「世界中の家庭や施設に生活支援ヒューマノイドを普及させる」

Enactic は、支援が必要な人の自立性と生活の質(QOL)を高めるヒューマノイドロボットを開発・提供することを使命とするディープテック企業です。

高齢化による深刻な労働力不足という世界的課題に直面する中で、私たちはその解決に貢献することを目指しています。

Responsibilities

As our Controls and Reinforcement Learning Research Scientist, will be responsible for developing high-performance, reliable control systems for robots, including designing, implementing, and tuning motion-control algorithms that enable real robots to acquire advanced motion skills.

Leveraging principles from control theory, reinforcement learning, and multimodal AI models, you will build controllers that balance robustness, adaptability, and real-world feasibility.

You will iteratively validate and refine these algorithms in both simulation environments and on real hardware, continuously elevating system performance.

You will also collaborate closely with hardware, firmware, and AI model development teams to create practical, end-to-end solutions that span robot design, control architectures, learned policies, and deployment on physical robots.
