Manifold Bio is a platform biotechnology company pioneering AI-guided protein design and massively multiplexed in vivo screening to unlock tissue-targeted medicines and organism-scale models of living systems. Using proprietary molecular barcoding technology, we screen hundreds of thousands of protein designs simultaneously in living systems, producing in vivo-validated datasets at a scale no one else can match. The datasets power our computational models, which leads to better drug designs, creating a flywheel that gets stronger with every campaign. Our team of protein engineers, biologists, and computational scientists works across this full stack to pursue programs both internally and with leading pharma companies.
Position
We are seeking a highly-motivated In Vivo Pharmacology Senior Research Associate who thrives in a fast-paced and creative environment to push the capabilities of our multiplexed in vivo drug discovery platform. Together with senior researchers, you will play a critical role in executing in vivo studies to support internal research projects. This is a hands-on role and you should have extensive experience in multiple aspects of in vivo pharmacology including dosing, necropsy, perfusion, tissue collection and sample processing, among others. The ideal candidate must be able to work effectively both in a collaborative setting and independently.

We value different experiences and ways of thinking and believe the most talented teams are built by bringing together people of diverse cultures, genders, and backgrounds.

Manifold Bio is positioned to be the leading tissue-specific medicines company.
We’ve built the first high-throughput in vivo (HTV) discovery engine - combining massively multiplexed in vivo screening and AI-powered design to create targeted biologics. Our engine sculpts pharmacokinetics, biodistribution, and other key properties of biologics directly in living systems, solving previously intractable challenges for tissue-specific delivery.
By generating rich, scalable datasets in vivo, Manifold Bio is unlocking AI’s full potential to design targeted, effective therapeutics, and accelerate their path to patients.
