# Platform Engineer at Mujin

- **Company:** Mujin
- **Location:** Tokyo, Japan
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2026-10-01
- **Last confirmed live:** 2026-10-14
- **Apply:** https://jobs.lever.co/mujininc/b900ad83-0bf8-408a-98eb-3d4ad8850e5e

## Job description

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.

## About the Team

The Engineering Enablement team builds the internal platforms, services, and tools that help Mujin engineers develop, test, release, and support software effectively. The team works across a broad range of areas, including CI/CD, build systems, testing infrastructure, release workflows, observability, and internal developer tooling. Team members bring different areas of expertise while contributing across the broader platform. You will work closely with experienced engineers in the team, initially contributing to areas such as CI/CD, release and support workflows, and internal developer tooling, with opportunities to expand into other Platform Engineering areas over time.

## About the Position

This role is intended for a software engineer who already has hands-on experience building and maintaining software, services, or developer tooling and wants to develop deeper expertise in Platform Engineering and Developer Experience. You will contribute to both existing tools and workflows and new development, including internal services, automation, CI/CD pipelines, release and support workflows, and developer-facing tools. Rather than focusing primarily on infrastructure operations, you will build software that improves how engineering teams work across Mujin. You do not need to come from one specific Platform Engineering background. We value broad software engineering experience and practical experience with developer tooling, automation, CI/CD, or related areas.

## Responsibilities

- Build software that engineers rely on: Develop and improve internal tools and services that support engineers across Mujin.
- Shape the developer experience: Work across CI/CD, build tooling, release workflows, documentation tooling, log collection, and internal support workflows.
- Work on a broad range of engineering problems: Contribute to both new tools and existing systems, with opportunities to work across Rust, Go, and Python.
- Build for modern development environments: Develop and improve tooling and services used in containerized environments, including Docker and Kubernetes.

## Minimum Requirements

- 3+ years of professional software engineering experience
- Hands-on experience designing and building software services, command-line tools, developer tools, or internal engineering systems
- Professional programming experience with at least one general-purpose language such as Rust, Go, Python, C++, or a comparable language
- Experience contributing to software across multiple technical areas or layers of a system
- Understanding of software development workflows, including areas such as CI/CD, build systems, testing, deployment, or release processes
- Ability to collaborate with engineers and understand the needs of internal users

## Preferred Requirements

- Experience working in a Platform Engineering, Developer Experience, Engineering Enablement, or similar team

- Experience building tools or services used by a large engineering organization

- Experience with Rust, Go, or Python

Interview Process

- Resume Screening
- Take-home coding test
- HR interview
- Technical interview
- Culture/Team fit interview

Attractives

- Impact engineering at scale: Build tools and services used by engineering teams across Mujin.
- Broaden your engineering experience: Work across a wide range of areas, from CI/CD and build tooling to release and support workflows.
- Build, not just operate: This is a software engineering role where you will develop tools and services, rather than focusing primarily on infrastructure operations.

## About Mujin

## Company Overview
- **One-liner**: Mujin develops intelligent robotics automation platforms that use a "teachless" no-code approach to make robots capable, easy to deploy, and simple to operate in logistics, manufacturing, and beyond.
- **Entity Type**: Private (Series C)
- **Headquarters**: Tokyo, Japan
- **Founded**: 2011
- **Founders**: Ross Diankov (CEO), Issei Takino

## Core Business
- Primary industry: Industrial robotics and automation
- Target customers: Warehouses, distribution centers, manufacturers (primarily Enterprise and B2B); also serves robotics integrators
- Mission statement: To solve the shortage of manual labor by deploying intelligent robotics automation that raises productivity around the world

## Products & Services
- **MujinOS**: A no-code, teachless platform for robot control and deployment. Integrates perception, planning, and control algorithms with a real-time digital twin. Compatible with top robot and tooling brands.
- **Palletizing**: Automated case stacking with high-speed, stable pallet builds for any SKU mix.
- **Depalletizing**: Perception-driven robots that unload pallets and handle complex mixed-SKU challenges.
- **Mixed-Case Fulfillment**: Robotic case picking and pallet building for store-ready orders.
- **Bin Picking**: Robots pick loose items from bins using advanced 3D vision.
- **Piece Picking**: Each-pick automation for e-commerce and distribution.
- **TruckBot**: Container and trailer unloading robot (debuted at ProMat 2023).
- **Fleet Coordination**: Syncs AGVs and AMRs with pick-and-place workflows through a single fleet module.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed as a private company (latest major round was $83.4M Series C in 2023, per CB Insights).
- **Key Metric (Funding)**: Over $107.4M in total known equity funding (Series A: ¥75M JPY, Series B: $6M, Series C: $83.4M + $18M). Also secured ¥15.5B JPY in debt financing (Dec 2025).
