Senior Data Scientist

**Position:** Applied Data Scientist \& ML Engineer

(Job title is flexible/negotiable depending on background)

**Locations:** Tokyo, Osaka, or Nagoya (Hybrid)

**Annual Salary:** ¥10M -- ¥19M (commensurate with skills and experience)

**Japanese:** Fluent/Native level

**Why This Role Matters**

Most AI projects get stuck in lab demos and never make it to daily operations. We focus on fixing that disconnect.

Heavy industries---such as automotive, energy, and precision equipment---still run on millions of complex technical drawings, vendor quotes, and paper specs. We build intelligent software platforms that convert these messy real-world files into actionable insights, helping engineering teams speed up delivery, cut supply costs, and improve build quality.

We need hands-on technical talent to take full ownership of bringing AI solutions directly into live enterprise production.

**What You Will Do**

* **Map \& Structure Real Data:** Study how client teams work day-to-day and turn raw operational records into clean, well-architected pipelines.
* **Deploy LLMs into Production:** Build and fine-tune machine learning and language model workflows, verifying accuracy with hard benchmarks rather than guesswork.
* **Bridge Systems:** Connect custom algorithms to enterprise cloud databases, monitoring system health and model drift after release.
* **Scale Solutions:** Spot recurring technical problems across client sites and feed reusable components back into our core software platform.

**What We Expect**

* **5 years** in data engineering, data science, or machine learning roles.
* **3 years** building and running data pipelines in production environments (hands-on code reviews and system architecture experience).
* **1 years** using modern LLM APIs to build features deployed for actual business users, backed by concrete performance and precision metrics.
* **2 years** working directly with product or business stakeholders to define technical requirements from scratch.
