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.

How You’ll Make a Difference
As an Associate Scientist in our Cell Biology group, you will have a direct impact on the Arcellx drug pipeline as a lab-based contributor, supporting one or more major projects. Our potentially life-saving treatments would not exist without the work of our talented scientists. Your contribution 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
- Handle, isolate and manipulate primary human immune cells (e.g. PBMC, BMMC, T cells and monocytes) and cultured cell lines.
- Produce research-scale lentivirus, analyze lentiviral quality, and determine viral integration into cell lines or primary human T-cells.
- Conduct complex immune assays including in vitro cell-based assays (e.g. cytotoxicity, proliferation, degranulation), multiplex assays (e.g. MSD) and live cell analysis (e.g. Incucyte).
- Flow cytometry acquisition and analysis to evaluate antigen expression and protein binding.
- Process blood and tissues from animal studies for analysis.
- Execute ELISAs (commercial kits and custom assays) to measure cytokines, proteins and/or other biomarkers.
- Utilize common software including GraphPad Prism, Word, PowerPoint, Excel, Outlook, and Flow Cytometry Analysis Software (FlowJo) to analyze, record and present your results.
- Communicate detailed observations on experiments and assist in the preparation of technical reports, summaries, and protocols.
- Work both independently and collaboratively, and effectively plan, organize work activities, and prioritize task completion.
- Assist in maintaining laboratory consumables.
Skills and Experience We Look For
- BS degree with 2+ years of full-time laboratory experience or thesis-based MS degree.
- Familiarity with one or more of the following areas: cell therapy, T-cell biology, tumor immunology or the use of biologics in anti-cancer therapy.
- Expertise in manipulating immune cells, particularly T cells, including purification, transfection/transduction, activation and expansion.
- Proficiency with complex immune cell assays including multiparameter flow cytometry, in vitro cell based assays, and multiplex assays.
- Ability to effectively multitask and collaborate across multiple projects in a fast-paced cross-functional environment.
- Commitment to ethical scientific investigations and rigorous experimental methods.
