•    Detailed experimental planning for the development of process (not only individual unit operations), execution and analysis.
•    Support tech transfers with review of study plans, process descriptions, person-in-plant, data analysis, etc.
•    Design of labs and equipment lay-out.
•    Equipment qualification, maintenance and calibration.
•    Electronic lab notebook systems.
•    Viral clearance studies.
•    Management of scientists (in addition to daily supervision): coaching, performance reviews, career development.
•    External publications and presentations. 


SKILLS, KNOWLEDGE AND ABILITIES REQUIRED
•    M.S. or Ph.D. in biochemistry, chemistry, chemical engineering or biological sciences.

o    Lysis/extraction with detergents, use of surfactants.
o    Centrifugation.
•    Excellent record keeping in laboratory notebooks, and authoring of procedures, protocols, technical reports and presentations.
•    Hands-on experience with the operation of AKTA series of chromatography skids.
•    Scientific understanding and hands-on experience with HPLC, spectrophotometry, SDS-PAGE.
•    Quality Target Product Profile (QTPP) and Critical Quality Attributes (CQAs).
•    Manufacturing process risk assessments.
•    Statistics including tolerance intervals, practical significance tests (e.g. Two One Sided T tests), design and analysis of DOEs (e.g. with JMP), process monitoring (control charting).
•    In-process analytical control strategy.
•    Establishing process (operational) parameter set-points and ranges (Normal Operating Ranges (NORs), Proven Acceptable Ranges (PARs).
•    Change controls, deviation investigations.
•    Authoring of regulatory submissions (e.g. IND, BLA) CMC sections.

WORKING CONDITIONS AND/OR PHYSICAL REQUIREMENTS

•    Follow rules of Biological Safety Level 2 laboratories.
