Manufacturing Engineer

Manufacturing Engineer, Manufacturing & Production
Location: Hayward, CA (on-site)

We build humanoid robots that work alongside people to solve labor shortages and create abundance.

The Role
As a Manufacturing Engineer at 1X, you will take components and assemblies for humanoid robots from prototype through volume production. You'll design, optimize, and manage manufacturing processes to ensure they are precise, repeatable, cost-effective, and reliable. This is a hands-on role that will directly impact the quality and scalability of our robotic systems.

You Will

• Develop and refine manufacturing processes for robotic mobility and control components such as actuators, drive units, precision components, motor housings, and skeletal structures

• Oversee full manufacturing workflows including fixture design, CAM programming, selection of cutting tools, and inspection/validation methods

• Deploy automation and lights-out machining strategies to enable continuous production with minimal human intervention

• Drive process improvements to reduce cycle time, increase first-pass yield, and improve reliability of robot hardware

• Collaborate with design engineering on part geometry, materials, and design changes to ensure manufacturability at every stage

• Manage change releases and product design revisions into production, focusing on scalability and consistency

• Act as technical liaison between design, machining, assembly, and quality teams for owned components

• Support build technicians and operators, maintaining work instructions and operating procedures in an up-to-date state

• Implement statistical process control (SPC) and quality monitoring practices, taking ownership of part or part family quality metrics

• Troubleshoot production issues such as tolerance stack-ups, tool wear, misalignment, and assembly variability

• Design efficient factory layouts, workflows, and test or subassembly stations optimized for speed and flexibility

• Participate in new product introduction (NPI), managing prototype, validation units, and ramp-up phases of production

Must Have

• Bachelor’s degree in Mechanical Engineering, Mechatronics, Manufacturing Engineering, or related field

• Minimum of 2 years of experience in manufacturing engineering, especially involving precision mechanical or electromechanical assemblies

• Experience with CAM programming, fixture/tooling design, and precision machining of metals or composites

• Strong understanding of design for manufacturability (DFM) and experience integrating electromechanical systems

• Familiarity with measurement techniques and standards such as GD&T, tolerance stack analysis, CMM, or other high-precision inspection methods

• Solid collaboration skills across engineering disciplines, supply chain, QA, and production teams

• Experience producing robotic actuators, joints, or other motion control systems

• Exposure to high-mix, low-volume environments with frequent design iteration

• Knowledge or experience with lean manufacturing, Six Sigma, or continuous improvement strategies

• Proficiency with CAD tools, PLM/ERP systems, and manufacturing documentation

Benefits & Compensation

• Salary Range: $90,000 – $165,000

• Health, dental, and vision insurance

• 401(k) with company match

• Paid time off and holidays
