REQUIREMENTS

• Masters degree or above in mechanical Engineering or other related fields.
• Min 8 years of experience in designing, analysing and optimizing arc-related parts such as arc-extinguishing systems and conductive circuits of low-voltage switch products, as well as improving the arc-extinguishing performance of products to meet application requirements.
• Min 8 years of experience in design and testing of circuit breakers, experience in DC breakers is a strong plus.
• Experience in building test set-ups to test different breaker concepts.
• Experience in research, development and application of key technologies and devices in this field.
• Solid basic knowledge of mechanics.
• Good teamwork spirit, strong learning ability and English communication and writing skills.

• Design arc quenching chambers and contact systems, perform multibody simulations and develop the CAD drawings to be able to interrupt fault currents fast for different voltage and current ratings
• Design, simulate, and manufacture the actuator needed to drive a contact system.
• Explore the arc mechanism, overcome technical barriers such as zero flashover, zero breakdown, and zero emission under high voltage and large short-circuit current, and provide key arc extinguishing solutions for new power distribution devices used in digital energy scenarios.
• Propose innovative technical solutions to speed up the arc interruption process and successfully interrupt DC fault currents in a fast and reliable manner.
• Discuss with suppliers and manage the fabrication process of the parts needed to assemble the breaker.
