Role Description You'll own the architecture, delivery, and reliability of the backend behind Hatch's mobile apps and IoT devices. That means Java and Python REST APIs, AWS IoT, Lambda, and the monitoring, alerting, and DevOps practices that keep millions of devices humming in real homes. You’re a great fit if you thrive in environments of rapid learning and delivery. You’re self-motivated and have demonstrated strong ownership and self-direction. You strive to understand the business of what we are trying to accomplish and push engineering solutions to provide customer value. As a small team where AI-assisted development is core to how we work, we expect this senior role to ramp up quickly, use AI fluently in their day-to-day, and deliver broadly across our backend systems. Working across Mobile, Embedded, and Product, you'll lead system design, set technical direction, and mentor engineers. It's a uniquely end-to-end role—cloud APIs on one side, physical devices on the other.
