Additionally, they will be responsible for documentation of expression conditions and results in internal databases and electronic lab notebook systems. This is an onsite role. Qualifications MS or equivalent with 2+ years of relevant experience, or Ph.D. This position requires 2+ years of experience working with insect cell lines and baculovirus expression of recombinant proteins. Additional experience working with recombinant protein expression in mammalian cells (e.g. HEK293) is a plus. Industry experience preferred with exemplified ability to overexpress milligram amounts of protein for structural and functional studies for multiple protein classes. Highly proficient in maintaining insect cell and mammalian cell cultures. Excellent knowledge and high degree of familiarity with all steps in baculovirus expression of recombinant proteins, including clone design, generation and purification of bacmids, raising and titering of baculovirus, conducting MOI studies, cell culture of Sf9 and/or Tni/Hi5 cells, and harvesting of biomass on the scale of 1 L – 20 L. Strong working knowledge of protein characterization steps, including SDS-PAGE analysis, size exclusion chromatography, and/or thermal stability (e.g. nanoDSF). Must be able to lift 50+ pounds comfortably. Familiarity with multiplexed/automated microscale purification technologies (e.g. magnetic beads) is desirable. Previous experience expressing multi-subunit protein complexes is a plus. Past experience troubleshooting difficult protein expressions for a variety of target proteins is a plus. Past experience purifying recombinant proteins (e.g. affinity chromatography, ion exchange, or size exclusion chromatography) is a bonus. Able to work in dynamic, fast-paced environment with experience prioritizing work across multiple projects. Detail-oriented with strong record keeping skills.
