Job Description:

Unique opportunity to contribute to both science and culture of Kymera Therapeutics, a biotechnology company pioneering a transformative new approach to treating previously untreatable diseases. The company is advancing the field of targeted protein degradation, accessing the body’s innate protein recycling machinery to degrade rather than inhibit dysregulated, disease-causing proteins.

The Head of Toxicology will be part of the Preclinical Development group supporting small molecule drug development at Kymera and will provide scientific expertise and leadership to the safety assessment of all Kymera programs – from lead identification through to clinical development. The candidate is expected to work in a highly collaborative team environment, playing a pivotal role at each stage of preclinical and early clinical development.


  • Provide expert support, guidance and strategy on project safety assessments, with a specific focus on discovery & IND-stage small molecule projects.
    • Serve as the key resource for toxicology, providing scientific knowledge and expertise to cross-functional project teams.
    • Develop overall toxicology strategy and plans for lead candidates based on clinical development plan.
  • Oversee preclinical toxicology studies at multiple external Contract Research Organizations (CRO).
    • Design & execute investigative toxicology studies, based upon off & on-target safety profiles of the candidate drugs.
    • Initiate appropriate processes for contract implementation, protocol development, and timeline optimization for toxicology studies.
    • Monitor toxicology studies for appropriate conduct, accuracy and timely execution; audit raw data for accuracy, review draft reports and finalize them as submission-ready documents for regulatory authorities.
    • Proactively respond to study issues and resolve problems with study director.
  • Internal and external communication
    • Prepare verbal and written summaries for internal discussions. Work with the Preclinical Development team to develop optimal strategies to address specific safety issues and partner with project teams.
