Mechanical Designer - Airborne

About Matter IntelligenceWelcome 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 built core infrastructure at OpenAI. We are now building the next generation of space- and airborne-based sensing systems.About the RoleMatter is hiring a Mechanical Designer focused on airborne payload hardware. This role will turn engineering concepts into detailed, manufacturable designs and support hardware from early packaging through fabrication, assembly, integration, and flight testing.Key ResponsibilitiesCreate and maintain detailed mechanical designs, assemblies, drawings, and bills of material for airborne payload hardware.Translate system, optical, electrical, thermal, and structural constraints into practical packaging solutions.Apply sound design-for-manufacture and design-for-assembly practices while working closely with suppliers and internal <builders.Support> prototype builds, fit checks, integration, test-fixture development, and hardware troubleshooting.Maintain configuration discipline and incorporate lessons from fabrication, test, and flight operations into design updates.QualificationsRequiredExperience producing detailed mechanical designs and release-ready engineering drawings for complex hardware.Strong working knowledge of mechanical packaging, tolerancing, materials, and manufacturing processes.Ability to collaborate with engineers across optical, electrical, structural, thermal, and systems disciplines.Hands-on judgment and attention to detail through fabrication, assembly, and integration.PreferredExperience with airborne, aerospace, precision-instrument, robotics, or other mass- and volume-constrained hardware.Experience packaging optical and electronic components with tight alignment or environmental requirements.Familiarity with rapid prototyping and low-volume production environments.What Success Looks LikeDesigns are complete, manufacturable, and released on time with clear configuration control.Hardware assembles and integrates as intended with minimal avoidable <rework.Design> updates incorporate evidence from build, test, and flight operations quickly and accurately.LocationThis role is based in El Segundo, CA, and requires onsite work.ITAR RequirementsTo comply with U.S. export regulations, applicants must be one of the following:A U.S. citizen or nationalA lawful permanent resident (green card holder)Eligible to obtain required authorizations from the U.S. Department of StateEmployee Offerings and BenefitsAt Matter, we believe in rewarding high performance and providing the support you need to thrive. Our compensation and benefits package includes:Competitive compensation based on experienceEarly-stage equity package100% employer-paid health, dental, and vision coverageOpportunity to work on novel sensing, data, and AI systems with real-world deployment paths to the largest industries in the worldMatter Intelligence is an equal opportunity employer.
