Staff Loads & Dynamics Engineer
Kind Humanoid
San Carlos, CA, USA
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 a 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 plays a critical role in ensuring 1X robots can operate reliably, quietly, and safely in real-world environments. We combine advanced simulation, testing, and cross-functional engineering collaboration to improve durability, control stability, and product performance across the robot platform. This team sits at the intersection of hardware, controls, and systems engineering, directly shaping the reliability and user experience of next-generation humanoid robotics.
Your Charter:
Own the structural dynamics and validation strategy for robotic subsystems by translating operational requirements into validated engineering models and test methodologies. This role is critical to 1X’s ability to deliver robust, high-performing robots by ensuring designs meet demanding requirements for shock, vibration, durability, and control stability throughout the product lifecycle.
Key Outcomes:
Define and maintain statistically significant load cases that accurately represent real-world robotic operating conditions across critical sub-assemblies.
Deliver validated shock and vibration models that correlate with physical test data and remain aligned with rapid design iterations.
Improve product durability, NVH performance, and control stability through structural dynamics analysis and cross-functional design feedback.
Lead structural validation activities from instrumentation strategy through data acquisition, analysis, and model correlation.
Identify and resolve structural dynamics issues contributing to instability, vibration, or acoustic noise in robotic systems.
Job requirements
Minimum Requirements:
Strong foundation in structural dynamics, vibration, and durability engineering.
Experience using commercial FEA tools such as ANSYS or Abaqus for harmonic and transient dynamic analysis.
Proven experience validating analytical models using empirical test data.
Hands-on experience setting up and executing structural test campaigns, including instrumentation and DAS workflows.
Experience analyzing shock and vibration performance in multi-material systems including metals and polymers/plastics.
Preferred Skills:
Experience working on robotic, automotive, aerospace, or other highly dynamic electromechanical systems.
Familiarity with acoustic noise reduction and advanced NVH optimization techniques.
Experience supporting controls teams through structural dynamics characterization and stability troubleshooting.
Exposure to fast-paced hardware development environments with rapid design iteration cycles.
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: $207,000 - $253,000
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
