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 Manufacturing team is where NEO goes from CAD files to physical reality. Every robot that ships to a customer's home passes through our hands first, and the precision of our work directly determines whether NEO performs safely and reliably in the real world. This team is critical to 1X's mission - without us, there is no robot, no shipment, and no abundance to create.

Your Charter

To create an abundant supply of physical labor through safe, intelligent humanoids, every single NEO must be built to a standard that earns its place in someone's home. As an Assembly Technician, you are responsible for translating engineering intent into a physical robot - building precision mechanical subassemblies that meet exacting tolerances so NEO can move, learn, and operate safely alongside real people. Your craftsmanship is the foundation that everything else - AI, software, customer trust - is built on.

Key Outcomes

• Consistently meet daily and weekly production output targets without compromising on quality or safety standards

• Deliver subassemblies that pass first-time inspection, minimizing rework and downstream defects

• Maintain dimensional accuracy and proper torque specifications across every assembly you complete

• Identify and escalation process issues, tooling problems, or recurring defects so the line gets better over time

• Contribute to a clean, organized, and safe work area that meets ESD and manufacturing standards every shift

Key Competencies

• Craftsmanship mindset - you take pride in building things correctly and care how the work turns out, not just that it's done

• Strong manual dexterity and comfort with detailed, repetitive precision work on small parts

• Reads engineering drawings fluently and works from written instructions without needing constant direction

• Reliable and accountable - shows up on time, finishes what they start, and supports the team to hit shared goals

• Quality-first instinct - would rather flag a defect than let it pass

Minimum Requirements

• 2+ years of experience in mechanical assembly or manufacturing

• Ability to read and follow assembly drawings, work instructions, and engineering documentation

• Proficient with hand tools, power tools, and basic measuring instruments (calipers, torque wrenches, gauges)

• Able to lift up to 50 lbs and perform sustained hands-on, physical work throughout a shift

• Reliable, punctual, and able to work effectively in a team environment

• Professional-level English proficiency (written and verbal)

Preferred Skills

• Experience assembling robotics, aerospace, medical device, or other precision mechanical products

• Familiarity with ESD procedures and controlled manufacturing environments

• Experience with high-mix, low-volume or early-stage production environments where processes are still being refined

• Exposure to lean manufacturing or continuous improvement practices

What does a successful 1X Team Member look like

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.
