AI Research Scientist

This AI Research Scientist will lead the design and build biological foundation models that learn shared representations across Quiver's large-scale all-optical electrophysiology and multi-omic datasets. The role also involves hands-on development of signal and image processing for our proprietary optical electrophysiology data. The candidate will both lead and directly implement projects that integrate complementary data streams (e.g., transcriptomics, high-content imaging, clinical datasets, etc.) using deep representation learning, contrastive objectives, transformer architectures, and multi-modal fusion to build predictive models of disease biology and drug mechanism. The successful applicant will work as part of a small, close-knit team at the hub of Quiver's scientific programs. This position will actively mentor team members and set technical direction alongside contributing production-quality code and models to derive actionable insights from a broad range of relevant biomedical data modalities, including the company's proprietary all-optical electrophysiology data and other genomics/omics and imaging data sets. The ideal candidate will be a strong computer scientist with deep expertise in representation learning, foundation model architectures, and multi-modal data alignment, with a demonstrated track record of leading teams while remaining deeply hands-on in coding, experimentation and system development, and a passion for applying technology to healthcare-related problems.

About Quiver Bioscience

Quiver Bioscience is a technology-driven company established to create transformational medicines for the brain. We combine proprietary single-cell functional assays with other multi-modal measurements to discover new biology and new drug targets. We take advantage of cutting-edge AI/ML to build the world's most information-rich maps of neuronal function to drive our drug discovery programs. This position is based in Cambridge, MA, with the expectation of on-site presence 3-4 days per week to support lab integration, team meetings, and collaborative project work. Fully remote applicants will not be considered.

Responsibilities and Duties

• Design, lead and directly implement computational pipelines for feature engineering and data integration for scientific data analysis.
• Lead collaboration efforts while actively contributing to system architecture and implementation with internal and external teams responsible for production AI systems (e.g., LLM-based tools, agentic workflows).
• Provide input on system design, identify opportunities for new capabilities, and help define and integrate modeling workflows into user-facing applications.
• Develop machine learning models to learn and align shared representations across heterogeneous biological datasets (e.g., time-series electrophysiology data, imaging, and perturbation assays).
• Build and maintain scalable systems for embedding generation, storage, and retrieval (e.g., vector-based search, nearest-neighbor lookup) to support downstream analysis and querying.
• Own and develop rigorous evaluation frameworks and benchmarks for cross-modal embedding quality, including alignment metrics, retrieval precision, and biological plausibility checks against known drug-target and gene-pathway relationships.
• Partner closely with cross-functional wet-lab teams to design active learning cycles where model predictions suggest and prioritize validation experiments.
• Lead by example in the development and deployment of AI/ML systems, ensuring best practices in reproducibility, version control, performance optimization, and documentation within a modern cloud-based environment.
• Contribute to the development of data and machine learning pipelines, including implementation, evaluation, optimization, and maintenance of models and associated workflows.
• Balance team leadership with individual technical contributions, relationships, and work priorities to comfortably operate independently to make an impact.
• Utilize excellent interpersonal skills to build consensus, share insights with relevant stakeholders, deliver interpretable data products, and serve both business and scientific goals of the company with your work.
