Job description

Senior Opto-Mechanical Design Engineer | Mountain View, CA

Location: Mountain View, California, USA

Employment: Full-time | On-site

We are looking for a hands-on Senior Opto-Mechanical Design Engineer with strong experience in precision mechanical design and optical system integration for complex optoelectronic products.

What You’ll Do

• Develop new opto-mechanical products from concept and detailed design through engineering drawings, vendor selection, evaluation, prototype builds and production
• Design precision mechanical assemblies for silicon photonics (SiP) and optoelectronic devices
• Design and integrate free-space optical assemblies, miniature optics, optical mounts and precision alignment mechanisms
• Perform detailed tolerance analyses and tolerance stack-ups for optical and mechanical assemblies
• Design for micron and sub-micron optical alignment, including active and/or passive alignment approaches
• Design fixtures and tooling to support prototype builds through production
• Integrate mechanical, optical and electrical components into complex optoelectronic systems
• Maintain, test, evaluate and improve existing opto-mechanical products and assemblies
• Lead mechanical and opto-mechanical design reviews
• Work closely with optical, photonics, electrical, manufacturing and other cross-functional engineering teams
• Support contract manufacturers and suppliers during prototype builds, manufacturing ramp and production

What You’ll Bring

• BS in Mechanical Engineering or a related engineering discipline with 5+ years of relevant experience
• Strong hands-on opto-mechanical design experience, combining precision mechanical design with optical system integration
• Experience in detailed design, development and validation of mechanical assemblies from prototype through manufacturing
• Experience designing mechanical mounts, interfaces and assemblies for optical components such as lenses, mirrors, lasers/light sources, detectors, fibers or similar optical components
• Experience with precision optical alignment, including active and/or passive alignment; micron or sub-micron alignment experience is highly desirable
• Experience with free-space optics and miniature optical assemblies
• Strong experience with GD&T, detailed tolerance analysis and tolerance stack-ups
• Experience with DFA and integration of complex optoelectronic devices
• Understanding of how mechanical tolerances, thermal effects, vibration and assembly variation can affect optical performance and alignment
• Experience with DFM and transitioning designs from concept/prototype into manufacturing
• Knowledge of optoelectronic assembly processes such as die attach, wire bonding, active alignment and hermetic sealing
• Experience working with suppliers and/or contract manufacturers

Nice to Have

• Experience with silicon photonics, photonic integrated circuits (PICs), LiDAR, lasers, cameras or other precision optical sensing systems
• Knowledge of geometric optics and semiconductor packaging/assembly
• Experience with injection molding and precision machining
• Experience with thin/thick-film ceramics and HTCC
• Experience designing prototype or production equipment for optoelectronic manufacturing
