[Retail × Robot] ML Engineer/Data Scientist (10493)
職種Position R&D / Engineer /Technician (AI, Data)
会社概要Company profile This retail tech company develops and provides commerce platforms and consumer apps that allow more consumers to use online supermarkets and Q-Commerce, together with RCS (Robotics Convenience Store) and NFC (Nano Fulfillment Center) that utilize automation technology such as miniaturized automated warehouses and robots to meet the needs of Japanese online supermarkets and Q-Commerce operators regarding automation of fulfillment.

Founded under the vision of "transforming Retail with Digital and Automation to create the next CX,", the company has raised funds from well-known VCs such as UTEC-University of Tokyo Edge Capital Partners and DNX Ventures. increase. Currently (November 2021), the number of team members exceeds 20, and they are expanding the number of foreign nationals, especially HW and SW engineers. In addition, we have already introduced one RCS store so far, and we plan to introduce one RCS store and two NFC stores in 2022.

There are many industrial automation / robot solutions for BtoB, but until now, there have been solutions for creating services for BtoC, especially for retail, and for linking automation systems such as robots in real time with EC and apps. This is an area of ​​new challenges that most companies are not tackling. If you would like to take on the challenge together at a fast-growing company, please apply.

[Attractive points of company/work]
・ You can be involved in the development of new platforms that will be spread throughout the retail industry.
・ You can learn about development from members who were in charge of large-scale system development at a major domestic manufacturer.
・ Engineers can also participate from the planning stage and experience all the development from the upstream process to the downstream process.
