Ruby on Rails Developer (Mid-Sr level)

Telmate is an industry leader in managed telecommunications for governments, where we innovate disruptive technology from our offices in California and Oregon. Our systems carry tens of millions of minutes of voice every month. We have customers in 40 U.S. states and two Canadian provinces and are adding more all the time.

This is not your normal web application gig – we’re not making another Twitter clone for your grandma. We dabble in all aspects of computing, from trying to scale Ruby on Rails, to building our own hardware, to smashing it with hammers — seriously, with actual hammers. This is a key role and you’ll be right in the thick of it from day one.
