Principal Scientist, Translational Immunology & High-Throughput Precision Biomarkers

Job Description

The•Data, A.I. and Genome Sciences Department•is-seeking-a highly motivated and passionate•Principal Scientist•to join our•Genome Science•research team. In this role, you will-develop and execute large-scale translational-immunology studies-on-human-biospecimens-in-support of•companion diagnostic (CDx) development•and biomarker discovery.

In this role you-will apply a range of immunology and genomics approaches-at scale, including•PBMC isolation,•immune-cell activation assays,•cytokine profiling,•flow cytometry, and•single-cell RNA sequencing, to characterize immune cell interactions and-identify-biomarkers associated with treatment response.-

The ideal candidate will have experience in•biomarker assay development,•cytokine profiling,•immune-cell characterization,•flow cytometry,•and preparing human biospecimen samples for-multi-omics data-generation.-Candidates who have-demonstrated-the ability to design-and-execute-high throughput-translational studies-with human biospecimens at-scale and-leveraging-automation to enable robust data generation are strongly encouraged to apply.-

This role supports•biomarker discovery•within the•Discovery Immunology•therapeutic area and is based at our company's Research Labs site in Cambridge, MA. As a member of this team, you will have the opportunity to collaborate with and lead cross-functional teams of experimental biologists, data scientists, and Discovery Immunology stakeholders to advance biomarker discovery and translational science.-

Key Responsibilities: -

• Lead-translational-immunology-studies-leveraging-human biospecimens-to support biomarker discovery and companion diagnostic (CDx) development in Discovery Immunology.-
• Design-and execute-hands-on laboratory-experiments-for large-scale studies-using PBMCs, immune-cell activation assays, cytokine profiling, flow cytometry, and single-cell RNA sequencing.-
• Develop and-optimize-biomarker assays and workflows to characterize immune-cell-interactions and-identify-response-associated biomarkers.-
• Design and execute experiments for integration of multi-modal data types such as-bulk transcriptomics, single-cell transcriptomics, flow cytometry, cytokine assays, and other multi-omics platforms to generate actionable biological insights.-
• Partner with experimental biologists, data scientists, and cross-functional Discovery Immunology stakeholders to advance translational hypotheses and biomarker strategies.-
• Translate mechanistic biology into clinically relevant hypotheses that inform patient stratification, target engagement, and biomarker-driven decision-making.-
• Lead study planning, experimental design, data interpretation, and presentation of findings to internal stakeholders and leadership.-
• Ensure scientific rigor, reproducibility, and quality in all biomarker discovery activities.-
• Evaluate emerging technologies and analytical approaches to strengthen translational immunology capabilities.-
• Collaborate-closely with experimental biologists, automation engineers, computational scientists, data analysts, AIML data scientists and therapeutic area subject matter experts to address biological questions, develop experimental strategies, and execute project plans.--
• Mentor and guide junior scientists and contribute to the growth of the Genome Science team.-
• Contribute to scientific publications, internal reports, and presentation materials as needed.-

Required Qualifications: -

• PhD in Immunology, Biology, Molecular Biology, Cell Biology, Biological-engineering-or related life sciences discipline with 8+ years of industry or pharma research, academia,-or a combination of both-
• Strong background in translational immunology, biomarker discovery, and human-biospecimen-based research.-
• Hands-on experience with PBMC isolation,-assay development using primary immune cells,-immune-cell activation assays, cytokine profiling, and/or flow cytometry.-
• Experience with bulk and/or single-cell transcriptomics, including experimental design-and-data interpretation.-
• Demonstrated-expertise-in biomarker assay development, optimization, and application in translational studies.-
• Experience-generating-multi-omics datasets to-enable-biologically meaningful and clinically relevant insights is preferred.
• Proven ability to design, execute, and interpret complex studies that connect mechanistic biology to clinical hypotheses.-
• Strong analytical, problem-solving, and scientific communication skills.-
• Ability to lead scientific projects and collaborate effectively with cross-functional teams.-
• At least 1-2 years' experience of direct people management experience.-
