Who We Are
Arcellx is a public, clinical-stage biotechnology company reimagining cell therapy by engineering innovative immunotherapies for patients with cancer and other incurable diseases. We believe that cell therapies are one of the forward pillars of medicine and our mission is to destroy cancer and advance humanity by developing cell therapies that are safer, more effective, and more broadly accessible.
Our team members are made up of talented innovators and dreamers working from our offices in Gaithersburg, Maryland, and Redwood City, California. At Arcellx, we hire exceptional people and create a fun, diverse, supportive, and informal environment that allows everyone to do their best work.

• Originality: Will bring your unique perspective to the table and respect a diverse set of views and backgrounds.

How You'll Make a Difference
As an Associate Scientist, you will use molecular biology, protein purification and characterization methods to support Discovery's protein engineering and technology development efforts. 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 other scientists to design, generate and characterize recombinant proteins to be used in cancer therapy discovery and development.
• Assist with selection and/or screening strategies used in protein discovery workflows employing phage display, yeast display, ELISA, BLI and flow cytometry as needed.
• Communicate detailed observations on experiments and assist in the preparation of technical reports, summaries, and protocols.

Skills and Experience We Look For

• Bachelor's or master's degree in the life sciences (e.g., biology, genetics, biochemistry, chemistry, chemical engineering, bioengineering).
• Minimum of 3 years of experience in a laboratory setting.
• Ability to work both independently and collaboratively. Ability to effectively plan, organize, and prioritize work activities.
• Must demonstrate proficiency with molecular biology methods, including primer design, PCR, gel electrophoresis, plasmid DNA preparation, cloning and sequence analysis using SnapGene or similar software.
• Preferred skills include those related to recombinant protein expression (e.g. transient transfection), purification (e.g. nickel and Protein A affinity chromatography) and characterization (e.g. ELISA, BLI, SDS-PAGE, protein quantitation and flow cytometry).
