And many more.

We are looking for a hands-on Hardware Design Engineer to own the full hardware lifecycle - schematic capture, PCB layout, mixed signal circuit design, power architecture, bring-up, and regulatory certification - across current and next-generation hardware.

Responsibilities

Digital Hardware Design - MCU, PHY, Ethernet & PoE

Design the complete digital hardware stack: NXP i.MX RT MCU schematic and BGA layout, Ethernet PHY circuit and controlled-impedance Ethernet routing. Design and validate the IEEE 802.3af PoE front-end : PD handshake, mid/end-span bridge rectifiers, isolated flywheel buck , and optocoupler feedback regulation; analyse cross-domain IO level margins across all MCU interfaces to confirm safe driver/receiver operation.

RF & Analog Circuit Design

Design the ISM transmit chain and 2.4 GHz AoA receive chain; simulate match networks with ADS or equivalent and validate with VNA S-parameter measurements.

PCB Design & Layout

PCB layout: Define stack-up and controlled-impedance rules; route high pin-count BGAs and high-speed peripherals with length tuning; partition RF, digital, and power domains for FCC/ETSI compliance.

Power, calibration & test: Design DCDC/LDO supplies and power distribution; define hardware test procedures for RF power and frequency calibration at production.

Production Support

Failure analysis (field & manufacturing)

Yield improvement

Cost reduction

Post-Silicon Verification Support
