Lead Electrical Engineer

About the role

As the founding electrical engineering hire at Sabi, you will own the complete electrical architecture of a groundbreaking wearable that translates neural signals into text. You will work closely with hardware leadership, firmware, audio, camera, product design, and reliability teams, as well as external contract manufacturers.

Key responsibilities

• Define and own the electrical architecture across compute, sensors, power, RF, and signal integrity.
• Lead schematic and PCB design for flex and rigid‑flex multi‑island layouts and sign‑off on SI/PI.
• Architect the power tree, including battery management, multi‑rail regulation, USB‑C charging and dynamic budgeting.
• Design RF and wireless systems, handling antenna diversity, body‑proximity tuning and Wi‑Fi/BLE coexistence.
• Specify and validate all communication buses – parallel, serial, audio, and inter‑MCU links.
• Drive part selection, benchmarking and BOM ownership with a second‑source strategy.
• Lead electrical bring‑up, debugging SI, PI, power and bus issues to unblock firmware.
• Guide the design through DFM, DFT and qualification gates with contract manufacturers and ship the product by year‑end.
• Build and scale the EE team from early prototypes to production volumes.

Required profile

• 10+ years designing complex consumer hardware with at least one shipped product.
• 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.
• Experience architecting multi‑MCU communication buses and driving part selection and BOM strategy.
• Proven track record of hardware bring‑up and close partnership with firmware teams.
• Comfortable managing overseas contract manufacturers and driving DFM/DFT/DFA.

Required skills

• Schematic capture and PCB layout (flex, rigid‑flex, multi‑island).
• Power management design – battery management, multi‑rail regulation, USB‑C charging.
• RF and wireless design – Wi‑Fi, BLE, antenna tuning for body‑worn devices.
• Mixed‑signal design – MCU integration, sensor AFEs, audio DSPs, image sensor interfaces.
• Signal integrity and power integrity analysis.
• Part selection, BOM management and second‑source strategy.
• Electrical bring‑up and debug tools.

What we offer

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