About this opportunity

Job Description

Vertex Pharmaceuticals is seeking a highly motivated and innovative scientist to join our Predictive and Investigative Safety Assessment (Toxicology) group in San Diego as a Research Scientist. This lab-based role offers an exciting opportunity to lead the development of advanced 3D organoid models, organ-on-a-chip technologies, and fit-for-purpose assays to investigate toxicological mechanisms and support our therapeutic discovery and development efforts. The successful candidate will have a proven track record of working with complex in vitro models, including primary cells and immune cells in 3D formats or co-culture systems, and will bring expertise in developing and applying innovative approaches to assess molecular toxicities. The ideal candidate will have a strong background in cellular biology, toxicology, and advanced in vitro model systems, with demonstrated experience in tissue engineering and assay optimization. Experience with immune cell co-culture models, primary cell systems, and high-throughput plate formats is highly desirable.

Key Duties and Responsibilities:

Design and develop fit-for-purpose assays to investigate toxicological mechanisms using advanced 3D organoid models, organ-on-a-chip technologies, and/or co-culture systems.

Lead the development and application of innovative platforms for studying toxicology in multicellular systems, including immune cell interactions and primary cell-based models.

Develop and optimize assays to evaluate toxicological mechanisms, with a focus on precision, reproducibility, and scalability.

Collaborate with cross-functional teams to integrate advanced  in vitro  models into drug discovery workflows, supporting safety assessment and therapeutic development.

Apply cutting-edge technologies, including automation and high-throughput plate formats, to enhance assay performance and throughput.

Partner with Systems Toxicology to generate and analyze complex biological datasets from  in vitro  models, enabling the identification of toxicological mechanisms and establishing  in vitro-in vivo  correlations.

Effectively communicate scientific findings, project progress, and key insights in project team meetings, department meetings, and discussions with key stakeholders to drive decision-making and inform strategic goals.

Knowledge and Skills:

Familiarity with omics datasets (transcriptomics, proteomics, secretomics, etc.).

Experience with scripting (Python and/or R/Bioconductor).

Demonstrated ability to work effectively in cross-functional teams and collaborate across disciplines.

Self-motivated, organized, and innovative, with excellent communication and presentation skills.

Proven ability to troubleshoot and solve complex biological and technical challenges in a fast-paced, dynamic environment.

A passion for advancing toxicology research to improve drug safety and transform the lives of patients.

Education and Experience:

Ph.D. (or equivalent degree) in toxicology, cellular biology, immunology, biochemistry, biophysics, or related disciplines with 0-3 years of relevant postdoctoral employment experience, or a Masters degree and 3+ years of experience or a Bachelors degree and 6+ years of experience

Strong expertise in developing and working with 3D organoid models, organ-on-a-chip technologies, and/or co-culture systems, particularly involving primary epithelial cells and immune cells.

Proven experience in designing and optimizing cell-based assays for disease modeling and/or evaluating mechanisms of toxicity.

Expertise in immune cell biology and co-culture models for studying immune-mediated toxicities.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
