Depth Hardware Laser Safety Design Engineer

Santa Clara Valley (Cupertino), California, United States


Role Number:200041608
The Depth Hardware group at Apple develops depth-sensing hardware such as the revolutionary True-Depth camera that powers FaceID. This multi-disciplinary group of engineers are responsible for architecture, research, and manufacturing development of these highly complex sensing systems for Apple products. The Depth Hardware team is seeking a Depth Hardware module design engineer for enabling optical safety for laser based optical modules for depth applications.

Key Qualifications

  • This role requires ability to learn and explore new areas quickly and take responsibility for project success amid high ambiguity. Ability to work/lead/communicate in a highly matrixed/dynamic environment is a requirement. Ideal applicant will have direct experience in 4-5 of the areas listed below and have some knowledge of the others.
  • Opto-electronic / laser module hardware fail-safe mechanisms design
  • Laser module sub-component definition to guarantee optical safety (solid state lasers, free space optical elements, on-chip laser drivers)
  • Laser safety architecture definition via Fault Tree Analysis (FTA) and Design Failure Modes and Effect Analysis (D-FMEA) of complex systems
  • Optical simulation and system modeling tools such as Matlab, LightTools, Zemax etc.
  • High volume manufacturing of consumer electronics (optical preferred)
  • Expertise in manufacturing statistics / Monte Carlo
  • Design, setup and execution of complex optical experiments
  • C++, C#, Matlab, JMP or Python programming for equipment control, automated data collection and analysis
  • Laser safety classifications and specifications (IEC 60825-1 etc.)
  • Strong training in physics and proven track record of analytical thinking


The primary responsibility is end to end laser safety ownership for laser based optical modules from module architecture/design through validation and delivery in high volume. It involves: • Architecture/design of highly robust active & passive fail-safe mechanisms for mitigating optical hazards • Optical simulation (LightTools / Zemax) and experimental lab validation to demonstrate effectiveness of optical safety mechanisms • Performing FTA and DFMEA as design tools to define hazards for system use case and defect scenarios • Being up to date with latest industry laser safety specifications such as IEC60825-1 etc. • Component, module and system level process, design and spec funneling to enable manufacturability in high volume • Heavy interaction with multidisciplinary design teams (system, optical, electrical, mechanical, process, test, product safety, external consultants, firmware, software, operations etc.) covering a wide breadth of engineering and technical principles

Education & Experience

• MS or PhD degree in Physics, Electrical or Mechanical Engineering • 2+ (PhD) or 5+ (MS) years of industry experience in development and high volume deployment of electro-optical modules
