant proteins) for discovery and targeted proteomics analysis. Conducts global proteome profiling by data-dependent (DDA) and data-independent (DIA) acquisition mass spectrometry, as well as experiments for post-translational modifications (e.g., phosphorylation, acetylation). Conducts relative and absolute quantitative analysis using Parallel Reaction Monitoring (PRM) mass spectrometry. Uses key software tools for proteomics data analysis (e.g., Spectronaut, Skyline, MSFragger). Independently operates laboratory equipment and performs basic troubleshooting and routine maintenance on instruments (e.g., timsTOF Pro2, ThermoStellar). Assists with developing new methods for testing in the laboratory and maintains detailed records of development, interpretation and results. Maintains clear and organized electronic laboratory notebook (ELN), documenting protocols, reagent preparation, and results of all experiments performed in real time. Reviews and QC’s analytical data using manual and automated pipelines and uses analytical abilities to make decisions regarding the accuracy of results. Performs all responsibilities in adherence with regulatory principles and best laboratory practices such as GLP/GCP. General Duties Performs all responsibilities in adherence with regulatory principles and best laboratory practices such as GLP/GCP.
