Job Description

About Us:

Nixle's web-based communications products are "Building Safer Communities" all across America. With over 6,800 public safety agencies currently using Nixle to notify the public via text, email, and voice messages, we are literally saving lives and catching bad guys. Sure that sounds a little cheesy, but what we do makes a difference in people's lives and that makes getting up and going to work enjoyable, each and every day.

Founded in 2007, and headquartered in San Francisco, Nixle provides a cloud based mass notification service that enables effective communication and collaboration between more than 6,800 public safety agencies, their school districts, and the communities they serve. Nixle’s secure platform of text message, email, smart phone app, and voice notifications allow public safety agencies to share relevant information quickly and effectively. Additionally, Nixle helps mobilize those communities to take an active role in public safety through anonymous, real time, two-way notification via text messages.
