Job Description:

We are seeking an experienced and creative Senior Engineer, Mechanical to help develop the next generation of cutting-edge 3D sensing systems with Lumotive's Light Control Metasurface technology. If you're excited about designing cutting-edge hardware that powers autonomous-driving cars, advanced automation, and immersive AR/VR experience - this is your change to make it real.

You'll be a core part of a tight-knit, cross-functional team, owning everything from early concepts to fully integrated prototypes. You'll architect, design, and build mechanical systems that push the limits of what's possible - fast, lean, and built for scale.

Responsibilities:

• Own the mechanical design and development of innovative, low-cost, high performance 3D sensing systems that are ready for volume production.
• Develop mechanical architecture and create system and sub-system level designs to demonstrate differentiation enabled by Lumotive's LCM technology.
• Develop and maintain detailed 3D CAD models, GD&T-compliant drawings, and comprehensive mechanical documentation.
• Select appropriate materials, fabrication processes, assembly processes, and work with domestic and overseas vendors to build prototypes.
• Plan and execute design validation activities to ensure mechanical and thermal performance, reliability, and compliance with industry standards.
• Resolve issues related to material properties, manufacturing tolerances, and thermal management.
• Manage in-house prototyping, assembly, and testing infrastructure.
• Collaborate cross-functionally with electrical, optical, and systems engineering teams to define requirements, create project plans, and meet technical and schedule objectives.

Qualifications:

• Bachelor's degree in Mechanical Engineering or related field. Advanced degree preferred.
• 5+ years of relevant industry experience (or 3+ years with an advanced degree).
• Self-driven and adaptable; thrives in fast-paced, dynamic environments focused on breakthrough innovation.
• Expertise in mechanical CAD tools (PTC Creo and SolidWorks); experience with PDM systems (Windchill and SolidWorks PDM).
• Strong foundation in materials, thermal design, statistical tolerance analysis, functional dimensioning, and geometric tolerancing.
• Proven experience with DFM/DFA and design for thermal, vibration, shock, and ingress protection in industrial or automotive applications.
• Experience with rapid prototyping, including 3D printing, machining, sheet metal, injection molding, and compression molding.
• Full product lifecycle experience-from requirements and design through prototyping, validation, and production release.
• Comfortable working in machine shops and assembling prototypes.
• Experience with 3D sensing or LiDAR technologies is a plus.
