Job description

Biomarker Lead
The Biomarker Lead will be accountable for biomarker planning and execution across one to two clinical programs, with a focus on programs approaching or in the clinic. This includes designing biomarker plans for each program, identifying appropriate bioassay labs/CROs, managing assay transfer and validation studies, and ensuring biomarker data are ingested, tracked, QCed, and integrated efficiently.

  • Develop and oversee biomarker plans for each clinical protocol.
  • Identify and qualify bioassay labs/CROs for biomarker assays
  • Lead assay transfer from Translation biology teams to bioassay labs/CROs, ensuring validation and qualification.
  • Oversee testing at bioassay labs/CROs, ensuring quality, compliance, and adherence to protocol requirements.
  • Collaborate with Clinical Development, Clinical Operations, Translational Biology, Data Management, Biostatistics, and Regulatory to ensure biomarker deliverables align with clinical program needs.
  • Provide updates on biomarkers to internal stakeholders.
  • Work with Translational Biology and Clinical Development colleagues to analyze biomarker data and test key program hypotheses.

Qualifications
  • PhD with postdoctoral training in Life Sciences, Cell Biology, Molecular Biology, Immunology, or a related field.
  • 4-5 years of industry experience in a clinical setting, in clinical biomarkers, translational medicine, or a related function within biotech/pharma.
  • Proven expertise in assay transfer, validation, and qualification with CRO and lab oversight experience.
  • Knowledge of biomarker assay platforms (flow cytometry, IHC, NGS, proteomics, ligand binding assays) and their clinical application.
  • Excellent organizational, cross-functional leadership, and communication skills, with the ability to manage multiple workstreams across one to two programs in a fast-paced environment.
  • Oncology experience strongly preferred. Immunology and/or neuroscience experience considered upside.
  • Experience with development of companion diagnostics (CDx) considered a plus.

This position is classified as exempt. The anticipated annual base salary range for candidates who will work in Watertown is $187,200 - $200,000. The final base salary offered to the successful candidate will be dependent upon several factors that may include but are not limited to the type and length of experience within the job, and other factors.
