About the company
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.
About the role
Our team develops MujinOS’s fundamental algorithmic layer, blending control algorithms, real-time motion planning, and advanced packing algorithms. This layer powers downstream applications including palletizing, piece-picking, and depalletizing, allowing users to build solutions efficiently on our platform.
We work in a fast-paced, agile environment where we collaborate closely, review ideas openly, and iterate quickly. Continuous learning and technical curiosity are strongly encouraged.
As part of the Robotics System Team, you will design, develop, and deploy advanced algorithms that power Mujin’s real-time industrial robotic systems.
Team Structure & Focus Areas
Our team consists of three core algorithmic tracks. You may specialize in one while collaborating across all:
Control Algorithms
Real-time trajectory control, robot dynamics, multibody modeling, and precision execution.
Motion Planning
Collision checking, sampling-based planning, optimization-based planning, high-speed bin-picking motions.
Packing Algorithms
Geometric reasoning, packing optimization, item fitting strategies, and fast combinatorial search.
Responsibilities
•
Tackle scientific and technical challenges in motion planning, control, packing, and system design for industrial robots (robot arms and other peraherals).
•
Design, develop, and test algorithms for robotic manipulation tasks such as picking, packing, and material handling.
•
Build highly concurrent, performance-critical software systems.
•
Implement and optimize real-time communication modules with robot controllers and peripheral devices using C/C++.
•
Team up with our project management and integration teams to support PoCs and ensure that our technologies work smoothly in real customer setups.
Minimum Requirements
•
Academic background in Computer Science, Robotics, Mechanical Engineering, Electrical Engineering, or related fields
•
5+ years of academic or industry experience in robotics and software engineering
•
Strong proficiency in C++ and Python
•
Solid understanding of linear algebra, 3D geometry, and their applications in robotics
•
Experience working in Linux environments
•
High motivation to solve real-world robotics problems
•
Business level English skills or Japanese skills
Preferred Qualifications
•
Experience with concurrent or hierarchical robotic software stacks (e.g., ROS, OpenRAVE, custom frameworks)
•
Hands-on experience with multi-joint robot hardware
•
Advanced Linux skills
•
Mathematical foundations in areas such as multibody dynamics, collision checking, graph/search algorithms, or optimization
Why Mujin
•
Your work doesn’t stay in simulation—your algorithms become production-grade, real-world applications such as palletizing, picking, and depalletizing that run on factory floors globally.
•
You will work on real industrial robotics problems, and your algorithms will be deployed rapidly to solve previously impossible automation challenges.
•
Our team is made up of experienced robotics specialists from top global programs (e.g., NTU, CMU, Stanford). You’ll work alongside supportive teammates and mentors who share knowledge openly and help each other grow.
•
We develop the core of the Mujin platform in-house, unifying planning, perception, simulation, and control so we can shape the entire system with complete autonomy.
