Senior​/Staff Loads & Dynamics Engineer

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.

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.

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.

• Define statistically representative load cases that accurately model real-world robotic operating conditions
• Develop and maintain validated structural dynamics, shock, and vibration models that correlate with experimental test data
• Improve robot durability, NVH performance, and control stability through structural analysis and engineering recommendations
• Lead structural validation efforts including instrumentation, data acquisition, testing, model correlation, and reporting
• Identify, investigate, and resolve structural dynamics issues affecting vibration, acoustic noise, fatigue life, or system stability
• Partner with mechanical, controls, systems, and reliability engineers to continuously improve robot performance throughout development

• Deep understanding of structural dynamics, vibration analysis, modal behavior, and dynamic system response
• Strong analytical skills with the ability to translate physical testing into validated engineering models
• Expertise in experimental testing, instrumentation, data acquisition, and model correlation
