An Insider's view of Chewy

What’s the vibe like in the office?

Fast paced! We work in "doggy-years" here. It's a place where talent and hard work is valued and where team members can think big and can bring their dreams to life.

Greg

Senior Technical Recruiter

What projects are you most excited about?

I'd say our new onboarding program, which educates and immerses Chewy’s new hires in our business, mission, and Operating Principles. I hope new Chewtopians walk away from our revamped onboarding experience with a deeper understanding of what makes Chewy special and that it helps them build connections with their fellow new team members.

Victoria

Senior Talent Manager

What are some things you learned at the company?

Creating a work environment that is accessible to everyone attracts a diverse talent pool and unlocks talents and skills that might not be available otherwise.

Mark

Sr. Accessibility Program Manager

How do you make yourself accessible to the rest of the team?

Aside from the standard 1x1s and team meetings: 24/7 via text, email, chat, voice and during business hours by walking around the office engaging in conversation, listening to current challenges and proposed solutions.

Mike

VP, Software Engineering

What’s the vibe like in the office?

My favorite Operating Principle here at Chewy is “Debate Openly, Commit Fully.” It makes me comfortable having passionate disagreements with my coworkers about a project when appropriate, knowing that we can have a (zoom) beer later that day and feel OK about it. Every company strives for that culture, and it's a part of our DNA at Chewy.

Senior Product Manager
