Level IV$182,4374 entries

$7,437 more — $182,437 — moves this role to Level IV and 4 lottery entries. That figure is inside the range the employer already advertised.

Based on the DOL prevailing wage for this occupation and worksite, a base salary of $182,437 would place this position at wage Level IV. 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

  • The Prototyping team helps turn ideas into physical reality across some of the most varied hardware projects at 1X.
  • You may be designing a mechanical prototype one week, coordinating fabrication the next, and testing or iterating on a completely different product shortly after.
  • Adaptability: You can context-switch between very different projects and are comfortable working outside a narrow engineering specialization when the project requires it.

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.

Requirements

  • 5+ years of experience in mechanical engineering, product development, prototyping, or a similar hands-on hardware development role.
  • Experience independently managing multiple hardware projects with competing priorities.
  • Bachelor's degree in Mechanical Engineering or a related technical field, or equivalent practical experience.

Nice to have

  • Preferred Skills:

Skills

  • Hands-on experience with rapid prototyping processes such as 3D printing, machining, sheet metal, casting, or other fabrication methods.
  • What does a successful 1X Team Member look like:
  • They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask.

Compensation

  • $175,000-215,000

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

  • While other engineering teams may focus deeply on a specific subsystem of NEO, this team works across accessories, shop products, internal ecosystem projects, and the hardware needed to support the broader NEO experience.
  • If you enjoy variety, ownership, and building things from the ground up, this is a team where you will have a direct impact.
  • Your Charter: Own the end-to-end development of physical products and prototypes that support the NEO ecosystem beyond the core robot.
  • You will take projects from unclear requirements through design, prototyping, fabrication, testing, and iteration, working directly with stakeholders and internal and external resources to deliver practical, high-quality solutions.
  • Your work will help 1X rapidly develop the accessories, products, tools, and supporting hardware required to bring NEO into the real world and into people's homes.
  • Key Outcomes:
  • Deliver functional, validated prototypes and products from concept through fabrication and testing, balancing speed, quality, cost, and performance.
  • Independently drive multiple projects simultaneously, establishing requirements, priorities, and execution plans even when the initial problem is ambiguous.
  • Develop practical mechanical designs that can be rapidly prototyped, tested, iterated, and transitioned to appropriate manufacturing methods when needed.
  • Build strong working relationships with internal stakeholders, machine shops, vendors, and other fabrication resources to ensure projects move quickly from design to physical hardware.
  • Identify issues through hands-on testing and iteration, using learnings to improve design performance, reliability, usability, and manufacturability.
  • Key Competencies:
