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. We are looking for a Backend Engineer to design, build, and own the core backend systems that power our industrial robotics platforms. In this role, you will take end-to-end ownership of backend components supporting robot controllers, working close to hardware, sensors, and operating systems to deliver reliable, high-performance systems in real-world production environments. You will design and operate low-latency services, data-intensive pipelines, and robust communication paths that directly influence system behavior on the factory floor. This role requires strong systems thinking, a focus on performance and reliability, and the ability to drive improvements independently across complex, evolving

Responsibilities

  • ● Design and own backend systems for industrial robotics platforms
  • ● Take end-to-end ownership of backend components supporting industrial robot controllers
  • ● Design, implement, and maintain reliable backend services and APIs with strong focus on performance and stability
  • ● Work on low-latency communication paths, including high-performance HTTP services and inter-process communication (e.g., ZeroMQ)
  • ● Integrate and support sensor-driven data flows
  • ● Develop and maintain backend components that interface with sensors such as 3D cameras and other industrial devices
  • ● Work with sensor SDKs, drivers, and APIs to ensure predictable data ingestion and behavior
  • ● Debug issues that span application logic, OS behavior, and device interaction
  • ● Build and operate data-intensive backend pipelines
  • ● Own and continuously improve high-performance data pipelines that influence system-wide behavior
  • ● Design database usage and data access patterns with strong awareness of scale and efficiency
  • ● Contribute to defining, validating, and improving system metrics and KPIs
  • ● Drive system reliability and operational excellence
  • ● Diagnose and resolve complex production issues across multiple system layers
  • ● Contribute to controller provisioning, reset, and upgrade workflows with a focus on stability and predictability
  • ● Improve observability, diagnostics, and operational tooling to reduce long-term operational risk
  • ● Solve complex, real-world engineering problems
  • ● Operate effectively in complex systems with evolving requirements and constraints
  • ● Make architectural and design decisions balancing performance, reliability, and maintainability
  • ● Drive improvements independently, from problem identification through implementation and rollout
