Arcellx

We are a biotechnology company with one specific mission: Advance humanity by engineering cell therapies that are safer, more effective, and more broadly accessible.

Reimagining cell therapy
Powered by our novel D-Domain technology and paired with our transformative ddCAR and ARC-SparX platforms, our unique approach to cell therapy aims to supercharge how the world treats cancer.

Delivering results with every cell of our being
From the very beginning, our team has been united to destroy cancer and challenge convention—while ensuring patients stay at the forefront.

Mission-critical collaboration
Every day, we are building a more purposeful, empathetic team ready to work together to spearhead change and transform the fight against cancer. Join us.

Welcome to Arcellx

At our company, you'll find a passionate group of people dedicated to changing the world through the fight against cancer. If you want to contribute to work that can transform lives, and if you share our values of collaboration, character, audacity, originality, and determination, then we encourage you to apply to one of our open positions below. 

Having a team made up of individuals with diverse backgrounds and perspectives makes our company stronger. We encourage applicants to apply for roles they are generally qualified for even if they don't meet all the preferred qualifications. Your unique experience could be just what we're looking for! 

Arcellx recognizes that flexibility in workweek scheduling is critical to each individual being their most productive, and we support it. At the same time, we seek team members who thrive working alongside colleagues, and who are willing to work on site in either our Maryland or California locations. 

Thank you for your interest in our company. We can't wait to meet you!

In addition to being able to work on transformative novel technologies that can destroy cancer and change the lives of people around the world, competitive salaries, and well-appointed facilities, life at Arcellx offers benefits, perks, and a sense of community.

100% health insurance premium coverage

We know how important health care is. It’s our business. Which is why we provide full healthcare premium coverage for our employees, so we can all focus on further improving patient health through our cell therapy platforms.

3 Day weekend every month.

We know that having time to disconnect is essential to productivity and mental health. We make sure that in months where there's not an official holiday, we provide a company-wide 3-day weekend with an "Arcellx Day" either on a Monday or a Friday.

Strong sense of community.

Nothing makes us more inspired than engaging with our community and our cause. This year nearly two-thirds of the Arcellx community joined in the Multiple Myeloma Foundation’s annual 5K run in Washington, DC, an amazing turnout where all the employees who participated received customized Arcellx running shoes.
