Our Values

Arcellx corporate value card titled 'Character'

Be authentic. Always do what’s right.

“It is only with the heart that one can see rightly, what is essential is invisible to the eye”

– Antoine de Saint-Exupéry

Teams are built on trust and character is its foundation. We value doing the right thing as much as we value delivering results.

Arcellx corporate value card titled 'Originality'

Bring your unique value to the table. Respect others’ unique value.

We are strongest and we deliver game-changing results when we bring our whole self to work. We value the life experiences of all our team members and appreciate how their diverse perspectives enrich our culture and contribute to our success.

Arcellx corporate value card titled 'Determination'

Get better every day. Never give up.

Our collective drive to destroy cancer provides us the energy and perseverance to meet any challenge that stands in our way. Every obstacle is an opportunity. Through overcoming challenges and a commitment to personal development, we aim to get better every day, individually and collectively.

Arcellx corporate value card titled 'Audacity'

Challenge the status quo. Have a growth mindset.

Dream big. Act like a founder. Obsess over the customer experience. Think outside the box. This is your company. Together let’s change the world.

Arcellx corporate value card titled 'Collaboration'

No job is too small. We win together.

There’s little in life of significance that one can accomplish on their own. No one is too big for any job because we operate with mutual respect for everyone on the team and know that every team member has an important role to play in our success. We support one another’s growth. Together we can go the distance.


At Arcellx, we know that the transformative scientific and technological breakthroughs that allow us to reimagine cell therapy would not be possible without a purposeful, empathetic approach from an incredible, dedicated team.

At Arcellx, our workplace culture is rooted in trust: we trust each other as individuals and as teams with meaningful work. I love partnering with my teammates on large-scale assignments that help the company achieve its important goals.

Arcellx team member Jenny Mu, Associate Director

I am a poster child for growing within Arcellx. My leader knew how to build a team of people by recognizing raw talent – the diamond in the rough – and investing in developing those individuals through coaching and teaching.
