[Background of recruitment]
Recruitment frame: 4 people
Now that the digital transformation is accelerating, the demand for easy and seamless ordering and payment using iPad and iPhone is increasing in the service industry business such as food and drink and retail.
In order to promote the construction of a platform for the service industry by diversifying and deepening services, we will actively hire engineers who will enhance new development capabilities and operational stability together.

[Career path]
Since we are developing as a team, you can decide for yourself how to develop your skills, such as challenging adjacent areas centered on your area of expertise, or digging into your area of expertise to become a specialist.
Since we are developing our own products, we can continue to be involved in delivering valuable products to our customers by continuing to improve while operating as well as developing.
Company Info Development and provision of SaaS type POS system utilizing iPad
Our mission is to help people in all service industries, not just as a sales management system, but to sublimate the data infrastructure of the service industry.
It is not a service for people who are familiar with IT, but an environment where everyone can maximize their abilities is created, and a detonation that creates a lot of value that has the potential to help resolve global disparities. I think it can be a drug.
Instead of a large POS cash register terminal, we offer a cash register by combining an iPad and a web application.
We will improve the operation of the store by offering an intermediate choice between the inexpensive but primitive "mechanical cash register" and the high-performance and expensive "POS cash register".

◆ iPad POS cash register
◆ Ordering system
◆ Inventory management system
◆ QR order
◆ Salesforce
