Senior Scientist/Principal Scientist, Non-Clinical Development

Mozart Therapeutics is an early-stage biopharmaceutical company located in Seattle, focused on developing novel immune modulators that specifically target a subset of T lymphocytes to delay the onset and ameliorate targeted autoimmune diseases. We are seeking a highly motivated and experienced individual who can work in a dynamic start-up environment to take on a functional area leadership role in Mozart’s Non-Clinical Development group. The successful candidate will be a skilled immunologist/cell biologist with experience that directly contributes to non-clinical pharmacology and IND-enabling studies supporting development of Mozart therapeutic candidates, including managing CROs and oversight of the execution of GLP studies. This position requires broad knowledge and hands-on experience of in vitro and in vivo studies to understand cross-reactivity across toxicology platforms and will support pilot and GLP studies to advance programs towards IND submissions. Strong understanding of T-cell biology and impact of therapeutics on T-cell function in non-clinical and early phase clinical studies and understanding of PK/PD approaches is required. A strong track record of previous scientific contributions resulting in program progression is also required. Previous experience in non-clinical development of candidates for autoimmune diseases is desired.


  • Provide scientific execution for development programs including experiments and strategies to enable the non-clinical path for selected therapeutic candidates.
  • Adhere to the project’s non-clinical timelines to advance projects from Lead Candidate Selection into clinical development.
  • Design and perform critical path pilot (non-GLP) and GLP non-clinical studies to advance novel therapeutic molecules for the treatment of patients with autoimmune diseases. 
  • Develop biomarker strategies for IND-enabling safety studies and early clinical phases of development, including evaluation of cytokines/soluble proteins, immunophenotyping (flow cytometry), and bioanalysis and pharmacokinetics associated with non-clinical studies.
  • Perform laboratory bench work, as needed, to support assay development, evaluate and select techniques, procedures, and criteria as it pertains to early pilot and non-clinical studies of selected therapeutic candidates.
  • Perform data processing and analysis, integrate, interpret, and present data, make conclusions, and propose next steps to advance project. 
  • Contribute to regulatory documents and associated materials, incorporating GxP processes, reports, and guidelines.
  • Collaborate and contribute to multidisciplinary teams in the progression of development candidates. 
  • Represent the company/program teams at scientific conferences and in internal meetings with senior management. 


  • Candidates at the Sr. Scientist level should have a PhD with minimum of 5 years or MS level with minimum of 12 years experience.  Candidates for the Principal Scientist level should have a PhD with a minimum of 8 years or MS with a minimum of 15 years experience.  Experience should be in the therapeutic areas of non-clinical pharmacology, non-clinical safety and/or immunotoxicology to support candidates in autoimmune diseases in a biotechnology setting. Graduate degree in immunology, cell biology, pathology or a related field with relevant preferred previous industry experience is preferred. 
  • Demonstrated track record in advancing a project or program through non-clinical development and supporting IND submissions.
  • A broad understanding of the requirements of drug development and experience in the design of the experimental strategy for non-clinical animal models in the development of immune-modulating therapeutics is required.
  • Understanding and experience with MABEL and NOAEL approaches to inform first in human clinical doses and clinical exposure.
  • Excellent critical thinking and scientific acumen, with a demonstrated ability to analyze, interpret, and clearly communicate (orally and in writing) complex results and their impact to program and regulatory strategy. 
  • Track record of working with CROs for non-clinical studies and support of IND-enabling studies including experience with oversight of assay development, transfer, and validation of methods for the development of immune modulatory biologics. 
  • Prior project/leadership experience is preferred at the Sr. Scientist level and required at the Principal Scientist level
  • Experience working in highly collaborative and dynamic research environment.
  • Expert in use of scientific software and applications (including, for example, FlowJo, GraphPad Prism, JMP, SoftMaxPro) and MS Office programs
