Job Description

【What is "Loogia"?】
"Loogia" is a dispatching system that achieves overwhelming efficiency in the last mile*. It creates delivery plans – "which vehicle, to which destination, in what order, and via what route" – in minutes, considering complex conditions and on-site constraints, to provide efficient routes.
*The last mile refers to the final leg of the delivery process until the consumer receives the product.

【Job Responsibilities】
You will be active in frontend/backend development for one of Loogia's services below. We will consider assigning you to a team based on your experience and preferences during the selection process.

▼ Web application development for the "Plan Creation" domain:
・ Maximize customer UX through enhancing features related to creating and modifying delivery plans (e.g., handling cancellations/time changes, supporting plan creation before order deadlines).
・ Tackle diverse requirements such as plan creation features that consider more complex delivery costs and individual driver proficiency, as well as support for trade-in operations.

▼ Web application development for the "Plan Execution & Fleet Management" domain:
・ Contribute to real-time delivery status tracking, management task support, and delivery quality improvement through driver apps and fleet management systems.
・ Drive feature development that strongly supports on-site delivery operations, such as inspection functions during loading/delivery and voice navigation for smartphones. We aim to create an app that allows anyone to perform delivery tasks with high quality and productivity.

▼ Web application development for the Connect "Data Integration & Pre-processing" domain:
・ This involves developing mechanisms responsible for data integration with customers' existing systems (e.g., order management, warehouse management). It automates cumbersome data preparation and achieves overall operational efficiency through data transformation, merging, and providing GUI for human editing.
・ We aim to expand from enterprise customer implementation to the Mid Market in the future, considering new mechanisms like no-code integration.
