Job Description

ZigZag is looking for a Ruby on Rails Engineers to join our team!

Our client is looking for a Ruby on Rails Engineers responsible for maintaining their backend services serving users on mobile(iOS/Android) and web (React) applications.

Your primary focus will be development of server-side logic to fulfill new feature requirements and maintaining existing services, ensuring high performance and responsiveness to request from the front-end client’s partners/customers.

Essentially, they need someone with knack of writing clean, readable Ruby code.

About the Client

Our client founded in 2014 by Australian TV host who fell in love with the power of social media after helping build the most engaged Facebook brand page in the country. Our client discovered that for the price of one sponsored post from a celebrity, fashion blogger or YouTuber, you could enlist 50 micro-influencers.

For the same price you’d reach more people, total engagement would be far higher and instead of having one piece of content to repurpose, you’d have 50!

But, since no one has time to manage 50 influencers manually, our client designed an app. It’s goal? You guessed it: to unlock the world’s creativity.
