We are seeking a scientist to join the AD team within the Advanced Delivery Systems (ADS) organization in Boston, MA. Reporting to the Senior Advisor, Bioassay Development, this individual will develop, implement, and execute bioassays supporting formulation/process development, in-process monitoring and product developability studies. The successful candidate will collaborate closely with cross-functional teams and bring self-motivation, independence, and strong hands‑on bench skills.

Responsibilities

• Develop and implement assays to characterize LNP drug product potency, mRNA cargo, and process‑and‑product‑related impurities.
• Conduct sample testing using a variety of technical platforms (e.g., cell‑based potency assays, flow cytometry, qPCR, ELISA).
• Evaluate assay performance to ensure data reliability and coherency for making critical, data‑driven decisions (e.g., in‑process monitoring, lot release, stability, comparability).
• Identify and troubleshoot complex analytical issues and propose effective, scientifically sound solutions.
• Work closely with cross‑functional teams to ensure analytical deliverables meet project timelines and program needs.
• Analyze and interpret experimental data, present findings to stakeholders, and make clear and actionable recommendations to the project team.
• Author test protocols, qualification reports, and other technical documents.
• Develop lifecycle management of reference materials and critical reagents and equipment to meet operational requirements.
• Track and recommend innovative bioassay techniques to address challenging analytical issues based on emerging scientific insights and program needs.

Basic Qualifications

• Bachelor's or Master's degree in molecular biology, biochemistry, or a related biological science, with 3-6 years of industry experience in bioassay development.
