Sponsors, but it's cap-subject — you still face the weighted lottery (~45% per draw at Level III). Good if you win; have a cap-exempt backup on your list.
Lottery odds assume a STEM candidate.

the lottery is wage-weighted — each level is one more entry
The bottom of this range ($107,700) is below the Level I prevailing wage of $110,510. An H-1B cannot be filed below the prevailing wage, so an offer at the floor of this band could not be sponsored as posted.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $134,493 would place this position at wage Level II. That figure is within the posted range, and I'd like to target it. This role classifies under "Mechanical Engineers" for prevailing-wage purposes.
DOL prevailing wage, 2026-27 wage year · Mechanical Engineers (17-2141) · San Francisco-Oakland-Fremont, CA. Wage level is derived by USCIS from the offered wage, occupation and worksite; the occupation shown is inferred from the job title.

About the role
- Successfully integrate mechanical, electrical, sensing, and electromagnetic components into complete actuator systems
- Hands-on engineering mindset with an interest in assembling, testing, troubleshooting, and improving physical systems
- Strong mechanical intuition around tolerances, fits, materials, bearings, shafts, and structural interfaces
Responsibilities
- We're building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back.
- NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people.
- 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.
- Our work spans mechanical design, electric motors, sensing, power transmission, controls integration, and hardware validation.
- We work closely with electrical, controls, firmware, test, and manufacturing teams to rapidly develop actuator concepts, validate performance, and mature designs into reliable systems that can be produced at scale.
- Design and integrate the mechanical systems that enable high-performance robotic actuation.
- You will contribute to actuator development from early concepts and technical viability decisions through detailed design, prototyping, testing, and manufacturing readiness.
Requirements
- Bachelor's or Master's degree in Mechanical Engineering or a related technical field
- 2-5 years of experience in mechanical design, product development, or a related engineering role
- Strong proficiency with CAD tools such as SolidWorks, Onshape, Inventor, or equivalent
- Experience creating production-quality engineering drawings and mechanical documentation
- Strong understanding of tolerances, fits, materials, and mechanical design fundamentals
- Ability to work effectively in a fast-paced, multidisciplinary engineering environment
Skills
- Familiarity with electric motors, magnets, laminations, air gaps, encoders, or electromagnetic components
- Experience with bearings, gears, shafts, transmissions, and structural actuator components
- Exposure to rapid prototyping and iterative hardware development cycles
- Strong collaboration and communication skills across mechanical, electrical, controls, test, and manufacturing teams
Compensation
- $107,700 - $161,500 + Equity
Benefits
- Comprehensive medical, dental, and vision coverage
- Generous paid time off, company holidays, and parental leave
- 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
Company info
- Design and release actuator components and assemblies that meet performance, packaging, reliability, and manufacturability requirements
- Deliver accurate CAD models, engineering drawings, BOMs, tolerance definitions, and interface documentation
- Improve actuator performance and durability through rapid prototyping, testing, failure analysis, and design iteration
- Support the transition of actuator designs from early prototypes into repeatable, production-ready hardware
- Strong mechanical design fundamentals with the ability to create practical and manufacturable hardware
- Curiosity about electric motors, electromagnetic systems, and multidisciplinary actuator design
- 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.
