Objective of the Position

China is one of the most important markets for Mercedes-Benz and a key driver of innovation in electric mobility. The rapid development of power electronics, electrified low-voltage networks, and localized supply chains creates significant opportunities and challenges for future vehicle platforms.
The Charging & High Voltage Systems team is responsible for the development, localization, validation, and innovation of high-voltage charging and power-conversion components in China.
This expert position holds end-to-end technical responsibility for high-voltage DC/DC converters, including HV-to-12 V and HV-to-48 V conversion as well as dual-output and integrated power-electronics concepts for Mercedes-Benz vehicle platforms.
The role acts as the technical authority for DC/DC architecture, requirements, supplier concepts, design maturity, validation, industrialization, and issue resolution. It independently steers complex cross-functional decisions, defines technical roadmaps, transfers China-market innovation into global development, and coaches engineers and project partners in the DC/DC domain.
The position ensures robust delivery against Mercedes-Benz targets for safety, quality, performance, efficiency, package, cost, and timing, while aligning China suppliers and global development teams.
 

Key Responsibilities

• DC/DC Technical Authority & End-to-End Component Ownership
  Own the DC/DC component from concept to series release. Define architecture, requirements, performance targets, interfaces, and acceptance criteria; independently approve technical concepts and drive robust decisions across the lifecycle.
   
• Supplier Development, Design Maturity & Localization
  Lead supplier technical steering, concept and design reviews, maturity assessment, change control, and escalations. Evaluate supplier proposals and localization options, provide technical input to sourcing decisions, and secure design-to-cost and industrialization readiness.
   
• Validation, Safety, Quality & Complex Issue Resolution
  Define risk-based validation and evidence strategy covering electrical performance, efficiency, EMC, thermal behavior, insulation, diagnostics, functional safety interfaces, reliability, and vehicle integration. Lead root-cause analysis and corrective actions for critical development and field issues.
   
• DC/DC Technology Roadmap & Global Expert Contribution
  Benchmark China and global technologies and define roadmaps for HV-to-12 V, HV-to-48 V, dual-output, bidirectional, and integrated power-electronics concepts. Translate market and supplier innovation into concrete Mercedes-Benz platform proposals and standards.
   
• Cross-functional Leadership, Governance & Capability Building
  Lead alignment with vehicle architecture, LV/HV power network, battery, eDrive, thermal, EMC, software, purchasing, quality, manufacturing, and project teams. Represent the DC/DC domain in management reviews, mentor engineers, and establish reusable methods and lessons learned.
   

Qualifications

Education：Master's degree or above in Electrical Engineering, Power Electronics, Automotive Engineering, Control Engineering, or a related field.

Experience：
 

• At least 7 years of relevant experience in automotive power electronics or high-voltage component development, including at least 5 years of direct DC/DC converter responsibility.
• Proven end-to-end ownership of at least one series-development DC/DC project from concept and requirements through supplier development, validation, release, and industrialization.
• Demonstrated experience leading complex technical decisions and supplier escalations across hardware, software, controls, thermal, EMC, functional safety, diagnostics, quality, and manufacturing interfaces.
• Experience with BEV, PHEV, or REEV vehicle programs and global, cross-functional development organizations.
  Experience providing technical coaching, design-review leadership, or expert guidance to engineers and project teams.

Specific Knowledge

• Expert-level knowledge of isolated and non-isolated automotive DC/DC converter topologies, magnetic components, control strategies, gate driving, power semiconductors, and protection concepts.
• Deep understanding of HV-to-12 V, HV-to-48 V, dual-output DC/DC, bidirectional conversion, voltage regulation, load transients, efficiency mapping, derating, thermal design, insulation coordination, and HV/LV interface requirements.
• Ability to assess topology and design trade-offs involving efficiency, power density, cooling, EMC, acoustics, reliability, package, cost, and manufacturability; practical knowledge of Si, SiC, and GaN device applications.
• Strong competence in component and system requirements, DFMEA, design reviews, tolerance analysis, root-cause analysis, validation strategy, lifecycle robustness, and technical release decisions.
• Solid knowledge of functional safety, cybersecurity interfaces, CAN communication, diagnostics, AUTOSAR-related interfaces, and tools such as CANoe, CANape, or DTS Monaco.
• Working knowledge of relevant automotive and electrical safety standards and internal specifications; ability to translate standards into clear supplier requirements and verification evidence.
• Proven supplier steering and technical project leadership, including proposal assessment, sourcing support, change control, risk management, maturity tracking, and escalation management.
• Strong analytical judgment and fact-based decision-making; able to communicate complex technical topics clearly to management, global engineering teams, and suppliers.
• Native-level Chinese and fluent English; German is an advantage. Willingness to travel domestically and internationally; valid driving license.
