As a Scientist, your mission is to execute protein and molecular biology engineering strategies to advance projects within Arcellx’s Discovery group. Engaging with a cross-functional team in a fast-paced environment, you’ll identify and develop Arcellx’s lead therapeutic candidates. Our potentially life-saving treatments would not exist without the work of our talented Discovery scientists - this role will have a tremendous impact on our pipeline and ability to deliver novel and effective drugs to patients.    

The “Fine Print” – What You’ll Do

• Work with an interdisciplinary team of scientists to design, engineer and express recombinant proteins for use in the discovery and development of cancer therapies.
• Design, construct and evaluate expression plasmids. Perform transfections, transductions, phage and yeast display enabled selections & screenings, binding kinetic assessments and flow cytometry as needed.
• Develop new methods, technologies and processes when necessary for project.
• Exercise significant technical discretion in the design, execution and interpretation of experiments.
• Communicate progress and project recommendations to team members.

Skills and Experience We Look For

• Either BS or MS in the life sciences (e.g., biology, genetics, biochemistry, chemistry, chemical engineering, bioengineering) with 4-8 years post-degree lab experience or PhD in the life sciences with 0-3 years post-degree experience.
• Must demonstrate mastery of molecular biology methods, including primer design, PCR, gel electrophoresis, expression construct design cloning and sequence analysis.
• Preferred skills include: methods for the characterization of recombinant protein quality and binding, lentiviral vector transductions, transient transfections and flow cytometry.
• Preference for experience in drug development, oncology and immunology.
• The ability to independently plan, organize, and prioritize work activities. The ability to work collaboratively in interdisciplinary teams.
