Staff Loads & Dynamics Engineer
About The Position
1X is building humanoid robots designed to work in homes, handling chores and tasks to give people their time back. This requires solving complex problems in robotics, AI, and manufacturing simultaneously, at scale, and in a safe form factor for family environments. The company has been developing these robots since 2014 and is now focused on shipping its flagship product, NEO, a home robot designed for real-world operation alongside people. 1X is seeking individuals inspired by this mission to join their scaling team and contribute to changing how humans spend their time by safely creating abundance. The Structural Dynamics & Validation team is essential for ensuring 1X robots operate reliably, quietly, and safely in real-world settings. The team utilizes advanced simulation, testing, and cross-functional collaboration to enhance durability, control stability, and overall product performance. This role is at the intersection of hardware, controls, and systems engineering, significantly influencing the reliability and user experience of next-generation humanoid robots. The Staff Loads & Dynamics Engineer will be responsible for the structural dynamics and validation strategy of robotic subsystems. This involves translating operational requirements into validated engineering models and test methodologies. The role is crucial for delivering robust, high-performing robots by ensuring designs meet stringent requirements for shock, vibration, durability, and control stability throughout the product lifecycle.
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.
Nice To Haves
- 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.
Responsibilities
- 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.
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
