Looking for a job to get you out of bed?

Casper ( is a global sleep company that launched in 2014 with an obsessively engineered, outrageously comfortable mattress sold directly to consumers. Its critically acclaimed sleep surface was developed in-house, has a sleek design, and is delivered in a small, "how did they do that?"-sized box. The company is one of the fastest-growing consumer brands of all time, and its product line has expanded to include sheets, pillows, a matching foundation, and a dog mattress. Casper was named one of Fast Company's 50 Most Innovative Companies in 2017, and its eponymous mattress was crowned one of TIME Magazine's Best Inventions.
