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

Job description

Tasks 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

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.
