Experience/ Skills:

• Molecular biology techniques, including construct design, DNA isolation and purification, and assembly-based cloning are required.
• Protein expression in HEK and/or CHO cells is required. Experience with yeast and insect expression platforms is advantageous.
• Protein purification techniques are required, including a basic understanding of FPLC, HPLC, gravity drip columns, and a range of affinity and capture technologies including SEC, IEX, mixed-mode, etc.
• An understanding of biophysical characterization of proteins is important. Relevant competencies may include but are not limited to, RP, IEX, SEC chromatography, Biacore & Octet, and HR-MS of proteins.
• Medium- and high-throughput protein expression is not required but advantageous.
• Outstanding organizational skills and experience in preparing scientific and technical documents are important.
• Attention to detail: Demonstrated excellence in designing and conducting hands-on experiments, organizing and managing projects, and maintaining meticulous documentation.
• Motivation and creativity: Highly motivated and creative with a devotion to project goals and timelines.
• Collaborative skills: Proficient in collaborating and communicating effectively with colleagues and management teams.
• Ability to meaningfully contribute to scientific discourse.
