Job Description

Umbra Therapeutics is mapping the tyrosine and lysine proteome to develop impactful therapeutics against diverse target classes.  We are integrating advanced chemoproteomics technologies & bioinformatics with computational chemistry, structural biology and medicinal chemistry capabilities to develop novel, selective therapies in oncology.  Our capabilities empower the discovery of novel druggable sites within proteins including those that have been previously regarded as undruggable and inform rational drug design. Our vision is to be the premier company building a pipeline of next-generation small molecule therapeutics for high-value protein targets.  
About the Role:

Umbra is seeking an experienced and passionate Director of In Vitro Pharmacology and Screening to leverage the latest advances in drug discovery, medicinal chemistry, and computational biology to discover novel, promising new anti-cancer drugs.  The Role will be integrated to work alongside other functional capabilities of the company including chemoproteomics, medicinal chemistry, computational chemistry and disease area biology.
We are seeking a candidate with the following qualities/qualifications.

  • Ph.D. and post-doctoral work in a Cell Biology, Pharmacology or related field and 10+ years of relevant industry experience including advancing small molecule programs from discovery through IND-enabling studies.
  • Strong background in biochemistry, cellular biology and pharmacology, with a thorough understanding of molecular pathways important in cancer biology, mechanistic pharmacology of diverse, targeted cancer therapeutics, with a broad experience of various targets and mechanism of actions.
  • A very high level of motivation and a proven track record of accomplishments (e.g., a strong publication record in top-tier journals, biology project leader, development candidate nominations)
  • An individual who enjoys working in close collaboration with colleagues in the research, development, business development, finance, and administrative areas of the company, as well as Umbra’s external partners, vendors, and consultants.

  • Excellent interpersonal skills, leadership abilities, and oral and written communication skills

  • The successful candidate will have primary oversight over screening, confirmation, mechanistic studies, covering biochemical and cellular assays for pipeline building activities – from target selection through establishment and validation of all assays required for hit identification and lead optimization.
  • Be a critical member of the Discovery Leadership Team, creating and executing research strategies for multiple discovery programs with clear go-no/go decisions, helping assess and develop Target Product Profiles for programs under consideration.
  • Direct, manage, develop, and empower a team of internal and external scientists in in vitro screening and pharmacology; outline and communicate research goals, design key studies, and analyze data.
  • Together with the broader multi-disciplinary Umbra team, manage and interact directly with external CROs focusing on preclinical mechanism of action studies, compound screening, functional cell biology and in vivo efficacy experiments, reagent generation, assay development / validation and computational biology activities.
  • Leverage a network of external scientific advisors, academic collaborators, and consultants to develop and execute research activities.
  • Overall, have a very hands-on role with respect to your direct contributions to our Discovery efforts, while being an outstanding leader and collaborator, a creative problem-solver, and a role model for your reports and across the organization.
