Chapter Lead
__
In this role, you will have the opportunity to contribute to ABB’s success with technology, software, product, and system development. Each day, you will identify and implement innovative solutions to relevant problems. You will also showcase your expertise by providing ideas and by being able to work both independently and as a part of a Research & Development (R&D) team.
The work model for the role is: onsite
This role is contributing to the ELSP in Jiangmen / Xiamen .
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.
Our team dynamics (Optional)
You will join a {talented, high performing} team, where you will be able to thrive.
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.
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.
5+ years of hardware development experience.
