• Rapidly prototype hardware systems integrating:
• Accelerometers
• Gyroscopes
• Microphones
• Cameras
• NOR Flash and other memory
• Additional sensors and peripherals
• Perform hardware bring-up, validation, and debugging
• Collaborate closely with firmware engineers to:
• Optimize power consumption
• Ensure reliable sensor interfacing and data acquisition
• Improve wireless performance (range, throughput, stability)
• Test and validate hardware and firmware performance, including:
• Power profiling
• RF performance (range, packet loss, throughput)
• Signal integrity
• Generate detailed test reports with actionable insights
• Develop and maintain mechanical test jigs and fixtures for:
• Device validation
• Repeatable testing
• Data collection setups
• Coordinate with EMS (Electronics Manufacturing Services) partners in China for:
• Prototype builds
• DFM (Design for Manufacturing) feedback
• Production scaling and issue resolution
  

Required Skills & Qualifications

• Strong experience in low-power hardware design for battery-operated devices
• Proven expertise in RF and antenna design, including:
• Antenna selection, matching, and tuning
• RF measurement tools (VNA, spectrum analyzer, etc.)
• Hands-on experience with 4+ layer PCB design tools (e.g., Altium, KiCad, OrCAD)
• Deep understanding of:
• Controlled impedance and stack-up design
• EMI/EMC considerations
• Signal and power integrity
• Experience in BOM management with cost and supply-chain awareness
• Strong experience in schematic design and hardware architecture
• Experience with sensor integration and mixed-signal systems
• Practical experience in hardware debugging and validation
• Ability to interpret and collaborate on firmware-hardware interfaces (SPI, I2C, UART, etc.)
• Familiarity with DFM/DFA best practices
  

Preferred Qualifications

• Experience working on BLE/Wi-Fi-based embedded products
• Familiarity with Nordic Semiconductor (nRF) platforms or similar SoCs
• Knowledge of power optimization techniques at both hardware and system levels
• Basic understanding of firmware workflows and constraints
• Experience with mechanical design concepts (for test fixtures or enclosures)
• Exposure to camera interfaces (e.g., MIPI CSI) and audio front-end design
• Experience with compliance testing (CE, FCC, etc.)
• Experience in wearable or compact IoT device design
• Experience in mass production and scaling hardware
  
  

Soft Skills

• Strong cross-functional collaboration skills (especially with firmware teams)
• Detail-oriented with a focus on design robustness and reliability
• Strong problem-solving and debugging mindset
• Effective communication and documentation skills
  
  

Cross-Functional Collaboration

• Work closely with firmware engineers to co-design power-efficient systems
• Ensure hardware supports high-frequency data acquisition and streaming
• Align on RF performance tuning and BLE/Wi-Fi optimization
• Enable efficient sensor data pipelines and storage systems
• Collaborate with Motion Algorithm Engineers to:
• Optimize algorithms for embedded deployment
• Ensure real-time performance and efficiency
• Jointly debug system-level issues across hardware and firmware
  

Key Priority Requirements

• Expertise in Low power electronics and battery powered devices
• Expertise in Antenna / RF Design for BLE, WiFi and other wireless systems
• Expertise in PCB design for 4 layers or more
• Expertise in rapid prototype development
