About the role
The Head of Sensing will own the sensing stack end-to-end, from modality to system architecture, signal acquisition and conditioning, and the interface into the ML pipeline. They will lead the sensing organization, set the multi-generation sensing roadmap, and partner closely with ML, hardware, firmware, and product teams to ship a sensing system that is performant, manufacturable, and power-efficient in a consumer wearable form factor.
Responsibilities
- Own the sensing system architecture end-to-end.
- Set the multi-generation sensing roadmap — define what each hardware generation must prove, and how the sensing subsystem evolves from current prototype units through closed beta to consumer launch.
- Own the sensing KPIs — SNR, power, thermal, repeatability across units and users — and drive the architecture choices needed to hit them.
- Partner with the ML team on the signal-to-model interface: what the model needs from the system, where to spend bits and power, and how to co-design hardware and model for product-level performance in a wearable form factor.
- Lead and grow the sensing team, composed of both electrical engineers, sensors specialists, and data scientists.
- Drive R&D on novel sensor designs and modalities — explore, prototype, and de-risk new sensing approaches that could define future hardware generations.
- Advance multimodal signal integration, fusing complementary sensing channels into a coherent system that maximizes information delivered to the model.
- Develop new SNR and signal-quality measures to rigorously quantify system performance and guide architecture decisions.
- Partner with the Head of Hardware on integration, EVT/DVT/PVT, DFM/DFT for the sensing subsystem, and with CMs/ODMs on manufacturability.
- Own regulatory readiness for the sensing subsystem in partnership with hardware.
- Communicate sensing tradeoffs clearly to the rest of the company — what we are giving up, what we are gaining, and why.
Requirements
- 10+ years of experience designing sensing systems.
- Wearables, EMG, accelerometers, UWB, mmWave, bioimpedance, ultrasound, or comparable domains are all relevant.
- Track record of taking a sensing architecture from research prototype through mass production.
- Experience leading and growing technical teams (3–10 engineers), including hiring senior ICs and managers and managing through other managers as the team scales.
- Strong systems intuition.
- Comfortable trading off across sensing, mechanical, thermal, power, and ML constraints, and explaining the tradeoffs to non-technical stakeholders.
- Demonstrated ability to co-design hardware with an ML or perception pipeline — you have shipped a product where the model and the sensor were designed together, not over the wall.
- High ownership in a small-team environment. You can set direction without a large org behind you and operate effectively when the spec is still moving.
- You are not afraid to do IC work, instead, you deeply enjoy getting into the weeds.
- Strong candidates may have Experience with non-invasive biosignal sensing (EMG, bioimpedance, or comparable modalities).
- Experience with head-worn or ear-worn form factors and the ergonomic and thermal constraints they impose.
- PhD in EE, applied physics, or a related field.
