-------------【About the company】-------------

The company will create a society in which all people involved in manufacturing can maximize their inherent power.

To achieve this goal, they will create a "new mechanism" that will change the common sense of industry.

Busy with estimating and administrative tasks, lacking sales skills, and lacking information and networks.

By untying these shackles, the potential of each company can be unleashed.

From small factories in town, to large manufacturers with a long history, to start-ups in their early years, all manufacturing companies will shine by leveraging their strengths to create new value.

They will continue to take on the challenge to open up such a future.

◆Flat organization

Regardless of your position, team, previous experience, gender, age, etc., you can express your opinions and immediately incorporate what is good.

◆Excellent members

The team is made up of members who have been active in leading companies. You will have an environment where there is a growth and stimulation every day.

◆Engineer Driven

Since they are operating in a field where there are no precedents yet in the world, technical skills are extremely important, and engineers play a leading role.

-------------【 Job Description】-------------

The company develops and operates a "Manufacturing AI Data Platform."

This platform transforms the vast amount of dormant knowledge and experience within the manufacturing industry into actionable assets that anyone can leverage. Since its launch in 2022, it has already been adopted by a wide range of clients—from major domestic manufacturers to processing companies—and is growing at a phenomenal pace that significantly outstrips the T2D3 growth trajectory.

Currently, the company is accelerating its global expansion, having already established a presence in the United States, Thailand, and Vietnam.

【Responsibilities】

The company's product consists of a core data platform and specialized business applications that leverage that data, providing opportunities to apply machine learning and data science to both areas. The primary objective of this role is to drive data utilization through advanced analytics, directly translating into enhanced product value.

You will be expected to leverage the company's data by applying robust verification techniques to explore new technologies, utilizing advanced modeling skills to deliver tangible product value, and contributing to stable, team-based system development.

Below are examples of potential responsibilities. Actual duties are not limited to this list and will be finalized upon joining the company, taking into account your technical background, expertise, and experience.

【Example Responsibilities】

・ Prototyping and PoC for New Products

You will rapidly execute the following processes to reduce technical and use-case uncertainty, directly translating concepts into product implementation:

Problem Discovery & Solution Proposal: Aim to resolve complex bottlenecks within manufacturing workflows by working in lockstep with designers, product managers, and domain experts. Through user interviews and deep-dive discussions, you will isolate core issues and plan technical approaches rooted in cutting-edge tech, such as LLMs and mathematical optimization.

Prototyping & Proof of Concept (PoC): Execute PoCs based on the planned initiatives. You will build rapid prototypes using lightweight UI tools like Streamlit, gather direct feedback from on-site users, and run fast feedback loops to validate effectiveness and make improvements. Concurrently, you will leverage any and all analytical resources necessary to solve technical roadblocks that arise during this phase.

The Vision

Over the next few years, the company plans to launch a wide array of new applications globally on top of this platform.

Each of these applications holds enough market potential to operate as a standalone startup. By seamlessly integrating them, the company aims to build a comprehensive ecosystem that redefines the manufacturing industry.

Realizing this grand vision requires overwhelming drive and leadership. The company is looking for team members in this challenge: taking software born in Japan and establishing it as the global standard for a massive international market.

【Key Experiences & Growth Opportunities】

・Driving Major Industrial Impact: You can experience the profound fulfillment of utilizing AI to directly solve massive bottlenecks within the manufacturing sector. By working closely with client companies facing critical operational challenges, engineers will formulate hypotheses, execute rigorous verification loops, and refine product features to deliver tangible solutions.

・Full-Stack Skill Acceleration: This position involves the end-to-end lifecycle of product development—from initial ideation and PoC prototyping to product implementation and long-term operations. This holistic exposure allows individuals to experience the entire product development process and sharpen their expertise across a broad technical spectrum, encompassing machine learning, optimization algorithms, UX design, frontend/backend engineering, MLOps, and LLMOps.

・Shaping Greenfield Product Launches: Application development on the company's Manufacturing AI Data Platform is still in its infancy. Joining as a founding member of a small, highly elite team gives individuals a direct hand in shaping the engineering organization and technical strategy, paving a clear career path toward future Tech Lead or Engineering Manager roles.
