About the role

Engineer responsible for end-to-end speaker system in wearables, including transducer selection, acoustic path design, protection, tuning collaboration, and verification across volume-constrained devices.

Responsibilities

  • Own the speaker path of a shipping consumer electronics product, from transducer selection through enclosure design and factory test
  • Translate product-level requirements into speaker system and transducer requirements: bandwidth, level, distortion, leakage, and power budget in the volume available.
  • Select, specify, and qualify speakers with suppliers, including evaluation of new and unconventional transducer technologies where they fit the product better than a conventional driver.
  • Design and simulate the acoustic path: back volume, ports and leaks, front acoustics, open-ear leakage control, mesh and sealing, in close partnership with mechanical and industrial design.
  • Build and measure prototypes; characterize frequency response, distortion, maximum output, far-field leakage, and excursion and thermal limits, and turn the results into design changes and better models.
  • Own speaker limits and protection parameters; partner with the Audio Lead on tuning and with firmware on implementation.
  • Work with the audio DSP team to minimize speaker-to-mic coupling through the frame.
  • Qualify the speaker system for reliability: sweat and ingress, temperature and humidity, drop, mesh clogging, and drift over life.
  • Set up and maintain speaker measurement methods in the lab and at the factory, including golden units, limits, and end-of-line acoustic test.
  • Support builds and factory ramps, root-cause acoustic yield and quality issues, and drive fixes with suppliers and the CM.
  • Work with the cross-functional team (EE, ME, FW, PD) to trade off acoustic performance against size, cost, and power.

Qualifications

  • Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Acoustics, Physics, or similar.
  • 5+ years of experience integrating speakers into consumer electronics hardware, with 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) and with 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, checked against measured hardware.
  • Working knowledge of speaker tuning and protection (EQ, limiting, excursion and thermal protection) and how to partner with a DSP team on it.

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
