Senior Fullstack Software Engineer (Node.js)

About Raydiant: more than half of all new televisions are being sold to businesses. But to use them, businesses either need to improvise (think Chromecast and an old Android, or a DVD player playing on loop) or spend tens of thousands of dollars on racks of hardware and bespoke software. Yes, it’s really that bad.

But it’s easy with Raydiant. At Raydiant, our hardware and cloud software unlocks the power of these displays by making it easy to display media (like video or music), information (like menus or flyers), and interactive content (like teleconferencing or whiteboards) at a price that any business can afford.

We’re growing like crazy and we need your help. Founded in April 2017, Raydiant enjoys support and financial backing from top strategic and technology investors, including Bloomberg, Inc., Transmedia Capital, 8VC, Atomic VC, and Ron Conway. Our customers include Wahlburgers, Chick-fil-A, Harvard University, the Dallas Mavericks, CiCi’s Pizza, and Westin. Our team consists of seasoned engineers and executives with deep backgrounds in relevant industries. We are looking for like-minded individuals that want to help us scale the business, continue to create and provide great experiences to our customers and have fun along the way.
