# Release Engineer at Mujin

- **Company:** Mujin
- **Location:** Tokyo, Japan
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2026-05-11
- **Last confirmed live:** 2026-09-09
- **Apply:** https://jobs.lever.co/mujininc/4080a32f-1010-4d5c-ac04-b16529a9ce85

## 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 Role

Mujin is hiring a Release Engineer for a growing team to focus on shaping and building scalable, reliable processes for software packaging, validation, and delivery rather than just building features. Regular releases are critical to maturing MujinOS as a product, ensuring consistent quality and completeness across complex systems. Turning ongoing development into stable, releasable versions requires not only coordination, but also development of internal tooling, workflows, and automation systems. In this role, you will make releases more predictable, efficient, and scalable by designing and developing release workflows, internal tools, and quality gates—while staying hands-on with release-stage QA and integration validation. You will work closely with engineers responsible for our core software systems, QA, and documentation owners, helping ensure that what is built can be confidently released, clearly understood, and effectively used by both internal teams and end users.

## Responsibilities

- Work with stakeholders to better understand our end users' needs for issue tracking and management and help improve and maintain the issue tracking tools/systems and workflows
- Help improve and evolve existing end‑to‑end release processes and workflows
- Participate hands‑on in release-stage integration and regression QA
- Help define and uphold release quality gates together with developers and QA
- Help improve release notes and release visibility by understanding how users consume releases and implementing improvements to increase adoption and usage awareness
- Create tooling and automation (Python/Bash/C++) to reduce manual release preparation work
- Drive practical AI usage in release workflows (e.g. release note drafts, change aggregation)

## Minimum Requirements

- Practical experience designing and operating production release workflows
- Strong understanding of system-level testing and release QA
- Experience working cross-functionally and taking ownership of ambiguous initiatives
- Experience working with planning or tracking tools (e.g. Jira or equivalents)
- Hands-on experience developing tools or automation using languages such as Python or C++
- Ability to build scripts, tools, or systems to improve release workflows, QA processes, and automation

## Preferred Requirements

- 5+ years of hands-on experience in Release Engineering or similar roles (e.g. Release Engineer, Product Enablement, DevEx, release-focused DevOps)
- Experience with AI tools in software delivery or documentation workflows
- Background in environments with remote or limited deployment control

Interview Process

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

Attractives

- Own and define the release function from the ground up, rather than inheriting a fixed framework
- Drive high-impact improvements in developer productivity, release efficiency, and overall product quality
- Take on a hands-on, builder role with strong influence across engineering, QA, and documentation
- Opportunity to design and implement AI-powered solutions in real production release workflows

## 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).
