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 Rockville, 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.

How You’ll Make a Difference

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.
• 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

• BS or MS in the life sciences (e.g., biology, genetics, biochemistry, chemistry, chemical engineering, bioengineering) with 5-8 years post-degree lab experience or PhD in the life sciences with 0-3 years post-degree experience.
• Demonstrated mastery of molecular biology methods, including primer design, PCR, gel electrophoresis, expression construct design cloning and sequence analysis.
• Ability to independently plan, organize, and prioritize work activities, and work collaboratively in interdisciplinary teams.
• Preferred skills include: methods for the characterization of recombinant protein quality and binding, protein display (phage, yeast and library preparation).
• Preference for experience in drug development, immunology or receptor biology.

Rewards at Arcellx

Our people are our greatest asset, and supporting their well-being is an essential part of delivering on our mission and impacting the lives of patients. Putting this belief into practice means offering strong compensation and benefits.

In addition to a competitive base salary, our compensation package includes an annual bonus based on company goals and an equity (RSU) grant. We do offer relocation assistance for roles if required.

Our market-leading benefits package includes: 100% coverage for medical, dental and vision for team members and dependents, unlimited vacation, a 3-day weekend every month, fully-paid parental leave for up to 6 months, tuition reimbursement, 401k employer contribution and more.
