Embedded Firmware Engineer

SUMMARY:
Our client is seeking  a Lead Embedded Hardware Engineer to design and develop a highly miniaturized, high-performance avionics hardware platform. You will own the full hardware lifecycle from schematic design and PCB layout through to prototyping, testing, and mass production.
You will be responsible for developing:

• The AeroNode processing hub (STM32-based flight computation system)
• The H1 headset electronics (wearable biometric and audio DSP system)
• High-density, safety-critical embedded PCB systems for aviation applications

POSITION INFO:

Required Experience & Skills

• 5–7+ years in embedded hardware and PCB design
• Strong experience with high-density, multi-layer PCB layout
• Proven ability in high-speed digital design and signal integrity
• Strong knowledge of STM32 microcontroller architecture
• Experience with EMI-sensitive designs (GPS, magnetometers, RF systems)
• Hands-on hardware debugging capability
• Experience with wearable or rigid-flex PCB design

Advantageous (Bonus) Experience

• Drone or aviation hardware experience (Pixhawk, CubePilot, FMUv6x)
• Avionics, aerospace, or safety-critical embedded systems
• Experience with MRAM, eMMC, or high-reliability storage systems
• Familiarity with EKF-based navigation or flight control systems

Key Responsibilities

• End-to-end PCB design using Altium Designer or KiCad
• Design of multi-layer, high-density embedded avionics hardware
• Integration of sensors and modules including IMUs, barometers, magnetometers, GNSS, and wireless communication systems
• High-speed interface design (SPI, I2C, USB, SDIO) with strong signal integrity control
• EMI/EMC mitigation, particularly for GPS and magnetometer performance
• Design of rigid-flex PCBs for wearable electronics
• Collaboration with mechanical engineers on vibration, thermal, and enclosure design
• Support prototyping, debugging, and validation using lab equipment (oscilloscopes, logic analysers)
• Manage DFM/DFA and transition from prototype to production
