Join to apply for the Mechanical Prototype Engineer role at Hatch

There’s nothing like a great night’s sleep—the cozy, wrapped-up-in-a-heavy-blanket kind of sleep. The fire-crackling, curtains-drawn, DO NOT DISTURB kind of sleep. You know, the good stuff.

But here’s the thing: while 85% of people agree sleep is the key to their well-being, more than half are unsatisfied with their own. Whether it’s stress, interruptions, work, or little ones waking in the night, so many people need help getting truly restorative rest.

That’s where we come in. At Hatch, we’re on a mission to help people build better sleep habits—so they can feel more focused, energized, and present in their lives. We’ve designed best-in-class smart sleep devices, paired with science-backed sleep content, to help people unwind nightly, sleep deeply, and wake gently. More than 5 million sleepers of all ages have made space for rest with Hatch, with our baby products in 1 in 3 nurseries and our adult product, Restore, taking over nightstands (and Tik Tok) worldwide.
