Hiring Background
LUX has an AI/machine learning development team, which has been working on AI-OCR development, but we have decided to strengthen our development team in order to further promote the use of AI in our services in the future.
The team is not only in charge of research and development, but also of developing AI systems for use in our services.
The team is still relatively new and the number of members is still small, but we are planning to expand the team to 7-8 members.

The team is still relatively new and has only a few members, but we are planning to expand to 7-8 members.
We are looking for a person who can add high value to our services by developing engines and models from scratch, incorporating cutting-edge AI technology.
We are looking for a person who can design, develop, and release functions with the aim of adding high value to our various services.

▼Team Member Biographies:
●Worked as a tech lead for several AI ventures, and experienced in many projects dealing with diverse data such as images, natural language, numerical data, and so on. Has a track record of not only creating models but also integrating them into systems and leading them to implementation. Joined our company in 2021 as the 1st AI engineer and has been working on improving customer value through AI implementation.

Environment
Languages used: Python, Go, Java, etc.
Frameworks and libraries: TensorFlow, Keras, Pytorch, etc.
Development environment: Mac, Linux, Windows, AWS, GCP
Code review: Pull Request based (using GitLab's MergeRequest)
Version control system: GitLab
Ticket management system: GitLab

Issues to be addressed
Mainly develop functions to support input and data creation in our services.
You will work on the development of AI systems, including not only the implementation of machine learning models and algorithms, but also their integration into actual systems (API implementation).
You will develop mainly in the areas of image recognition, natural language processing, and data analysis.

The main focus will be on image recognition, natural language processing, and data analysis.
1. As a relatively new development team, you will be a core member of the team in the future.
2. You will be able to work with specialists with a wealth of AI experience to promote the business and the organization.
3. You will be involved in the selection of the development environment, libraries, and algorithms, as you will be developing the machine learning engine and models from the ground up.
4. We have an environment where "everyone works together to create something good".
5. Most of the managers have engineering experience (4 out of 6), so it is an environment where engineers' opinions are easily understood.

Organizational Structure
Manager (50s, male, section manager) - 2 members
The overall number of engineers is about 250, divided into 7 departments and 25 development teams (sections) by product and role, each with 10 to 20 members.

Business Description
RakuRaku aims to help solve social issues where people and time are in short supply by using cloud and IT technologies to improve work efficiency. One of its representative services, the Rakuraku Series, is particularly strong in developing multiple services to support back-office operations (accounting, finance, human resources, sales administration, etc.).

▼ Features
We provide multiple SaaS services and are developing products that are widely used by enhancing each product. As an example, we focus on improving back-office operations for medium-sized companies, and aim to create products that are widely used without customizing them for specific customers. We will focus our efforts on expanding into areas where we can solve the pain points of many customers, and each product unit will have the strength in functionality and usability that makes it useful enough to be used in business operations.
Many of LUX executives are experienced engineers, and we consider product development as one of the important management centers.

Development Organization
While each service division employs a business unit system, the Development Division exists across services as a specialized technical organization of engineers. We believe that engineers can contribute more to the business if we create an organization that emphasizes the values they cherish and the culture they themselves create, and as a specialized technical organization that does not belong to a business division, we aim to create an environment where engineers can thrive and enjoy working.

Mission: To create overwhelmingly easy-to-use SaaS that leads customers to customer success.
Vision: To be Japan's leading SaaS development engineering group
Recognized by engineers throughout Japan as a leader in SaaS development
We work with confidence and pride that we are the No. 1 engineering group.
