Job Description Summary

Mirati Therapeutics is seeking a highly motivated and collaborative Scientist to join the Biology group within the Mirati Research department to assist with on-going oncology programs. The successful candidate will support the development of novel small molecule targeted therapies by running weekly assays and performing deeper characterization of lead molecules using a variety of cell-based assays. The candidate will be an integral part of a fast-paced research team and will be expected to efficiently execute experiments that may ultimately guide Go/No-go decisions. The successful candidate will preferably have experience with mammalian cell biology, high-throughput assay development, molecular biology techniques, and in vivo pharmacology. The candidate may also support translational-stage programs, so experience with biomarker identification and execution and evaluation of plate-based combination assays is a plus.

Your Responsibilities

  • Design, execute and interpret experiments to propel drug discovery and lead matter characterization (includes plate-based weekly screening, in vitro compound characterization, in vivo PK/PD and TGI study designs, and ex vivo analysis)
  • Characterize lead matter by performing weekly cell-based assays based on project-specific needs (e.g. Luciferase reporter gene assay, ELISA, western blot, luminescence assays, HTRF), using high-throughput assay formats and automation
  • Use a variety of molecular and cellular approaches to dissect molecular signaling pathways and elucidate gene function and drug action in vitro and in vivo, including combination platforms
  • Generate in vivo pharmacokinetic and pharmacodynamic data in relevant tumor models, contribute to study design and evaluation
  • Effectively communicate experimental plans, execute experiments, analyze results, and present data at team meetings
  • Upload primary data into the database and maintain an up-to-date electronic notebook.
  • Work collaboratively across multiple project teams
  • Opportunities for management responsibilities, including but not limited to managing students and/or summer interns

What is Required

  • BS/MS or equivalent with 3+ years lab research experience in biology or related field.
  • Excellent written and verbal communication skills
  • At least 2 years of cell biology experience preferred
  • Mammalian cell culture (primary and immortalized) experience required
  • Experience with a broad range of molecular biology techniques (e.g. qRT-PCR, western blotting/JES, flow cytometry)
  • Ability to independently execute experiments and perform data analysis
  • Independent and self-driven with good interpersonal skills and strong sense of urgency in applying skills to create new medicines for cancer patients
