Staff Engineer, Content Systems

Company Description

Overview 
SPANX isn’t your average company. We revolutionized an industry by challenging the status quo and putting the customer first. You might know the story: our founder, Sara Blakely, who needed the right thing as a base layer to feel 100% in white pants, so she cut the legs off a pair of tights and Spanx was born. The spark of that origin is the fuel for our future. We grew up in shapewear. But we’ve graduated. For 25 years (yep, we're old enough to rent a car now), we've been experimenting, innovating, and occasionally banging our heads against the drawing board. And we will never stop obsessing about what women who are out there doing their thing deserve. Because we are those women. And we’re honored to create on behalf of us all.

We make elevated essentials with confidence built in. Essentials for layering underneath or wearing out loud, for “just-between-us” and “where'd you get that?” For everything you've got planned (and don't). Because what you put on can change how you show up. And if its' not working for you, it's got no place in your closet. Or on your body. Creating items that’ll make you feel great is a matter of the heart—and the lab. In every Spanx product is technology we design and build to highlight, complement, and form your look, just the way you like it. SPANX design and technology help make sure what you see in the mirror reflects that feeling of feeling your best (you know the feeling?). We are a high-growth, innovative and ambitious company and we are embarking on an exciting trajectory of both digital and international expansion.
