关于这个职位

负责剩余电流动作保护器(RCD)等电气产品的硬件研发工作,包括电路设计、仿真验证及EMC/浪涌抗扰度设计

需独立完成原理图与PCB布局,处理弱信号检测与电源管理,并支持产品认证、量产维护及跨部门项目协调,确保产品符合IEC国际标准

最低要求

Bachelor's degree or above in Electronics, Electrical Engineering, Automation, or a related field.

Strong skills in schematic design and PCB layout, with solid circuit calculation ability. Proficient with EDA tools and circuit simulation tools.
Expert in analog circuit design, with the ability to detect and condition weak signals.
Familiar with how residual current detection works. Knowledge of zero-sequence current transformers, magnetic materials and fluxgate technology.
Knowledge of power supplies, magnetic components and embedded systems.
Familiar with EMC and surge protection theory, testing and corrective actions.
Familiar with industrial communication protocols and IoT applications, such as Modbus and CAN.
The following are a plus:
Familiarity with the IEC 60947 series of low-voltage product standards, especially the residual current protection requirements (IEC 60947-2 Annex B and Annex M)
Development experience with RC, RCD (including Type B) or electronic trip units
Knowledge of DFMEA and reliability design
Good spoken and written English, able to work with global teams.
Excellent cross-functional communication and coordination skills.
Able to work independently and perform well under pressure.
+ years of hardware development experience.

工作职责

Take part in project evaluations and technical feasibility studies for residual current protection products. Propose sound hardware solutions.

Design residual current detection circuits for Type A, B and other types. This includes signal conditioning for zero-sequence current transformers and fluxgate-based DC detection. Select and match magnetic cores and current transformers.
Design trip control circuits. This includes dedicated RCD IC or MCU-based solutions, trip actuator drive, test button circuits, and low-power supply circuits that work across a wide voltage range.
Design and verify operating characteristics, including rated residual operating current (IΔn), operating time, time-delay operation, and operating thresholds at different frequencies and waveforms.
Own surge immunity and noise-immunity design. The product must neither trip falsely nor fail to trip under impulse voltage, ring wave and EMC disturbances.
Perform calculations, simulations and test verification according to design requirements. Create and maintain complete design documentation, including schematics, BOM, design calculations, DFMEA and test reports.
Support type testing and certification to the IEC 60947 series (e.g., IEC 60947-2 Annex B and Annex M), and drive any corrective actions.
Maintain products in series production, resolve design-related quality issues and support product lifecycle management.
Support cost and quality optimization, including component selection, validation of alternative components and technical communication with suppliers.
Interpret customer requirements, translate them into technical specifications and evaluate design concepts.
Coordinate with cross-functional and global teams to plan and manage R&D projects.
Complete other tasks assigned by the company.
