Lead Audio Engineer
Sabi, San Francisco
The role
You will own the entire audio system of our wearable — from the microphone array, through DSP and wake-word, to spatial speaker output. The first device carries a multi-microphone array distributed around the head and near the ears, dedicated audio DSPs and ASICs, on-device beamforming, direction-of-arrival estimation, AEC, noise suppression, wake-word detection, and open-ear speakers driven through Class-D amplifiers. The product feels alive when audio works; it dies when it doesn’t.
You will report to the Head of Hardware, with regular exposure to Sabi’s CEO and CTO, and partner closely with the EE, FW, product design, and reliability leads. You will also work extensively with external engineering teams at our contract manufacturers and audio component vendors — the work is outsourced; the accountability is yours.
What you will do
- Own the audio system end-to-end — microphone selection and placement, audio acquisition architecture, DSP pipeline, wake-word, beamforming, AEC, noise suppression, spatial speaker output.
