About Neion Bio
Neion Bio is harnessing nature’s best molecular factory, the chicken egg, to make medicine affordable, accessible, and resilient. We turn farms into medicine factories using cutting edge genetic engineering and stem cell technology. These “living bioreactors” are fully autonomous 3D biomolecular printers that operate on existing industrial-scale infrastructure. Our platform can rapidly and scalably produce almost any protein, provide national resilience to drug shortages and de-risk complex supply chains, and ultimately take advantage of novel biological environments to solve unmet medical needs. Biomanufacturing, reinvented. Medicine, democratized.
Role Summary
We are looking for a talented analytical scientist to lead analytical development and product characterization for monoclonal antibodies and other biologics produced using Neion Bio’s platform.
Working alongside our process development scientists, this individual will develop and implement analytical strategies to characterize product quality, guide process development, and support comparability, technology transfer, and regulatory submissions. The role will span physicochemical, structural, and functional characterization, including glycosylation, purity and aggregation, binding, and potency assays. The successful candidate will be responsible for in-house development and managing external programs.
Key Responsibilities
Develop and execute analytical strategies for monoclonal antibodies and other therapeutic and non-therapeutic proteins from early development through clinical manufacturing
Partner closely with process development scientists to characterize product and process-related variants, guide purification development, and establish relationships between process parameters and product quality
Develop, optimize, and perform selected analytical methods in-house, including assays for protein concentration, purity, aggregation, charge variants, identity, binding, and biological activity
Lead analytical characterization of critical quality attributes, including:
Glycosylation and other post-translational modifications
Primary and higher-order structure
Purity, fragmentation, and aggregation
Charge heterogeneity
Target and Fc receptor binding
Cell-based potency and effector-function assays, including ADCC
Design analytical comparability studies evaluating Neion-produced proteins against reference products and across process changes, scales, and manufacturing sites
Select and manage CROs and specialized analytical laboratories, including drafting scopes of work, evaluating technical capabilities, managing timelines and budgets, and overseeing study execution
