- 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.
- 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.
- Competitive compensation & benefit package
- Possibility to work in an international environment with multicultural team
- Interesting and challenging career in a successful leading global organization
- Trainings and professional development
