What is a scientist IHC assay development?

Scientist IHC Assay Development jobs involve designing, optimizing, and validating immunohistochemistry (IHC) assays for use in research or clinical diagnostics. These scientists work with tissue samples and antibodies to detect specific proteins within cells and tissues, which can help identify disease markers or assess drug efficacy. They are responsible for troubleshooting protocols, analyzing results, and documenting findings while adhering to regulatory and quality standards. This role is critical in pharmaceutical, biotechnology, and academic settings for advancing scientific understanding and supporting diagnostic development.

What are the key skills and qualifications needed to thrive as a scientist in IHC assay development?

To excel as a Scientist in IHC Assay Development, you need a strong background in molecular biology, immunohistochemistry (IHC), and assay development, usually supported by a relevant degree such as a Ph.D. or M.S. Proficiency with IHC staining platforms, image analysis software, and laboratory information management systems (LIMS) is typically required. Attention to detail, problem-solving ability, and effective communication are essential soft skills for collaborating and troubleshooting in a research environment. These qualifications and skills ensure robust assay development, reliable data generation, and successful project outcomes in biomedical research.

What are some common challenges faced by a scientist in IHC assay development, and how can they be addressed?

A Scientist in IHC Assay Development often encounters challenges such as optimizing antibody specificity, minimizing background staining, and ensuring reproducibility across samples and batches. Addressing these challenges involves careful selection and validation of antibodies, thorough protocol optimization, and collaboration with pathologists and other scientists to interpret results accurately. Staying updated with the latest techniques and maintaining detailed documentation also play crucial roles in overcoming these hurdles and delivering reliable assay results.

Job description

SystImmune is a leading and well-funded clinical-stage biopharmaceutical company located in Redmond, WA and Princeton, NJ. It specializes in developing innovative cancer treatments using its established drug development platforms, focusing on bi-specific, multi-specific antibodies, and antibody-drug conjugates (ADCs). SystImmune has multiple assets in various stages of clinical trials for solid tumor and hematologic indications. Alongside ongoing clinical trials. SystImmune has a robust preclinical pipeline of potential cancer therapeutics in the discover and IND-enabling stages, representing cutting-edge biologics development. We offer an opportunity for you to learn and grow while making significant contributions to the company's success.
 
We are seeking a Scientist or Senior Scientist to lead and support immunohistochemistry (IHC) assay development for companion diagnostic (CDx) kits supporting oncology drug development. This role is responsible for end-to-end IHC assay development, including antibody selection, assay optimization, analytical validation, and clinical trial implementation, with a clear development path from RUO/LDT to IVD CDx commercialization.
The ideal candidate has strong expertise in pathology, IHC assay development, and CDx regulatory expectations, and can work effectively across R&D, clinical, regulatory, QA, and external CROs and central laboratories.
Key Responsibilities
IHC Assay & CDx Development
  • Lead development of IHC-based CDx assays, from biomarker discovery through assay optimization and validation.
  • Select and evaluate primary antibodies, detection systems, and staining platforms (e.g., Ventana, Dako, Leica).
  • Optimize assay parameters, including epitope retrieval, antibody dilution, detection chemistry, and staining conditions.
  • Establish scoring algorithms, cut-off strategies, and interpretation guidelines in collaboration with pathologists.
  • Support biomarker strategies for patient selection and stratification in clinical trials.

Analytical Validation & Performance
  • Design and oversee analytical performance studies, including:
    • Sensitivity and specificity
    • Precision and reproducibility (intra-run, inter-run, inter-site)
    • Accuracy and robustness
    • Linearity and limit of detection, where applicable
  • Prepare, review, and approve validation protocols, reports, and SOPs in alignment with CDx expectations.

Clinical Trial & Central Lab Support
  • Support implementation of IHC assays in clinical trials, including:
    • Central laboratory qualification and oversight
    • Pathologist training and alignment
    • Slide logistics, staining consistency, and scoring harmonization
  • Collaborate with clinical teams on sample strategy, feasibility studies, and biomarker cut-off justification.
  • Regulatory & Quality Collaboration
  • Work closely with Regulatory Affairs and Quality Assurance to ensure compliance with:
    • FDA CDx guidance (US)
    • NMPA/CDE requirements (China), where applicable
    • IVDR (EU), as relevant
  • Support preparation of regulatory documentation, including:
    • IDE/IND biomarker sections
    • CDx bridging strategies (RUO/LDT → IVD)
    • Analytical and clinical performance summaries
  • Ensure assay development aligns with QMS requirements, design controls, and document traceability.
Cross-Functional & External Collaboration
  • Serve as a technical subject-matter expert, interacting with:
    • CROs, central laboratories, and IVD partners
    • Antibody vendors and staining platform providers
  • Provide scientific input to project teams, governance meetings, and external collaborations.
  • Mentor junior scientists and contribute to team capability building, as appropriate.

Qualifications
Education
  • PhD in Pathology, Molecular Biology, Immunology, Oncology, or a related field
  • MS or BS with significant CDx or IVD industry experience may be considered

Experience
  • 3–5+ years of hands-on experience in IHC assay development, preferably in a CDx or IVD setting
  • Direct experience supporting oncology biomarkers and clinical trials
  • Experience across the CDx development lifecycle (RUO/LDT through IVD readiness)
  • Strong understanding of IHC scoring methodologies (e.g., TPS, H-score, CPS)
  • Familiarity with analytical validation and regulatory expectations for CDx
  • Demonstrated ability to work effectively in cross-functional teams

Soft Skills
  • Strong scientific rigor with excellent documentation and data interpretation skills
  • Ability to operate in a fast-paced, matrix environment
