• 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 intern, your mission is to develop assays and strategies to support product manufacture and next generation characterization for polyfunctionality of T cells within Arcellx’s Analytical Development group. This role will have a tremendous impact on our pipeline and ability to characterize the modified T cells as novel and effective drugs for patients. Our potentially life-saving treatments would not exist without the work of our talented scientists. 

The “Fine Print” – What You’ll Do 

• Commit to 6-10 weeks, full time (40 hours per week) paid internship.

• Professional and personal development curriculum throughout the program, including networking opportunities, workshops and panel discussions.  

• Final presentations of projects along with other interns at the conclusion of the program. 

• Work with an interdisciplinary team of scientists to develop and perform next generation characterization platform for all existing programs. 

• Learn and perform cell-based functional assays, including flow-cytometry based and live cell imaging methods to complete a project over the course of the program under the supervision of manager.  

• Process and analyze data using FlowJo, Live-cell imaging software, and other relevant analytical tools and keep accurate and complete lab documentation and electronic files.  

• Independently execute experiments while maintaining a collaborative and safe laboratory environment.  

• Participate in team meetings, present findings, and contribute to discussions on assay improvement and troubleshooting.  

Skills And Experience We Look For 

• Currently enrolled in university, pursing an undergraduate or graduate degree in life sciences (e.g. cell/molecular/cancer biology, genetics, immunology, biological engineering or related disciplines). 

• Proficiency in cell culture of diverse mammalian cell types.  

• Direct experience in performing cell-based assay development.  

• Familiarity with immunology and methodology of immune cell analysis. 

• The ability to independently plan, organize, and prioritize work activities and the ability to work collaboratively in interdisciplinary teams. 

• Effective writing and communication skills with ability to interact effectively with interdisciplinary scientists and engineers.  

Preferred Qualifications:  

• Proficiency in multi-color panels, intracellular staining and surface marker analysis. 

• Experience with FlowJo, GraphPad Prism, or other data analysis tools. 

• Knowledge of T cell biology, cytokine profiling, and immune response assays. 

• Prior experience in biopharma, biotech, or academic immunology research labs.
