Cloud Platform Engineer (Go, Kubernetes)

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. A Quick Overview of What This Role Entails Mujin Portal is a cloud-based product that enables customers and Mujin engineers to manage and support Mujin robotic systems deployed across multiple sites. Portal runs in multiple regions across Japan and the US, on AWS and on our own Kubernetes clusters, and keeps a persistent connection to every Mujin Controller in the field. As the fleet grows, the platform underneath Portal matters as much as the features on top of it: how we deploy, how we scale across regions, how we observe and secure it, and how we keep it running when something breaks. As a Cloud Platform Engineer, you will own that platform. You will write Go alongside the rest of the team, but your focus is the infrastructure, deployment, reliability and security of Portal and the services around it. Responsibilities Design, build, and operate Portal's multi-region infrastructure on AWS and Kubernetes Own deployment and release tooling (Helm, GitOps with Argo CD, CI/CD pipelines) Build and improve observability: metrics, logs, traces, alerting, and on-call runbooks Keep the platform secure: networking, TLS and certificate lifecycle, secrets, identity, and access Operate stateful services such as PostgreSQL and object storage, including backups and recovery Write Go services and tooling where the platform needs code, and work with backend engineers on scalability and reliability Minimum Requirements Hands-on experience running production workloads on Kubernetes Hands-on experience with AWS or another major cloud platform, including networking and IAM Experience with infrastructure as code and GitOps or CI/CD tooling Ability to write and maintain production code in Go or another backend language Ability to independently own and debug systems end to end, with strong communication skills Preferred Requirements Experience operating multi-region or highly available systems Experience with OpenTelemetry, Prometheus, or similar observability stacks Experience operating PostgreSQL in production Background in security, certificate management, or zero-trust networking Experience with IoT, robotics, or systems connecting cloud software with physical devices Location 3-8-5 Tatsumi, Koto-Ku, Tokyo 135-0053, Japan Work Hours 8:45 - 17:45 (with a 60-minute break) Salary Based on experience and skills Salary revision twice a year Additional bonuses are available based on performance Holidays Every Saturday and Sunday Annual paid leaves Maternity leave and Childcare leave Flex Holiday (take public holidays on days of your choice) Other holidays as defined by the company Company Benefits Explore Mujin Perks & Welfare Benefits Flexible dress code policy Commuting allowance Japanese Social Security (Health Insurance, Pension, Labor Insurance) Monthly team dinner support Free buffet lunch every workday Free vending machines (offering drinks and snacks) High-end coffee machine Exclusive Employee Gym Access Japan Relocation Support Visa sponsorship Flight ticket support Shipping expenses coverage up to a specified limit Assistance for housing
