Director of Electrical Engineering

OSI Engineering, Inc.; Palo Alto (CA); On-site; USD 180,000 - 280,000; Full time

Job summary

OSI Engineering, Inc. is seeking an experienced Electrical Engineering leader to own the wearable platform's electrical architecture for a stealth-stage neurotechnology startup. You will oversee schematic through production, integrating sensors, power management, RF, and communications on a flex PCB inside a textile beanie.

You will head a small EE team, drive DFM/DFT, coordinate overseas CM relationships, and push hardware bring-up from prototype to volume with a year-end ship target.

Qualifications

• Deep mixed-signal expertise across MCU systems, sensor AFEs, audio DSPs, image sensor interfaces, RF/wireless, and battery/charging.
• Strong SI/PI discipline with sign-off on flex and rigid-flex multi-island designs.
• Direct experience architecting and validating multi-MCU communication buses, and BOM ownership for shipped products.

Responsibilities

• Own the electrical architecture across the platform—compute partitioning, sensor integration, power, RF, and SI/PI.
• Lead schematic and PCB design for flex and rigid-flex layouts; own SI/PI sign-off across revisions.
• Architect the power tree—battery management, multi-rail regulation, USB-C charging, dynamic power budgeting.
• Own RF and wireless electrical design—antenna diversity, body-proximity tuning, Wi-Fi/BLE coexistence.
• Define and validate all communication buses—parallel and serial interfaces, audio buses, inter-MCU links.
• Drive part selection, benchmarking, and BOM ownership across MCUs, PMICs, RF SoCs, and the full electrical BOM; second-source strategy.
• Lead bring-up at the electrical layer—own SI, PI, power, and bus-level debug; unblock firmware and subsystem leads.
• DFM and qualification gates with CMs; ship the product by end of year.
• Build and lead the EE team as we scale from early test batches to production volumes.

Job description

You’ll own the electrical engineering team for a breakthrough stealth-stage neurotechnology and brain-computer interface (BCI) startup building an AI-powered neural interface platform. In this role, you will own the wearable electrical architecture from schematic through production, helping bring a highly integrated next-generation device to market. The platform combines cameras, spatial audio microphones, EEG sensors, Wi-Fi/BLE connectivity, and advanced power management on a flex PCB embedded within a textile beanie, requiring deep expertise in compact wearable system design, signal integrity, and production-ready hardware development.

What You’ll Do

• Own the electrical architecture across the platform - compute partitioning, sensor integration, power, RF, and SI/PI.
• Lead schematic and PCB design for flex and rigid-flex multi-island layouts, and own SI/PI sign-off across every revision.
• Architect the power tree - battery management, multi-rail regulation, USB-C charging, and dynamic power budgeting.
• Own RF and wireless electrical design - antenna diversity, body-proximity tuning, and Wi-Fi/BLE coexistence.
• Define and validate every communication bus on the platform - parallel and serial sensor interfaces, audio buses, inter-MCU links.
• Drive part selection, benchmarking, and BOM ownership across MCUs, PMICs, RF SoCs, and the full electrical BOM, with second-source strategy.
• Lead bring-up at the electrical layer - own SI, PI, power, and bus-level debug, and unblock firmware and subsystem leads on the way.
• Drive the design through DFM and qualification gates with our CMs, and ship the product by end of year.
• Build and lead the EE team as we scale from early test batches to production volumes.

Responsibilities:

• 10+ years designing complex consumer hardware, with at least one shipped product (wearable, audio, mobile, or comparable).
• Deep mixed-signal expertise across MCU systems, sensor AFEs, audio DSPs, image sensor interfaces, RF/wireless, and battery/charging.
• Strong SI/PI discipline with hands-on sign-off on flex and rigid-flex multi-island designs.
• Direct experience architecting and validating multi-MCU communication buses - parallel and serial interfaces, inter-processor links.
• Direct experience driving part selection, BOM ownership, and second-source strategy on a shipped product.
• Track record of leading hardware bring-up and partnering closely with firmware on debug.
• Comfortable owning overseas CM relationships and driving DFM, DFT, and DFA from prototype through volume.

Preferred Skills:

• EEG, ECoG, or other biopotential systems - especially high-channel-count or dense sensor arrays.
• Custom ASIC bring-up, silicon co-design, or in-array readout architectures.
• RF design for body-worn antennas and multi-radio coexistence.
• Founding engineer or lead-level experience at an early-stage hardware company.
