PTC Therapeutics is seeking an innovative and motivated scientist to join our Multiomics team in Mountain View, CA. The successful candidate will develop and apply chemoproteomic methods to advance drug discovery programs and translational biomarker strategies. We are looking for someone to join our group who is: organized, methodical, team-oriented, and not afraid to tackle challenging problems. The ideal candidate will be a technical expert in proteomics and have broad knowledge of biological processes associated with either neurodegenerative/neuromuscular disorders, inflammation, immunology, or ferroptosis.

The Scientist I is responsible for the detailed planning and execution of scientific experiments under the guidance of the Executive Director of Multiomics. The incumbent works in matrixed teams and serves as a subject matter expert for programs advancing PTC’s research and drug discovery activities. The Scientist I supports adherence to relevant regulatory requirements and internal Standard Operating Procedures (SOPs) as appropriate.

• Sample processing and enrichment of multiple sample types (e.g. plasma, CSF, tissues, and cells) for downstream proteomics analysis using a variety of techniques including, but not limited to: ultracentrifugation, SP3, SAX, RP/C18, IMAC/MOAC, SEC, FASP, IP, co-IP, etc.
• Daily operation of nano-LC (i.e. Evosep and nano-Elute) instruments as well as ion-mobility and high-resolution mass spectrometers (i.e. Bruker tims-ToF and Thermo Orbitrap).
• Use of label-free chemoproteomic techniques like LiP and TPP as well as directed proteomic analyses such as ABPP or PAL.
• Execution of quantitative proteomic workflows using TMT, SILAC, spiked-in isotopically labeled standards, or PRM analysis.
• Analysis of proteomic datasets using Spectronaut, MS Fragger, DIA-NN, Skyline, etc.
• Integrates multiomic datasets and uses pathway analyses to correlate observed changes with disease phenotype, treatment effect, or translational biomarker identification.
• Communicates effectively and cooperates with cross-functional teams to plan and execute strategies to achieve program and corporate goals.
