Senior Software Engineer

Senior Software Engineer, Home Automation Experience Team

Our Home Automation Experience (HAX) team owns the full home automation domain at Alarm.com including devices, device groups, rules, schedules, scenes, and automation-related notifications, for both customers and dealers, across web, mobile, and the backend services that make it all work. Alarm.com is a smart-home-as-a-service platform — our products reach end customers through a network of professional security and smart-home dealers who install, configure, and support our systems, which means HAX builds for two distinct audiences with very different needs. If 'intuitive, accessible, reliable home automation' is the kind of problem you want to spend the next several years on, this is a good place to do it.

As a Senior Software Engineer on HAX, you'll lead design and delivery of high-impact features end to end, from partnering with Product Management and Quality Engineering, mentoring engineers around you, to shaping technical direction in design reviews and architectural decisions. You'll move across the stack as the work demands: frontend, backend, data, infrastructure.

Alarm.com is one of the few places you can build consumer products that ship at a consumer scale across this kind of technology surface (wireless, software, hardware/device) without changing companies. Engineers here go deep in their area and stay curious about everything else.
