Our Values - Our culture is our DNA. it defines our mission, our goals, how we operate and communicate on a day to day basis, and how we attract and hire great talent:

  • Be customer obsessed.

Everything begins here. We only succeed if consumers and retailers succeed.

Faster, better, cheaper for the customer. 

  • Move fast.

Build, iterate and learn quickly - always think of the automated solution first. 

A slow decision is worse than a wrong decision. 

  • Own it.

Think big, start small and power through problems to get it done.

A small group of committed people can change the world.

  • Be open.

Build open, honest and respectful relationships with each other. 

Transparency and integrity builds trust.

  • Win together.

Great work cannot be achieved alone. Bring the humility and leave the ego at the door.

It’s better to have a hole than an arsehole.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
