Opportunities from Mujininc (lever)

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

BSc degree or higher in Computer Science, Computer Engineering, or related fields, or equivalent academic or work experience

Excellent experience and high proficiency in C++ and Python

Advanced Linux user, excellent experience in Linux software development

Expert in Linux internals, networking stack, network protocols, routing, async I/O, Docker and its internal workings

Experience in full-stack development

Technical communication skills in English

Expert in real-time OS, Linux kernel module development, EtherCAT

Experience in robotic software development

We are looking for individuals who are ready to take ownership of challenging problems, work proactively and independently, and collaborate closely with team members across the organization.

You will work hands-on across the industrial robot controller stack, rather than being limited to a single component, and will tackle problems that may be new or unfamiliar, often requiring deep investigation and learning.

Since this work has broad impact across the engineering organization, Backend System Engineers play a key role and collaborate closely with many teams.

Coding Assessment: Initial technical evaluation.

HR Interview: Discussion with Human Resources.

Hiring Manager Interview: One or two rounds with the hiring manager.

Take-Home Assignment & Feedback Interview (If Applicable): A task to complete on your own, followed by a feedback session.
