Backend Software Engineer (C++)

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 systems.

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
