HV Component Expert – DC/DC Converter高压电气部件专家（DC/DC转换器）

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 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.

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; approve technical concepts and drive 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 and secure design-to-cost and industrialization readiness.
• Validation, Safety, Quality & Complex Issue Resolution: Define risk-based validation and evidence strategies covering electrical performance, efficiency, EMC, thermal behavior, insulation, diagnostics, functional safety interfaces, reliability, and vehicle integration. Lead root-cause analysis and corrective actions.
• 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.
• 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. Mentor engineers and establish reusable methods and lessons learned.

Qualifications

• Master's degree or above in Electrical Engineering, Power Electronics, Automotive Engineering, Control Engineering, or a related field.
• 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.
• Expert-level knowledge of automotive DC/DC converter topologies, magnetic components, control strategies, gate driving, power semiconductors, and protection concepts.
• Strong knowledge 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.
• Knowledge of functional safety, cybersecurity interfaces, CAN communication, diagnostics, AUTOSAR-related interfaces, and tools such as CANoe, CANape, or DTS Monaco.
• Native-level Chinese and fluent English; German is an advantage. Willingness to travel domestically and internationally and a valid driving license.

Benefits

Benefits include flextime, possible hybrid work, health benefits, mobility offers, employee discounts, parking, an in-house doctor, good public transport, a barrier-free workplace, and a canteen and café.
