Transfect and maintain various mammalian cell lines (e.g., HEK293, HTC116, Vero, HeLa) for transient and stable expression. Optimize expression protocols for high-yield protein production in both systems. Perform small- and large-scale protein expression experiments. Harvest cells and assist with downstream, protein purification (modern chromatography methods). Perform immunofluorescence microscopy to assess protein localization. Conduct SDS-PAGE gel analysis and western blotting, as part of routine experiments. Maintain detailed records of all experiments, protocols, and cell line inventories.

Basic Qualifications Bachelor’s degree in Biology, Biochemistry, Molecular Biology, or a related field. 2 years of hands-on experience with Sf9 and/or Hi5 cell culture and baculovirus-based protein expression. Proficiency in aseptic technique and routine mammalian cell culture. Familiarity with restriction enzyme cloning, western blotting, SDS-PAGE gel analysis, immunofluorescence microscopy, protein purification. Strong organizational and communication skills. Ability to work independently and collaboratively in a team environment. Preferred Qualifications Experience scaling up insect and/or mammalian cultures using flasks.
