Job Overview
We are looking for a highly skilled Hardware Engineer with deep expertise in
low-power electronics,
RF design, and
embedded hardware systems. This role involves end-to-end hardware development—from schematic and PCB design to prototyping, testing, and production—while working closely with firmware engineers to build optimized, high-performance wireless devices.
Key Responsibilities
- Design and develop low-power, battery-operated embedded hardware systems
- Lead RF and antenna design for wireless systems including:
- Bluetooth Low Energy (BLE)
- Wi-Fi
- Other RF protocols (as applicable)
- Design multi-layer PCBs (minimum 4 layers) with focus on:
- Controlled impedance routing
- RF layout best practices
- Signal integrity and noise minimization
- Antenna matching and tuning
- Create and maintain:
- Schematics
- PCB layouts
- Bill of Materials (BOM) with cost and availability optimization
- 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
