MacroGenics' corporate culture promotes an atmosphere of innovation, open communication and teamwork where employees can see firsthand how they contribute to the success of the organization.

Summary of Position
The Sr. Scientist I/II - Pathology Assay Development will lead the development, optimization, qualification, troubleshooting, and transfer of tissue-based biomarker assays supporting MacroGenics' antibody-drug conjugate (ADC) and immunotherapy programs from discovery through IND-enabling studies and early clinical development. The role will focus on single-plex and multiplex immunohistochemistry (IHC), immunofluorescence (IF), in situ hybridization (ISH), digital pathology, and fit-for-purpose tissue biomarker workflows.

The Sr. Scientist I/II will work closely with the Senior Director of Pathology and cross-functional partners to generate robust, reproducible, and biologically meaningful tissue biomarker data that informs target selection, patient-selection hypotheses, translational strategy, safety assessment, and development decisions. Final pathologic interpretation, tissue biology assessment, and clinical-contextual interpretation will remain under pathology leadership.

Responsibilities and Job Duties
Tissue-Based Assay Development
* Independently develop, optimize, qualify, validate, and troubleshoot single-plex IHC, multiplex IHC/IF, and ISH assays using FFPE and frozen tissues.
* Design fit-for-purpose assay development plans, including antibody and reagent selection, titration, antigen retrieval, detection chemistry, controls, acceptance criteria, and reproducibility assessments.
* Evaluate assay specificity, sensitivity, dynamic range, precision, robustness, and tissue-context performance using appropriate positive, negative, isotype, cell-line, xenograft, and normal-tissue controls.
* Identify and resolve pre-analytical and analytical variables related to tissue collection, fixation, processing, sectioning, storage, staining platforms, and reagent performance.
* Develop and maintain tissue and cell-pellet control resources to support assay development and routine assay performance monitoring.
* Translate exploratory assays into qualified biomarker workflows suitable for nonclinical and clinical research applications.

Digital Pathology and Image Analysis
* Perform whole-slide image review, quality control, and quantitative analysis of tissue biomarker data.
* Partner with pathology leadership to ensure that digital outputs are morphologically appropriate, analytically sound, and aligned with the intended biological question.
* Evaluate and implement digital pathology tools and, where appropriate, AI/ML-enabled image-analysis approaches.

Translational Biomarker Support
* Execute tissue-based components of translational biomarker strategies defined with Pathology and Translational Medicine leadership.
* Generate target-expression, pharmacodynamic, mechanism-of-action, and tumor-immune microenvironment data across preclinical models and clinical specimens.
* Prepare publication-quality images, quantitative summaries, data visualizations, and technical interpretations for internal project teams, governance discussions, reports, and regulatory-supporting documents.

External Partnerships and Assay Transfer
* Coordinate assay development, qualification, validation, and sample testing with external CROs and central laboratories.
* Draft technical scopes of work, review protocols and validation plans, monitor study execution, assess data quality, and troubleshoot technical issues with vendors.
* Lead or support assay transfer, method bridging, and cross-site concordance activities to ensure consistent performance across internal and external laboratories.

Documentation, Quality, and Laboratory Operations
* Author and maintain assay development reports, validation summaries, SOPs, work instructions, protocols, templates, and technical best practices.
* Maintain organized assay records, raw data, digital image libraries, annotations, reagent inventories, and reference materials in accordance with applicable quality and data-integrity expectations.
* Support platform evaluation, laboratory workflow improvement, and adoption of new tissue-based biomarker technologies.
* Ensure timely delivery of high-quality data while managing multiple assays, program priorities, and vendor activities.
