Ultimately, this group generates the data packages and clinical biomarker strategies required to drive crucial pipeline Go/No-Go governance decisions and patient stratification for Neurodegeneration (Alzheimer’s, Parkinson’s) and Pain programs. Reporting to the Neuroscience Biomarker discovery lead at our company, this individual will play a pivotal role in assay development and generating data in support of biomarker strategies from preclinical models to human clinical and observational studies for Alzheimer's disease (AD), Parkinson's disease (PD) and Pain. This is a lab-based position located in Boston. You will lead the design, development, optimization, and automation of complex, high-dimensional assays to process human biofluids and tissues, generating the robust datasets required for pipeline Go/No-Go decisions and patient stratification.

Primary Responsibilities

• Plan, design, execute and deliver high-quality biomarker datasets from observational human and preclinical samples in support of pipeline programs in Neuroscience at our company.
• Serve as a subject matter expert and lead the design, development, and qualification of fit-for-purpose biomarker methods. This includes driving our workhorse ultra-sensitive immunoassays while spearheading the adoption of high-plex NGS-based proteomic platforms (e.g., Olink).
• Partner closely with data scientists within and outside the team to ensure automated workflows yield high-fidelity data suitable for mixed-effects modeling and multi-omics integration. Collaborate with Mechanistic Validation scientists to support in vitro, in vivo readouts.
• Work on-site in the lab and summarize data and status of results with internal and external partners.
• Participate and contribute to the generation of data packages that enable key governance decisions for pipeline programs.
• Take the lead in identifying, piloting, and automating novel high-throughput methodologies for biomarker discovery (e.g., implementing robotic liquid handling, flow-cytometry based immune-cell profiling using single cell sequencing in human and mouse samples, or extracellular vesicles).

Required Qualifications

• Master’s in molecular biology, Biochemistry, Neuroscience, Immunology, Neurology, or related STEM fields with minimum 6 years of relevant industry experience OR PhD in molecular biology, Biochemistry, Neuroscience, Immunology, Neurology, or related STEM fields with hands-on relevant experience.
