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 Structural Dynamics & Validation team ensures that NEO performs reliably, quietly, and safely in the real world. We combine advanced simulation, experimental testing, and cross-functional engineering to improve durability, structural integrity, vibration performance, and control stability across the robot platform.
Working at the intersection of mechanical engineering, controls, systems engineering, and hardware validation, the team plays a critical role in delivering robots that withstand demanding operating conditions while providing a refined user experience.
Your Charter
Own the structural dynamics and validation strategy for robotic subsystems by translating operational requirements into validated engineering models and test methodologies.
You will define the structural loading environment, develop simulation and experimental validation methods, and ensure hardware designs meet demanding requirements for shock, vibration, durability, acoustic performance, and control stability throughout the product lifecycle.

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.
Successful Structural Dynamics & Validation Engineers combine deep analytical expertise with a practical engineering mindset. They are equally comfortable building simulation models, instrumenting hardware, analyzing complex test data, and collaborating across disciplines to solve challenging system-level problems. They are driven by curiosity, rigor, and the pursuit of engineering excellence, ensuring every design performs reliably under real-world operating conditions.
