recruitment background
[Recruitment limit: 1 person]
No. 1 domestic market share and transaction value! You will be in charge of developing a job search application for freelancers, side jobs, and homes that has exceeded 4.2 million members.
Currently, there are only iOS/Android engineers in the app development team, so we are temporarily focusing on implementation that is completed within the app, but in the future, we would like to increase the functions that can be done on the app by linking APIs with web services. I'm here.
For that reason, we are looking for engineers who can develop smartphone application APIs with Ruby on Rails!
Company Info summary
We are developing our business centering on Japan's largest crowdsourcing service "our company".
A crowdsourcing service is a service that allows anyone to freely receive and place orders for work on the Internet. Don't be caught up in this time and place
We are involved in the creation of the next society through the expansion of new ways of working.
"I want to work as a freelancer without belonging to a company"
“I want to do another job while still working for the company.”

"I want to work in the city while living in the countryside"
“I want to work from home while caring for my family.”
“I want to work from home while raising my child.”
“I want to continue doing what I love after I retire.”
As individual lifestyles diversify, the way people want to work is also changing. We are crowdsourcing that is not bound by time and place
Through our services, we can achieve the above work styles. We deliver new ways of working and living to Japan and the world.
