Lead Product Designer

Sabi•San Francisco, CA

About The Position

We are a small team solving one of the hardest problems in human-computer interaction: a noninvasive wearable that turns thought into text, no surgery required. By pairing ultra-high-density neural sensing with our Brain Foundation Model, we decode neural signals with a fidelity once reserved for implants. Our mission is to give a billion people a direct link between mind and machine - expanding how humans think, communicate, and create. We are building a next-generation AI companion wearable powered by EEG/BCI technology. Our device reads and responds to neural signals in real time, creating a deeply personal experience that adapts to each user. This is not another productivity tool or a gadget — it is a new category of technology built around human potential. We are backed by strong investors, moving fast, and assembling a world-class team to bring this to market. If you thrive at the frontier of what’s possible and want to build something that genuinely changes how people interact with their own minds, we want to talk to you.

Requirements

10+ years of industrial design and/or mechanical engineering, with multiple shipped consumer wearables or comparable body-worn products.
Demonstrated experience integrating electronics into soft goods or textile products (apparel, headwear, garments, or wearables with significant fabric content).
Deep CAD proficiency (SolidWorks, Fusion 360, Rhino, or equivalent) and rendering (Keyshot or comparable).
Strong instinct for comfort engineering: pressure points, weight, thermal, fit across diverse users, backed by structured wear testing and iteration.
Experience driving DfM, tooling, and quality with overseas CMs.

Nice To Haves

High-density biocompatible interfaces, dry electrode arrays, or other dense sensor-to-skin integrations.
Soft goods sourcing and textile engineering: knit beanies, technical apparel, woven goods.
Optical windows, acoustic ports, or sensor windows in consumer products.
Biocompatibility, skin contact, and dermatological testing for body-worn products.
A point of view about what makes a wearable beautiful rather than gadget-y.

Responsibilities

Own ID and ME for the wearable end-to-end: sketch through CAD, prototype, tooling, and DfM with overseas CMs.
Lead the integration of electronics into soft goods: flex PCB packaging, rigid-island placement, textile-to-rigid transitions, weight distribution, thermal management, serviceability
Define and enforce comfort engineering: pressure mapping, weight balance, skin-contact thermal limits, breathability, fit across head sizes and hair types, long-wear validation.
Drive the design language and material story for our brand's physical products: fabrics, seams, transitions, how the device announces itself or fades into the background.
Partner with the EE lead on rigid-island layout, antenna keep-outs, and electrode contact pressure; with audio and camera leads on acoustic ports, mic mesh, lens windows, and pod integration.
Partner with the reliability lead on drop, ingress, thermal, and ergonomic robustness.
Ship the product by end of year, and build and lead the product design function as ID and ME capability scales.
