Mechanical Drafter

Welcome to Matter, where we are building the future of vision AI: pairing a world-first sensor that sees molecular chemistry, temperature, and 3D shape with a Large World Model that will be the most powerful intelligence engine for the physical world. This system doesn't just see what something looks like; it understands everything from a single pixel. We call this Superintelligent Vision.

Our team has delivered technologies to Mars for NASA/JPL, designed advanced sensors for U.S. Defense, and frontier artificial intelligence systems. We are now building the next generation of space- and airborne-based sensing systems.

Matter is hiring a Mechanical Drafter to turn conceptual mechanical designs into precise, release-ready drawings for airborne optomechanical and optoelectrical payload hardware. This role partners closely with engineering, manufacturing, supply chain, and suppliers to ensure hardware is accurately documented, manufacturable, and cost-effective.

• →

  Detail conceptual designs and generate precise 3D CAD models, assembly drawings, part drawings, and bills of material for optical and optoelectrical assemblies, including lens housings, fixtures, mounts, and alignment mechanisms.

• →

  Perform tolerance analyses and select materials to ensure precision mechanical designs meet optical, performance, manufacturability, and reliability requirements.

• →

  Work with optical engineers to translate system-level optical requirements into robust mechanical designs; collaborate with manufacturing, supply chain, and suppliers to optimize drawing packages and designs for manufacturability and cost.

• →

  Support prototype builds, fit checks, integration, and hardware troubleshooting by resolving drawing, tolerance, and configuration issues.

• →

  Maintain configuration discipline, drawing release quality, and revision control; incorporate lessons from fabrication, assembly, and test into drawing updates.

To comply with U.S. export regulations, applicants must be one of the following:

• A U.S. citizen or national

• A lawful permanent resident (green card holder)

• Eligible to obtain required authorizations from the U.S. Department of State

• Demonstrated proficiency producing detailed mechanical drawings and documentation for precision assemblies.

• Strong proficiency with NX or an equivalent CAD tool; deep understanding of precision mechanical design, ASME Y14.5-2018 GD&T, tolerance stack-ups, materials, and manufacturing processes.

• Experience creating drawings for optical-system components such as lenses, lasers, sensors, and imaging assemblies; ability to collaborate effectively with optical engineers and manufacturing partners.

• Ability to communicate drawing requirements, tolerances, and technical updates clearly to engineering, manufacturing, supply chain, and suppliers.

• Experience supporting optical, optoelectrical, aerospace, or precision-instrument assemblies.

• Experience preparing drawing packages that support optical alignment, precision assembly, and inspection.

• Familiarity with prototype and low-volume manufacturing environments, including supplier and manufacturing feedback loops.

• Drawing packages are complete, accurate, manufacturable, and released on time with clear configuration control.

• Optical and optoelectrical assemblies build and integrate as intended with minimal avoidable rework.

• Drawing updates incorporate evidence from fabrication, assembly, and test quickly and accurately.

This role is based in El Segundo, CA, and requires onsite work.
