Company overview

Our mission at Eridan is to connect the planet to empower a sustainable, shared future. We are achieving that goal with an entirely new way to generate RF signals using a direct polar transmitter built in Gallium Nitride. Our novel transmitter architecture decreases the cost and power required to roll out 5G by 10x. This enables affordable broadband connectivity everywhere by lowering the barriers to install and maintain networks globally. We are a rapidly-growing startup with a casual and energetic environment. We use collaboration and communication to enable outsized results. Our headquarters in Sunnyvale, CA has big windows (even in the lab!), is walking distance to downtown and the Caltrain, and fits the entire team in the cafeteria for our frequent company parties. We offer pre-IPO equity, generous PTO, 401K with automatic matching, and health, dental, and vision insurance. Learn more about Eridan and our mission here. eridan.io | LinkedIn | Twitter
