Senior Embedded Systems Engineer

Join the Rest Revolution The world is wired and tired. It's plagued by screens, notifications, and the sense that you should always be doing ... something. But hey, you're reading this job application right now, so you probably know exactly what we're talking about. So here's a bit of good news amidst all the noise: Hatch is a sleep wellness company that's betting on rest in a culture obsessed with optimization. While most technology is designed to keep you engaged, our devices use the science of habit formation to help people unplug, unwind, and recharge. Through genuinely enjoyable routines, habit building, and gentle guidance (no sleep scores or wearables here), we help people build healthier sleep habits and feel the difference in everyday life. More than a decade ago, we started with a mission to help parents navigate the complexities of newborn sleep. Today, we're helping more than 5 million people (and counting) take care of themselves and the people they love through the power of rest. We’re open to candidates across the U.S. and Canada.
