Scientist, Cell Biology

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.

• Embrace the challenge: We deliver exceptional results by working with shared determination and a commitment to doing what’s right.

How You’ll Make a Difference

As a Scientist within our Cell Biology group, you will have a direct impact our drug pipeline as a lab-based contributor and functional area lead within the project setting. Our potentially life-saving treatments would not exist without the work of our talented scientists. Your work as a member of our experienced cross-functional team will drive discovery, characterization, and optimization of novel cell-based therapies.

The “Fine Print” – What You’ll Do

• Contribute to one or more pipeline programs, working collaboratively with cross-functional teams to ensure the timely generation and dissemination of critical program data to enable data-driven decisions.

• Design and execute experiments independently with minimal supervision, as well as effectively plan and organize work activities and prioritize task completion.

• Serve as a functional area lead within a project setting; helping to derive timelines, plan, and execute to help achieve project goals.

• Stay up to date with relevant technical and intellectual scientific expertise in tumor biology and cancer modelling, particularly as it relates to CAR-T cell biology or other cell-based therapies.

Skills and Experience We Look For

• Candidates with a master’s degree and 4-6+ years research experience within the pharmaceutical industry or a PhD-level scientist from a relevant field and 0-2 years industry experience.

• Specific backgrounds of interest are:

• Chimeric Antigen Receptor (CAR) T-cells or alternative cell-based cancer therapeutics

• T-cell signaling and/or cytokine signaling and cytokine biology

• Solid Tumor Immunology (Tumor Infiltrating Lymphocytes, Myeloid Derived Suppressor Cells, Tumor Associated Macrophages, Regulatory T-cells)

• Expertise in manipulating immune cells, particularly T cells, including purification, transfection/transduction, activation and expansion.

• Experience with in vivo models of human cancer, including cell line derived xenografts or patient-derived xenografts.

• Expertise in complex immune cell assays including multiparameter flow cytometry, in vitro cell based assays (e.g. cytotoxicity, proliferation, degranulation), live cell analysis, and multiplex assays.

• Familiarity with methods to pre-clinically assess efficacy, specificity, and safety of CAR-T cells or other novel immuno-oncology agents.

• Commitment to ethical scientific investigations and rigorous experimental methods.

• Ability and desire to multitask and function in a fast-paced entrepreneurial environment.

• Interpersonal skills that promote a collaborative and productive lab environment.
