▼Job Description
▍Mission
￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣
With the mission to "create infrastructure that makes the entire city like a 'station front'," LUUP aims to be new infrastructure for short-to-medium distance travel that fills and complements the gaps in existing transportation infrastructure. If the railway network is the main artery, LUUP aims for a future where the entire city becomes as convenient as a "station front" by creating a fine-grained network of mobility like capillaries, thereby increasing the value of the city as a whole.
Furthermore, by introducing universal vehicles in the future, we will continue to build infrastructure to realize a future where everyone, including the elderly, can travel comfortably.
▍Role and Overview of the Operations Development Team
￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣
Our role is to support the core of physical operations with the power of technology and accelerate its evolution. LUUP's business is not completed by software alone. The foundation is the complex operations in the "physical world" where 15,000 ports nationwide, over 40,000 vehicles, daily on-site staff, and safe customer travel all interact.
Engineers will tackle a wide range of technical challenges based on a modern cloud-native environment using Google Cloud and AWS. This includes designing and operating event-driven architectures that handle large-scale real-time data from tens of thousands of IoT devices, building scalable infrastructure (IaC) to support rapidly expanding traffic, promoting SRE practices to ensure reliability as social infrastructure, and driving the core of the business from the engineering domain through UI/UX development connecting data and field operations using TypeScript and Go, as well as technical challenges that transcend positional boundaries.
You will be challenged to build large-scale systems that can be considered social infrastructure, directly linked to business profitability and service quality, going beyond simple tool development.
Details and content will change according to the roadmap and situation, but please refer to the following as a reference for the specific tasks the team will be responsible for.
▍Specific Job Responsibilities
￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣
(1) Optimization of vehicle placement and battery replacement through data prediction
You will be responsible for developing systems that maximize vehicle utilization for on-site operations.
- Building and improving demand forecasting models:
- Developing and improving applications that build models to predict future demand and supply based on past ride data, weather, and human flow data, and systemizing/optimizing the underlying operational processes.
- Implementing mathematical optimization algorithms:
- Based on these predictions, collaborate and coordinate with the data science team to apply and develop complex algorithms such as "which ports to move vehicles from and how many" and "in what order to replace batteries" using TypeScript and Go, for demand forecasting (machine learning) and delivery planning problems (mathematical optimization).
(2) Repair lifecycle management and supply chain optimization
To ensure safe vehicles are continuously provided to customers, we manage and optimize the entire process from failure judgment and repair to parts supply.
- Building physical operation integration systems:
- Building systems for collecting broken-down vehicles, tracking their status at repair bases, and logging parts used, based on real-time data and hardware integration (BLE/MQTT) from tens of thousands of vehicle IoT devices.
- Advanced inventory management:
- Collaborating with the data science team to utilize accumulated failure and repair data to advance AI-based prediction of future repair parts demand and inventory optimization.
(3) Development of data-driven sales support system
We are developing data-based sales support tools to solve the challenges faced by port sales representatives in selecting and determining the content of proposals.
- Data integration and visualization:
- Integrating data from Salesforce, demographic data, commercial area data, existing port usage status, etc.
- Supporting sales and field decision-making:
- Developing UI/UX that allows sales and field representatives to fully utilize information for each candidate location, aiming for faster port installation and more convenient LUUP usage.
*Scope of changes to job responsibilities: Duties assigned by the company.
