Role
- Develop new opto-mechanical products from concept and detailed design through engineering drawings, vendor selection, evaluation, prototype builds and production
- 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
- Integrate mechanical, optical and electrical components into complex optoelectronic systems
- Lead mechanical and opto-mechanical design reviews
- Work closely with optical, electrical, manufacturing and other cross-functional engineering teams
- Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team.
Requirements
- B.S. or M.S in mechanical, aerospace engineering or equivalent
- 5+ years of 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
- Experience working with suppliers and/or contract manufacturers
- A passion for hardware development, including working in a fast-paced environment with hands-on design and development
- A motivated leader who has experience mentoring and supporting junior engineers
- Understanding of how mechanical tolerances, thermal effects, vibration and assembly variation can affect optical performance and alignment
- Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria
Bonus
- Experience running a development program while delegating to a small team
- Experience in synthesizing requirements and flowing them down to sub-scale verification builds and testing
- Knowledge of geometric optics and semiconductor packaging/assembly
- Experience designing prototype or production equipment for optoelectronic manufacturing
- Experience managing a team of engineers
