Speaker Systems Engineer

San Francisco. Posted a month ago

The role

The Speaker Systems Engineer will own the speaker system in smart wearables from transducer selection to factory testing. This role involves designing acoustic paths, simulating performance, and partnering with cross-functional teams to meet product requirements.

What you will do

  • Own the speaker path of a shipping consumer electronics product
  • Translate product-level requirements into speaker system and transducer requirements
  • Select, specify, and qualify speakers with suppliers
  • Design and simulate the acoustic path
  • Build and measure prototypes
  • Own speaker limits and protection parameters
  • Work with the audio DSP team to minimize speaker-to-mic coupling
  • Qualify the speaker system for reliability
  • Set up and maintain speaker measurement methods in the lab and at the factory
  • Support builds and factory ramps

Required qualifications

  • Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Acoustics, Physics, or similar
  • 5+ years of experience integrating speakers into consumer electronics hardware
  • At least one shipped product where you owned the speaker system
  • Strong grounding in electroacoustics: lumped-parameter modeling, Thiele/Small parameters, enclosure and port design, and the behavior of small drivers at their limits
  • Hands-on experience specifying and qualifying miniature speakers with transducer suppliers
  • Extensive experience with audio test systems (e.g., SoundCheck, Klippel, Audio Precision)
  • Experience measuring distortion, maximum SPL, and rub-and-buzz
  • A record of using acoustic simulation (lumped-parameter and FEM, e.g., COMSOL) to make design decisions
  • Working knowledge of speaker tuning and protection (EQ, limiting, excursion and thermal protection)

Nice to have

  • Masters or Ph.D. in EE, ME, Acoustics, or related disciplines
  • 8+ years of experience in speaker or transducer development for consumer electronics
  • Experience with wearables, hearables, or other products where the speaker sits close to the ear and the acoustic volume is measured in fractions of a cubic centimeter, including open-ear designs
  • Hands-on experience with a range of transducer technologies beyond conventional moving-coil drivers
  • Transducer design experience: motor, diaphragm, and suspension design, or close work with a supplier’s design team
  • Proficiency in a high-level programming language (e.g., MATLAB, Python) for measurement automation and analysis
  • Familiarity with human perception of sound and psychoacoustic evaluation of speech quality and intelligibility
  • Experience with factory acoustic test development and yield analysis at a contract manufacturer

Benefits

  • 401 (k) max employer match: 3.5% of compensation
  • 100% employer-paid health, vision, and dental benefits for you and your dependents
  • Unlimited PTO and sick time
  • Flexible spending account with employer matching up to $1,650/year (medical FSA)
  • Guardian Employee Assistance Program (EAP)
  • Opportunity to share in the company's success with competitive stock options
