Sr. Ruby on Rails Engineer - Help Retailers Compete with Amazon!

San Francisco, CA | Engineering

Job Description

About Us:

500friends helps retailers increase their customer lifetime value. This is really important today as retailers are getting their butts kicked by Amazon (on-line) and Walmart (off-line). 

We're backed by $12M in financing from Crosslink, Intel, and YCombinator and are trusted by over 40 of the Internet Retailer 1,000. Our management team also has a proven track record of building great companies and taking them to attractive exits. Our technology stack includes Ruby, Rails 3, MySQL, EC2, Amazon Redshift, and more.  We have scaled the system 25x in 9 months, and plan to double that by December!


As a member of our small but seriously talented engineering team, you will play a key role in both shaping and building our technologies. Your scope will be broad, ranging from user-facing features to server-side components and libraries. We are looking for a generalist who enjoys learning and working with different technologies. And of course you will be expected to commit code on your first day. 

Yes, we realize that smart hackers are in demand. So what makes 500friends special?
