## Job description

## About 1X

We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it’s not. To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you’re inspired by this, you’ll thrive here. We’ve been at this since 2014 and we’re at the point where the hard problems are behind us and the hard work is in front of us. NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We’re not demoing it - we’re shipping it. We’re excited to meet you, if this excites you. If you’ve spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We’re scaling, we’re hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.

## About the Team

The Tooling team builds the tools, pipelines, and infrastructure that speed up iteration and give us confidence our software works properly before it reaches physical robots. We own the build, release, and continuous integration infrastructure that powers robotics software across core OS, motion, AI, embedded systems, cloud services, apps, and simulation. As our engineering organization scales, this team is critical to reducing developer friction, increasing release quality, and enabling rapid deployment of software to both simulation environments and physical robots.

## Your Charter

Own and scale the automated build and release infrastructure that powers software development across 1X. You will design highly reliable CI/CD systems, optimize build performance, improve release automation, and establish engineering workflows that enable teams to ship software safely and efficiently across robotics, cloud, embedded, and simulation platforms.

## Key Outcomes

- Design and scale automated build and release pipelines that support rapid software delivery across the entire software stack (embedded to cloud).
- Improve build reliability, build performance, and deployment efficiency while reducing engineering downtime and release risk.
- Develop automated testing, artifact management, versioning, and release validation systems that ensure software quality before deployment.
- Partner with all software teams to standardize development workflows and improve engineering productivity.
- Establish scalable developer infrastructure, release governance, and CI/CD best practices that support the continued growth of 1X's engineering organization.

## Key Competencies

- Deep expertise building large-scale CI/CD, build automation, and release engineering systems.
- Strong systems thinking with experience designing reliable developer infrastructure for complex software environments.
- Excellent software engineering skills with a focus on automation, scalability, and operational excellence.
- Strong understanding of software release lifecycle management across multiple platforms and engineering teams.
- Ability to lead technical initiatives and drive engineering productivity in a fast-paced startup environment.

## Minimum Requirements

- 6+ years of professional experience (Senior) or 10+ years (Staff) in Build Engineering, Release Engineering, Developer Infrastructure, DevOps, or Platform Engineering.
- Bachelor's degree in Computer Science, Software Engineering, or a related technical field.
- Strong programming experience in Python, Go, Bash, or similar scripting and automation languages.
- Hands-on experience building and maintaining CI/CD systems using tools such as Jenkins, GitHub Actions, GitLab CI, Buildkite, Bazel, Buck2, CMake, or similar build systems.
- Experience supporting Linux-based development environments and distributed software engineering teams.

## Preferred Skills

- Experience supporting robotics, embedded systems, autonomous vehicles, games, or other large-scale software platforms.
- Familiarity with cross-platform build systems, embedded firmware builds, or multi-language monorepos.
- Experience with containerization technologies such as Docker and Kubernetes.
- Experience managing artifact repositories, package management, release orchestration, and deployment automation.
- Familiarity with cloud infrastructure platforms such as AWS, GCP, or Azure.
- Experience optimizing build performance, distributed compilation, caching strategies, or large-scale developer tooling.

What does a successful 1X Team Member look like: Team members at 1X who thrive here are builders. They move fast, own their work completely, and treat time like it’s the one thing you can’t get back - because it is. They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask. We push each other to be better, and we do it with honesty and respect.

## Compensation Range

$190,000 – $230,000 + Equity

## Benefits

- Comprehensive medical, dental, and vision coverage
- Generous paid time off, company holidays, and parental leave
- 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
- Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
- Commuter benefits (transit and parking)
- Short-term and long-term disability, and life insurance
- Employee Assistance Program (EAP) for mental health, financial, and personal support
- Onsite snacks and catered lunches
