We partner with TI, NXP, Renesas, and Analog Devices to deliver market-leading solutions.

THE ROLE

We seek an exceptional Senior Hardware Engineer to lead end-to-end hardware development on challenging, non-monotonous R&D projects. You'll own the complete hardware lifecycle—from requirements to manufacturing—across multiple industries. You'll mentor junior engineers and collaborate with firmware, mechanical, and test teams.

KEY RESPONSIBILITIES

• Own complete hardware development: architecture, schematic design, PCB layout (up to 8-layer), prototyping, validation, manufacturing support

• Design signal integrity-critical circuits with mixed-signal interfaces and power distribution systems

• Integrate advanced SoCs (ARM Cortex, TI, NXP) for IoT products with edge computing capabilities

• Drive FCC, CE, and FDA/ISO 13485 compliance

• Select optimal components and manage supply chain

• Mentor junior hardware engineers on design best practices

• Collaborate across firmware, mechanical design, test engineering, and manufacturing teams

REQUIRED EXPERIENCE

• 4-10 years professional hardware design experience

• 3+ shipped production products from concept to market

• Expert proficiency with Altium Designer and KiCad

• Multi-layer PCB design (4-8 layers) with signal/power integrity expertise

• Complex analog and mixed-signal circuit design

• SoC/microcontroller selection and integration (ARM Cortex, TI, NXP, STM32)

• IoT connectivity design (WiFi, BLE, cellular)

• Sensor interface and signal conditioning design

• FCC, CE, and medical device compliance experience

• SPICE simulation and design verification
