22090-Hardware Engineer

该职位来源于猎聘 We are seeking a hardware engineer to lead the integration development of X-ray detector modules (based on purchased PD modules) and the full hardware development of Check Weigher products. This role will bridge the technical needs of both product lines, ensuring robust, cost-effective, and market-ready solutions. The engineer will oversee end-to-end hardware development—from requirements analysis to prototyping, testing, and mass production—while collaborating with cross-functional teams to deliver high-performance products for industrial and medical applications. Principal Duties and Responsibilities:

• X-ray Detector Module Integration Development
• Module Selection & Design:  Source and evaluate commercial PD (Photon Detection) modules (e.g., from Hamamatsu, Teledyne) based on performance (sensitivity, resolution), cost, and compatibility with target applications (industrial inspection/medical imaging).  Design custom PCBs for PD module integration, including signal conditioning circuits (amplification, filtering), power management (voltage regulation), and thermal management (heat dissipation).
• System Integration & Testing:  Interface the PD module with X-ray system components (e.g., high-voltage power supply, data acquisition board) to ensure signal integrity and system stability.  Conduct prototype testing: validate image quality (resolution, noise), radiation safety (dose control), and environmental robustness (temperature/humidity resistance).  Optimize designs based on test results (e.g., reduce noise via circuit tweaks, improve heat dissipation with thermal pads).
• Mass Production Support:  Define BOM (Bill of Materials) and Gerber files for PD module assembly.  Collaborate with suppliers to qualify components (e.g., PD modules, capacitors) and resolve production issues (e.g., soldering defects, component mismatches).
• Check Weigher Hardware Development
• Requirement & Architecture Design:  Translate product requirements (e.g., weighing accuracy ±0.1g, detection speed 200 items/min, multi-scale compatibility) into hardware specifications (sensor type, signal processing bandwidth, communication protocols).  Design system architecture: select sensors (strain gauge, capacitive), design signal conditioning circuits (amplifiers, filters), and integrate motion control modules (stepper motor drivers).
• PCB Design & Prototyping:  Develop schematics and PCB layouts for sensor interfaces, signal processing, and motion control modules using Altium Designer or Cadence.  Prototype and test hardware: validate sensor accuracy (e.g., linearity, repeatability), communication reliability (RS485/CAN), and environmental performance (vibration resistance, wide temperature range).
• Field Validation & Iteration:  Support field testing with customers to identify issues (e.g., weighing drift, sensor noise) and refine designs (e.g., adjust amplifier gains, add vibration damping).  Optimize for cost and manufacturability (e.g., source alternative sensors, simplify PCB layouts).
• Cross-Functional Collaboration & Documentation
• Work with software teams to define hardware-software interfaces (e.g., SPI/CAN protocols, data formats) and debug integration issues.
• Collaborate with test teams to develop validation plans (EMC, reliability, environmental) and analyze test results.
• Document technical specifications, BOMs, and test reports; maintain a knowledge base for design best practices and common issues. Qualifications Education & Experience
• Bachelor’s degree or higher in Electrical Engineering, Automation, or related field.
• 3+ years of hardware development experience, with a focus on sensor integration (PD modules or industrial sensors) and/or weighing equipment hardware. Technical Skills
• Proficiency in analog/digital circuit design, with hands-on experience in Altium Designer or Cadence for PCB layout
• Strong understanding of sensors (PD modules, strain gauges), signal conditioning (amplifiers, filters), and power management.
• Familiarity with EMC/EMI design standards (e.g., IEC 61000) and industrial/environmental testing (e.g., IEC 60068).
• Experience with debugging tools (oscilloscopes, logic analyzers, spectrum analyzers) and component sourcing/qualification. Preferred Qualifications
• Experience with X-ray detector integration (medical or industrial) or Check Weigher hardware development.
• Knowledge of ISO 13485 (medical devices) or IATF 16949 (automotive) quality standards.
• Familiarity with C/C++ for basic firmware interaction or hardware debugging.
