• A minimum of 10 years of relevant experience in the pharmaceutical or biotechnology industry, with a substantial focus on molecular assay development and clinical biomarker support.
• Extensive hands-on experience with nucleic acid extraction, qPCR, next-generation sequencing (NGS), single-cell analysis technologies, and immunoassay platforms such as ELISA and Meso Scale Discovery (MSD).
• Demonstrated experience with tissue culture techniques and cell-based assay systems.
• Strong understanding of clinical assay development processes, including method development, analytical qualification and validation, and transfer to external laboratories.
• Proven ability to troubleshoot and independently resolve complex assay development challenges.
• Demonstrated ability to manage multiple projects and competing priorities in a fast-paced, matrixed environment.
• Excellent written and verbal communication skills, including the ability to clearly present scientific data to diverse audiences.
• Strong attention to detail and analytical rigor across experimental design, data analysis, and the authoring and review of validation reports.
• Strong interpersonal skills and a collaborative approach to problem-solving.

Nice To Haves

• Direct experience supporting oncology clinical trials with translational biomarker strategies.
• Familiarity with regulatory requirements and quality standards applicable to clinical assay development (e.g., CLIA, CAP, GCP).
• Expertise in additional molecular platforms such as digital PCR, RNA sequencing, or spatial transcriptomics.
• Experience with complex data analysis using bioinformatics tools.
• Experience with assay automation and high-throughput workflows.

Responsibilities

• Partner with translational research scientists, biomarker leads, and clinical operations teams to define assay strategies that support exploratory, predictive, and prognostic biomarker endpoints in oncology clinical trials.
• Design, develop, optimize, and qualify molecular and immunoassay-based clinical assays using technologies such as qPCR, next-generation sequencing (NGS), single-cell analysis platforms, ELISA, and Meso Scale Discovery (MSD).
• Provide hands-on technical leadership in the execution and troubleshooting of complex analytical workflows, and perform sample analysis in the Spring House laboratories as needed.
• Support tissue culture and cell-based functional assay activities to complement translational biomarker strategies.
• Manage and prioritize assay development activities across multiple oncology programs in parallel, ensuring timely delivery of high-quality data to support clinical decision-making.
• Analyze and interpret complex datasets generated from molecular and immunoassay platforms, and prepare clear, accurate reports and presentations for internal stakeholders and cross-functional teams.
• Review analytical protocols, reports, and raw data generated by team members to ensure compliance with internal standards and specifications.
• Maintain rigorous documentation in accordance with Good Laboratory Practices, including sample management, ELN entries, and end-to-end traceability of raw and analyzed data, in line with company SOPs and regulatory requirements.
• Evaluate and help adopt emerging assay technologies and platforms to strengthen the clinical assay development portfolio.
• Present research findings and assay development updates at team meetings, departmental seminars, and leadership reviews.
