Mujin is a global leader in industrial automation, redefining supply chain efficiency through MujinOS—our intelligent operating system for robotics. At our core is Machine Intelligence (MujinMI), a unique approach that leverages real-time digital twins and advanced perception, planning, and control algorithms to achieve fully autonomous operations.
Our flagship product, MujinController, empowers users with a highly configurable, no-code interface. By integrating cutting-edge motion planning and computer vision, it enables seamless automation for complex applications such as palletizing, picking, and truck unloading.
Headquartered in Japan with a growing presence in the US, China, and Europe, we invite you to join a dynamic environment where you can shape the future of automation.
The Senior Software Engineer (Robotics OS Validation & Simulation) is responsible for validating the Mujin OS across our entire robotics ecosystem used in live warehouses and factories.
In this role, you will design the automated testing architecture that ensures robotic systems behave correctly when deployed in real production environments. Rather than testing isolated components, you will validate how complete systems operate together—including robot arms, custom end-effectors, vision systems, conveyors, and other industrial equipment.
Most validation is performed through large-scale simulation environments that reproduce real customer deployments. The test infrastructure runs continuously in automated environments to ensure Mujin OS continues to operate safely and reliably in production as the system evolves.
This role is ideal for engineers who enjoy working on complex, real-world systems where software, hardware, networking, and physics intersect.

Mujin offers the complete robotic solution. Our core technology is the Mujin Controller, which manages any robotic application by controlling the movement of any robot arm via artificial intelligence and autonomous motion planning. This allows our end users to define the application and choose the best robot arm for the job.
The Mujin Controller makes every robot more capable, efficient, and reliable. Our motion planning algorithm is one-of-a-kind and allows robots to perform practically any application with the most efficient path.
To create the full solution, we combine state-of-the-art vision systems with highly versatile end of arm tooling to manage the variability of any application. We have standard products for standard applications and custom solutions to solve any application.
