Hatch is a sleep wellness company serving 5+ million users with IoT devices and mobile apps designed to help people build healthier sleep habits. The company is headquartered in Menlo Park, California and backed by world-class investors.
As a Backend Engineer II, you will build, ship, and operate the backend infrastructure powering Hatch's mobile apps and IoT devices. You'll work with Java and Python REST APIs, AWS IoT, Lambda, and DevOps practices that keep millions of devices running reliably in customer homes. The role reports to the Director of Backend & DevOps and sits within a small, high-ownership engineering team that uses AI-assisted development as a core practice.
In your first 90 days, you'll learn the backend architecture through team walkthroughs and hands-on exploration, ship well-scoped features in the Spring Boot + Hibernate stack, and join architecture discussions. By six months, you'll independently deliver medium-sized features end-to-end, own a component within core areas (IoT device communication, auth flows, device scheduling, or mobile app backend support), troubleshoot production issues, and improve monitoring and alerting. Within your first year, you'll own a backend area, lead large projects with senior guidance, improve reliability and developer experience, and help onboard new teammates.
You'll collaborate closely with Mobile, Embedded, and Product teams to build features from cloud APIs to device firmware. The environment emphasizes rapid learning, self-direction, business understanding, and delivering customer value. The company practices a customer-obsessed culture with tools for product analytics, dedicated exploration time, and continuous learning through cross-functional workshops and customer shadowing.
Hatch is remote-friendly and open to candidates across the US and Canada, though availability during PST/PDT hours is required.
