About Aptiv

Aptiv is a global technology company focused on safer, greener and more connected mobility. Aptiv Connection Systems’ Chennai Engineering Center supports end-to-end product development, from concept and detailed design through prototype build, verification and validation, for global automotive OEMs.

Role Purpose

Serve as the technical authority for the architecture, design, analysis and verification of automotive high-voltage power-electronics hardware, including 400 V and 800 V on-board chargers (OBCs), high-voltage-to-low-voltage DC/DC converters and integrated power-conversion systems. This is a hands-on individual-contributor role focused on circuit-level technical leadership, design quality, customer and supplier engagement, and cross-functional engineering delivery. It does not include direct people-management responsibility.

Key Responsibilities

• Own hardware architecture and circuit design for 400 V/800 V power-conversion products, including 6.6 kW, 11 kW and 22 kW OBCs and 3 kW to 5 kW HV-LV DC/DC converters.

• Develop and review power stages, gate-drive circuits, current and voltage sensing, auxiliary supplies, protection, isolation, communication and control interfaces.

• Evaluate relevant architectures and technologies such as bidirectional OBC, PFC, LLC/CLLC, phase-shifted full bridge, dual-active bridge, silicon carbide (SiC), gallium nitride (GaN) and integrated X-in-1 solutions.

• Perform worst-case circuit analysis, component-tolerance analysis, derating, thermal and loss calculations, Six Sigma/capability studies and circuit simulations using Maple, SPICE-based tools or equivalent simulation environments.

• Convert system and customer requirements into hardware requirements, block diagrams, interface definitions, design specifications and verification criteria; maintain requirements and traceability in Polarion or equivalent tools.

• Lead schematic design, component selection, design reviews and release activities in accordance with the V-model and Automotive SPICE practices.

• Collaborate with systems, embedded software, mechanical, thermal, ECAD, EMC, manufacturing, quality, sourcing and program teams to optimize performance, packaging, manufacturability, cost and schedule.

• Define hardware verification and validation plans, support prototype builds, supervise laboratory testing and resolve issues identified during DV/PV, production launch and field operation.

• Support DFMEA, design reviews, root-cause analysis and corrective actions for hardware, manufacturing, warranty and customer issues.

• Assess OEM requirements and engineering-change requests, including impact on circuit performance, safety, EMC, validation, timing and cost.

• Engage with component, PCB and PCBA suppliers for technical evaluation, sourcing, prototype readiness, design-for-manufacturing and issue resolution.

• Prepare high-quality design documentation, analysis reports and technical presentations; clearly communicate design decisions and risks to customers and internal stakeholders.

• Mentor engineers, allocate technical work, establish review discipline and drive timely closure of design and validation deliverables.
