Nice To Haves

• Experience with downstream protein workflows, including protein purification and characterization, protein folding, aggregation, post-translational modifications, and assessment of protein quality or function.
• Experience with suspension cell culture and scale-up workflows.
• Experience with multiple protein-expression modalities, such as antibodies, recombinant proteins, difficult-to-express proteins, or other biologically relevant targets.
• Additional languages.

Responsibilities

• Serve as a subject matter expert in protein expression workflows, especially transient protein expression in mammalian cell systems.
• Provide pre- and post-sales scientific support to customers.
• Deliver seminars, demonstrations, and internal and external training.
• Partner with customers to troubleshoot and resolve complex workflow challenges.
• Provide practical recommendations to optimize protein expression workflows.
• Connect protein expression workflows with downstream workflows such as protein purification, characterization, and analysis.
