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
