Hardware Engineer

Job Description

Key Responsibilities:

● Lead hardware architecture for multi‐sensor wearable platforms, including power, analog front‐ends, and digital interfaces.

● Design low‐noise analog and mixed‐signal circuits for biosignal acquisition, amplification, filtering, and ADC interfacing.

● Own schematic capture and multi‐layer PCB layout in KiCad, including stack‐up definition, impedance control, DFM/DFA, and release for fabrication.

● Define and execute bring‐up/validation plans: bench testing, signal integrity, noise characterization, and environmental/reliability testing.

● Integrate sensors (ECG, EEG, SpO2, IMU, PPG, temperature, etc.) and optimize front‐end performance (gain, bandwidth, CMRR, shielding/grounding).

● Drive low‐power design (PMIC selection, power tree, sleep states, battery/charging, leakage minimization) for wearables.

● Collaborate closely with firmware/algorithms to co‐design sampling, filte...
