Position Overview

Leads in the purification and analytical characterization of proprietary polymer-protein or polymer-peptide conjugates.

Leads in the planning and execution of scientific experimentation to support the protein therapeutic pipeline for the company. Applies knowledge of protein chemistry, mass spectrometry, and protein-protein interaction techniques, to design and develop appropriate data sets that support company initiatives. Develops analytical methods for Research and to support tech transfer for manufacturing. Manages workflow among a complex set of projects, collaborators and sites. This position contributes to and supports the company's research and development efforts to create high value therapeutics to address unmet medical needs. Works on complex problems in which analysis of situations or data requires an in-depth evaluation of various factors. Exercises judgment within broadly defined practices and policies in selecting methods, techniques and evaluation criteria for obtaining results. May determine methods and procedures on new assignments. Serves as an in-house consultant. May act as spokesperson on corporate research/technology/development and advise senior management. Leads in the use of professional and scientific concepts to contribute to the development of company concepts and principles to achieve objectives in creative and effective ways.Synthesizes multiple data sources and draws general, non-obvious conclusions. Defines complex problems, develops approaches and develops experiments with sound judgment. Key contributor in the development of IP. Interfaces with various departments, customers and partners. Puts work practices in context with larger team and participates in the implementation of change when required. Plans and coordinates activities with other team members. Writes and/or approves complex reports and protocols. Identifies needs for additional resources. Designs protein or peptide conjugation strategies and independently synthesizes and analyzes conjugates to support the protein therapeutic pipeline. Develops and optimizes conditions for chemical conjugation, purification and analysis of polymer-protein or polymer-peptide conjugates. Works on multiple projects simultaneously, where coordination of efforts among various sites and attention to critical timelines is essential to success. Critically analyzes complex data and interprets experimental results. Works directly with biology and pharmacology teams to characterize the in vivo and in vitro activity of various polymer-polypeptide conjugates. Interfaces, works with and supports various departments at multiple locations. Plans and coordinates activities with other scientists, team members and the patent department. Develops analytical methods for characterization, lot release and technology transfer. Identifies and coordinates access to additional resources. Writes complex reports and protocols.
