$8,454 more — $158,454 — moves this role to Level III and 3 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 $158,454 would place this position at wage Level III. That figure is within the posted range, and I'd like to target it. This role classifies under "Mechanical Engineers" for prevailing-wage purposes.

About the role

  • The Test & Validation team makes sure NEO can withstand the real-world conditions it will encounter in homes.

Responsibilities

  • NEO is our flagship - a general purpose 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

  • Bachelor's degree in Mechanical Engineering or a closely related engineering discipline.
  • 2-4 years of experience designing mechanical test fixtures, assembly fixtures, tooling, or similar custom hardware.
  • Strong 3D CAD and 2D engineering drawing skills, with experience designing parts and assemblies for machining, fabrication, or rapid prototyping.
  • Experience designing fixtures for robotics, electromechanical systems, automotive, aerospace, consumer hardware, or other complex physical products.

Nice to have

  • Preferred Skills:

Skills

  • Experience using hand calculations or FEA to evaluate fixture strength, stiffness, deflection, or dynamic behavior.
  • Hands-on experience assembling and bringing up test fixtures in a laboratory or engineering environment.
  • Experience integrating sensors, actuators, wiring, or instrumentation into mechanical test fixtures.
  • Experience with vibration, mechanical actuation, thermal, or environmental testing.
  • 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.
  • Excellent CAD and engineering drawing skills with a strong understanding of tolerancing, materials, mechanical interfaces, and hardware.

Compensation

  • $150,000- $170,000

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

  • We build and operate the test infrastructure, fixtures, and validation systems that allow engineering teams to understand how the robot performs, where it fails, and what needs to improve before it reaches customers.
  • As a Test Fixture Design Engineer, you'll work at the intersection of mechanical design, test engineering, and hands-on hardware.
  • You'll design the fixtures that make rigorous, repeatable testing possible - from understanding the device under test and defining load paths to designing, manufacturing, assembling, and iterating the final hardware in the lab.
  • Your Charter:
  • Design and deliver the mechanical test fixtures that enable safe, accurate, and repeatable validation of NEO and its critical subsystems.
  • You'll own fixture development end-to-end, from understanding the test objective and developing the initial concept through CAD, drawings, fabrication, assembly, test-cell installation, and iteration based on real-world test results.
  • Your designs should be robust and easy to manufacture, while minimizing unnecessary complexity, cost, and test-induced artifacts.
  • Key Outcomes:
  • Deliver production-ready mechanical test fixtures on schedule that enable Test & Validation to execute critical validation and reliability testing across NEO hardware.
  • Develop fixture designs that provide the required strength, stiffness, accuracy, repeatability, and safety without introducing unwanted constraints or artifacts into test results.
  • Own complete fixture design packages, including 3D CAD, 2D drawings, materials, tolerances, hardware, interfaces, and assembly requirements.
  • Drive successful manufacturing handoff by working directly with internal fabrication teams and external vendors to resolve DFM issues, manage quotes and lead times, and deliver hardware to test schedules.
  • Bring fixtures from CAD into the lab through hands-on assembly, fit checks, installation, and test setup, rapidly iterating designs based on test-cell feedback.
