Do you have an unyielding passion for robotics, mechanical systems, and cutting-edge software? Do you find joy in solving complex physical problems and deploying real robots to perform tasks previously deemed impossible?

If so, industrial robotics offers one of the most intellectually rewarding fields in modern engineering. At Mujin, we empower engineers to harness their creativity, bridge the gap between academic theory and physical reality, and build production-grade autonomous systems.

:::note[The Reality of Industrial Physics]
You don't need to be an encyclopedic expert in every discipline. Robotics is an inherently cross-functional domain uniting software, kinematics, mechanics, and electronics. What matters most is a solid grasp of fundamentals—physics, linear algebra, algorithms—and a **commonsense, safety-first mindset**. When dealing with two-ton industrial robots, momentum, inertia, and motor heating cannot be abstracted away.

### The Hardware Playground: 60+ Robots Under One Roof

Precision in industrial robotics is governed by the laws of physics. As an arm's reach and payload increase, structural deflection, joint compliance, and inertia amplify millimeter deviations into critical positioning errors. Solving these challenges requires testing on real physical hardware.

From our humble beginnings in a 41 m² garage in Koishikawa, Mujin's Tokyo headquarters has grown into the **14,500 m² Tatsumi Robot Center**—one of the largest private robotics facilities in Asia.

- **Diverse Robot Fleet:** Over **60+ distinct robot models** are actively operational across our engineering and testing bays. Because MujinController is hardware-agnostic, our floors feature arms from FANUC, Yaskawa, Kawasaki, Mitsubishi Electric, KUKA, and ABB.
- **Massive Heavyweight Payloads:** We deploy heavy industrial arms handling up to 190 kg, equipped with custom-engineered end-effectors and suction frames that alone can weigh over 70 kg.
- **Integrated Warehouse Ecosystems:** Beyond robot arms, the center features high-speed pallet conveyors, autonomous mobile robots (AGVs/AMRs), safety interlocks, and sensor rigs mimicking client distribution hubs.

### Software & Digital Twins: Simulating the Physical World

While the mechanical hardware provides raw power, the software determines whether the system succeeds in unstructured environments. 

Our flagship platform, **MujinController**, is powered by **MujinMI (Machine Intelligence)**, coordinating up to ten degrees of freedom with analytical inverse kinematics and real-time collision checking.

**Large-Scale Simulation Clusters**

Testing every corner case on physical hardware would be impractically slow and risk collisions. We maintain high-density compute clusters that run thousands of automated physics simulations nightly—modeling motor temperatures, friction, and joint limits.

**Modern Engineering Toolchain**

Our core codebase utilizes C++ for hard real-time execution, Python for data manipulation and tooling, with Go and C# across distributed services and cloud telemetry.

### Empowering Engineers: Our Culture & Community

Solving open problems in robotics is notoriously difficult because real-world physics doesn't offer trivial closed-form answers. Real-time path planning in high-dimensional configuration spaces requires balancing trajectory smoothness, cycle time, and obstacle clearances within fractions of a second.

**Fast-Track Growth**

Career progression is driven by capability and passion, not tenure. Several team leads joined Mujin as university interns and rose to leadership roles within five years.

**Flat, Direct Communication**

Our open office layout eliminates corporate bureaucracy. Developers can walk directly to the CEO, CTO, or head of hardware to discuss ideas or resolve blockers.

**Production-Grade Impact**

The algorithms you write and debug today don't stay in academic papers—they run 24/7 in state-of-the-art warehouses across Japan, the US, and Europe.

:::tip[Bridging the Academic Gap]
For recent graduates, working at Mujin offers the fastest route to bridging the gap between university theory and real-world deployment. For experienced industry professionals, it is a chance to work with the most versatile robotics hardware fleet in the world alongside top international researchers.
