Lead Audio Engineer

The role

You will own the entire audio system of a wearable device. This includes the microphone array, DSP, wake-word, and spatial speaker output.

What you will do

• Own the audio system end-to-end including microphone selection, DSP pipeline, and spatial speaker output
• Drive part selection and benchmarking for microphones, DSPs, AFEs, amplifiers, and speakers
• Specify electrical and acoustic interfaces and partner with EE and FW leads
• Drive the on-device DSP including algorithm design, latency, and CPU budgets
• Validate the spatial mic array for direction-of-arrival, speech enhancement, and wind robustness
• Define the wake-word strategy and own the user experience
• Partner with product design on acoustic detailing like microphone ports and speaker housings
• Partner with the reliability lead on component-level reliability and qualification
• Ship the product by the end of year
• Help build the audio team and cloud-side voice processing capability

Required qualifications

• 10+ years of audio engineering
• At least one shipped consumer product where you owned a multi-microphone voice system end-to-end
• Deep expertise in voice DSP including beamforming, AEC, noise suppression, and direction-of-arrival
• Proven track record shipping wake-word or always-on voice activation at consumer scale
• Experience designing real-time DSP pipelines on constrained MCUs
• Strong acoustic engineering instincts
• Direct experience driving audio component selection and benchmarking with second-source planning

Nice to have

• Deploying audio DSP, wake-word, or speech models on dedicated low-power AI accelerators
• Experience with leading on-device wake-word engines
• Multi-channel audio DSPs and Class-D amplifier design
• Spatial audio rendering — HRTF, panning, head-tracked binaural
• Cloud STT pipelines and end-to-end voice UX latency budgets

Benefits

• Competitive base salary
• Meaningful equity package
• 401(k) with company matching
• Health insurance
• Flexible PTO
