What is a scientist toxicology?

A Scientist in Toxicology studies the effects of chemicals, drugs, and other substances on living organisms to assess their safety and potential risks. They conduct laboratory experiments, analyze biological data, and help develop regulations to protect human health and the environment. Toxicologists work in various industries, including pharmaceuticals, environmental science, and regulatory agencies. Their research helps determine safe exposure levels and guides risk assessments for public health and product safety.

What are the typical daily responsibilities of a scientist toxicology?

A Scientist Toxicology typically spends their day designing and conducting experiments to assess the safety and effects of chemicals or pharmaceuticals, analyzing biological samples, and interpreting data to identify potential hazards. You may also be responsible for preparing detailed reports, ensuring compliance with regulatory standards, and presenting findings to stakeholders or regulatory agencies. Collaboration with other scientists, lab technicians, and regulatory specialists is common, requiring effective teamwork and communication skills. This engaging role often balances hands-on laboratory work with data analysis and scientific documentation.

What are the key skills and qualifications needed to thrive in the scientist toxicology position, and why are they important?

To thrive as a Scientist Toxicology, you need a strong background in biology or chemistry, laboratory research experience, and typically an advanced degree in toxicology or a related field. Familiarity with analytical instruments like mass spectrometers, data analysis software, and regulatory guidelines (such as GLP or OECD) is essential. Exceptional analytical thinking, attention to detail, and effective written and verbal communication help you excel in this role. These skills ensure accurate hazard assessments, clear reporting, and impactful collaboration with cross-functional teams in a highly regulated environment.

Job description

Legend Biotech is seeking a Sr. Scientist, Toxicology as part of the Early Drug Development team based in Somerset, NJ or Philadelphia, PA.

Role Overview

Legend Biotech is seeking a Sr. Scientist, Toxicology to support nonclinical development and safety assessment across cell and gene therapy programs. This individual will contribute to nonclinical strategy from discovery through IND-enabling development and support regulatory submissions for innovative advanced therapies. The role requires scientific expertise in toxicology, a foundation in pharmacology, understanding of regulatory expectations, and the ability to work effectively across cross-functional teams in a fast-paced biotech environment.

Key Responsibilities

  • Support toxicology activities for discovery and development-stage cell and gene therapy programs.
  • Design, monitor, interpret, and report nonclinical safety, pharmacology, biodistribution, and pharmacokinetic studies.
  • Support integrated interpretation of toxicology and pharmacology data to enable candidate selection, risk assessment, and program progression.
  • Contribute to study strategy and execution at CROs, including protocol review, study monitoring, data interpretation, and final report review.
  • Partner closely with Pharmacology, CMC, Clinical, Regulatory Affairs, and Program Management teams to advance development programs.
  • Support preparation of regulatory documents, including briefing packages, pre-IND/IND submissions, investigator brochures, and responses to health authority questions.
  • Contribute to safety risk assessments related to target biology, exaggerated pharmacology, off-target effects, immunogenicity, genome-related risks, and long-term safety.
  • Interpret complex nonclinical datasets and communicate key findings and recommendations clearly to internal stakeholders.
  • Stay current with scientific and regulatory advances relevant to toxicology, pharmacology, and cell and gene therapy development.
  • Support in vivo pharmacology activities, when needed, through integrated assessment of efficacy, disposition, and safety findings.

Requirements

  • Ph.D., DVM, PharmD, or equivalent degree in Toxicology, Pharmacology, Immunology, or a related discipline.
  • Minimum of 5 years of experience in nonclinical toxicology or a related field within biotechnology or pharmaceutical R&D, with working knowledge of pharmacology principles.
  • Experience supporting cell therapy, gene therapy, biologics, or other advanced therapeutic platforms preferred.
  • Working knowledge of GLP toxicology studies, nonclinical pharmacology studies, CRO management, and regulatory expectations for nonclinical development.
  • Experience contributing to IND/CTA-enabling packages and global regulatory submissions is highly desirable.
  • Understanding of FDA, EMA, and ICH regulations pertaining to toxicology and cell and gene therapy development.
  • Scientific writing, communication, and presentation skills.
  • Ability to work independently while thriving in a collaborative, matrixed team environment.
