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

Build tooling and automation (Python/Bash/C++) to reduce manual release preparation work

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

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 release notes and release visibility by understanding how users consume releases and implementing improvements to increase adoption and usage awareness

Drive practical AI usage in release workflows (e.g. release note drafts, change aggregation)

Minimum Requirements

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

Practical experience designing and operating production release workflows

Strong understanding of system-level testing and release QA

Experience working with planning or tracking tools (e.g. Jira or equivalents)

Experience working cross-functionally and taking ownership of ambiguous initiatives

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
